Objective: Endovascular aneurysm repair (EVAR) is considered the standard therapy for most patients with abdominal aortic aneurysm (AAA). Endoleak is a well-known EVAR-related complication that requires long-term follow-up. However, patient follow-up is often challenging outside clinical trials. We sought to evaluate the incidence and the effect of delayed endoleaks in a Veterans Administration (VA) health care system where long-term follow-up is ensured.
Background: This study analyzed predictors and the long-term consequence of type II endoleak in a large series of elective endovascular abdominal aneurysm repairs (EVARs).
Objective: Restenosis following endovascular treatment of the femoropopliteal segment is associated with the inflammatory response produced in the artery wall at the time of the procedure. Although local drug delivery to the superficial femoral and popliteal arteries promises improved patency, data are currently limited. We hypothesized that improved percutaneous delivery of an anti-inflammatory compound into the adventitia of the femoropopliteal at the time of endovascular treatment would be safe, feasible, and decrease the inflammatory response.
Objective: Type II endoleak is usually a benign finding after endovascular abdominal aortic aneurysm repair (EVAR). In some patients, however, type II endoleak leads to aneurysm sac expansion and the need for further intervention. We examined which factors, in particular the components of metabolic syndrome (MetS), would lead to an increase risk of endoleak after EVAR.
Purpose: We describe the anatomic characteristics on preoperative CT angiography (CTA) that predispose to type-2 endoleaks after endovascular aneurysm repair (EVAR) for an abdominal aortic aneurysms (AAA).
Purpose: To assess the clinical outcomes of internal iliac artery (IIA) embolization before endovascular aneurysm repair (EVAR).
Purpose: This study was designed to analyze the outcomes of endovascular treatment for internal iliac artery aneurysm (IIAA) at mid-term follow-up.
Purpose: To report the first experience using the chimney technique in combination with the latest-generation low-profile stent-graft to seal abdominal aortic aneurysms having a very short neck (proximal sealing zone) and difficult access due to very small iliac vessels.
Purpose: To test the hypothesis that type II endoleak cavity volume (ECV) and endoleak cavity diameter (ECD) measurements are accurate indicators of aneurysm sac volume (ASV) enlargement in patients who undergo endovascular aneurysm repair (EVAR) in the abdominal aorta.
Objective: Endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is increasingly used for emergent treatment of ruptured AAA (rAAA). We sought to compare the perioperative and long-term mortality, procedure-related complications, and rates of reintervention of EVAR vs open aortic repair of rAAA in Medicare beneficiaries.
Objective: Despite improved short-term outcomes, concerns remain regarding durability of thoracic endovascular aortic repair (TEVAR). The purpose of this analysis was to evaluate the pathology-specific incidence of secondary aortic interventions (SAI) after TEVAR and their impact on survival.
Objective: Fenestrated stent grafting has become increasingly popular as a means to manage complex aortic pathology, including juxta- and pararenal aneurysms. The design of a recently developed custom-made fenestrated stent graft, in theory, confers advantages when managing anatomically challenging aortic morphology. This study evaluated its feasibility in anatomically challenging scenarios.
Objective: To evaluate outcomes of open (OR) and endovascular repair (II-EVAR) of internal iliac artery aneurysms (IIAAs) with or without preservation of internal iliac artery (IIA) flow.
Objective: Repair is indicated of asymptomatic popliteal artery aneurysms (aPAAs) that are >2 cm. Endovascular PAA repair with covered stents (stenting) is increasingly used. It is, however, unclear when an endovascular approach is preferred to traditional open repair with great saphenous vein bypass (GSVB). The goal of this study was to assess the treatment options for aPAAs using decision analysis.
Objective: This retrospective nonrandomized study investigated the outcomes of endovascular therapy for long-segment atherosclerotic aortoiliac occlusion.
