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)
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)
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)
The Society for Vascular Surgery pursued development of clinical practice guidelines for the management of the left subclavian artery with thoracic endovascular aortic repair (TEVAR). 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)
BACKGROUND Endovascular repair of thoracic aneurysm has demonstrated low risks of mortality and spinal cord ischemia (SCI), but few large series have been published on endovascular thoracoabdominal aneurysm repair, and reports suffer from a lack of accurate comparison with similar open surgical procedures. METHODS AND RESULTS A consecutive cohort of(More)
BACKGROUND The elephant trunk procedure is used for extensive aortic aneurysms. We evaluated its safety, newer indications, and influence of second-stage completion on survival. METHODS Records were reviewed for 94 consecutive patients (age 67 +/- 11 years, 47% men) who underwent the procedure between November 1990 and February 2003. The trunk was(More)
PURPOSE This prospective study was designed to assess the technical success and outcome after patients with thoracic aortic pathology at high risk for conventional therapy were treated with the Zenith TX1 and TX2 endovascular graft. METHODS Between 2001 and 2004, patients at high risk for conventional surgical therapy presenting with chronic aortic(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)
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)
