Background: Endovascular aneurysm repair (EVAR) has become increasingly prevalent for treating asymptomatic abdominal aortic aneurysms (AAA). This study compares the early and late outcomes between EVAR and open aneurysm repair (OAR) in asymptomatic AAA patients.

Methods: A retrospective observational cohort study was conducted involving 564 patients (445 EVAR, 119 OAR) who underwent AAA repair from January 2010 to June 2022.

A 10-Year Retrospective Comparison of Endovascular and Open Aneurysm Repair for Infective Native Abdominal Aortic Aneurysm.

Background: This study compared outcomes of endovascular (EVAR) and open aneurysm repair (OAR) in patients with infective native abdominal aortic aneurysms (INAAAs), evaluating perioperative and in-hospital mortality, antibiotic treatment duration, complications, overall survival rates, and reintervention-free times at 10 years.

Methods: A retrospective cohort study of 125 INAAA patients (80 EVAR, 45 OAR) diagnosed between January 2004 and December 2019 was conducted. Patients were categorized as fit or unfit for open surgery based on cardiac, respiratory, and renal status, following the guidelines established in the EVAR-1 and EVAR-2 trials.

Method: This retrospective chart/image review included all types of arterial bypass procedures performed for suprainguinal arterial occlusion during January 2004 to December 2017.

Navigating Challenges in the Endovascular Treatment of Asymptomatic Aortoiliac Aneurysms: A 10-Year Comparative Analysis.

Background: Treating an abdominal aortoiliac aneurysm (AAIA) with endovascular methods can be challenging when the internal iliac artery (IIA) is involved. Embolizing the IIA and extending the limb to the external iliac artery (IIAE + EE) to prevent a type 2 endoleak may lead to pelvic ischemic complications. To avoid these complications, strategies that preserve the IIA, such as the bell-bottom technique (BBT) and the iliac branch device (IBD), have been proposed.

Prevalence and predictors of combined >50% iliocaval venous obstruction and superficial venous reflux in chronic venous insufficiency patients with healed or active venous leg ulcer.

Objective: The aim of the present study was to investigate the prevalence and predictors of combined >50% iliocaval venous obstruction (ICVO) and superficial venous reflux (SVR) in patients with chronic venous insufficiency (CVI) with a healed (C5) or an active (C6) venous leg ulcer (VLU).

Methods: We conducted a retrospective review of prospectively collected data from patients with CVI with CEAP (Clinical, Etiology, Anatomy, Pathophysiology) class C5 (healed ulcer) or C6 (active ulcer) with SVR who had been treated at our institution from February 2017 to January 2018. The demographic, clinical, and surgical data and duplex ultrasound and computed tomography venography findings were collected.

Early and Late Outcomes of Endovascular Aneurysm Repair for Infected Abdominal Aortic and/or Iliac Aneurysms.

In the past decade, the condition has increasingly been treated with endovascular aneurysm repair (EVAR). However, early and late outcomes, including the continued need for antibiotic treatments and predictors of persistent infection, are poorly understood.

Early and late outcomes of endovascular aneurysm repair to treat abdominal aortic aneurysm compared between severe and non-severe infrarenal neck angulation.

Background: Abdominal aortic aneurysm with severe infrarenal neck angle (>60°) has long been thought to be an obstacle to endovascular aneurysm repair. However, some previous studies reported endovascular aneurysm repair to be safe and efficacious for treating abdominal aortic aneurysm in patients with severe neck angulation. The aim of this study was to investigate the early and late outcomes of endovascular aneurysm repair to treat abdominal aortic aneurysm compared between patients with severe and non-severe infrarenal neck angulation.

Outcomes of Open Repair, Fenestrated Stent Grafting, and Chimney Grafting in Juxtarenal Abdominal Aortic Aneurysm: Is It Time for a Randomized Trial?

Background: The well-established, gold standard treatment for juxtarenal abdominal aortic aneurysms (JAAAs) is open repair (OR). However, endovascular treatment with fenestrated or chimney grafts has been increasingly performed in the past decade. This study compared the outcomes of OR with 2 endovascular methods in JAAA.

Conical neck is strongly associated with proximal failure in standard endovascular aneurysm repair.

Objective: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions.
