Vascular Prosthesis Implantation for Treatment of Isolated Iliac Artery Aneurysm a 33-case Report

A total of 33 patients with isolated iliac artery aneurysms, 19 males and 14 females, who received treatment between January 1997 and June 2007, were retrospectively analyzed. Among these patients, 29 suffered from unilateral iliac artery aneurysm and 4 from bilateral iliac artery aneurysm. Under general anesthesia, all patients were subjected to aneurysmectomy, followed by vascular prosthesis implantation for vascular reconstruction. Results revealed that among 4 cases of bilateral iliac artery aneurysm, there was 1 case who was subjected to aorta-bilateral femoral artery vascular prosthesis implantation, and there were 3 cases who underwent aorta-bilateral iliac artery vascular prosthesis implantation; among 29 cases of unilateral iliac artery aneurysm, there was 1 case receiving aorta-common iliac artery vascular prosthesis implantation, 3 cases undergoing iliac-femoral artery vascular prosthesis implantation, 21 cases subjected to common-external iliac artery vascular prosthesis implantation, and 4 cases undertaking common -common iliac artery bypass. Color Doppler ultrasonic examination, spiral CT angiography, or digital subtraction arteriography was performed 3,6 months, 1,3,5,8,and 10 years after surgery. The mean follow-up time was 5 years. Three cases died of acute cerebral infarction, myocardial infarction, and traffic accident 3,6, and 2 years after surgery, respectively. The remaining cases well survived as determined by no recurred iliac artery aneurysm, anastomotic stoma stenosis or lower limb ischemia found. These results indicated that aneurysmectomy and subsequent vascular prosthesis implantation remained a good and primary means for treatment of isolated iliac artery aneurysm under the present medical condition.
