De novo renal artery aneurysm presenting 6 years after transplantation: A complication of recurrent arterial stenosis?

Pseudoaneurysms represent a well-recognized vascular complication of renal transplantation, but true aneurysms involving the donor renal artery have n ot been described. We report a patient who had a de novo aneurysm of the do nor renal artery 6 years after receiving a cadaveric renal transplant from a child. The aneurysm was repaired successfully, and allograft function was preserved. Histologic evidence confirmed that the lesion was a true aneury sm. Given the potential for graft loss associated with complications of unr epaired aneurysms, we believe that the presence of a true aneurysm in a don or renal artery represents an indication for repair.
