title: Renal artery pseudoaneurysm occurring after partial nephrectomy.
abstract: Retroperitoneal hemorrhage resulting from intrarenal pseudoaneurysm formation has been reported after percutaneous renal surgery. However, although hemorrhage is a well-recognized complication of partial nephrectomy, hemorrhage caused by an intrarenal pseudoaneurysm after open partial nephrectomy is rare. We report a case of retroperitoneal hematoma associated with a renal artery pseudoaneurysm occurring in a 56-year-old woman 2.5 weeks after she underwent left partial nephrectomy for renal cell carcinoma. The pseudoaneurysmal branch was successfully identified and selectively embolized using percutaneous renal arterial angiography.
