Renal artery pseudoaneurysm after open partial nephrectomy: a case report.

Although intraoperative hemorrhage is a well-recognized complication of open partial nephrectomy, postoperative hemorrhage caused by a renal artery pseudoaneurysm (RAP) after open partial nephrectomy is rare. We presented a case of RAP occurring in an 84-year-old man 3 weeks after right open partial nephrectomy for renal cell carcinoma. The pseudoaneurysmal branch was successfully identified and selectively embolized using percutaneous renal arterial angiography.
