Objective: Postoperative gastrointestinal hemorrhage (GIH) following mesenteric revascularization when performed either openly (OR) or endovascularly (ER) has been clinically observed but not reported. The aim of the study is to assess the incidence and predictors of GIH in patients undergoing mesenteric revascularization.
Methods: This was a single-center retrospective review of consecutive patients treated with open or endovascular mesenteric revascularization from 2009 to 2019.
Article Synopsis
- The study evaluates the performance of the Human Acellular Vessel (HAV), a new biologic option for arterial reconstructions, compared to the traditional great saphenous vein (GSV) in patients with advanced peripheral arterial disease (PAD).
- Researchers compared outcomes in 34 patients using HAV to 88 historical patients who underwent bypass with GSV, noting demographic similarities but differences in health conditions and clinical stages.
- Results showed that while the HAV group had a shorter operative time, the rates of major amputation-free survival and overall survival were similar between both groups, highlighting the need for further investigation.
Article Synopsis
- The study examined the outcomes of medically managed Type B intramural hematoma (IMH) from 1995 to 2022, focusing on the natural progression and factors influencing it.
- Out of 104 patients, 92 were treated without surgery; results showed a 1-year survival rate of 85.8% and a 5-year rate of 61.9%, with significant differences in intervention rates between groups with isolated IMH and those with aneurysm/dissection.
- Progression occurred in 37.9% of Group 1 (isolated IMH) and more frequently in Group 2, highlighting the importance of monitoring and potential intervention for high-risk patients.
Objective: The aim of this study is to determine perioperative outcomes and the patency of interposition conduits for visceral arterial reconstruction in this setting.
Summary Background Data: Visceral arterial encasement in locally advanced pancreatic cancer was historically a contraindication for surgery. With modern effective neoadjuvant strategies, our recent experience has made advanced vascular resection and reconstruction feasible in selected patients.
Objective: Type II endoleaks (T2ELs) are the most common cause of reintervention after endovascular aneurysm repair (EVAR). Although most resolve spontaneously, the long-term implications of T2ELs remain elusive. We aim to evaluate the impact of persistent and late T2ELs on clinical outcomes after EVAR.

- Patients with chronic limb-threatening ischemia (CLTI) face high amputation risks when they lack a usable great saphenous vein for bypass surgery; the study investigates the use of the Human Acellular Vessel (HAV) to address this.* -
- The HAV is a synthetic vascular conduit made from human cells and a dissolvable scaffold, designed to be nonimmunogenic, and was tested in a clinical study approved by the FDA for patients unable to use their own veins for arterial bypass.* -
- In a trial involving 29 patients with severe CLTI, the HAV achieved 100% technical success in surgeries, resulting in an 86% limb salvage rate, although there was a 7% mortality

Objective: Aortic and iliac graft infections remain complex clinical problems with high mortality and morbidity. Cryopreserved arterial allografts (CAAs) and rifampin-soaked Dacron (RSD) are options for in situ reconstruction. This study aimed to compare the safety and effectiveness of CAA vs RSD in this setting.
View Article and Find Full Text PDFBackground: The longitudinal clinical significance of type II endoleaks (T2ELs) remains controversial. Specifically, the real-world incidence, need for reintervention, and associated mortality referable to T2ELs remain unknown. Moreover, current professional society clinical practice guidelines recommend differing aneurysm sac growth thresholds to prompt intervention.

The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch.
Methods: Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions.
Background: Infected aortic and iliac artery aneurysms are challenging to treat. Cryopreserved arterial allografts (CAAs) or rifampin-soaked Dacron (RSD) are standard options for in situ reconstruction. Our aim was to compare the safety and effectiveness of CAA versus RSD for these complex pathologies.

- The USMLE Step 1 exam has transitioned to a pass/fail format since January 2022 to address concerns about its validity as a screening tool and to support underrepresented in medicine (URiM) candidates, who typically have lower scores than their peers.
- This change aims to improve the educational experience for all students and encourages program directors to focus on a more holistic evaluation of applicants, including personality traits and extracurricular activities.
- The impact on Vascular Surgery Integrated residency programs is uncertain, but directors are likely to rely more heavily on USMLE Step 2 Clinical Knowledge scores and subjective measures like medical school rank as they adapt to this new selection process.
Objective: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset.
Methods: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders.
Objective: Aberrant subclavian arteries (aSCAs), with or without aortic pathology, are uncommon. The purpose of the present study was to review our experience with the surgical management of aSCA.
Methods: We performed a retrospective review of patients who had undergone surgery for an aSCA between 1996 and 2020.
Article Synopsis
- This study aimed to analyze malpractice claims related to aortic pathologies and to explore any changes in litigation rates with the rise of endovascular therapy from 2000 to 2017.* -
- Out of 268 reviewed cases, aortic aneurysms and dissections were the most common issues; results showed a majority of verdicts favored defendants, with litigation being more prevalent in the Midwest and Northeast.* -
- Although overall litigation has decreased, claims related to endovascular procedures are increasing, highlighting the need for physicians to be aware of legal risks as new treatment methods develop.*
Background: Retrograde open mesenteric stenting (ROMS) has become a mainstay in treatment of mesenteric ischemia; however, follow-up in contemporary studies is limited.
Methods: A single-center retrospective review of patients undergoing ROMS from 2007 to 2020 was conducted. Demographics, presentation, and procedural details were reviewed.
Objective: The aim of the present study was to evaluate the presentation trends, intervention, and survival of patients who had been treated for late abdominal aortic aneurysm rupture (LAR) after open repair (OR) or endovascular aortic aneurysm repair (EVAR).
Methods: We reviewed the clinical data from a single-center, retrospective database for patients treated for LAR from 2000 to 2020. The end points were the 30-day mortality, major postoperative complication, and survival.

Objectives: Vascular surgery integrated residency (VSIR) programs are highly competitive; however, criteria for resident selection remain opaque and non-standardized. The already unclear selection criteria will be further impacted by the impending transition of the United States Medical Licensing Examination (USMLE) Step 1 from numeric scores to a binary pass/fail outcome. The purpose of this study was to investigate the historical and anticipated selection criteria of VSIR applicants.
View Article and Find Full Text PDFBackground: Arterial resection (AR) for pancreatic adenocarcinoma is increasingly considered at specialized centers. We aimed to examine the incidence, risk factors, and outcomes of hepatic artery (HA) occlusion after revascularization.
Methods: We included patients undergoing HA resection with interposition graft (IG) or primary end-to-end anastomoses (EE).
Purpose: The aim of the study was to evaluate outcomes after bilateral implantation of the Gore Excluder Iliac Branch Endoprosthesis (IBE) versus those achieved after unilateral implantation.
