Abstract

A patient with a functioning renal transplant presented for treatment 8 years after operation with acute retroperitoneal hemorrhage ipsilateral to the allograft. A ruptured false aneurysm of the lumbar artery was identified and was treated initially with balloon catheter occlusion, then operative ligation, with satisfactory result.
