A 46-year-old woman was admitted to Yoichi Hospital for a midshaft fracture of the left femur following a ski injury. Four days after the injury osteosynthesis with intramedullary nails was performed. On the 18th postoperative day, a painful and pulsatile tumor was observed in the medial aspect of the left thigh. A left femoral arteriogram showed a 6 cm large aneurysm of the superficial femoral artery. The aneurysm was excised with a short segment of the vessel and the arterial continuity was restored by an end-to-end anastomosis. The postoperative course was uneventful and she has no symptom of left lower limb ischemia for 3 years. False aneurysm which has been recognized as a late complication of fracture of the femur usually occurs in the deep femoral artery. There are few reports concerning the combination of midshaft fracture of the femur and false aneurysm of the superficial femoral aretry. We describe this case and discuss this rare complication which should be kept in mind when displacement of bone fragment is large enough and close to the artery.
