Acute thrombosis of abdominal aortic aneurysms--report of two cases and review of the literature.

An acutely thrombosed abdominal aortic aneurysm (AAA) is a rare but devastating complication of aortic aneurysms. Incidence in reported series is approximately 0.7-2.

Bovine pericardium vs dacron for patch angioplasty after carotid endarterectomy: a prospective randomized study.

Hypothesis: Bovine pericardium (BP) demonstrates improved intraoperative hemostasis and equivalent perioperative morbidity compared with Dacron when used as patch material for angioplasty following carotid endarterectomy.

Objective: To prospectively compare BP and Dacron patch angioplasty after carotid endarterectomy in a randomized fashion.

Methods: Ninety-five consecutive primary carotid endarterectomies were performed in a prospective randomized fashion in 92 patients.

Factors that predict site of outflow target artery anastomosis in infrainguinal revascularization.

Introduction: Lower extremity revascularization is indicated for limb salvage and incapacitating leg claudication. Many risk factors (age, hypertension, diabetes, tobacco use, dyslipidemia, etc) have been associated with atherosclerosis and the development of peripheral arterial occlusive disease. However, whether these risk factors or the surgical indication (claudication or limb salvage) influences the extent and location of infrainguinal disease and hence the target artery (distal anastomosis) is unclear.
