Background Sentinel node biopsy in vulvar cancer is associated with much less morbidity than inguinofemoral node dissection. Our study focused on describing the morphology of superficial lymphatic drainage of the vulva and its relationship to regional nodes, which may facilitate orientation during surgery. Materials and methods In 24 female cadavers, injections of patent blue (at various localizations mediallyunilaterally and bilaterally) were used to visualize the lymphatic drainage of the vulva. After dissection of lymphatic vessels and nodes, their course was documented by photograph and then analyzed. Subsequently, a map of vulvar superficial lymphatics was created. Results The cutaneous and subcutaneous tissue of the vulva primarily drained to superficial inguinal nodes. There was no evidence of a solitary lymph node that drained the unilateral vulva. Each area of the vulva drained to its own lymph node, which was variably localized in the subcutaneous groin around the great saphenous vein. Anastomoses between individual inguinal superficial lymph nodes are likely. Right-left symmetry in the course of lymphatic collectors was not detected. Natural drainage of the medial and paramedial areas to contralateral inguinal nodes was also not detected. The drainage pattern to ipsilateral inguinal nodes was consistent in cadavers without evidence of vulvar disease and may be applicable in the early stages of vulvar cancer. Conclusions There was no evidence of a solitary node that drained the unilateral vulva. Each part of the vulva may drain to a corresponding lymph node in a different localization of the groin. The surgeon should take this variability into account.

The recent development of tough tissue adhesives has stimulated intense interests among material scientists and medical doctors. However, these adhesives have seldom been tested in clinically demanding surgeries. Here we demonstrate adhesive anastomosis in organ transplantation. Anastomosis is commonly conducted by dense sutures and takes a long time, during which all the vessels are occluded. Prolonged occlusion may damage organs and even cause death. We formulate a tough, biocompatible, bioabsorbable adhesive that can sustain tissue tension and pressurized flow. We expose the endothelial surface of vessels onto a gasket, press two endothelial surfaces to the adhesive using a pair of magnetic rings, and reopen the bloodstream immediately. The time for adhesive anastomosis is shortened compared to the time for sutured anastomosis. We have achieved adhesive anastomosis of a great vein in transplanting the liver of a pig. After the surgery, the adhesive is absorbed, the vein heals, and the pig lives for over one month.

Objectives : Spiral saphenous vein grafts (SSVG) or paneled vein grafts (PVG) can be used when the diameter of the autologous great saphenous vein does not match the vessel that needs to be repaired. This study aimed to present early results of complex vascular reconstruction with SSVGs and PVGs in the lower extremities. Methods : From May 2019 through January 2021, six SSVGs and three PVGs were used for vascular reconstruction in nine patients. Patient data were collected retrospectively, including age, gender, cause of vascular pathology, target vessels, concomitant injury, surgical method, additional surgical methods, and hemodynamic status. The Kaplan-Meier method was used to calculate the rate of freedom from reintervention. Results : Among these patients, seven had trauma, one had graft infection, and one had vascular reconstruction after tumor excision. The mean duration of follow-up was 6 ± 6.6 months (range 1–19 months). The rate of freedom from reintervention for any reason was 77.8% at 1 year. Two patients underwent amputation after vascular reconstruction with patent vascular reconstructions. One of the two amputations was performed because of infection, and the other was due to ischemia >24 hours. The success rate of reconstruction was 100%, and the primary patency rate was 100%. The rate of limb salvage was 77.8%. There was no death, bleeding, embolism, skin ulcers, graft-related complication, or aneurysmal dilation during follow-up. Conclusions : SSVG and PVG were associated with low infection rates and satisfactory short-term patency rates. These two grafts may be good choices when there is a diameter mismatch in vascular reconstructions.

Introduction: Treatment for patients with comorbid lymphedema and varicose veins is controversial. Surgical options for these patients are limited. The study was aimed to investigate the validity o...

Background Technical errors are the most common preventable cause of recurrence after high ligation and stripping procedures for the treatment of great saphenous vein incompetence. Ultrasound-assisted varicose vein surgery (UAVS) uses intraoperative ultrasound during high ligation and stripping to minimize such failures, although no data have been reported regarding its use during open surgery. The present study compared the short-term outcomes of UAVS and endovenous laser ablation (EVLA) with a 1470-nm laser. Methods The present prospective randomized study was conducted from January 2019 to December 2019. We compared 40 patients who had undergone UAVS under regional anesthesia with an equal number of patients who had undergone EVLA under tumescent anesthesia. Both groups received 1 week of standardized postoperative analgesia. The improvements in the pain score, venous clinical severity score, and recurrence at 6 months and 1 year were studied. Results No significant differences were found in either clinical or radiologic great saphenous vein recurrence after UAVS compared with EVLA at 1 year. The mean pain score at 8 hours after the procedure was higher in the UAVS group (3.7 ± 1.2 vs 2.9 ± 1.0; P = .03). At 1 week, the score was higher in the EVLA group (1.8 ± 0.7 vs 1.4 ± 0.5; P = .01). At 6 months, the venous clinical severity score had improved from 9.2 ± 3.7 to 2.4 ± 1.4 in the UAVS group and from 9.3 ± 3.2 to 2.1 ± 0.8 in the EVLA group (P = .64). At 1 year, the corresponding scores were 1.3 ± 0.7 and 1.4 ± 0.6 (P = .21). Conclusions UAVS has high technical success, making it a suitable alternative to EVLA using a 1470-nm laser.

Chronic limb-threatening ischemia in the pediatric population is a rare phenomenon. When open repair is necessitated, an autogenous conduit is preferred. However, venous grafts are prone to their own long-term complications. We have presented the case of a 10-year-old boy with chronic limb-threatening ischemia due to popliteal artery thrombosis that was treated with an ipsilateral great saphenous vein bypass. Seven years after the initial procedure, the venous graft had developed aneurysmal degeneration with acute thrombosis, necessitating bypass revision. Through the present case, we have discussed the surgical approach and highlighted the importance of long-term postoperative surveillance after open repair in the pediatric population.

