Abstract
A 71-year-old male with severe paresis due to old cerebral infarction was admitted with the complaint of a large pulsatile mass in the lower abdomen. CT and echogram showed the mass as bilateral isolated iliac artery aneurysm. At the operation, it was proven that this aneurysm was located in the bilarteral common iliac artery and the left internal iliac artery, and that its maximum diameter was 4cm in the right common iliac artery and 7cm in the left.
Exclusion of the aneurysm with Y-dacron graft interposition was performed because resection of the aneurysm was difficult.
The postoperative course was uneventful. Postoperative CT revealed thrombotic occlusion of the excluded aneurysm.
The rate of rupture of these aneurysms is high, as an average of 40 to 60%, and the mortality connected with the ruptured aneurysms is also high. Therefore, patients with this disease should be submitted to surgical repair of the aneurysm when diagnosed.
