%X objective: to analyze the frequency and risk factors of carotid stenosis above 70% in patients undergoing abdominal aortic reconstruction. material and method: ninety-four patients who underwent doppler ultrasound preoperative screening for abdominal aortic surgery between january 2000 and january 2003 were analyzed by the vascular surgery unit of the santa casa of s£¿o paulo (faculty of medical sciences). results: sixty-seven (71%) patients were male. of the 94 patients, 42 (44.6%) had aortoiliac occlusive disease and 52 (53.4%) had abdominal aortic aneurysm. the data analysis showed a prevalence of carotid stenosis above 70% in 8.33% of patients with abdominal aortic aneurysms and 13.51% in patients with aortoiliac occlusive disease, a difference without statistical significance (p = 0.5). the previous history of cerebral ischemic symptoms (stroke and transitory ischemic attack) was predictive of the presence of a 70-99% carotid stenosis. other risk factors for atherosclerosis, such as being male, having diabetes, hypertension and smoking history, were not predictive of the presence of a carotid stenosis above 70%. conclusion: the frequency of carotid stenosis above 70% in patients undergoing abdominal aortic surgery is 9.57% and the presence of transitory ischemic attack or stroke in medical history was predictive of stenosis above 70% in this group of patients.