Background Hybrid Deep Venous ARterialisation (DVAR) is offered as a last-ditch attempt for limb salvage in patients with chronic limb threatening ischemia (CLTI). It provides non-selective arterialisation independent of the angiosome, which harnesses the complex venous capillary network bed developed in the leg and foot. Technical Summary We present two elderly men who underwent DVAR to salvage limb with CLTI. DVAR was performed by creating an arteriovenous connection by anastomosis of the great saphenous vein (GSV) at the level of the distal popliteal and proximal tibio-peroneal trunk. Fasciotomy was performed over the length of the GSV. Subsequently, proximal in-situ catheter valvotomies of the GSV valves were undergone with the adjuvant on-table balloon maturation. The distal tarsal veins underwent balloon valvotomy under direct vision with subsequent proximal and distal tarsal veins valvuloplasties. Completion angiogram demonstrated restoration of the flow in the foot and both the patients were relieved of rest pain. Conclusion We successfully performed DVAR in two elderly patients. Our experience shows that DVAR is a simple and safe option that is easily reproducible without the need for complex endovascular hardware, only if a suitable GSV to the foot is available with no history of deep vein thrombosis.

Background. Osteoarthritis (GA) in patients with varicose veins of the lower limbs (VVLL) is more common than in the population, and degenerative changes in the knee joints deteriorate clinical course of such vascular pathology. The purpose and objectives: to assess the effect of GA on the course and efficiency of surgical techniques in VVLL treatment, highlight prognostic criteria. Materials and methods. The study included 302 patients (227 men and 75 women aged 29–72 years old), 16 % of which had previous phlebothrombosis and II, III, IV, V and VI classes of venous insufficiency occurred in 10, 14, 37 16 and 23 %, respectively. 263 patients underwent endovenous laser coagulation, and 39 had the traditional phlebectomy and ligation of perforating veins. Results. GA was diagnosed in 18 % of patients with VVLL, more common in men of older age, and involved the great saphenous vein with gate extension and was combined with arteriosclerosis of the lower limbs vessels, which was accompanied by more severe classes of venous insufficiency, while the clinical laboratory manifestations of varicose veins is influenced by disease stage, changes of meniscal horns, the presence and severity of subchondral sclerosis, osteocystosis, synovitis, Baker’s cysts, intra-articular Shtaydi and Hoff bodies. The effectiveness of the results of surgical treatment in patients with GA was worse, while full vein occlusion in a month after the endovenous laser ablation observed occurred in 2.8 times less cases, the number of complications was 7.3 times more frequent that was defined by subchondral sclerosis, osteousuras, Baker’s cysts and intra-articular Hoff’s bodies. Conclusions. The presence of GA is a risk factor for more severe clinical course in leg varicose veins, a negative prognostic negative factor for surgical treatment of the disease and complications number.

Great saphenous vein (GSV) antireflux procedures have evolved during the past few decades to reduce elevated venous pressure. Untreated reflux in the below knee (BK) GSV (BK-GSV) can lead to persistent venous hypertension and deterioration of the venous circulation. The purpose of the present systematic review was to study the influence of BK-GSV intervention on venous disease progression.A search was conducted, adhering to the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. The PubMed and Embase databases were searched and cross-referenced. Studies were included if they had met the inclusion criterion of BK-GSV disease as a primary or secondary outcome. Two of the authors independently determined the eligibility and extracted the relevant data. RevMan, version 5.3 (Cochrane Training, London, UK), and SPSS (IBM Corp, Armonk, NY) were used for statistical computation.Fifteen studies that had assessed BK-GSV reflux recurrence after ablative intervention were included in our analysis. Of the 15 studies, 6 had assessed patients after above knee (AK) high ligation and stripping (HLS), 7 after AK endovenous laser ablation (AK-EVLA), and 2 after AK- and BK-EVLA (AK+BK EVLA). In total, 525 limbs had undergone HLS, 696 AK-EVLA, and 147 AK+BK EVLA. AK+BK EVLA was associated with significantly lower odds of BK-GSV reflux recurrence compared with AK-EVLA only (odds ratio [OR], 0.1857; 95% confidence interval [CI], 0.076-0.4734; P .0001). Although the odds of recurrent BK-GSV reflux appeared to be greater for patients who had undergone AK-HLS compared with AK+BK HLS, the difference was not statistically significant (OR, 0.62; CI, 0.27-1.43; P = .69). Finally, no statistically significant difference was observed in BK-GSV reflux recurrence between patients receiving AK-EVLA and those receiving AK-HLS (OR, 0.85; 95% CI, 0.52-1.39; P = .31).Axial hydrostatic reflux from the groin to ankle is best controlled with AK+BK-GSV ablation. However, GSV ablation can result in saphenous nerve injury. For C4 to C6 disease, more aggressive treatment of the AK+BK-GSV is justified if the duplex ultrasound findings demonstrate groin to ankle reflux. Thermal ablation of the BK-GSV has a lower incidence of saphenous nerve injury than does BK saphenous stripping. More randomized controlled trials are needed to answer questions involving disease recurrence and the best techniques to mitigate these recurrences.

Objective To determine differences in outcomes among patients undergoing ipsilateral carotid bypass with hostile or normal neck anatomy. Methods Single-center retrospective review of all ipsilateral extracranial carotid bypasses performed between 1998 and 2018. Results Forty-eight patients underwent ipsilateral carotid bypass from the common carotid artery to either the internal carotid artery or carotid bifurcation during the study period. Seven patients were excluded owing to either a lack of follow-up or missing data. The indications for intervention included infected patches, aneurysmal degeneration, symptomatic and asymptomatic stenosis or restenosis, carotid body tumors, neck malignancy, and trauma. In 25 procedures (61%), there was a hostile neck anatomy defined as a prior history of external beam neck irradiation or neck surgery. Among this group, 12 pectoralis muscle flaps were performed for reconstructive coverage. Conduits included polytetrafluorethylene (n = 21), great saphenous vein (n = 9), superficial femoral artery (n = 7) and arterial homograft (n = 4). All superficial femoral artery conduits were used in the hostile neck group (P = .03). The overall mean time of follow-up was 22 months, with all bypasses remaining patent with no significant clinical stenosis. The 30-day ipsilateral stroke and myocardial infarction rates were 4.88% each, all within the hostile neck group, with no 30-day mortalities for the entire cohort. One-third of the muscle flaps were performed in the setting of infected patches (P = .02) with no significant differences in perioperative outcomes with use. The overall median hospital length of stay was significantly increased in patients receiving muscle flap coverage (3.0 vs 7.0 days; P = .04). Conclusions In patients with a complex carotid pathology, ipsilateral carotid bypass is an effective solution for carotid reconstruction. Different conduits should be used depending on the indication. Muscle flap coverage should be considered in hostile settings when primary wound closure is not feasible.

