Background: The SYNCHRONOUS-study investigates simultaneous ASV-ablation with great saphenous vein (GSV) treatment in endovenous laser ablation (EVLA) for preventing varicose vein recurrence. This sub-study examines complication rates associated with prophylactic ASV-ablation. Methods: Among 1173 patients with refluxing GSV, 604 underwent GSV-ablation only, and 569 received additional ASV-ablation. Complication rates were compared over 6 months. Results: Approximately 80% of patients were complication-free with minor bruising and dysesthesia being most common complications. After 6 months, additional prophylactic ASV-ablation did not increase the rate of complications compared to GSV-only treatment. Conclusion: The 6-months follow-up data suggests that prophylactic ASV-closure, alongside GSV-treatment, is safe, with similar complication rates to GSV-only EVLA. [ABSTRACT FROM AUTHOR]

Reversed great saphenous vein (GSV) graft is widely used for revascularization in limb-sparing surgery for sarcoma invading great vessels. However, a mismatch in caliber between the reverse graft and cut end of the artery can threaten graft patency. Recently, we introduced the use of a venous valvulotome to allow nonreversed GSV graft. The purpose of this study was to evaluate the safety and versatility of this technique. We retrospectively compared long-term patency and limb salvage rates between nonreversed GSV and reversed GSV in patients undergoing limb-sparing surgery for sarcoma. Thirty-seven patients were included, with 21 in the nonreversed GSV group and 16 in the reversed GSV group. Patient characteristics, surgical details, and complications were reviewed from the hospital records. The patency of the reconstructed vessels was assessed using contrast-enhanced CT or MRI. Statistical analyses, including Kaplan–Meier survival analysis, were employed for comparisons. The median follow-up was 38 months. Overall graft patency was 90.4% (19 of 21 patients) in the nonreversed GSV group and 81.2% (13 of 16) in the reverse GSV (RGSV) group. In the nonreversed GSV group, there was 1 case of graft occlusion each in the acute and chronic phases, but limb circulation remained intact and all limbs were spared. Nonreversed GSV grafting with valvulotome offers a safe and versatile alternative to reversed GSV grafts in limb-sparing sarcoma surgery. It eliminates the need for vein reversal and minimizes diameter mismatch, potentially expanding the indication for autologous revascularization to previously ineligible cases. [ABSTRACT FROM AUTHOR]

The recent Best Endovascular vs Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) study showed that bypass was superior to endovascular therapy (ET) in patients with chronic limb-threatening ischemia (CLTI) deemed suitable for either approach who had an available single-segment great saphenous vein (GSV). However, the superiority of bypass among those lacking GSV was not established. We aimed to examine comparative treatment outcomes from a real-world CLTI population using the Vascular Quality Initiative-Medicare-linked database. We queried the Vascular Quality Initiative-Medicare-linked database for patients with CLTI who underwent first-time lower extremity revascularization (2010-2019). We performed two one-to-one propensity score matchings (PSMs): ET vs bypass with GSV (BWGSV) and ET vs bypass with a prosthetic graft (BWPG). The primary outcome was amputation-free survival. Secondary outcomes were freedom from amputation and overall survival (OS). Three cohorts were queried: BWGSV (N = 5279, 14.7%), BWPG (N = 2778, 7.7%), and ET (N = 27,977, 77.6%). PSM produced two sets of well-matched cohorts: 4705 pairs of ET vs BWGSV and 2583 pairs of ET vs BWPG. In the matched cohorts of ET vs BWGSV, ET was associated with greater hazards of death (hazard ratio [HR] = 1.34, 95% confidence interval [CI], 1.25-1.43; P <.001), amputation (HR = 1.30, 95% CI, 1.17-1.44; P <.001), and amputation/death (HR = 1.32, 95% CI, 1.24-1.40; P <.001) up to 4 years. In the matched cohorts of ET vs BWPG, ET was associated with greater hazards of death up to 2 years (HR = 1.11, 95% CI, 1.00-1.22; P =.042) but not amputation or amputation/death. In this real-world multi-institutional Medicare-linked PSM analysis, we found that BWGSV is superior to ET in terms of OS, freedom from amputation, and amputation-free survival up to 4 years. Moreover, BWPG was superior to ET in terms of OS up to 2 years. Our study confirms the superiority of BWGSV to ET as observed in the BEST-CLI trial. [ABSTRACT FROM AUTHOR]

Objectives: The great saphenous vein is the lower limb's longest and thickest-walled superficial vein. Its anatomy is complex, while its anatomical variations are widespread. This study aimed to illustrate the anatomy and variations of the great saphenous vein at the saphenofemoral junction. Methods: The study was conducted on 75 fresh-frozen cadaveric lower limbs. Cadavers with evidence of prior leg surgery or trauma and any congenital abnormality or gross deformity were excluded. The saphenofemoral junction was studied in detail with emphasis on the number, incidence, draining pattern of tributaries, and duplication of the great saphenous vein. Results: Out of the 75 cadaveric lower limbs, 57.3% were obtained from males, and 42.7% were obtained from females. The mean age of the cadaveric lower extremities was 66.6 years (range 42–91). The number of tributaries at the saphenofemoral junction varied from 0 to 7, with a mean of 3.8. The most frequent number of branches was 4–5 in 61.3% of cases. The most consistent tributary was the superficial external pudendal vein, while the posterior accessory great saphenous vein was the least frequent tributary. 80% of the branches drained into the saphenofemoral junction directly (53.3%) or by a common trunk (26.7%%). The most frequent common trunk was the superficial epigastric and superficial circumflex iliac vein (10.7%). The rest 20% of the tributaries drained directly into the common femoral vein. The commonest branch reaching the common femoral vein was the superficial external pudendal vein (10.7%). Duplication of the great saphenous vein was observed in 2.7% of the cases. Conclusions: There is a significant variation of tributaries at the saphenofemoral junction regarding the number, incidence, draining pattern of branches, and duplication of the great saphenous vein.

Veins of the lower extremity can be categorized into three hierarchically ordered groups: the epifascial, the interfascial, and the deep ones. In the past, the interfascial veins, e.g., the great saphenous vein, were categorized as superficial veins. But nowadays, experts recommend regarding these veins as a separate group because of their unique topography and clinical relevance. In order to better understand the venous anatomy of the lower limbs, which is highly variable, one should also comprehend their embryological development. Venous embryogenesis in the lower limb consists of three stages. During the first stage the primitive fibular vein is the main vein of the extremity. During the second stage it is replaced by the axial vein and finally by the femoral vein. In some adult individuals this embryonic or fetal venous anatomy is still present. Unfortunately, current anatomical textbooks and atlases, as well as traditional cadaver dissections, are not very useful regarding these issues. Therefore, undergraduate teaching of anatomy can be challenging. New educational tools, such as ultrasonography, seem indispensable to teach the anatomy of these veins properly.

