Femoral artery pseudoaneurysm (FAP) is one of the most common vascular complications after cardiac and peripheral angiographic procedures. Ultrasound-guided thrombin injection is the standard procedure for the treatment of FAP. Complications such as thrombotic events with leg ischemia after thrombin leakage into the femoral artery or immunogenic consequences are rare. Our experience indicates the need for caution when treating FAP, as severe complications can occur after thrombin injection in a femoral pseudoaneurysm, leading to a fatal event.
