Renal Artery Pseudoaneurysm Following Partial Nephrectomy: Report of a Case and Review of the Literature

Delayed hemorrhage related to partial nephrectomy may be a life-threatening condition because of the diagnostic difficulties. Although hemorrhage is a well-recognized complication of partial nephrectomy, hemorrhage caused by a renal artery pseudoaneurysm after open partial nephrectomy is rare. We report a case of retroperitoneal hematoma associated with a renal artery pseudoaneurysm occurring in a 48-year-old male three days after he underwent right partial nephrectomy for renal cell carcinoma. With early suspicion, the pseudoaneurysmal branch was successfully identified and selectively embolized using percutaneous renal arterial angiography.
