Abstract
We report a right common iliac artery aneurysm in an 86-year-old man with congestive heart failure (CHF) syndrome resulting from arteriovenous fistula. A computed tomographic scan revealed a right common iliac artery aneurysm measuring 6.6 cm with an arteriovenous fistula and a left internal iliac artery aneurysm measuring 6 cm. He was admitted to our hospital due to CHF. After CHF resolved rapidly by medication, surgery was performed on an elective basis. An arteriovenous fistula with a 3 cm by 1 cm orifice was found between the right common iliac artery and the left common iliac vein. The fistula was directly closed from the inside of the aneurysm. The abdominal aorta and bilateral common iliac arteries were replaced with a Y-shaped prosthetic graft. His postoperative course was uneventful.
