Surgical Treatment of Isolated Iliac Aneurysm. A Report of Three Cases / 日本心臓血管外科学会雑誌

ABSTRACT

Three cases of isolated iliac aneurysms were reported. The first case was a 28-year-old man who was transferred to our hospital in shock. The ruptured left iliac aneurysm was replaced with a prosthetic graft. It was assumed to be a rupture of a false aneurysm. The second case was a 60-year-old man who complained swelling of his right leg and dyspnea on exertion. Angiography revealed tht those symptoms were due to right iliac aneurysm with AV fistula. The aneurysm was replaced with a bifurcating graft and the AV fistula was closed concurrently. The third case was a 55-year-old man who had no symptoms. He had been followed up for hepatitis type C with periodical echogram. The echogram showed dilatation of his bilateral iliac arteries. On a diagnosis of bilateral iliac aneurysms, bifurcating graft replacement was performed. All of these three cases recovered successfully and were discharged. Because the greater part of the cases of isolated iliac aneurysms have few symptoms, many cases were first diagnosed through the event of its rupture. The number of cases of isolated iliac aneurysm with no symptoms will increase with advanced availability of abdominal echogram and CT scanning.