Objective: By incorporating an endovascular component into Great Saphenous Vein stripping, EndoVenous-assisted Invaginated Stripping (EVIS) aims to make the procedure minimally invasive. A study was conducted to investigate the surgical intervention. Methods: Sketches and videos were used to illustrate the technical aspects of EVIS. A prospective cohort study included 20 patients with chronic venous insufficiency (CVI). Results: EVIS is performed as a day-surgery. Technical success was 100%, and no complications were recorded. The mean operative time was 45 minutes, intraoperative pain score was 4.8, post-operative pain was 2.5, 1.8, 1.2, 0.5 at 48 hours, 1, 4, and 12 weeks, respectively. The mean blood loss was 15 mL, and the mean length of the GSV strapped was 19 cm. The follow-up duplex showed a reduction in the diameter of the residual GSV stump. Conclusions: EVIS is a combination of standard techniques that may prove valuable in managing CVI. [ABSTRACT FROM AUTHOR]

The great saphenous vein (GSV) is extremely commonly used as a conduit in lower extremity revascularization due to the appropriate diameter of the vein (in most cases) as well as the histological characteristics of the venous wall. Aneurysmal degeneration of the GSV in the postoperative period after bypass surgery is a rare complication. It is explained by the fact that autovenous reconstructions are at risk of degenerative changes. Complications that accompany aneurysmal degeneration of autovenous reconstruction are rupture with hemorrhage, thrombosis, and distal embolization of the foot arteries. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to investigate the impact of post-interventional compression therapy on clinical outcomes after endovenous laser ablation (EVLA) of incompetent saphenous veins. Methods: This prospective, controlled, multicenter study in Germany involved 493 varicose vein patients followed-up for 6 months. Results: Compression therapy significantly reduced symptoms compared to no compression (VCSS: 1.4 ± 1.6 vs 2.2 ± 2.2; p =.007). Post-interventional therapy duration of up to 14 days was found to be most effective for improving patient-reported disease severity (p <.001) and higher quality of life (p =.001). Patient compliance was high (82%), and non-compliance was linked to worse disease severity (VCSS 1.4 ± 1.5 vs 2.1 ± 2.3, p =.009). Conclusion: In conclusion, post-interventional compression therapy is beneficial by reducing symptoms and improving quality of life. High patient compliance with the therapy is observed, and non-compliance is associated with worse disease severity. [ABSTRACT FROM AUTHOR]

Objectives: The catheter-directed foam sclerotherapy (FS) and the suggested perivenous tumescent application for great saphenous vein (GSV) diameter reduction are suggested to improve technical and clinical results; yet, their use is reported rather indiscriminately. Our aim is to introduce an algorithm categorising the use of technical modalities accompanying ultrasound-guided FS of the GSV and present the technical efficacy of FS through a 5 F × 11 cm sheath placed at the knee level. Methods: Representative cases of GSV insufficiency were chosen to describe our methodology. Results: Sole sheath-directed FS can achieve complete GSV occlusion proximally at a level comparable to the catheter-directed technique. We apply perivenous 4°C cold tumescent to GSV >6 mm even in the standing position to ensure diameter reduction of the proximal GSV as close to the saphenofemoral junction. We use long catheters only to overcome large varicosities above the knee level that could otherwise compromise the adequate foam infusion from the sheath tip. When GSV insufficiency extends along the entire limb and severe skin lesions preclude the antegrade distal catheterisation, the sheath-directed FS in the thigh can be concomitantly combined with retrograde FS from catheterisation just below the knee. Conclusions: A topology-oriented methodology with sheath-directed FS is technically feasible and avoids indiscriminate use of more complex modalities. [ABSTRACT FROM AUTHOR]

Background: The term Anterior Accessory of the Great Saphenous Vein suggest this is a branch tributary vein despite this vessel's anatomic features of a truncal vein. A multisocietal group suggested to designate this the Anterior Saphenous Vein (ASV). This study was aimed to evaluate its ultrasound anatomy in normal and varicose limbs. Methods: The clinical anatomy of the ASV was evaluated by narrative review of the literature. Additionally, the course of the ASV was evaluated in 62 limbs with no evidence of venous disease and 62 limbs with varicosities. Results: The ASV length, patterns of origin and termination are reported in both normal and patients with varicose veins. Discussion of the patterns is supported by the narrative review of the literature. Conclusions: The ASV must be considered a truncal vein and its treatment modalities should be the same that for the great and small saphenous veins rather than a tributary vein.

Objective: The aim of the study was to evaluate the efficacy and safety of the combination of minimally invasive methods for the treatment of incompetent great saphenous vein and perforating veins. Methods: Between December 2019 and October 2020, F-care radiofrequency ablation combined with ultrasound-guided foam sclerotherapy and residual perforator ligation and concomitant microphlebectomy were adopted for all eligible patients. The clinical symptoms scores, complications, and quality of life were recorded. Results: 49 patients (64 limbs) with a mean age of 63.29 ± 10.14 years, and 60.9% 4 were male. The 1-year truncal closure rate was 63/64 (98.4%). 1 A significant improvement in the Venous Disability Score, the Venous Segmental Disease Score, the Venous Clinical Severity Score and Chronic Venous Disease Quality of Life Questionnaire Score, at 12 months after the combination of minimally invasive treatment, were observed in the study. One patient developed intermuscular vein thrombosis that was successfully managed with rivaroxaban. Conclusions: The combination of minimally invasive methods is a safe and effective method for the treatment of lower extremity varicose veins. Further large-scale, prospective, multi-center studies are needed to further verify the findings of this study. [ABSTRACT FROM AUTHOR]

Venous disorders encompass a diverse range of manifestations and diseases, impacting a significant portion of the population. While life-threatening conditions are uncommon in non-thrombotic disorders, like telangiectasias or uncomplicated varicose veins (VVs), these conditions still have a substantial impact on affected individuals. Ensuring that patients are well informed about their venous disorder is a crucial step in their treatment journey. Providing them with valuable information regarding the disease's natural progression and available therapeutic options plays a pivotal role in optimizing their care. When patients are diagnosed with venous disorders, they often have numerous questions and concerns they want to discuss with their healthcare providers. Addressing these inquiries not only improves patients' knowledge and understanding but also influences their treatment compliance and overall outcomes. Therefore, it is of utmost importance to provide comprehensive explanations that address any doubts, uncertainties, and areas of confusion that patients may have. This report aims to present a concise, practical, and informative guide to venous disorders, focusing specifically on the common questions frequently raised by patients in everyday clinical practice. By serving as a valuable resource for healthcare professionals working in the field of venous diseases, this guide equips them with the necessary tools to effectively address patients' concerns and provide optimal care. By bridging the gap between patients' inquiries and medical expertise, this guide strives to enhance therapeutic outcomes and improve the overall management of venous disorders, ultimately empowering patients in their treatment journey.

