A CASE OF OCCLUSION OF AN ABDOMINAL AORTIC ANEURYSM

Abstract

A 75-year-old man complaining of intermittent claudication was found to have an abdominal aortic aneurysm by magnetic resonance imaging scan at another hospital, and was referred to the hospital for further exploration. Abdominal CT scan showed an abdominal aortic aneurysm 5.5cm in the maximum diameter, extending from a portion under the renal artery to bilateral iliac arteries. In addition the right common iliac artery, internal and external iliac arteries were occluded and a stenosis of the left external iliac artery was also present. Aortography which was performed when coronary arteriography was done also present. Aortography which was performed when coronary arteriography was done about one month after the abdominal CT scan revealed that the abdominal aortic aneurysm under the bifurcation of the renal artery was completely occluded, and the bilateral common femoral arteries were visualized via collateral circulation. From these examinations, abdominal aortic aneurysm associated with thromboembolism was diagnosed, and replacement with a Y-shaped artificial vessel was performed. The postoperative course was mostly uneventful, and the patient was discharged from the hospital on the 16^th postoperative day.