We report a vein surgery procedure for popliteal venous aneurysms (PVAs). A 73-year-old woman with a long, irregularly shaped, PVA and thrombus underwent graft replacement using a manually made triple vein panel graft. Simple bypass grafting with a saphenous vein was unsuitable because of long defects and a size mismatch. We harvested the great saphenous vein from the right thigh, divided it into three segments, anastomosed it side-by-side on the long side, and created a venous panel graft. Good graft patency was confirmed at 4 years postoperatively, and the clinical course was stable without pulmonary embolism recurrence.

The purpose of this study was to compare outcomes (within six months) after short stripping (SS) and endovenous laser obliteration (EVLO) in patients with varicose veins when analyzing ultrasound findings, postoperative complications, level of postoperative pain, clinical manifestations, and duration of rehabilitation after the intervention. Patients with varicose veins of lower extremities and insufficiency of large saphenous vein valves had either EVLO or SS with miniflebectomy. All patients were examined before surgery and then in 5 days, 10 days and in 1, 3 and 6 months after it. The patients also had clinical examination, ultrasound duplex scanning of their lower extremity veins; Venous Clinical Severity Score (VCSS) was also used for the trial. Pain was assessed during the first 10 days after the surgery using a 10-point pain assessment scale. 156 patients (177 lower extremities) were followed-up for 6 months. As the results of our study showed, endovenous laser obliteration and short stripping were equally effective in eliminating the reflux of the great saphenous vein (GSV). After 6 months of follow-up, the reflux along the medial inflow was noted in one case in SS group; partial GSV recanalization was noted in one case in EVLO group in 3 months, in 3 cases – in 6 months. Besides, despite LMH preventive doses one patient from EVLO group had EHIT II deep vein thrombosis. The obtained outcomes have demonstrated that EVLO and SS have similar effectiveness and safety. No difference has been found between these two types of treatment, except more pronounced postoperative pain and bruising in SS group. Performed care was equally safe and effective in eliminating GSV reflux, in relieving symptoms and eliminating varicose veins as well as in improving the quality of life. Long-term outcomes, especially the rate of relapses depending on the type of intervention, are to be investigated in future trials.

Introduction: the relevance of further study of the morphogenesis of changes occurring in the superficial veins of the lower extremities is due to the high prevalence of varicose veins and the lack of answers to many questions of interest to phlebologists.The aim of the study was to study the morphological restructuring of connective tissue elements of the human great saphenous vein wall on the calf in norm, ectasia and development of varicose transformation.Material and methods. The study of morphological restructuring of the great saphenous vein wall on the calf was carried out in 3 comparison groups (norm, ectasia, varicose veins) by light microscopy. In 1th group, the structure of the GSV wall was studied on autopsy material of people who died from various causes at the age of 5 to 80 years. In the 2nd and 3rd groups, fragments of GSV in the calf were taken by biopsy (miniphlebectomy) during the execution of the operations for varicose veins. In order to conduct a quantitative analysis of the nature of structural changes in the connective tissue elements of the GSV wall on the calf, a visual analog scale of morphological changes was developed-Visual Analog Morphology Scale (VAMS), in which a certain number of points (from 1 to 10) corresponded to a certain character of morphological changes. Statistical analysis of the obtained data in groups was performed using the IBM SPSS Statistics software package (USA).Results. The general morphological analysis of histological preparations made it possible to visually identify various variants of changes in connective tissue elements inherent in the inner, middle and outer shells of the GSV wall.Conclusions. Age-related morphological changes in the connective tissue elements in the GSV wall on the calf, over the course of a person’s life, do not have the same character as changes occurring in its wall during the development of its ectasia and varicose transformation.

Background Endovenous laser ablation (EVLA) and foam sclerotherapy are effective and safe treatments for chronic venous disease with great saphenous vein (GSV) reflux. We report our experience combining both strategies as a merged approach to treat GSV incompetence to potentiate both methods' superiority and benefits. We aimed to determine the effectiveness of this treatment strategy. Methods A total of 246 limbs with GSV incompetence (C2-C6) treated with EVLA and foam sclerotherapy between January 2016 and December 2019 were retrospectively analyzed. Outcomes of interest were the International Union of Phlebology (IUP) type of anatomic closure (primary, primary assisted, secondary, and therapeutic failure), identified with ultrasound in the GSV after the procedure. Clinical and ultrasound follow-up was conducted at 2 weeks, 3, 6, and 12 months after intervention. We used the Fisher exact test to determine the significance of the association between the type of anatomic closure and the clinical stage according to the Clinical-Etiology-Anatomy-Pathophysiology classification. Results A total of 67% of the treated limbs were C2-C4 and 33% C5-C6. IUP primary closure was achieved in 229 limbs (93%), IUP primary assisted closure in 10 limbs (4%), IUP secondary closure in 1 limb (0.4%), and therapeutic failure in 6 limbs (2%). A total of 45 limbs (18%) required microthrombectomies of tributary veins due to local induration, 7 (2.8%) developed dyschromia, 4 (1.6%) had type 1 endovenous heat-induced thrombosis, and 1 limb (0.4%) developed deep vein thrombosis, which was successfully treated with anticoagulation. Conclusions Our results demonstrate a high occlusion rate of incompetent GSVs with combined EVLA and foam sclerotherapy with infrequent nonserious complications and one case of subclinical isolated popliteal deep vein thrombosis. Combined therapy effectiveness and safety are comparable with other endovenous treatments for chronic venous disease with GSV reflux. The use of both thermal and chemical ablation combines the benefits of both techniques.

Introduction: The classic intervention for saphenous vein varicosity has been Saphenous femoral junction ligation with stripping. But now endogenous laser ablations are recommended over surgery. Method: This is the retrospective study of 122 patients, conducted for the period of one year in the department of Cardio Thoracic and Vascular Surgery of Bir Hospital, Nepal. Results: Out of 122 cases, 84 were of Endovenous Laser Ablation, 31 cases Ligation and Stripping and 8 cases of sclerotherapy with complete success rate in all group. There was a one case of deep vein injury in Liagtion and Stripping group and one case of skin burn in Endovenous Laser Ablation group, along with other minor injuries. Conclusion: Both group have complete success rate however, hospital stay of patients in Endovenous Laser Ablation group was shorter and reassumed daily activities earlier.

