Abstract

Abstract Background Cardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC) use, especially in transfusion-prone adults undergoing elective cardiac surgery. Methods 192 patients were randomly assigned to restrictive (group A, 100 pts), or liberal (group B, 92 pts) intraoperative intravenous fluid administration. All operations were conducted by the same team (same surgeon and perfusionist). After anesthesia induction, intravenous fluids were turned off in Group A (fluid restriction) patients, who only received fluids if directed by protocol. In contrast, intravenous fluid administration was unrestricted in group B. Transfusion decisions were made by the attending anesthesiologist, based on identical transfusion guidelines for both groups. Results 137 of 192 patients received 289 PRC units in total. Age, sex, weight, height, BMI, BSA, LVEF, CPB duration and surgery duration did not differ between groups. Fluid balance was less positive in Group A. Fewer group A patients (62/100) required transfusion compared to group B (75/92, p < 0.04). Group A patients received fewer PRC units (113) compared to group B (176; p < 0.0001). Intraoperatively, the number of transfused units and transfused patients was lower in group A (31 u in 19 pts vs. 111 u in 62 pts; p < 0.001). Transfusions in ICU did not differ significantly between groups. Transfused patients had higher age, lower weight, height, BSA and preoperative hematocrit, but no difference in BMI or discharge hematocrit. Group B (p < 0.005) and female gender (p < 0.001) were associated with higher transfusion probability. Logistic regression identified group and preoperative hematocrit as significant predictors of transfusion. Conclusions Our data suggest that fluid restriction reduces intraoperative PRC transfusions without significantly increasing postoperative transfusions in cardiac surgery; this effect is more pronounced in transfusion-prone patients. Trial registration NCT00600704, at the United States National Institutes of Health.

Abstract

This online structured survey has demonstrated the global impact of the COVID-19 pandemic on vascular services. The majority of centres have documented marked reductions in operating and services provided to vascular patients. In the months during recovery from the resource restrictions imposed during the pandemic peaks, there will be a significant vascular disease burden awaiting surgeons. One of the most affected specialties.

Abstract

Objective: To document the recovery of vascular services in Europe following the first COVID-19 pandemic peak. Methods: An online structured vascular service survey with repeated data entry between 23 March and 9 August 2020 was carried out. Unit level data were collected using repeated questionnaires addressing modifications to vascular services during the first peak (March – May 2020, “period 1”), and then again between May and June (“period 2”) and June and July 2020 (“period 3”). The duration of each period was similar. From 2 June, as reductions in cases began to be reported, centres were first asked if they were in a region still affected by rising cases, or if they had passed the peak of the first wave. These centres were asked additional questions about adaptations made to their standard pathways to permit elective surgery to resume. Results: The impact of the pandemic continued to be felt well after countries’ first peak was thought to have passed in 2020. Aneurysm screening had not returned to normal in 21.7% of centres. Carotid surgery was still offered on a case by case basis in 33.8% of centres, and only 52.9% of centres had returned to their normal aneurysm threshold for surgery. Half of centres (49.4%) believed their management of lower limb ischaemia continued to be negatively affected by the pandemic. Reduced operating theatre capacity continued in 45.5% of centres. Twenty per cent of responding centres documented a backlog of at least 20 aortic repairs. At least one negative swab and 14 days of isolation were the most common strategies used for permitting safe elective surgery to recommence. Conclusion: Centres reported a broad return of services approaching pre-pandemic “normal” by July 2020. Many introduced protocols to manage peri-operative COVID-19 risk. Backlogs in cases were reported for all major vascular surgeries.

