The applied angiographic examination technique of the renal homotransplants performed during a 14-year period has been reported. 101 patients underwent 132 angiographic examinations in the course of 1971-1985. Thirty-two various vascular complications were diagnosed. Arterial stenoses during anastomoses were most frequent. Thromboembolic complications were second (4 arterial, 2 venous). One thrombosis of the iliac artery as a consequence of a wound infection following renal transplantation is described. In addition there were a few other single pseudoaneurysms of the arterial anastomoses and arteriovenous fistulas subsequent to renal biopsies. The importance of this examination technique and the diagnostic use of angiographic investigation of the transplanted kidney is pointed out.