Objective: We aim to report on the Laser-Sclerosing Foam Hybrid Treatment (LSFHT) and its outcomes when used on patients with great saphenous vein (GSV) insufficiency. Methods: This was a single center retrospective cohort study on patients with GSV insufficiency that were treated with the LSFHT technique, a surgical procedure that comprises the use of both sclerosing foam and endovenous ablation and avoids the use of tumescent anesthesia. Occlusion rates and complications were reported. Results: 139 legs from 106 patients were operated, achieving a 100% occlusion rate, while only a small burn and 2 popliteal vein thrombosis cases occurred. Conclusion: The study suggests that the LSFHT is a feasible fast procedure that proved both effective and safe for the treatment of GSV insufficiency. [ABSTRACT FROM AUTHOR]

Introduction: Saphenofemoral junction (SFJ) incompetence is the most commonly attributed etiological factor in varicose veins of lower limbs with a consequent increase in the caliber of the great saphenous vein (GSV). This study aimed to assess GSV diameter to determine its cutoff diameter value for predicting reflux at the SFJ, in cases of varicose veins. Methods: This hospital-based prospective study was conducted on 156 patients (245 diseased limbs) over a period of 2 years, involving patients referred from the outpatient department for evaluation of varicose veins or those being evaluated as a part of preoperative assessment. Results: The cutoff value of GSV diameter to detect SFJ incompetence was determined at 5.4 mm with best sensitivity of 74.3%, specificity of 78.5%, and accuracy of 75.1%. Conclusion: GSV diameter assessment is of immense clinical importance as it can help the treating physician to filter out the false-negative cases solely being diagnosed based on reflux at SFJ, especially those with an absence of obvious clinical signs.

Introduction: The objective of this study is to evaluate and compare the effectiveness of endovenous microwave ablation (EMA) and high ligation and strippingn (HLS) of the great saphenous vein (GSV) in the treatment of varicose veins. Methods: We included 182 patients in each EMA and HLS groups. Follow-up outcomes included AVVQ, VCSS, chronic venous insufficiency questionnaire-14 (CIVIQ14) score, clinical recurrence rate of varicose vein treatment, and patient satisfaction during the 1-year follow-up period. Results: At the 1-year follow-up, no significant difference was found in the clinical recurrence rate of varicose veins between the EMA and HLS groups (p =.75). The duration of the operation and the length of hospital stay for patients in the EMA group was shorter than that for the HLS group (p <.01). The Aberdeen Varicose Vein Questionnaire (AVVQ), Venous Clinical Severity Score (VCSS) score, and ecchymosis were lower for patients who underwent EMA surgery (p <.01). Conclusion: Our research results confirm that EMA improves patients' quality of life with lower limb varicose veins, with EMA showing higher patient satisfaction. [ABSTRACT FROM AUTHOR]

Background: Mechanochemical endovenous ablation (MOCA) was introduced to treat superficial venous insufficiency of the lower leg with less pain and haematoma. Long-term outcome is still lacking. The purpose was to report long-term outcome and to analyse possible predictors for failure. Methods: The study was a retrospective pooled analysis of two prospective cohorts previously reported, but with prolonged long-term outcome up to 5-years follow-up. Results: 163 treated legs were analysed. Mean follow-up was 5.4±0.6 years, in which 33 total failures occurred. Four procedures were partially successful. VCSS improved significantly and remained stable after 1 and 2-years, but significantly rose again after 5-years. AVVQ dropped significantly, but increased after 1 year to 4.3 and 6.1 at 5-years follow-up. Conclusion: MOCA was effective with minimal pain perioperative. However, anatomical success deteriorated after 1-year and showed even less results after 5-years, mainly due to partly recanalization, while clinical results were less affected. There were no clear clinical predictors for failure. [ABSTRACT FROM AUTHOR]

Introduction: It has been previously proposed in numerous studies that chronic venous insufficiency (CVI) has similar pathogenesis to varicocele in males. Varicocele has been identified as the most common cause of infertility in men, accounting for 40% of cases. Aim: This study investigates whether varicocele screening should be conducted in patients with CVI and, if so, which patients should undergo such screening. Material and methods: The study included 102 adult male patients with venous insufficiency complaints who presented to the cardiovascular surgery clinic between January 2023 and June 2023. Data were prospectively collected through medical history interviews and Doppler ultrasound measurements performed by a single radiologist. The relationship between non-normally distributed measurement data of the two groups was evaluated using the Mann-Whitney U test, while the association between categorical variables was assessed using the χ² test. ROC analysis was employed for determining predictive value. A type 1 error level of α = 0.05 was adopted. Results: The mean left great saphenous vein (GSV) diameter of those with varicocele (6.6 ±2.3) was significantly larger compared to the mean left GSV diameter of those without varicocele (5.3 ±2.6) (p = 0.004). The area under the ROC curve for left GSV diameter was 67% (p = 0.005). When varicocele screening is performed in patients with a left GSV diameter of 5.35 cm and above, sensitivity is 71.4% and specificity is 61.2%. Conclusions: There is a significant association between left GSV diameter and varicocele (p = 0.004). Varicocele screening can be carried out with 71.4% sensitivity in adult male patients with a left GSV diameter of 5.35 cm and above. Both cardiovascular surgeons and radiologists can conduct varicocele screening by measuring pampiniform veins in patients with a left GSV diameter of 5.35 cm and above. This approach has the potential to reduce the incidence of varicocele and associated infertility. [ABSTRACT FROM AUTHOR]

Objective To evaluate the early clinical effect of the application of endoscopy in coronary artery bypass grafting to obtain the great saphenous vein. Methods A total of 262 patients with great saphenous vein obtained by endoscopy in Nanjing Drum Tower Hospital were used to observe the operation status and incidence of postoperative incision complications from June 2019 to October 2023. Results The time to obtain the great saphenous vein was (39.1±9.2) min, and the length was (30.8±7.6) cm. There was no obvious damage to the wall of the great saphenous vein after removal. Subcutaneous ecchymosis occurred in 13 patients, and it could be absorbed and healed by itself after an average of about 10 days. The pain of the leg incision was not obvious, and there was no incision infection, dehiscence or fat liquefaction. Conclusion Obtaining the great saphenous vein through endoscopy with little trauma can bring good early clinical results and improve patient satisfaction and quality of life.