Abstract

Background/Objectives: Device selection during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) remains an important issue for ensuring endograft durability. This study evaluated the early and follow-up outcomes of elective EVAR with the Endurant platform. Methods: A single-center retrospective analysis was conducted including consecutive elective EVAR procedures with the Endurant II/IIs (2008 to 2024) device. Primary outcomes were technical success, mortality and major complications at 30 days. Survival, endoleak I/III and freedom from reintervention were secondary outcomes. Cox proportional hazards models were employed for risk-adjusted follow-up outcomes. Results: In total, 361 patients were included (72.7 ± 7 years; 96% males; mean AAA diameter 62 ± 14 mm); 92% received a bifurcated device, and 89% conformed to the instructions for use. Technical success was 99.7%. Intra-operative adjunctive procedures included 4.4% proximal cuffs and 1.7% endoanchors. The thirty-day mortality rate was 0.6%, and the major complication rate was 4.1%. Survival was 81% (SE 4.8%), 72% (SE 6.4%) and 52% (SE 9.2%) at 4, 6 and 8 years, with aneurysm-related mortality at 1.7%. Freedom from endoleak Ia was 76% (SE 7.3%) at 6 years, freedom from endoleak Ib was 79% (SE 7.4%) at 7 years and freedom from endoleak III was 94% (SE 3.7%) at 5 years. Freedom from reintervention was 71% (SE 6.1%) and 55% (SE 7.9%) at 5 and 7 years, respectively. No device-related co-factor affected long-term outcomes. Conclusions: Endurant II/IIs endograft is a safe and effective EVAR solution with excellent early outcomes and low long-term aneurysm-related mortality. The need for reintervention in the long term affected less than 50% of cases. [ABSTRACT FROM AUTHOR]

Abstract

Background: Endovascular aortic aneurysm repair (EVAR) represents a valid treatment modality for ruptured abdominal aortic aneurysms (rAAAs). This study aimed to present rAAA outcomes treated by EVAR using the Endurant endograft. Methods: A single-center retrospective analysis of consecutive patients treated with standard EVAR (sEVAR) or parallel graft (PG)-EVAR for infra- or juxta/para-renal rAAA using the Endurant endograft (1 January 2008–31 December 2023) was undertaken. The primary outcomes were technical success, mortality, and reintervention. Follow-up outcomes, including survival and freedom from reintervention, were assessed using Kaplan–Meier estimates. Results: Eighty-eight patients were included (87.5% sEVAR and 12.5% PG-EVAR). The mean aneurysm diameter was 73.3 ± 19.3 mm (71.4 ± 22.2 mm sEVAR and 81.7 ± 33.0 mm PG-EVAR). Among 77 patients receiving sEVAR, 26 (33.8%) received an aorto-uni-iliac device. All PG-EVAR patients were managed with bifurcated devices, one receiving a single PG, seven double PGS, and three triple PGs. Technical success was 98.8% (100.0% sEVAR and 90.9% PG-EVAR). The 30-day mortality was 47.2% (50.7% sEVAR and 27.3% PG-EVAR), with nine (10.2%) deaths recorded on the table. The mean time of follow-up was 13 ± 9 months. After excluding 30-day deaths, the estimated survival was 75.5% (standard error (SE) 6.9%) at 24 months. The estimated freedom from reintervention was 89.7% (SE 5.7%) at 24 months. Only one endoleak type Ia event was recorded during follow-up. Conclusions: Endurant showed high technical success rates and low rates of endoleak type Ia events and reinterventions, despite the emergent setting of repair. rAAA is still a highly fatal condition within 30 days, with an acceptable mid-term survival of 30-day survivors at 75.5%.

