Unusual presentation of more common disease/injury: Huge anastomotic femoral pseudoaneurysm following aorto-bifemoral bypass

摘要

There has been recent concern that the number of patients at risk of femoral artery false aneurysms may be increasing, due to an increase in the number of cardiac and vascular radiological interventional procedures performed each year. Rarely, such pseudoaneurysms can develop around the anastomotic site of a femoral bypass graft.The present report describes the unusual presentation of a huge femoral pseudoaneurysm in a 70-year-old male patient who had an aorto-bifemoral bypass in the past. A surveillance CT angiogram of a previously diagnosed right femoral pseudoaneurysm revealed that it had reached a size of 10×7×cm – a considerable growth when compared to his previous scan. An urgent referral was then made to the vascular surgery team. He subsequently underwent a successful surgical repair of his right femoral pseudoaneurysm. Postoperatively, he had an uneventful recovery except for a mild wound infection, which was treated with intravenous antibiotics.