Vascular leiomyosarcoma LMS. is an extremely rare subgroup of LMSs. Fewer than 50 cases of LMS originating from the great saphenous vein have been reported. In 43% of reported cases, LMS was misdiagnosed clinically. In our case, the patient was initially misdiagnosed as having a thrombosed aneurysm. This misdiagnosis could be due to the rarity of great saphenous vein LMS cases, for which a high index of suspicion is needed, and because no specific radiologic findings have been established for diagnosing LMSs. Masses presenting along the course of vessels should be suspected for malignancy, which can be helpful in performing definitive surgery and avoiding multiple surgeries.

This paper reports on the occurrence of thrombose of the left great saphenous vein (GSV) soon after being given the AstraZeneca vaccine and two recurrent events within three days after the suspension of the anticoagulant. A 53-year-old patient had superficial thrombophlebitis of the GSV in the left leg three days after taking the second dose of the AstraZeneca vaccine for COVID-19 and initiated treatment with rivaroxaban (XareltoTM) 15 mg twice a day, subsequently increasing to 20 mg. After 45 days, the patient contracted dengue and stopped taking the anticoagulant. Two days later, the patient had another thrombosis in the left GSV. The patient is currently in outpatient care with a prophylactic dose of 10mg/day of anticoagulant and undergoes evaluations at three-month intervals. The result of our study is a rare event.

Double‑blind/multicenter/randomized trial protocol. Eligibility criteria: age 18-70 yrs; C2-C5 leg varices secondary to the Great Saphenous Vein (GSV) incontinence; GSV size 6-10mm, at 10cm from the Saphenous-Femoral Junction (SFJ); ostial reflux lasting >0.5 sec at duplex ultrasound; negative reflux elimination test; acceptance of the GSV sparing treatment plus partial/total varicose veins removal. Exclusion criteria: non-isolated GSV reflux; district already treated; pregnancy/lactation; impaired walking ability; deep vein thrombosis/insufficiency; severe comorbidities. Participants recruited from 7 Italian tertiary referral centres. Interventions: crossotomy (no SFJ’s tributaries ligation) vs crossectomy. The study aimed to verify if GSV drainage through the SFJ’s tributaries reduces groin/peripheral recurrences. Primary endpoint: 1-year GSV reflux recurrence, positive to the Valsalva maneuver, originating from the SF. Participants equally randomized. Participants, care givers, and those assessing the outcomes blinded to group assignment.

Application of endoscopic vein harvest (EVH) in infrainguinal bypass surgery generated mixed results. The purpose of this study was to compare outcomes between endoscopic vein harvest and open vein harvest (OVH) in femoral-to-popliteal artery bypass (FPB). Case series analysis that involved all patients undergoing femoral-to-popliteal artery bypass with single-segment great saphenous vein between January 2012 and December 2017. There were 170 femoral-to-popliteal artery bypasses performed in 168 patients who met the inclusion criteria; 25 (14.7%) in EVH group and 145 (85.3%) in OVH group. Chronic limb-threatening ischemia was an indication for surgery in 60% of EVH patients and 79% of OVH patients (15/25; 60% EVH vs 114/145; 79% OVH; p =.08). Mean follow-up was significantly longer for EVH group (65.71 months EVH vs 45.32 months OVH; p =.003). EVH group had a lower wound complication rate (4/25; 16% EVH vs 45/145; 31% OVH; p =.336), especially at the harvest incision site, despite higher rate of obesity amongst EVH patients (15/25; 60% EVH vs 35/145; 24% OVH; p <.001). The reintervention rate was higher in EVH group (10/25; 40% EVH vs 42/145; 29% OVH; p =.38). At 5 years, primary (69.1% EVH vs 67.0% OVH; p =.85), primary assisted (87.6% EVH vs 73.5% OVH; p =.18), and secondary patency rates (87.3% EVH vs 76.7% OVH; p =.25) did not demonstrate significant differences between the groups. Endoscopic vein harvest for femoral-to-popliteal artery bypass decreased the rate and severity of wound complications, but this difference was statistically insignificant. Obese patients are more suitable for endoscopic vein harvest, with relatively lower chances of developing wound infections. Despite the higher rate of reinterventions, endoscopic vein harvest patency rates were in line with those for the open vein harvest group in up to 5 years of follow-up. [ABSTRACT FROM AUTHOR]

Background: We sought to assess the safety and efficacy of endovenous thermal ablation (EVTA) in treating large great saphenous veins (GSV) > 12 mm in diameter. Methods: We performed a systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 for comparative and noncomparative studies depicting EVTA in the treatment of GSV > 12 mm. Primary endpoints included GSV occlusion, technical success, deep vein thrombosis (DVT), and endovenous heat-induced thrombosis (EHIT). We conducted a comparative analysis between GSV > 12 mm and < 12 mm and a meta-regression analysis for two sets of studies, one including the whole dataset, containing treatment arms of comparative studies with GSV < 12 mm and one exclusively for GSV > 12 mm. Results: Seven studies, including 2564 GSV, depicting radiofrequency (RFA) and endovenous laser ablation (EVLA) were included. GSV > 12 mm occlusion, technical success, DVT, and EHIT estimates were 95.9% (95% CI: 93.6–97.8), 99.9% (95% CI: 98.9–100.0), 0.04% (95% CI: 0.0–3.4), and 1.6% (95% CI: 0.3–3.5). Meta-regression revealed a negative association between GSV diameter and occlusion for both the whole dataset (p < 0.01) and the > 12 mm groups (p = 0.04), GSV diameter and technical success for both groups (p < 0.01), (p = 0.016), and GSV diameter and EHIT only for the whole dataset (p = 0.02). The comparative analysis between GSV < 12 mm and GSV > 12 mm displayed an occlusion estimate of OR 1.79 (95% CI: 1.25–2.56) favoring small GSV. Conclusion: Whereas we have displayed excellent occlusion and technical success results for the EVTA of GSV > 12 mm, our analysis has illustrated the unfavorable impact of GSV diameter on occlusion, technical success, and EHIT outcomes regardless of the 12 mm threshold. Potential parameter or device adjustments in a diameter-oriented fashion could further enhance outcomes. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate the efficacy of foam sclerotherapy in the treatment of tortuous Great Saphenous Vein (GSV) insufficiency. Methods: In this prospective non-randomized study 62 patients with tortuous GSV insufficiency were included. All patients were delivered sclerosant agent in the form of foam into the GSV through a cannula above the knee level. Characteristics of patients, diameter of veins, reflux grades, Venous Clinical Severity Score (VCSS) and Clinical, Etiological, Anatomical, Pathological (CEAP) scores, concentration of sclerosant agent, complications and follow-up results were recorded. Results: Foam sclerotheraphy was performed with 100% technical success in all patients at operative room. There were no allergic reactions or neurological complications during and after the operations. Ecchymosis was the most common complication with 37.1% frequency.. VCSS scores significantly decreased from 6.43% to 2.53%, during follow-up from initial admission to sixth months, respectively (P <0.05).In the first month parameters, successful occlusion rate was 88.7%, whereas its rate was 82.3% in sixth month. Recanalization rate significantly increased from 11.3% to 17.7% during follow-up from first to sixth months, respectively (P <0.05). Conclusions: Due to its low complication rate, low cost, acceptable total occlusion rate and reproducibility; Foam sclerotherapy can be considered a reliable treatment for patients with tortuous GSV insufficiency.

