ABSTRACT

A partial nephrectomy is being used increasingly for the removal of renal cell carcinomas. A renal artery pseudoaneurysm (RAP) is a rare, potentially life threatening complication after a partial nephrectomy. This paper presents a case of spontaneous thrombosis of RAP after a partial nephrectomy. The presented case is believed to be the largest in diameter (59 mm) among the reported cases of spontaneous treatment of RAP by complete thrombosis.
