AI Article Synopsis
- This review analyzes studies comparing endovascular repair (EVAR) and open surgical repair (OSR) for ruptured abdominal aortic aneurysms (rAAA) to determine which method yields better outcomes.
- Six studies involving 6,731 patients found that EVAR significantly reduced the odds of perioperative mortality, acute kidney injury, and hospital stay compared to OSR, although overall mortality differences were not statistically significant.
- Despite the promising results for EVAR, the quality of evidence was deemed low, indicating a need for cautious interpretation.*
Article Abstract
Background: Optimal management of ruptured abdominal aortic aneurysms (rAAA) has been heavily debated in the literature. The aim of this review is to assess comparative outcomes from propensity-matched studies of endovascular versus open for rAAA.
Methods: Electronic databases (MEDLINE and Embase) were searched in January 2021 using the Healthcare Databases Advanced Search interface. Eligible studies compared endovascular versus open repair for rAAA using propensity-matched cohorts. Pooled estimates of perioperative outcomes were calculated using odds ratio (OR) or mean difference (MD) and 95% confidence interval (CI) using the random-effects model. Time-to-event data meta-analysis was conducted using the inverse-variance method and reported as summary hazard ratio (HR) and associated 95% CI. The quality of evidence was graded using a system developed by the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) working group.
Results: Six studies published between 2010 and 2020 were selected for qualitative and quantitative synthesis, reporting a total of 6731 patients. The odds of perioperative mortality after endovascular aneurysm repair (EVAR) were significantly lower than after open surgical repair (OSR) (OR 0.52, 95% CI 0.41-0.65). The hazard of overall mortality during follow-up was lower, although not significantly, after EVAR than after OSR (HR 0.79, 95% CI 0.62-1.01). The odds of acute kidney injury and early aneurysm-related reintervention were both significantly lower after EVAR than after OSR (OR 0.34, 95% CI 0.14-0.78 and OR 0.57, 95% CI 0.33-0.98, respectively). Patients treated with EVAR stayed in hospital for significantly less time than those treated with OSR (MD -5.13, 95% CI -7.94 to -2.32). The certainty of the body of evidence for perioperative mortality was low and for overall mortality was very low.
Conclusion: The evidence suggests that EVAR confers a significant benefit on perioperative mortality.

To evaluate the incidence of mortality, hemorrhage, and neurological deficits in treating intracranial arteriovenous malformations (AVMs) in patients over 18 through a comparative analysis of surgical approaches and other therapeutic modalities. A systematic review was conducted using MEDLINE, Embase, CENTRAL, and LILACS databases in November 2023. Inclusion criteria included clinical trials, cohorts studies, case-controls studies, and case series comparing patients over 18 undergoing surgery or microsurgery versus other treatments (radiosurgery, isolated embolization, and conservative treatment).

Objective: The integrity of the plantar flap is important for transmetatarsal amputation (TMA) classic closure. However, in ischemic wounds, the plantar flap can be compromised, making the TMA coverage difficult. The aim of this study was to compare the outcomes of rotational vs long plantar flaps for transmetatarsal amputation closure in patients with dysvascular partial foot amputations.

Stanford type B aortic dissection involving the left subclavian artery (LSA) poses significant clinical challenges. The Castor single-branch stent graft and in situ fenestration are commonly used techniques, but the better endovascular treatment remains debated. This study evaluates the clinical effects of the Castor single-branched stent graft versus in situ fenestration in treating Stanford type B aortic dissection involving the LSA.

Background And Purpose: The safety and effectiveness of endovascular techniques in elderly patients with large vessel occlusion (LVO) remain controversial. We investigated the angiographic and clinical outcomes of nonagenarians treated with different endovascular techniques using a balloon guide catheter (BGC), distal aspiration catheter (DAC), and/or stent retriever (SR).
Methods: We analyzed the data from the Registry of Combined versus Single Thrombectomy Techniques (ROSSETTI) of consecutive nonagenarian patients with anterior circulation LVO and compared the outcomes of those treated with BGC+noDAC+SR (101-group), BGC+DAC+SR (111-group), and noBGC+DAC+SR (011-group).

Arteriovenous grafts (AVG) can be the only bailout solution for patients who require kidney replacement therapy but are unsuitable for arteriovenous fistula (AVF) creation. Currently, high-level evidence on the effectiveness and safety of antithrombotic therapy in AVG patients is scarce. Following the PICO (patient; intervention; comparator; outcome) model and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a data search of the English literature in PubMed, SCOPUS, Central Cochrane was conducted, until March 1st, 2023 (PROSPERO Protocol Number: CRD42023401785).
