A Case of Bilateral Isolated Arteriosclerotic Deep Femoral Artery Aneurysm Discovered after Rupture

Abstract

A 76-year-old man developed pain and swelling in his left thigh. The next day he was admitted to our hospital and computed tomography scan revealed aneurysms of bilateral deep femoral arteries, and the left-sided aneurysm was ruptured. Emergency operation was performed. The distal artery of the aneurysm could not be exposed because of intramuscular hematoma, so we ligated the deep femoral artery. The patient complained of leg swelling after the operation. Twenty days after the first operation, graft replacement of the right deep femoral artery aneurysm using a 6-mm expanded polytetrafluoroethylene prosthetic graft was performed. The postoperative course was uneventful and he was discharged 13 days after the second operation withour leg swelling.