For thymic epithelial tumors, simple contact with adjacent structures does not necessarily mean invasion. The purpose of our study was to develop a simple noninvasive technique for evaluating organ invasion using routine pretreatment computed tomography (CT).This retrospective study analyzed the pathological reports on 95 mediastinal resections performed between January 2003 and June 2020. Using CT images, the length of the interface between the primary tumor and neighboring structures (arch distance; Adist) and maximum tumor diameter (Dmax) was measured, after which Adist/Dmax (A/D) ratios were calculated. Receiver operating characteristic (ROC) curves were used to analyze the Adist and A/D ratios.An Adist cut-off of 37.5 mm best distinguished between invaded and non-invaded mediastinal great veins based on ROC curves. When Adist 37.5 mm was used for diagnosis of invasion of the brachiocephalic vein (BCV) or superior vena cava (SVC), the sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and area under the ROC curve for diagnosis of invasion were 61.9%, 92.5%, 81.25%, 82.2%, 81.97%, and 0.76429, respectively. Moreover, there were significant differences between BCV/SVC Adist 37.5 mm and ≤ 37.5 mm for 10-year relapse-free survival and 10-year overall survival (p 0.01).When diagnosing invasion of the mediastinal great veins based on Adist 37.5 mm, we achieved a higher performance level than the conventional criteria such as irregular interface with an absence of the fat layer. Measurement of Adist is a simple noninvasive technique for evaluating invasion using CT. Key Points • Simple contact between the primary tumor and adjacent structures on CT does not indicate direct invasion. • Using CT images, the length of the interface between the primary tumor and neighboring structures (arch distance; Adist) is a simple noninvasive technique for evaluating invasion. • Adist 37.5 mm can be a supportive tool to identify invaded mediastinal great veins and surgical indications for T3 and T4 invasion by thymic epithelial tumors.

BACKGROUND/OBJECTIVE Behcet disease (BD) is not a single unique entity but a syndrome with different clinical phenotypes that can involve arterial and venous vessels of all sizes. To date, there has been no specific test or serum marker to measure and determine the severity of BD, and diagnosis remains based on clinical findings. This study aimed to assess lower extremity venous wall thickness (VWT) measured by ultrasound and laboratory findings and diagnostic performance in patients with BD. METHODS A total of 106 participants were recruited from the rheumatology department in this single-center, case-control study. Participants meeting the eligibility criteria were divided into healthy controls (n = 52) and BD (n = 54). The VWT values of the common femoral vein, great saphenous vein, and popliteal vein were measured using ultrasonography. Laboratory data were obtained from the electronic registration database. Venous wall thicknesses and laboratory findings in patients with BD and healthy subjects were compared. RESULTS Venous wall thickness of the lower extremity veins was higher in the BD group and higher in those with a history of deep vein thrombosis than in those without. The mean leukocyte, monocyte, erythrocyte sedimentation rate (ESR), C-reactive protein, plateletcrit (PCT), red cell distribution width (RDW), mean platelet volume (MPV) values, and monocyte-to-lymphocyte ratio (MLR) were higher in BD patients than in the control group. There was a correlation among increased VWT, ESR, PCT, MPV, RDW, and MLR. CONCLUSIONS C-reactive protein, ESR, MPV, PCT, MLR, RDW, and VWT can be used to assist in the diagnosis of BD.

Numerous surgical techniques are available to treat patients presenting with varicose veins. A balance is sought between advantages and disadvantages of the available techniques to render them suitable for the treatment of varicose veins depending on the patient’s clinical profile. The abolition of axial venous reflux to reduce ambulatory venous hypertension is the critical factor for successful treatment of varicose veins. Surgical ablation in the form of high ligation of sapheno-femoral junction and stripping of great saphenous vein is more than a century old surgical procedure that is still considered the gold standard in surgery. Various surgical techniques have evolved including elaborate open methods with extensive groin and thigh incisions, sub-fascial ligation of perforators using leg long incisions, endoscopic approach, and the recently developed techniques. The modern surgical approaches are minimally invasive, cosmetically appealing, use local anesthesia, and are performed under the guidance of ultrasonography. These surgeries can often be done as office procedures and demonstrate long-term results and similar hemodynamics in comparison to that of traditional open surgical methods. Although endovenous ablative therapies are preferred by both patients and physicians due to potential advantages such as less pain, short duration of hospital stay, faster recovery, technical ease, and short procedure time, the open surgical techniques still have an essential role and definitive indications in the modern clinical settings.

Background. Type 2 diabetes mellitus (DM2) is a risk factor for arteriosclerosis of the lower extremities, and the relationship with the state of the feet venous vascular territory remains insufficiently studied, the effectiveness of surgical treatment of patients with varicose veins is not defined. Objective: to analyze the clinical course of foot varicose veins and the effectiveness of medical measures on the background of DM2. Materials and methods. The study included 302 patients (227 men and 75 women aged 29–72 years old), 16 % of which had previous phlebothrombosis and the prevalece of II, III, IV, V and VI class of venous insufficiency was 10, 14, 37 16 and 23 %, respectively. 263 patients underwent endovenous laser coagulation, and 39 — the traditional phlebectomy and ligation of perforating veins. Results. Among the examined patients with varicose veins of lower extremities DM2 was diagnosed in 9 % of cases, more often in males and elderly patients on the background of atherosclerosis of the foot vessels (iliac, femoral, tibial, popliteal artery), which was accompanied by more frequent involvement of the great saphenous vein in the process and its gate extension, the prevalence of severe grades of venous insufficiency, significantly worse the results of surgical treatment of varicose veins and greater frequency of complications, despite more frequent using of rivaroxaban and low molecular weight heparins, and the effectiveness of endovenous laser ablation after four weeks of its implementation is inferior to that in the group without DM2, while glycemic index inversely correlated with the surface tension of the venous blood, which has prognostic significance in the context of future medical interventions. Conclusions. The presence of DM2 is a risk factor for more severe feet varicose veins, is a negative predictive factor in the effectiveness of surgical treatment of the disease and the complications number.

