PURPOSE To retrospectively determine if arterial phase computed tomographic (CT) imaging is necessary for follow-up imaging of patients who have undergone endovascular stent-graft therapy for abdominal aortic aneurysm. MATERIALS AND METHODS This HIPAA-compliant study was exempt from institutional review board approval; informed patient consent was waived.(More)
Endovascular intervention can provide an alternative method of treatment for visceral artery aneurysms. We conducted a retrospective review of all patients with visceral artery aneurysms at a single university medical center from 1990 to 2003, focusing on the outcome of endovascular therapy. Sixty-five patients with visceral artery aneurysms were(More)
A 43-year-old woman presented with symptomatic mesenteric ischemia caused by median arcuate ligament compression of her celiac artery. Magnetic resonance angiography clearly demonstrated stenosis of the proximal celiac artery. She underwent laparoscopic decompression by division of the ligament and excision of the celiac plexus. Laparoscopic Doppler(More)
BACKGROUND Spontaneous dissection of the superior mesenteric artery (SMA) is exceedingly rare. Treatment options range from observation to anticoagulation to open surgery or endovascular repair. We present our experience to date in the management of isolated SMA dissections. METHODS A retrospective review of the vascular surgery and radiology databases(More)
Cystic adventitial disease (CAD) is a well described disease entity that commonly affects the popliteal artery, presenting as a rare cause of non-atherosclerotic claudication. The traditional surgical approaches are cyst resection and bypass, or cyst evacuation or aspiration. We report the case of a 58-year-old female with CAD of the popliteal artery(More)
OBJECTIVES Vascular malformations of the pelvis are rare and present a difficult therapeutic challenge. Surgical treatment is notoriously difficult and carries a high likelihood of recurrence. Surgical proximal ligation of a feeding vessel may in fact be contraindicated, because it can make subsequent transcatheter therapy impossible. The purpose of this(More)
PURPOSE To retrospectively determine the natural history of type II endoleaks detected at thin-section multi-detector row computed tomographic (CT) angiography. MATERIALS AND METHODS Neither institutional review board approval nor patient informed consent was required. Between December 1999 and December 2000, 83 patients (73 men and 10 women; mean age, 61(More)
OBJECTIVE Matrix metalloproteinase (MMP) activity is essential for remodeling of ischemic tissue. The murine hindlimb ischemia model exhibits tissue remodeling including revascularization in part due to angiogenesis. MMP-2 and -9 are type IV collagenases necessary for basement membrane degradation as a part of extracellular matrix remodeling and(More)
PURPOSE Although it has been widely accepted as the evidence supporting prophylactic carotid endarterectomy, aspects of the Asymptomatic Carotid Atherosclerosis Study have left unease among clinicians who must decide which individuals without symptoms should undergo surgery. Additional confusion has been created by the fact that the several large randomized(More)
OBJECTIVE The purpose of this study was to present the experience with aneurysm rupture after deployment of Guidant/EVT (Guidant) endografts and review previously reported cases with other devices. METHODS Records from Guidant/EVT clinical trials and postmarket approval databases from February 1993 to August 2000 were analyzed to identify patients with(More)
