US-guided Thrombin Injection for Peroneal Artery Pseudoaneurysm after Femoro-peroneal Bypass

Abstract

We report the use of ultrasound-guided thrombin injection (UGTI) in the treatment of peroneal artery pseudoaneurysm after femoro-peroneal bypass. The patient was an 86-years-old woman who was performed femoro-peroneal bypass for her right critical limb ischemia. One and a half years later, her right lower leg developed swelling. The ultrasonography revealed peroneal artery pseudoaneurysm on the peripheral side of an anastomosis. The aneurysm was successfully occluded by injection of 2,000 units of thrombin into the aneurysm sac. There were no complications and she showed disappearance of the aneurysm.