The use of cyanoacrylate embolization has increased in interest as a safe, effective, and minimally invasive method to treat symptomatic saphenous reflux. The procedure is generally well tolerated by patients, and complications such as phlebitis are minor and usually self-limiting. Postprocedural infections have been described but occur infrequently and usually in the early postoperative course. In the present case report, we have described a late-onset infective thrombophlebitis of the great saphenous vein after cyanoacrylate embolization, requiring surgical excision of the treated vein.

Thyroglobulin-elevated negative iodine scan (TENIS) syndrome represents a significant diagnostic and therapeutic challenge. Highly sensitive imaging modalities are required to help in the localization of disease, treatment planning, and prognostication. When compared to other imaging modalities, F-18 fluorodeoxyglucose positron-emission tomography–computed tomography has superior sensitivity and specificity in localizing the disease in this subset of patients. Tumor thrombus of thyroid cancer extending into the great vein is a very rare occurrence and management criteria have not been well established yet. We present a case of TENIS syndrome with tumor thrombus in the superior vena cava.

The treatment of choice in patients with ischaemic heart disease is coronary artery bypass grafting. The procedure entails the harvesting of the great saphenous vein through a significant leg incision, which may result in infections and wounding at the incision site. Patients with diabetes mellitus pose a greater risk of developing non-healing wounds, which may significantly affect the patient’s quality of life. The use of anti-inflammatory factors and other chemokines derived from cultured human fibroblasts may represent a useful therapeutic approach for the management of surgical wounds in patients with the greatest probability of being wound healing compromised. This case study describes the treatment of a non-healing surgical tibial wound in a male diabetic patient treated with a preparation of human anti-inflammatory interleukins cytokines, and growth factors. The treatment resulted in swift recovery, significant pain reduction and complete wound closure with minimal scarring.

Background: There are various other collaterals draining into the venous system around the saphenofemoral junction in addition to the great saphenous vein. We aimed to determine the efficiency of prophylactic ablation of tributary veins in long term varicose vein and symptom recurrence. Methods: Two hundred and sixty-three consecutive patients whom underwent radiofrequency ablation therapy for the treatment of superficial venous reflux disease were investigated. There were 129 patients who received isolated great saphenous vein ablation (Group A) where as 134 patients underwent ablation of the other tributary veins in addition to the great saphenous vein (Group B) between June 2015 and January 2017. The tributary superficial veins; refluxing and/or not refluxing, draining into the saphenofemoral junction were selectively catheterized and ablated in Group B. Patients are followed at least 1 year after the procedures regulary and researched for recurrence of varciose veins and symptoms. Results: Gender, mean age, body mass index, diameter of the great saphenous veins, small saphenous vein disease, and grade of deep venous insufficiency did not differ significantly between the two groups. The mean number of tributary veins were similar in both groups (n: 1.9 +/- 0.4 in Group A vs. n: 1.8 +/- 0.7 in Group B) which were detected preoperatively as well as during the procedure. The mean number of ablated tributary venous pathways could be 1.4 +/- 0.6 in Group B. During the follow up period symptoms related with varicose veins recurred in 19 patients in Group A where as in 7 patients in Group B ( P < 0.05). Three of these symptomatic patients in Group B were the ones in whom the tributary pathways could not be catheterized ablated where as 14 patients in Group A were diagnosed with newly refluxing tributary pathways. All the symptomatic patients in both groups were managed medically and/or with additional interventions. Conclusion: The absence of any fascial unsheathing and the parietal weakness are suggestive of a lower resistance of the tributary veins wall, so collapse and size of veins make it more complex to catheterization regarding to great saphenous vein. Ablation of the tributary superficial venous pathways during the treatment of great saphenous vein reflux disease decreased the rate of recurrence of superficial venous reflux disease and patients symtoms in our modest cohort.

Vascular bypass surgery in children differs significantly from adults. It is a rarely performed procedure in the setting of trauma and tumor surgery. Besides technical challenges to reconstruct the small and spastic vessels, another concern in bypass grafting is the adequate limb length growth over time. The primary aim of this study was to assess long-term outcome after pediatric bypass grafting, in a single academic center, focusing on potential effects on limb development. In this retrospective cohort analyses we included all pediatric patients undergoing vascular bypass grafting at our department between 2002 and 2017. All patients ≤ 18 years suffered a traumatic injury or underwent a tumor resection of the lower or upper limb. The youngest female patient was 0.4 years, the youngest male patient was 3.5 years. During the observation period, 33 pediatric patients underwent vascular repair, whereby 15 patients underwent bypass grafting. Median overall follow-up was 4.7 years (IQR ± 9). 8 patients (53%) had a traumatic injury (traumatic surgery group) and 7 patients had a planned orthopedic tumor resection (orthopedic surgery group). In 13/15 (87%) a great saphenous vein (GSV) graft and in 2/15 (13%) a Gore-Tex graft was used for bypassing. Both Gore-Tex grafts showed complete occlusion 12 and 16 years after implantation. No patient died in the early postoperative phase (

Background The objective of this study is to examine factors associated with thrombus extension after early experience with mechanochemical ablation, which combines mechanical damage to the venous endothelium with infusion of a sclerosant. Methods A retrospective review was performed of patients who underwent mechanochemical ablation to treat saphenous vein insufficiency in the thigh including the saphenofemoral junction. Data abstracted included patient demographics, procedural details, and postprocedural outcomes. Thrombus extension was determined by postprocedural duplex ultrasound and classified as flush closure with the femoral vein and any extension of thrombus into the femoral vein. Results Seventy-three patients met inclusion criteria. The mean age of the population was 60, 17.8% were female, and the mean body mass index (BMI) was 30.7. Seven (9.6%) patients who underwent mechanochemical ablation experienced saphenous vein closure flush with the femoral vein. Eleven (15%) patients experience extension of thrombus to less than 50% of the diameter of the femoral vein and one patient experienced complete thrombosis of the femoral vein. There was no significant difference in age, sex, or comprehensive classification system for chronic venous disorders between the group with thrombus extension and the group without, with the exception of BMI. The mean BMI in the group with thrombus extension was 26.8 vs. 32 in the group without (P = 0.02). There was no significant difference between the 2 groups in sclerosant volume used, distance between catheter tip and SFJ, and mean diameter of GSV in the thigh. Conclusions In this cohort, the incidence of thrombus extension into the femoral vein with mechanochemical ablation was high relative to rates of thrombus extension associated with reported rates of thermal ablation. Further investigation with larger cohorts, and standardized reporting is required to characterize the true rate of thrombus extension after mechanochemical ablation and identify maneuvers which may prevent thrombus extension.

