OBJECTIVE The aim of the study was to evaluate the safety and efficacy of percutaneous angioplasty and stenting (PAS) in comparison with traditional open surgical (OS) revascularization for the treatment of chronic mesenteric ischemia. METHODS Over a 3.5-year period, 28 patients (32 vessels) underwent PAS (balloon angioplasty alone, 5 [18%] of 28;(More)
PURPOSE The purpose of this study was to report an initial experience with the endovascular repair of descending thoracic aortic aneurysm. Complications and intermediate-term morphologic changes were identified with the intent of altering patient selection and device design. METHODS Endografts were placed into 25 patients at high-risk for conventional(More)
OBJECTIVE Visceral artery aneurysms may be treated by aneurysm exclusion, excision, revascularization, and endovascular techniques. The purpose of this study was to review the outcomes of the management of visceral artery aneurysms with catheter-based techniques. METHODS Between 1997 and 2005, 90 patients were identified with a diagnosis of visceral(More)
BACKGROUND Case and single center reports have documented the feasibility and suggested the effectiveness of endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs), but the role and value of such treatment remain controversial. OBJECTIVE To clarify these we examined a collected experience with use of EVAR for RAAA treatment(More)
The Society for Vascular Surgery® pursued development of clinical practice guidelines for the management of traumatic thoracic aortic injuries with thoracic endovascular aortic repair. In formulating clinical practice guidelines, the Society selected a panel of experts and conducted a systematic review and meta-analysis of the literature. They used the(More)
OBJECTIVE The purpose of this study was to determine the relationship between aneurysm sac size change at 1, 6, 12, and 24 months and a set of 10 independent "predictive" variables by using a general linear model analysis. METHODS In a multicenter trial, 351 patients received the Zenith tri-modular bifurcated endograft. The predictive variables used for(More)
INTRODUCTION Recommended postoperative surveillance after endovascular aneurysm repair (EVAR) includes serial contrast-enhanced CT scans. The cumulative deleterious effect on renal function, radiation exposure, and significant cost of this surveillance regimen are all problematic. However, there are scant data to support modulation of current post-EVAR(More)
PURPOSE To retrospectively review our experience with visceral artery aneurysms (VAAs) treated with percutaneous coil embolization techniques. METHODS Patient records were retrospectively reviewed between 1988 and 1998 for VAA cases treated with catheter-based techniques. Nine patients (5 women; mean age 64 +/- 11 years) with 12 (8 false and 4 true) VAAs(More)
PURPOSE To evaluate the use of a percutaneous mechanical thrombectomy (PMT) catheter (AngioJet) as an initial treatment for acute (<2 weeks) and subacute (2 weeks to 4 months) arterial occlusion of the limbs. MATERIALS AND METHODS A total of 86 (acute, n = 65; subacute, n = 21) patients were available for retrospective analysis, averaging 65 +/- 14 years(More)
PURPOSE This study was undertaken to assess the effect on renal function of open surgery and endovascular abdominal aortic aneurysm (AAA) repair with suprarenal fixation with the Zenith device. METHODS Data for 279 patients with similar preoperative comorbid conditions were prospectively analyzed after AAA repair. One hundred ninety-nine patients(More)
