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

Objectives: to evaluate the feasibility of treatment of post-catheterisatio n pseudoaneurysms with duplex-guided thrombin injection. Technique: the technique of duplex-guided injection of thrombin in post-cat heterisation pseudoaneurysms of the femoral artery is described and illustr ated. Results: between December 1998 and October 1999, eight post-catheterisation pseudoneurysms of the femoral artery were successfully thrombosed with thr ombin injection. One patient developed a new pseudoaneurysms of the femoral artery this was also successfully treated with thrombin. Follow-up duplex- scanning at 3 months revealed no recurrences. No other adverse events occur red. Conclusions: this initial experience suggests that duplex-guided thrombin i njection in the treatment of post-catheterisation pseudo-aneurysms is feasi ble and safe.
