title: A new device for vascular embolization: report on case of two pulmonary arteriovenous fistulas embolization using the amplatzer vascular plug.
abstract: A pulmonary arteriovenous fistula (PAVF) is a rare vascular malformation commonly treated by embolization with coils or balloons to prevent the risk of several serious complications such as cerebral embolism and brain abscess. A 32-year-old female with two PAVFs and neurological ischemic manifestations has been successfully treated by transcatheter embolization of both fistulas using a new device (Amplatzer Vascular Plug). This self-expanding cylindrical nitinol mesh cage with high radial strength allows a chance of relocation until properly positioned. It is preferred to coils or balloons because a large caliber of feeding artery implied high risk of uncontrollable distal embolization. There appear to be no reports in the literature concerning use of this device, which could represent a useful innovative tool in embolotherapies, especially in large vascular areas.