Abstract

Purpose: Open repair remains the standard of care for aortic arch pathologies. However, endovascular management became an attractive alternative for high-risk patients. This study aimed to assess the outcomes of the available endovascular techniques for aortic arch pathology management. Materials and Methods: A search of the English literature (2000–2022) using PubMed, EMBASE, via Ovid, and CENTRAL databases (February 1, 2022) was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Studies reporting on patients with aortic arch pathologies managed with custom-made devices ([CMDs] fenestrated or branched thoracic endovascular aortic repair [F/BTEVAR]) and non-CMDs (parallel graft or surgeon-modified FTEVAR) were eligible. Studies reporting on hybrid or open repair were excluded. Studies' quality was assessed using the Newcastle-Ottawa Scale. Primary outcomes were technical success, 30 day mortality, and cerebrovascular events (CVEs). Secondary outcomes were re-intervention and mortality during follow-up. Results: Thirty studies (2135 patients) were included. Treatment indications were mainly dissections (652 cases [48.0%, 652/1358]; 90 type A, 506 type B; 364 acute, 163 chronic) and aneurysms (46.9%, 582/1239). Five studies (211 patients) reported on FTEVAR and 10 (388 patients) on BTEVAR. For FTEVAR, technical success rate was 98.3%. Thirty-day mortality was 3.8% and CVE rate was 12.3%. Ten deaths (9.7%) and 19 re-interventions (9%) were recorded during follow-up (24 months). Regarding BTEVAR, technical success rate was 98.7%, and 30 day mortality and CVE rates were 5.4% and 11.0%, respectively. During follow-up (27 months), 64 deaths (18.7%) and 33 re-interventions (9.6%) were recorded. Parallel graft technique was reported in 11 studies (901 patients). Technical success rate was 76.4%. Thirty-day mortality was 3.9% and 32 (4.3%) CVEs were recorded. Thirty-five deaths (4.4%) and 43 re-interventions (5.5%) were reported during follow-up (27 months). Surgeon-modified FTEVAR was described in 5 studies (635 patients). Technical success rate was 91.6%. At 30 days, 15 deaths (2.3%) and 22 CVEs (3.5%) were recorded. During follow-up (19 months), 26 deaths (4.2%) and 21 re-interventions (3.6%) were detected. Conclusions: Endovascular arch repair presented a variable technical success; >95% for F/BTEVAR; ≤90% for non-CMDs. Acceptable 30 day mortality rates were reported. Cerebrovascular event rates ranged up to 10%. These findings, adjacent to the estimated midterm mortality and re-interventions, set the need for further improvement. Clinical Impact: Endovascular arch repair gains popularity as a valuable alternative, especially in patients considered unfit for open repair. According the available literature, any endovascular technique, including custom-made or off-the-shelf solutions, may be applied successfully, with acceptable early mortality. However, the perio-operative cerebrovascular event rate is still an issue, indicating the need for further advancements. [ABSTRACT FROM AUTHOR]

Abstract

Glaucoma is a progressive optic neuropathy and one of the leading causes of irreversible blindness worldwide. Elevated intraocular pressure (IOP) is the major risk factor for the onset and progression of glaucoma. In addition to elevated IOP, impaired intraocular blood flow is also considered to be involved in the pathogenesis of glaucoma. Various techniques have been used to assess ocular blood flow (OBF), including Color Doppler Imaging (CDI), a technique used in ophthalmology in recent decades. This article reviews the role of CDI in both the diagnosis and effective monitoring of glaucoma progression, presenting the protocol for imaging and its advantages, as well as the limitations of its use. Moreover, it analyzes the pathophysiology of glaucoma, focusing on vascular theory and its role in the onset and progression of the disease.

Abstract

Stenosis grade of the carotid arteries has been the primary indicator for risk stratification and surgical treatment of carotid artery disease. Certain characteristics of the carotid plaque render it vulnerable and have been associated with increased plaque rupture rates. Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) have been shown to detect these characteristics to a different degree. The aim of the current study was to report on the detection of vulnerable carotid plaque characteristics by CTA and MRA and their possible association. A systematic review of the medical literature was executed, utilizing PubMed, SCOPUS and CENTRAL databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. The study protocol has been registered to PROSPERO (CRD42022381801). Comparative studies reporting on both CTA and MRA carotid artery studies were included in the analysis. The QUADAS tools were used for risk of bias diagnostic imaging studies. Outcomes included carotid plaque vulnerability characteristics described in CTA and MRA and their association. Five studies, incorporating 377 patients and 695 carotid plaques, were included. Four studies reported on symptomatic status (326 patients, 92.9%). MRA characteristics included intraplaque hemorrhage, plaque ulceration, type VI AHA plaque hallmarks and intra-plaque high-intensity signal. Intraplaque hemorrhage detected in MRA was the most described characteristic and was associated with increased plaque density, increased lumen stenosis, plaque ulceration and increased soft-plaque and hard-plaque thickness. Certain characteristics of vulnerable carotid plaques can be detected in carotid artery CTA imaging studies. Nevertheless, MRA continues to provide more detailed and thorough imaging. Both imaging modalities can be applied for comprehensive carotid artery work-up, each one complementing the other.

