Abstract

We describe a case of fusiform aneurysm of the renal artery on a background of dolichoectasia in a kidney recovered from a deceased donor. The donor, a 57-year-old female, had died of an extensive nonsurvivable subarachnoid hemorrhage. Fusiform aneurysms involving the main renal artery and its superior branch had extended into the hilum with insufficient accessible stump for safe reconstruction. Placement of a stent through an intraoperative radiologic intervention was not possible without compromising renal perfusion. Consequently, renal transplant did not proceed. Dolichoectasia is a condition associated with generalized weakness of the arterial vascular wall and may result in aneurysm formation. When the renal artery is involved, a safe reconstruction excising the aneurysmal segment may be considered before transplant of the kidney.