Background: To retrospectively analyze the short-term outcomes of catheter-based versus direct foam sclerotherapy when combined with high ligation (HL) for the treatment of great saphenous vein (GSV) incompetence. Methods: From July 2018 to October 2019, a total of 82 lower limbs of 70 patients with GSV incompetence received HL combined with catheter-based foam sclerotherapy (CFS group) or direct foam sclerotherapy (DFS group) for GSV proximal trunk. Among them, 40 limbs of 36 patients were treated with CFS, and 42 limbs of 34 patients were treated with DFS. The occlusion of GSV proximal trunk was evaluated with venous duplex ultrasound examinations; Venous Clinical Severity Scores (VCSS) was used to assess clinical improvement; Aberdeen Varicose Veins Questionnaire (AVVQ) was used to assess quality-of-life scores; and Complications was used for the safety evaluation. Results: At day 7 post-operatively, complete occlusion of proximal trunk of the GSV was achieved in 92.5% legs of the CFS group and 71.4% of the DFS group (p = 0.014). Additionally, anterograde flow was found in 7.5% legs of the CFS group and 26.2% of the DFS group (p = 0.025). No significant differences in the occurrence of complications were observed between the two groups. The median follow-up was 285.5 days in the DFS group and 318 days in the CFS group (p = 0.140). VCSS and AVVQ reduction were significant in both CFS group and DFS group (5.3 ± 2.5, 5.5 ± 2.4, p < 0.001 for VCSS; 15.9 ± 8.0, 16.3 ± 8.6, p < 0.001 for AVVQ), but no significant difference were observed between two groups (p = 0.655 for VCSS, p = 0.934 for AVVQ). Conclusions: Although the occlusion of great saphenous vein proximal trunk were different, two modalities result in similar clinical and quality-of-life improvements. DFS is a feasible alternative to CFS when combined with HL. [ABSTRACT FROM AUTHOR]

Objective: Autologous great saphenous vein (GSV) is considered the conduit of choice for lower extremity bypass (LEB). However, the optimal configuration remains the source of debate. We compared outcomes of patients undergoing LEB using in-situ and reversed techniques. Methods: The Vascular Quality Initiative database was queried for patients undergoing LEB with a single-segment GSV in in-situ (ISGSV) and reversed (RGSV) configurations for symptomatic occlusive disease from 2003 to 2021. Patient demographics, procedural detail, and in-hospital and follow-up outcomes were collected. The primary outcome measures included primary patency at discharge or 30 days and one year. Secondary outcomes were secondary patency, and reinterventions at discharge or 30 days and one year. Cox proportional hazards models were created to determine the association between bypass techniques and outcomes of interest. Results: Of 8234 patients undergoing LEBs, in-situ and reversed techniques were used in 3546 and 4688 patients, respectively. The indication for LEBs was similar between the two cohorts. ISGSV was performed more frequently from the common femoral artery and to more distal targets. RGSV bypass was associated with higher intraoperative blood loss and longer operative time. Perioperatively, ISGSV cohort had higher rates of reinterventions (13.2 vs 11.1%; p = 0.004), surgical site infection (4.2 vs 3%; p = 0.003), and lower primary patency (93.5 vs 95%; p = 0.004) but a comparable rate of secondary patency (99 vs 99.1%; p = 0.675). At 1 year, in-situ bypasses had a lower rate of reinterventions (19.4% vs 21.6%; p =0.02), with similar rates of primary (82.6 vs 81.8%; p = 0.237) and secondary patency (88.7 vs 88.9%; p = 0.625). After adjusting for significant baseline differences and potential confounders, in-situ bypass was independently associated with decreased risks of primary patency loss (HR 0.9; 95% CI, 0.82–0.98; p = 0.016) and reinterventions (HR 0.88; 95% CI, 0.8–0.97; p = 0.014) but a similar risk of secondary patency loss (HR 0.99; 95% CI, 0.86–1.16; p = 0.985) at follow-up, compared to reversed bypass. A subgroup analysis of bypasses to crural targets showed that in-situ and reversed bypasses had similar rates of primary patency loss and reinterventions at 1 year. Among patients with chronic limb-threatening ischemia, in-situ bypass was associated with a decreased risk of reinterventions but similar rates of primary and secondary patency and major amputations at 1 year. Conclusions: In patients undergoing LEBs using the GSV, in-situ configuration was associated with more perioperative reinterventions and lower primary patency rate. However, this was offset by decreased risks of loss of primary patency and reinterventions at 1 year. A thorough intraoperative graft assessment with adjunctive imaging may be performed to detect abnormalities in patients undergoing in-situ bypasses to prevent early failures. Furthermore, closer surveillance of reversed bypass grafts is warranted given the higher rates of reinterventions. [ABSTRACT FROM AUTHOR]

Foam sclerotherapy is considered an acceptable method to treat great saphenous vein (GSV) insufficiency, promoting occlusion of its trunk and eradicating reflux. Yet, certain technical points have not been standardized while issues regarding the ultrasonographic appearance of successful or acceptable GSV obliteration or the end-points of the method are not clearly defined. This article comments on the aforementioned using examples based on personal experience. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to compare patient-reported outcomes after technical success (TS) and technical failure (TF) in treating great saphenous vein incompetence (GSV) with ClariVein. Methods: A subanalysis of a previous trial was conducted on symptomatic GSV incompetence patients who received ClariVein treatment with 2% or 3% polidocanol (POL) and were followed for 6 months. Blinding was implemented for observers and patients, and data from both POL groups were combined. TS was defined as at least 85% occlusion of the treated vein, while TF indicated failure to meet TS criteria. Secondary outcomes included Venous Clinical Severity Score (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and Short-Form 36 Health Survey Questionnaire (SF-36). Results: Among the 364 patients included, the TS rate was 64.5%. Comparison of VCSS, AVVQ, and SF-36 scores between TS and TF groups did not yield significant differences. Conclusion: This study indicates no significant variation in VCSS, AVVQ, and SF-36 scores between patients experiencing TS and TF following ClariVein treatment for GSV insufficiency.