Endothermal heat induced thrombosis (EHIT) is a post-procedural entity following endothermal superficial venous ablation that refers to the propagation of thrombus into the adjacent deep vein lumen. It is identified most commonly during the post-procedural surveillance venous duplex ultrasound. EHIT is recognized as a unique post-procedural entity, distinct in clinical behavior from a deep vein thrombosis. The definition, classification systems, pathophysiology, risk factors, treatment, and prevention are all discussed. The understanding of EHIT has advanced considerably, but additional data are required to understand its impact on quality of life and the cost-effectiveness of surveillance.

Background: The most common conduit for coronary artery bypass graft (CABG) surgery is saphenous vein graft (SVG). There are two techniques for SVG harvesting: open and endoscopic. Our aim is to evaluate clinical results of endoscopic versus open SVG harvesting. Nowadays, endoscopic vein harvesting (EVH) has become prevalent because of reduced complications with more patient satisfaction. Objective: We designed and performed a prospective randomized cohort study of patients undergoing CABG to compare the results of open versus endoscopic harvesting technique. Methods: Patients who underwent elective CABG at our hospitals were divided into two groups, during the period of January 2019 to March 2021. The EVH group (50 patients) underwent endoscopic technique compared with the open vein harvesting (OVH) group (50 patients) that was underwent open surgical incision for great saphenous vein (GSV) harvesting. The two groups demographically were similar and received identical management. Leg wound was evaluated at discharge, two weeks, and four weeks for evidence of any complications. Early outcomes were recorded, including infection, gaped wound and surgical re-suture, degree of pain, level of cosmetic satisfaction, and early mobilization. Results: In the EVH group, harvesting time increased, and incision closure time decreased in comparison with OVH. The hospital stay was 5.5 ± 2.4 days in the EVH group versus 9.5 ± 2.7 days in the OVH group. Leg wound complications were significantly reduced in the EVH group in comparison with the OVH group. Conclusions: Endoscopic vein harvesting technique reduced leg wound complications. Conveniently, patients also were cosmetically satisfied.

Background Superficial venous disease of the lower extremity has a significant impact on quality of life. Both truncal and tributary vein reflux contribute to this disease process. Endovenous foam sclerotherapy is a widely used technique throughout the world for the management of superficial venous reflux and ultrasound guidance improves its safety and efficacy. Methods A PubMed search for ultrasound-guided foam sclerotherapy (UGFS) was conducted and all abstracts were reviewed to identify clinical trials and systematic reviews for a full-text analysis. Additional articles were also identified through searching the references of the selected studies. Results The production of foam for sclerotherapy in a 1:3 or 1:4 ratio of air to sclerosant is optimal in a low silicone, low-volume syringe system. Physiologic gas may decrease any side effects, with the trade-off of decreased foam stability. Proper technique with appropriate sterility and cleansing protocols are paramount for safe and effective treatment. The technical success of UGFS for great saphenous vein disease is inferior to endothermal and surgical modalities and retreatment is more common. However, the clinical improvement in patient-reported quality of life is similar between these three modalities. When used for tributary veins in combination with endothermal approaches of the truncal veins, UGFS has high rates of success with excellent patient satisfaction. UGFS has demonstrated an excellent safety profile comparable with or superior to other modalities. Conclusions With proper technique, UGFS is safe and effective for the management of superficial venous disease.

We report the case of a 61-year-old man who had presented with acute unilateral limb swelling. Computed tomography venography and duplex ultrasound demonstrated compression of the right common femoral vein by a common femoral vein adventitial cyst. Before intervention, the patient had developed an acute deep vein thrombosis of the right common femoral vein and great saphenous vein. Preoperative magnetic resonance imaging demonstrated concern for synovial connection. After 6 months of anticoagulation therapy, the patient underwent adventitial cyst excision with ligation of the hip joint articular connection. At 4 months postoperatively, the patient was symptom free without cyst recurrence. The findings from the present case support the synovial theory for adventitial cystic disease.

Background Vascular access (VA)-related high flows (HF) are common with brachial artery based fistulas. Flow-reduction procedures are indicated in symptomatic patients or asymptomatic ones with flows >2L/min. However concomitant issues increase their complexity. We describe a case of a patient suffering congestive heart failure as a result of HF brachial-basilic fistula >3L/min. A simultaneous late basilic vein transposition and revision using distal inflow (RUDI) was performed. Case report/selected technique A large diameter un-transposed arterialized basilic vein was carefully and completely mobilized up to the proximal upper arm. After harvesting an autologous great saphenous vein (GSV) segment, a new inflow anastomosis was performed in the proximal ulnar artery. At the final stage, and after tunneling the mobilizing basilic vein in a subcutaneous semicircular configuration, an end-to-end anastomosis joining the two stumps (basilic vein outflow portion and GSV inflow arterial portion) was performed. A decision-making process in order to reach this complex option is discussed. Access flow and cardiac output were greatly attenuated following our approach. After a mean follow-up of 9 months no VA complications were observed, with flow still detected below 2L/min. All cardiac symptoms and ultrasound investigations improved. Conclusion Multiple VA issues including HF pose a risk for abandonment and a challenge for the vascular surgeon. An effort towards increasing the “upper extremity life span” is advised.

They were followed up at 1 week, 6 months, 1 and 3 years. Clinical outcomes, changes in the Quality of Life (QOL) questionnaires SF-36™, VCSS and AVVQ, evolutive vein occlusion rates were assessed by duplex ultrasound, and ulcer closure was checked.Results: The sample was divided into two groups: (Group 1) GSV diameter ≥ 13.0 mm (median 19.0 [14– 24]), 17 subjects, and (Group 2) GSV diameter ≤ 12.9 mm (median 10.3 [10– 12]), 16 subjects. No major adverse event was observed, and the postoperative minor adverse event rates were similar between the two groups. A significant improvement was observed in VCSS and AVVQ from the preoperative levels to the sixth month and the third-year follow-up. Twelve of 13 ulcers had healed at 1 year and remained closed until 3 years. The entire sample had a significant increase in all short form 36 domains, except for mental health in the Group 2 (GSV ≥ 13.0 mm). Overall first week occlusion rate for the whole sample was 90.9% and 69.7% at the 3-year follow-up. No difference in occlusion rate was observed between the two groups at any time.Conclusion: Exclusively outpatient combined techniques were safe and feasible in this study with no major adverse events, despite the large diameters of the GSV or ulcer presence. Within 3 years, both diameter groups showed equivalent improvement in all QOL parameters, satisfactory axial occlusion, and maintained ulcer closure.Keywords: saphenous vein, varicose veins, varicose ulcer, quality of life, catheter ablation, sclerotherapy

