Abstract
Pseudoaneurysms of the common femoral artery are typically caused by endovascular interventions or surgical procedures. In contrast, femoral artery pseudoaneurysms due to blunt trauma are rare. We report here a pseudoaneurysm of the common femoral artery diagnosed incidentally 10 years after the blunt inguinal trauma. A 65-year-old man consulted our hospital for his abdominal discomfort. He had no history of diabetes mellitus, coronary artery or cerebrovascular disease. Computed tomography of the abdomen revealed a pseudoaneurysm of the left common femoral artery measuring 50 mm in diameter with massive intramural thrombus. No other associated aneurysms were found. He had experienced an event of blunt left inguinal trauma followed by hematoma formation with subsequent swelling and pain approximately 10 years before. Although he had not gone to hospital for treatment, the hematoma had disappeared gradually. At this presentation, he had no symptoms related to venous or nervous compression and no clinical signs of distal emboli. To avoid rupture or limb ischemia, operation was performed under general anesthesia. The pseudoaneurysm was treated successfully with graft replacement with a 10 mm knitted Dacron graft. The postoperative course was uneventful.
