Abstract
A 79-year-old man had a ruptured atherosclerotic aneurysm of the left circumflex femoral artery or deep femoral artery. The left superficial femoral artery was occluded. If aneurysmectomy and suture closure were to be performed, the left deep femoral artery might be stenotic. So we performed artificial patch plasty after aneurysmectomy to maintain the collateral blood source of the left lower limb. Five years after the initial operation, he was re-admitted for pseudoaneurysm in the left groin area. After resection of the aneurysm, graft interposition was successfully performed. Aneurysms of the medial circumflex femoral artery are very rare. They are mainly caused by osteotome injury and retractor trauma during hip surgery.
