title: Anterior tibial artery pseudoaneurysm in a patient with hemophilia: a complication of ankle arthroscopy.
abstract: Arterial pseudoaneurysm formation as a complication of ankle arthroscopy is extremely rare. We present a case of anterior tibial artery pseudoaneurysm identified 10 days after ankle arthroscopy in a patient with hemophilia. The diagnosis was confirmed with a duplex ultrasound scan. The patient was referred to the vascular surgeon and underwent evacuation of the hematoma, resection of the damaged segment of the artery, and reconstruction with a reversed long saphenous vein interposition graft. The patient had an uneventful recovery after the second surgery. The prevention of this complication in patients with hemophilia is discussed, as well as diagnosis and management. Preventative measures include careful dissection while making the portals, preoperative mapping of the artery with a duplex or a handheld Doppler in patients with coagulopathy, and performance of open rather than arthroscopic surgery to excise large osteophytes.