Objective This prospective randomized controlled study aimed to compare the ultrasound-guided (USG) technique with the standard single-wall puncture technique for epicutaneo-caval catheter (ECC) placement in neonates. Study Design A total of 100 neonates were included in this study. All enrolled neonates were randomly divided into two groups (n = 50): the USG group and the control group. The control group underwent standard single-wall puncture for ECC placement procedures, and the USG group underwent USG ECC placement procedures. Results The first attempt success rates (62 vs. 38%; p = 0.016) and the total success rates (92 vs. 74%; p = 0.017) were higher in the USG group than in the control group. The procedure time was shorter in the USG group than in the control group: 351.43 (112.95) versus 739.78 seconds (369.13), p < 0.001. The incidence of adverse events was not significantly different between the two groups. Conclusion Compared with the standard single-wall puncture method, USG cannulation is superior for neonatal ECC placement, with a higher success rate, and decreases the total procedural time. Key Points Establishing ECCs in neonates is challenging and lead to multiple attempts and adverse events. Information on the efficiency of USG dynamic needle tip positioning for ECCs in neonates is lacking. Compared with the standard puncture method, USG cannulation is superior for neonatal ECC placement. [ABSTRACT FROM AUTHOR]

Introduction: Can the tandem arrangement of operating theater setup to perform a surgical drill similar to military, together with safe reuse of single-use items combat the cost of consumables of endovenous laser ablation (EVLA)? Methods: Operation pathway of EVLA consisted of cleaning and draping of patient (step 1), access to the affected vein and infiltration of tumescent local anesthesia (step 2), endovenous ablation (step 3), ultrasound-guided microfoam sclerotherapy (step 4), and chemical sterilization of consumables (step 5). Dedicated theater lists for EVLA were arranged to treat several patients per session in a prearranged operating theater. When the step 5 is completed on the first patient, the step 1 on the next patient was performed using sterilized optical fiber (OF) as a cycle while minimizing patient changeover time. Number of patients treated with each session of OF and time taken for step 1 to step 4 was recorded and analyzed. Results: A total of 140 patients treated using eight OFs during December 2019 to December 2022. Average number of patients treated with a single OF and during a single session of fiber is 17.5 (9–23) and 4.2 (3–7), respectively. Average time taken for step 1 was 7.83 min, step 2 was 7.95 min, step 3 was 1.57 min, and step 4 was 6.36 min. All the procedures were performed using four chemically re-sterilized guidewires and introducer sheaths. Conclusion: Tandem arrangement of operating theater to perform EVLA procedure similar to military drill can optimize the utilization of OFs and consumables.

Abstract The distal great saphenous vein is a popular site for venous access by means of percutaneous cannulation or venous cutdown in a hemodynamically unstable patient. The aim of this study was to precisely define the surface anatomy and dimensions of the distal part of the great saphenous vein to facilitate the aforementioned procedures. Cross-sectional anatomy of the distal saphenous vein was studied in 24 cadaveric ankles sectioned at a horizontal plane across the most prominent points of the medial and lateral malleoli. The curvilinear distance from the most prominent point of the medial malleolus to the center of the saphenous vein, its widest collapsed diameter and skin depth were obtained. The great saphenous vein was located at a mean distance of 24.4 ± 7.9 mm anterior to the medial malleolus. The mean widest collapsed diameter was 3.8 ± 1.5 mm. The mean distance from the skin surface to the vein was 4.1 ± 1.2 mm. These measurements could be used to locate the saphenous vein accurately, particularly in hemodynamically unstable patients with visually indiscernible veins.

The use of total arterial myocardial revascularization in patients with multivessel lesions of the coronary arteries has a number of advantages, namely the duration of functioning or patency of the grafts. The level of total arterial myocardial revascularization implementation in developed and developing countries remains quite low. The aim. Based on the analysis of our own experience, to determine the influence of the technique of total arterial revascularization on the frequency of complications in the early postoperative period. Materials and methods. From February 22, 2016 to December 24, 2020, 390 consecutive patients were operated at the Ukrainian Children’s Cardiac Center. The patients were divided into two groups: participants of the group I underwent total arterial myocardial revascularization, and those includedin the group II underwent conventional coronary artery bypass grafting (CABG). The inclusion criteria were: ischemic heart disease, stable angina or exertional angina, multivascular coronary artery disease, absence of valvular pathology. Results. There was zero 30-day mortality in both groups. The frequency of postoperative bleeding was higher in group II and amounted to 1.6%. Surgical wound complications (infection) were also more common in the group II: 1.2% versus 0.69% (p=0.906) in the group I. Similarly, laboratory parameters such as the level of creatine kinase-MB were almost identical. Conclusions. Total arterial myocardial revascularization is a safe method with good immediate results. The frequency of complications in total arterial myocardial revascularizationdoes not differ from that in conventional CABG. For a wider application of the total arterial myocardial revascularization,it is necessary to continue toconduct studies of the remote postoperative period.

Background Over the years, there have been significant advancements in the treatment of varicose veins. In most surgical settings, the open procedure is still the primary approach. Yet, the popularity of less invasive procedures like EVLA and RFA has produced fantastic outcomes. Objective to assess the safest power of laser which gives maximal effect and least complications in ablation of varicose veins. Methodology A prospective observational study inducing EVLA of different laser power settings (7W & 10W) with preoperative assessment then follow up by CEAP & VCSS and duplex ultrasound measuring great saphenous vein (GSV) diameter and also postoperative complications and time to return to work. Results This study included 50 patients (52 limbs). The Patients were distributed as regard laser power used into two groups (7W, 10W) of 26 limbs for each one. As regard GSV measures changes, there was highly statistically significant decrease in GSV diameter after 1m and after 3m compared to preoperative, with P value P<0.001, among patients group. Also, there is higher number of cases with GSV>10mm in power of laser '10w' group compared to '7w; group, with P value (P<0.001); while there is no statistically significant difference between power of laser 7w versus 10w, because all patients ≤10mm after 1 month and after 3 months, with P value >0.05. Statistically there was no significant difference between 7W & 10W groups as regards time to return to work, CEAP scores and postoperative complications except the significant difference in Pain over the treated vein being less in 7W laser power group. Conclusion For endovenous laser ablation of varicose veins, both 7W and 10W laser power are indicated. They are risk-free and provide the greatest impact with the fewest difficulties for the chosen vein diameter. In our investigation, we came to the conclusion that patients with small GSV diameter required low laser power (7W), while those with large GSV diameter required high laser power (10W).

