[Indications and results of caval filter operation using the Kimray-Greenfield filter].

Recurrent pulmonary embolism is a permanent risk. The caval filter is able to prevent embolism. The implantation can be done even in seriously ill patients under local anesthesia. In our patients no complication or recurrent embolism were observed. Only one case developed a thrombotic occlusion of the Kimray Greenfield filter as a result of retroperitoneal carcinosis. The relapse of embolism was prevented by the filter. All other implants were seen patent in the digital subtraction angiography.
