Direct percutaneous embolization of a postembolectomy pseudoaneurysm.

A case of direct percutaneous embolization of a large pseudoaneurysm of the posterior tibial artery is presented. The pseudoaneurysm developed following thrombectomy of an occluded femoropopliteal bypass graft with a Fogarty balloon catheter. Two needles were used: a 19-gauge needle to perform embolization and a 22-gauge needle for contrast injection. The two-needle technique allowed rapid, safe embolization with precise angiographic control of the embolization procedure.