Objective Thrombus extension into the deep venous system following superficial vein chemical ablation with Varithena polidocanol microfoam has been reported. The objective of this study was to assess the effect of intraoperative improved techniques during treatment for patients with symptomatic varicose veins and their impact on extension of thrombus into deep veins. Methods A retrospective review of a prospectively maintained database was performed. All patients who underwent endovenous chemical ablation with polidocanol microfoam (Varithena, Boston Scientific, Marlborough, Mass) for symptomatic superficial axial and tributary vein reflux were identified. Patients had postoperative duplex (48-72 hours) scanning after the procedure; those who did not adhere to the recommended follow-up were excluded. Demographic data, CEAP Classification, Venous Clinical Severity Score, procedure details, and follow-up data were abstracted. Results Between April 2018 and August 2020, 157 limbs in 122 patients were treated with Varithena microfoam; 129 limbs in 99 patients met our inclusion criteria. Veins treated included the great saphenous vein (n = 89), anterior accessory saphenous vein (n = 15), small saphenous vein (n = 14), and tributary veins (n = 56). Adjunctive techniques during treatment included intraoperative elevation of the limb to greater than 45°, ultrasound mapping and digital occlusion of large perforator veins, limitation of foam volume per session, injection of sterile saline before treatment, and compression of the limb in the elevated position. The preoperative Venous Clinical Severity Score was 11.4 and decreased after treatment to 9.7. The immediate closure rate was 95% with 81% overall symptomatic relief at last follow-up. The mean follow-up was 113.5 days for the entire cohort; two limbs (1.5%) required postoperative anticoagulation for thrombus extension into the deep venous system (common femoral vein n = 1; popliteal vein n = 1) postoperatively for a mean of 22 days. Both resolved with anticoagulation. One asymptomatic limb developed a femoral vein deep venous thrombosis and one symptomatic late deep venous thrombosis was noted 4 months after the procedure. Postoperative pain and phlebitis were reported in 15.6% and 14.8% of patients, respectively, and all had resolved at last follow-up. No pulmonary emboli were noted and no neurologic or visual adverse events were recorded. Conclusions Adjunctive techniques during microfoam ablation decreased thrombotic complications in our series compared with those reported in earlier phase III clinical trials. Excellent early closure and symptomatic improvement were also noted. Endovenous microfoam ablation with Varithena is a safe and effective nontumescent, nonthermal alternative to laser and radiofrequency ablation.

血管平滑筋腫は平滑筋を発生母地とする有痛性の良性腫瘍であるが，血管外科領域での報告は稀である．われわれは大伏在静脈（great saphenous vein: GSV）に発症した本疾患を，表在静脈血栓症を合併した静脈性血管瘤と誤認した症例を経験した．症例は63歳男性，主訴は左大腿部の有痛性静脈瘤．静脈エコーにてGSV壁に連続した径14.3 mmの腫瘤を認め，壁在血栓を伴う静脈性血管瘤と診断，外科的切除適応とした．手術当日のエコーで初めて腫瘤が内部充実性，多房性で，カラードプラにて豊富な血流を有することを確認し，壁在血栓ではなくGSVの限局性腫瘍と診断した．手術は局所麻酔下に腫瘍を摘出し，病理組織学的検査でGSVに発生した血管平滑筋腫と診断した．臨床経過上繰り返す疼痛を有し，エコー上静脈壁に連続した充実性腫瘤を確認した場合は，本疾患を考慮しカラードプラ法により腫瘤の性状評価を行うべきである．

Objective: To investigate the optimal duration of compression therapy after endovenous laser ablation (EVLA) using a 1470-nm diode dual-ring radial laser fiber for great saphenous vein (GSV) insufficiency. Methods: Patients undergoing EVLA of GSV for varicose vein disease were divided into two groups based on the duration of subsequent compression after the procedure: short duration group (S group; 0–2 days) and long duration group (L group; 1–4 weeks). Patient-reported outcomes (pain and quality of life [QOL]) were set as the primary outcomes, and objective findings (venous clinical severity score [VCSS], leg circumference, and duplex ultrasound [DUS] findings) were set as the secondary outcomes. A follow-up examination was performed at 1 week and 1 and 6 months. Each variable between the groups was compared after a propensity score matching using the age, sex, Clinical–Etiological–Anatomical–Pathophysiological (CEAP) clinical class, job type, and target variable as covariates. A per-protocol analysis was performed. Results: The S and L groups included 98 and 99 patients, respectively. A propensity score matching analysis showed no significant differences between the groups in any outcomes at any follow-up intervals. Conclusion: Long-term compression showed little benefit; therefore, the prescription of compression stocking beyond 2 days after EVLA is unnecessary.

Objective To evaluate the 6 months efficacy and safety of cyanoacrylate closure for the treatment of incompetent great saphenous veins (GSVs) in comparison with radiofrequency ablation (RFA). Methods In this multicenter, retrospective, clinical trial, 398 symptomatic subjects with incompetent GSVs were assigned to either cyanoacrylate closure or RFA. The primary endpoint, complete closure of the target GSV, was determined using duplex ultrasound examination starting from one-, three-, and six-month visits. Results All patients were followed for 6 months and there was no difference between the groups in terms of mean follow-up time. Hospital stay and return to work/activity were shorter in the cyanoacrylate ablation (CAA) group, and these differences between the groups were statistically significant. Ecchymosis was observed higher in the RFA group and was statistically significant. Conclusions In this study, in which we examined the CAA and RFA methods, we found that both methods were effective and reliable; however, we found that patients in the CAA group had a more comfortable postoperative period and returned to work earlier.

