OBJECTIVES Few centers have adopted endovascular therapy for the treatment of acute mesenteric ischemia (AMI). We sought to evaluate the effect of endovascular therapy on outcomes for the treatment of AMI. METHODS A single-center, retrospective cohort review was performed on all consecutive patients with thrombotic or embolic AMI presenting between 1999(More)
The presence of an aberrant right subclavian artery arising from the proximal descending aorta is a relatively common anomaly of the aortic arch. These vessels may be involved in aortic dissections, either as the site of the primary intimal tear or as a dissected aortic branch, subject to flow limitation and future aneurysmal degeneration. In this report,(More)
OBJECTIVES To evaluate the use of intraoperative guidance by means of C-arm cone-beam computed tomography (CT) (cone-beam computed tomography [CBCT]) and the use of postoperative CBCT to assess for successful aneurysm exclusion in fenestrated branched endovascular aneurysm repair (FEVAR). METHODS Patients with FEVAR who underwent CBCT were retrospectively(More)
PURPOSE Percutaneous angioplasty and stenting (PTAS) is emerging as a therapeutic option for patients with chronic mesenteric ischemia. This study evaluated patency and mortality, and their relationship between degree of vessel occlusion (stenotic or totally occluded), stent characteristics, and comorbidities in patients who were treated with PTAS of the(More)
OBJECTIVE Angiography remains a critical component for diagnostic imaging and therapeutic intervention in peripheral arterial disease (PAD). The goal of this study was to compare angiography with corresponding intravascular ultrasound (IVUS) imaging of the same vessels in patients with PAD. METHODS From 2004 to 2008, 93 patients undergoing angiography for(More)
PURPOSE Endovascular management of thoracoabdominal aneurysms has been studied since 2001, with marked advances allowing for the treatment of complex anatomic situations including chronic aortic dissections, tortuous anatomy, and extensive aneurysms that involve the visceral segment, aortic arch, and iliacs as well. However, the technology is not widely(More)
BACKGROUND Endovascular repair of complex aortic aneurysms (CAAs) can be performed in high-risk individuals, yet is still associated with significant morbidity, including spinal cord ischemia, cardiac complications, and death. This analysis was undertaken to better define the cardiac risk for CAA. METHODS A prospective database of patients undergoing(More)
OBJECTIVES The frequency of late removal of endovascular abdominal aortic repair (EVAR) parallels the rise of endovascular aortic repair. Evaluation of outcomes for EVAR explants may identify risks for complications and alter clinical management. METHODS A patient database was used to identify EVAR patients requiring explant >1 month after implant. A(More)
Popliteal artery aneurysms rarely rupture. We treated a 91-year-old man who presented with a deep venous thrombosis and anemia; rupture of a popliteal artery aneurysm was suspected only after compartment syndrome isolated to the thigh developed as the result of bleeding. Although fasciotomy was required on the basis of the clinical examination alone, the(More)
OBJECTIVE Spinal cord ischemia (SCI) is a devastating complication associated with aortic aneurysm repair. The aim of the current study was to evaluate factors affecting outcomes from SCI associated with endovascular aortic aneurysm repair. METHODS A total of 1251 patients underwent endovascular repair of aortic aneurysm as part of a device trial between(More)