Abstract

Background: Extended downstream endovascular management has been applied in acute complicated type B aortic dissection (acTBAD), distally to standard thoracic endovascular aortic repair (TEVAR), using bare metal stents, with or without lamina disruption, using balloon inflation. The aim of this systematic review was to assess technical success, 30-day mortality, and mortality during follow-up in patients with acTBAD managed with the Provisional Extension To Induce Complete Attachment (PETTICOAT) or stent-assisted balloon-induced intimal disruption and relamination (STABILISE) technique. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 statement was followed. A search of the English literature, via Ovid, using MEDLINE, EMBASE, and CENTRAL databases, until 30th August 2022, was executed. Randomized controlled trials and observational studies (published between 2000–2022), with ≥5 patients, reporting on technical success, 30-day mortality and mortality during the available follow-up among patients that underwent PETTICOAT or STABILISE technique for acTBAD were eligible. The Newcastle-Ottawa Scale was applied to assess the risk of bias. Primary outcomes were technical success and 30-day mortality, and secondary outcome was mortality during the available follow-up. Results: Thirteen studies were considered eligible, twelve in the quantitative analysis. In total, 418 patients with acTBAD managed with the PETTICOAT (83%) or STABILISE (17%) technique were included. Technical success ranged between 97–100%, 99% for the PETTICOAT and 100% for the STABILISE sub-cohort. Thirty-day mortality was estimated at 3.7% (12/321), 1.4% for the STABILISE and 4.4% for the PETTICOAT technique. All studies reported the mean available follow-up which was estimated at 20 months (range 3–168 months), 22 months (mean value) for the PETTICOAT and 17 months (mean value) for the STABILISE technique. Twenty-three patients died during follow-up, with an estimated mortality rate at 5.7% for the total cohort. The mortality during follow-up was 0% for the STABILISE and 7.0% for the PETTICOAT approach. Conclusions: Both, the PETTICOAT and STABILISE techniques presented less than 4% perioperative mortality in patients with acTBAD with high technical success rate. The mid-term mortality rate was at 6%. However, the heterogeneity in the available studies’ highlights the need for further prospective studies, including larger volume and longer follow-up.

Abstract

Conical neck may affect endovascular aneurysm repair (EVAR) outcomes. The aim of this study was to present EVAR neck adverse events [endoleak type Ia (ET Ia) and graft migration], in patients with conical neck morphology compared to patients with non-conical necks. An additional analysis of the factors that may affect neck adverse events in patients with conical necks, during the initial post-operative year, was executed.A retrospective analysis of prospectively data was conducted, including patients that underwent elective EVAR, between 2017 and 2019. All patients completed the clinical and imaging follow-up of the initial 12 months. Regarding imaging, all cases underwent computed tomography angiography (CTA), preoperatively, at the 1The cohort included 150 patients; 66 (44%) presented conical neck morphology. No significant difference was detected regarding the pre-operative anatomic characteristics between the conical and non-conical groups. Only distal (15mm) neck diameter was wider in the conical group (p.001). Supra-renal active fixation was used in 63.3% of the total cohort; 59.5% in patients with non-conical necks and 68.2% in patients with conical morphology (p=.275). Graft oversizing was 18.2% and 18.7% in the non-conical and conical group, respectively (p=.248). Oversizing20% was equal between groups [37.8% vs 33.3%% (p=.608) while oversizing ≥30% was more common among patients with conical necks (3.5% vs. 10.6%, p.001, 3.2 OR, 95% CI 0.79, 12.91). Regarding ET Ia and migration, no difference was recorded between the groups. In a sub-analysis among patients with conical necks, a lower graft migration rate was detected among patients with higher oversizing rate (p=.037).EVAR may offer similarly good midterm outcomes in patients with conical and non-conical neck anatomy. An oversizing to the higher suggested rate may be preventive of graft migration during the first post-operative year in necks with conical morphology. Aggressive oversizing (20%) do not offer any benefit regarding the prevention of adverse events among patients with conical necks.