Background: Reducing the leg wound morbidity is crucial for the patients undergoing coronary artery bypass grafting (CABG) with great saphenous vein (SV) grafts harvested by no-touch (NT) technique. This study was to summarize the experience of skin bridging technique for reducing wound morbidity and the influence of it on one-year bypass graft patency. Methods: According to skin bridging or not, harvesting times, graft length, number of bleeding branches, postoperative subjective perception assessment scale (ASEPSIS) scores and one-year patency rate were analyzed. Results: From June 2018 to February 2019, 60 patients underwent CABG with SV grafts either with open-incision NT or skin bridging NT (30 in each group). There were no significant differences in age (71.4 ± 5.1 years vs. 68.9 ± 5.5 years) or graft length (23.3 ± 1.1 cm vs. 23.9 ± 1.3 cm) between the two groups. The bridging/NT group had a significantly longer harvest time (38.5 ± 4.9 min vs. 18.5 ± 2.6 min; P < 0.001) and a significantly greater number of bleeding branches (1.9 ± 1.2 vs. 0.8 ± 0.8; P < 0.001) than the open NT group. The open NT group had a significantly higher ASEPSIS score (23.8 ± 2.0 vs. 15.7 ± 2.6; P < 0.001). There was no significant difference in patency rate at one-year follow-up. Conclusion: Obtaining the SV by the combined NT/discontinuous skin bridging technique is a satisfactory method for patients who underwent CABG. This method has important clinical significance in reducing wound morbidity in the harvest of NT grafts.

Introduction Several treatment modalities have been postulated to improve the efficacy of varicose vein treatment. Addition of glycerine to the sclerosing material has been documented to increase its viscosity and subsequently prolong the duration of stability, in addition to the direct sclerosing effect of glycerine. This histological and immunohistochemical study investigated the efficacy of addition of glycerine 72% to sclerotherapy on the human varicose vein. Methods After surgical stripping of great saphenous veins, three equal segments were resected between two clamps. Specimen 1 was injected with saline only, specimen 2 was exposed to foam sclerosant 2%, and specimen 3 was exposed to a mixture of foam sclerosant 2% and glycerine 72%. All segments were left for 5min. Vein segments were then processed for histological and immunohistochemical study. Results Microscopically, haematoxylin and eosin-stained specimen 1 showed endothelial swelling, cytoplasmic eosinophilia and pyknotic nuclei. The media showed sarcoplasm vacuolisation and necrosis. Specimen 3 showed hypereosinophilic sarcoplasm of the smooth muscle fibres. Oedema was less evident, with a relative decrease in the thickness of the wall compared with specimen 2. Immunohistochemically, the expression of smooth muscle actin was weak in specimen 3 compared with specimens 1 and 2. Expression of CD31 antibody was much reduced in specimen 2 which showed conserved islands of endothelial cells. By contrast, there was a complete loss of endothelial cells in specimen 3. Conclusion Addition of glycerine 72% to foam sclerosant has a more damaging effect on human vein wall.

Introduction: In the current study, we present single surgeon experience of a new radiofrequency ablation system, the catheter, and the device. Patients and Methods: The new system, which comprises a generator and an intervally illuminated radiofrequency ablation catheter, was used for the treatment of 272 consecutive patients with chronic venous insufficiency of the great saphenous vein between November 2017 and October 2018. Mean age of the patients was 53.40 ± 11.91 years. Mean saphenous vein diameter was 8.51 ± 2.45 mm. Bilateral great saphenous vein reflux disease was present in 19% (51 cases) of the patients. At the end of the procedure, the closure of the great saphenous vein was confirmed with Doppler ultrasonography. Results: Procedures could be successfully performed in all, except 1 obese (BMI> 30 kg/m2) male patient. At the 3rd month, outpatient clinic follow-up control Doppler USG revealed successful ablation of the treated great saphenous vein in 260 patients (96%), whereas in 12 cases (4%), there was continuing reflux. The diameters of the saphenous veins in these patients ranged between 6.9 mm and 19.5 (mean: 10.68 ± 3.41) mm. Ten patients could be treated successfully with ablation with the same device controlled both at the interventional section as well as on the 3rd month outpatient clinic follow-up. The remaining patients underwent high ligation of the great saphenous vein. Paresthesia occurred in 1 patient and had been permanent. Hematoma occurred in a male patient and resolved spontaneously. Conclusion: Preliminary results of our new radiofrequency ablation device with illumination guidance for the treatment of great saphenous vein reflux disease indicated successful results with enhanced physician utilization, comfort, and reliability.

Background The day of the week (DOW) for performing procedures and operations has been shown to affect clinical and resource utilization outcomes. Limited published data are available on vascular surgery operations. Our primary objective was to assess outcomes by DOW for infrainguinal lower extremity bypass (LEB) performed for claudication or rest pain. The secondary objective was to assess outcomes by DOW for LEBs performed for tissue loss. Methods The Vascular Quality Initiative was queried from 2003 to 2018 for all elective index infrainguinal LEBs performed for claudication or rest pain. Cases performed for acute limb ischemia as well as concomitant peripheral vascular intervention, nonelective LEBs, sequential grafts, and weekend cases were excluded. LEBs were grouped by DOW: Monday–Tuesday (early weekdays) versus Wednesday–Friday (later weekdays). Baseline data, operative details, and outcomes were collected. Univariate and multivariable analyses were performed. LEBs performed for claudication/rest pain were analyzed together while tissue loss was assessed separately. Results There were 12,084 LEBs identified—44.5% performed on Monday–Tuesday and 55.5% on Wednesday–Friday. Overall, the mean age was 65.6 years, 68.6% were male, and 82.8% were Caucasian. LEBs were performed for claudication in 57.4% of cases. An autogenous great saphenous vein was used in 58.8% of cases, whereas a prosthetic graft was used in 35.1% of cases. The most common bypass origin was the femoral artery (94.1%), and target was the popliteal artery (70.1%). Significant differences between Monday–Tuesday versus Wednesday–Friday, respectively, were mean body mass index (27.8 kg/m2 vs. 28 kg/m2), preoperative aspirin use (74.2% vs. 72.5%), continuous vein harvest technique (41.9% vs. 44%), and mean operative time (mins) (216.2 vs. 222.6) (all P 0.05). However, LEBs performed for tissue loss on Wednesday–Friday versus Monday–Tuesday had similar cardiac complications (P > 0.05). Conclusions Elective LEBs performed on later weekdays for claudication/rest pain were associated with cardiac complications and prolonged LOS, whereas tissue loss confirmed association with prolonged LOS. Further investigations are needed to identify whether increased resources or allocation of resources should be focused on later weekdays to optimize patient outcomes.