Objectives This was an open-label randomized comparative two arms study to assess the efficacy and clinical outcome of endovenous thermal ablation on reticular veins and telangiectasias in patients with lower limbs varicose veins with incompetent Sapheno-femoral Junction. Patients and methods A total of 40 patients [15 (37.5%) males and 25 (62.5%) females] with reflux of the long saphenous vein were subjected to radiofrequency ablation (RFA). 20 patients had RFA alone while the other 20 patients underwent RFA and injection sclerotherapy. Then patients were followed up on 1 week after the procedure, 3 months, 6 months, and 1 year by duplex and clinically using venous clinical severity score. Results There were 37.5% males and 62.5% females. There was a statistically significant difference in both groups regarding patients' symptoms (pain, heaviness, and swelling) before and after serial times of follow-up, which was assessed by the VCSS, denoting marked improvement of patients' symptoms. Also, there was a statistically significant difference (P<0.001) concerning duplex results regards the reflux before and following RFA. Reticular veins follow-up, we found that in group A they were present among 35% of patients on 1-week follow-up. This increased to reach 70% after 1 year of follow-up, however, in group B they were absent among all patients on 1 week follow-up. They were present among 15% of patients after 1 year of follow-up. Conclusion RFA with concomitant sclerotherapy for the associated minor veins have proved to be safe, cost-effective and more patient satisfaction than RFA without concomitant sclerotherapy.

Objective: In this study, we present our early outcomes of cyanoacrylate ablation (CA) versus endovenous laser ablation (EVLA) for the treatment of great saphenous vein (GSV) insufficiency in the Chinese mainland population. Methods: We retrospectively analyzed 108 patients (53 patients in the CA group and 55 patients in the EVLA group) with GSV insufficiency who were treated with CA and EVLA between May 2020 and May 2021. The Venous Clinical Severity Score and Aberdeen Varicose Vein Questionnaire were used to assess clinical symptoms and quality of life, respectively. Total closure rates and procedure-related adverse events were also recorded in both groups. Results: There was no significant difference between patients treated with CA or EVLA in terms of demographic and clinical characteristics. The average procedure time was 17 min in the CA group and 35 min in the EVLA group (p < 0.001). The CA group had lower pain scores during the procedure and 3 days afterward than the EVLA group (p < 0.001). At month 12, the CA group had a 90.4% closure rate, while the EVLA group had an 83.0% closure rate, with no significant difference between the two groups (p > 0.05). There was no significant difference in the Venous Clinical Severity Score or Aberdeen Varicose Vein Questionnaire score between the groups (p > 0.05). During follow-up, neither group experienced any significant adverse events, such as pulmonary embolism or deep venous thrombosis. The incidence of ecchymosis and paresthesia was significantly lower in the CA group than in the EVLA group (p < 0.05). Conclusions: Cyanoacrylate ablation has a high feasibility profile and is an effective approach to accomplish complete GSV target vein closure at early follow-up in the Chinese patients. Compared to EVLA, the improvement in quality-of-life outcomes is also sustained and similar, with less pain and fewer complications due to the absence of tumescence anesthesia and postprocedural compression stockings.

Background: Incompetence of the great saphenous vein (GSV) is a global issue and the most prevalent cause of chronic venous disease of the leg. Clinical manifestations range from moderate to severe, including tiredness, heaviness, and irritation, as well as hyperpigmentation and leg ulcers. Significant advancements in GSV ablation employing percutaneous methods, such as endovenous laser ablation, have been made in recent years. (EVLA). The objective of the study is to compare the outcome of the compression dressing for two days vs. seven days after varicose vein surgery. This case control study was performed on the Surgical floor, Mayo Hospital, Lahore, from September 15 to March 15, 2020. Methods: We took a sum of 60 patients admitted from the outpatient department fulfilling the inclusion criteria after the approval of the ethical committee of the hospital. Group-A wore compression dressing for 2 days after surgery and Group-B wore compression dressing for seven days after surgery. Each patient received 1gm paracetamol I/V 8 hourly followed by tab. paracetamol 500mg P/O 8 hourly. Then the outcome of compression dressing was analyzed in the form of mean postoperative pain. The mean pain score was assessed in 1 week. Data were entered in SSPS v23.0 and stratification of pain score was done against age, gender, and grades of varicose veins. A comparison of the two groups was done by applying a ttest. A p-value =0.05 was considered statistically significant. Results: We took a sum of 60 patients with Primary varicose veins based on their eligibility for this study. Patients were divided into two groups, i.e., Group-A (Compression dressing for 2 days) and Group-B (Compression dressing for 7 days). The average ages of patients in group A were 33.4±9.6 years and in group, B was 35.4±9.9 years. A mean pain score of 4.5±1.2 was noted in patients in group-A (Compression dressing for 2 days) while 2.9±0.8 in patients in group B (Compression dressing for 7 days) with a p-value of 0.0001 which is statistically significant. Conclusion: When compression stockings are used for more than two days after the Trendelenburg procedure is done, it can lead to lesser pain and enhanced physical activity in the first-week post operatively.

Abstract Background Donor–recipient diameter discrepancy can be problematic when using an autologous great saphenous vein graft for internal jugular vein reconstruction. A triple-paneled method of saphenous vein grafting is one solution. Case presentation A 54-year-old man with a thyroid papillary carcinoma underwent total thyroidectomy and bilateral neck dissection. An 8-cm segment of the right internal jugular vein was resected. For reconstruction, a 30-cm segment of the great saphenous vein was harvested and divided into three pieces of equal length. After opening each piece longitudinally, they were sutured together in a side-by-side fashion to create a cylinder that was used to reconstruct the internal jugular vein defect. The graft was patent 10 months after the surgery. Conclusion The triple-paneled method is feasible for autologous great saphenous vein graft reconstruction of the internal jugular vein.

Background: Foam sclerotherapy is considered an acceptable method to treat great saphenous vein (GSV) insufficiency, promoting occlusion of its trunk and eradicating reflux. Various modalities and techniques have been described, varying form foam infusion through multiple short cannulae along the GSV to catheter-directed techniques in order to facilitate complete proximal GSV occlusion and improve technical and clinical success. Purpose: To present a modification of the sclerotherapy tehcnique where the presence of venous ulcers poses an extra challenge to the treatment of GSV treatment. Technique: We describe a technical proposal of single foam perfusion through a 11 cm 5F sheath placed at the knee level combined with simultaneous retrograde infusion below the knee. Perivenous tumescent segmental infiltration with cold normal saline at 4°C is applied initially to reduce the diameter in those GSV >6-7 mm. Conclusions: This combination avoids multiple vein cannulation in the GSV along the thigh as well as the need for antegrade infusion when GSV cannulation at the lower tibia is prohibited by a large ulcer area.

A 63-year-old man with a history of bipolar and schizoaffective disorder was admitted to the psychiatry unit. His comorbidities included active smoking, hypertension, diabetes, hyperlipidemia, coronary artery disease after coronary artery bypass grafting, and peripheral arterial disease. During the admission, the patient began to complain of right foot pain at rest. Angiography revealed occlusion of a previously placed right superficial femoral artery and popliteal stents, severe common femoral and distal popliteal stenosis with only a patent posterior tibial (PT) artery runoff. Serial venoplasty was performed and revealed an inadequately sized, ipsilateral great saphenous vein, followed by a delayed femoral–PT in situ saphenous vein bypass. Angiography at 32 months demonstrated a patent femoral–PT great saphenous vein bypass.

