Percutaneous duplex-guided thrombin injection for treatment of iatrogenic femoral artery pseudoaneurysms.

Abstract

to evaluate the feasibility of treatment of post-catheterisation pseudoaneurysms with duplex-guided thrombin injection. the technique of duplex-guided injection of thrombin in post-catheterisation pseudoaneurysms of the femoral artery is described and illustrated. between December 1998 and October 1999, eight post-catheterisation pseudoaneurysms of the femoral artery were successfully thrombosed with thrombin injection. One patient developed a new pseudoaneurysm within 6 hours and this was also successfully treated with thrombin. Follow-up duplex-scanning at 3 months revealed no recurrences. No other adverse events occurred. this initial experience suggests that duplex-guided thrombin injection in the treatment of post-catheterisation pseudo-aneurysms is feasible and safe.
