Renal artery aneurysms in kidney grafts.
The shortage of organs has forced transplant surgeons to use grafts from marginal donors, even those presenting with important vascular alterations. In such cases, in-depth knowledge of the vascular anatomy and its variants, the correct identification and preservation of the arterial supply, and familiarity with microsurgical techniques for vascular reconstruction are mandatory. Renal artery aneurysms (RAAs) are an uncommon entity whose incidence is approximately .01%-.09% in the general population and .7%-.9% in subjects undergoing angiographic investigation. When present in renal grafts, they can be resected at the back-table and the graft can be successfully implanted.