Background: Assess the safety and effectiveness of indirect radiofrequency ablation (RFA, Closure FAST) for the treatment of incompetent great saphenous veins (GSVs) with type 1 aneurysms. Methods: This was a retrospective analysis performed in three centers (2007–2021). All patients presenting with saphenous aneurysms close to the junction (within 2 cm) were included. They were treated with RFA. Phlebectomies and/or sclerotherapy were performed during the same treatment session. Duplex ultrasound (DUS) was performed early after the procedure and then, more than a year later. Results: Eight patients (11 limbs) were included between June 2007 and May 2021 with a median diameter of the GSV aneurysm 21 mm (IQR 17.2–23.4). No severe adverse events occurred apart from one endovenous heat-induced thrombosis (EHIT) class III (9.1%). After more than a year (mean 7.2 ± 4.2, median 8 years), none of the aneurysms was present on DUS and the truncal obliteration rate was 100%. Conclusion: RFA appears to be a safe and effective treatment for patients presenting with incompetent saphenous veins with the type 1 aneurysm. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). Materials and methods: All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. Results: During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. Conclusion: RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization. [ABSTRACT FROM AUTHOR]

Vascular elasticity is important in physiological and clinical problems. The mechanical properties of the great saphenous vein (GSV) deserve attention. This research aims to measure the radial elasticity of ex vivo GSV using the optical coherence elasticity (OCE). The finite element model of the phantom is established, the displacement field is calculated, the radial mechanical characteristics of the simulation body are obtained. Furthermore, we performed OCE on seven isolated GSVs. The strain field is obtained by combining the relationship between strain and displacement to obtain the radial elastic modulus of GSVs. In the phantom experiment, the strain of the experimental region of interest is mainly between 0.1 and 0.4, while the simulation result is between 0.06 and 0.40. The radial elastic modulus of GSVs ranged from 3.83 kPa to 7.74 kPa. This study verifies the feasibility of the OCE method for measuring the radial elastic modulus of blood vessels.

Introduction: One of the parts of the coronary artery bypass grafting (CABG) or off-pump coronary artery bypass grafting (OPCAB) process is the collection of vascular material, which is then employed as a coronary aortic bypass due to the large number of coronary vessels necessitating an aorto-coronary bypass. An invasive surgical operation called saphenous vein harvest, also known as the great saphenous vein (GSV), has the potential to cause surgical site infection (SSI). There are currently 2 methods for harvesting GSV: the conventional method open vein harvest (OVH) and the endoscopic, minimally invasive method endoscopic vein harvest (EVH). The clinical issue is whether the GSV harvest approach can influence the patient's lower limb arteriovenous systems and help to lessen postoperative problems. Aim of the research: To analyse the healing of a surgical incision on the lower limb and the effect of GSV harvest methods on the arteriovenous system. Material and methods: In the study period May-September 2022, 60 patients with ischaemic heart disease, who were scheduled for surgical heart revascularization, were included. Clinical information was collected from 60 patients who met the inclusion criteria and were split into 2 groups at random. Results and conclusions: The arteriovenous system of the lower extremities was unaffected by either the OVH or EVH methods utilized to harvest GSV. The OVH approach resulted in a higher rate of SSI in patients with an elevated risk of SSI based on the BHIS scale, particularly in individuals with atherosclerosis of the lower limbs.

To analyze the distribution of incompetent segments in the great saphenous vein (GSV) in Clinical, Etiological, Anatomical, Pathophysiological (CEAP) classification C2 limbs to provide a reference for appropriate diagnosis and treatment planning.We analyzed the distributions of incompetent segments in the GSVs of the C2 lower extremity undergoing duplex ultrasound from September 2017 to December 2023. The examined segments were the saphenofemoral junction (SFJ), GSV at the proximal thigh, GSV at the knee, and GSV below the knee.A total of 696 lower limbs from 540 patients (male 256, female 440) was analyzed. The mean age was 56 (ranging from 18 to 86), and the mean body mass index (BMI) was 24.0 kg/m2. There were 15 types of distribution of incompetent segments within the GSV, with the most common type (32.6%) being reflux from the SFJ to the GSV below the knee. Among the lower limbs with reflux at the SFJ, GSV at the proximal thigh or knee was competent in 10% of lower limbs. In the lower limbs with reflux at the proximal thigh GSV, 26% did not have reflux at the SFJ. The presence of reflux in each segment did not differ by sex, but those with reflux in the below-knee segment were older than those without reflux(p = .003). In each of the three segments above the knee, limbs with reflux had a higher BMI than those without reflux.The most common distribution type was reflux from the SFJ to the below-knee segment, although this only accounted for about one-third of the cases. Various distribution types of incompetent segments within the GSV were identified, suggesting that reflux testing in multiple segments according to the latest guidelines for ultrasound examination of the lower extremity veins is necessary to avoid unnecessary treatment of segments without reflux.

Background: Peripheral arterial disease is a significant health care burden globally. Treatment options for limb salvage include open surgical bypass or endovascular revascularization. One of the vital prerequisite for successful infrainguinal bypass is the availability of good conduit. Not all patients have good quality great saphenous vein of adequate length to facilitate bypass. In these scenarios, splicing of available autologous veins and synthetic graft with vein cuff are alternate options. Aim: To compare the outcomes of infrainguinal bypass done for patients with chronic limb threatening ischemia in two groups In Group I, non spliced GSV was the conduit used. In Group II, either spliced vein graft or synthetic graft with vein cuff was used. Materials and Methods: This is a retrospective study done in a tertiary care centre over a period of 40 months. Ipsilateral Great Saphenous Vein (GSV) was our preferred conduit. In the absence of good calibre GSV, splicing of available autologous veins were done. Only when autologous veins were not available synthetic graft was used with distal vein cuff. Results: A total of 52 patients have undergone bypass during the study period of which 15 patients (28.8%) did not have good calibre GSV. Splicing of autologous veins were done for 10 patients (19.2 %) and synthetic graft with vein cuff was used for 5 patients (9.6%). One year graft patency in group I was 81% and in group II was 66.6%. Limbs were salvaged in 86% of patients in either groups. The mortality rate was 8.1% and 6.6% in groups I & II respectively. Conclusion: When good caliber GSV is not available, splicing of available autologous veins provide comparable patency and should be preferred over synthetic graft. Synthetic graft provides acceptable limb salvage rate when used with an adjunctive procedure like vein cuff for tibial bypasses and should be used when autologous veins are not available or when the patient carries a high risk for major surgery.
