Abstract:
The coexistense of an abdominal aortic aneurysm with ectopic main renal vasculature complicates aortic surgery and mandates a focused imaging evaluation and a carefully planned operation to minimize renal ischemia. We present the case of a 75-year-old man with an abdominal aortic aneurysm and a right kidney with two ectopic main renal arteries, one originating from the aneurysmal distal aorta and the other from the right common iliac artery; the patient underwent a surgical repair and followed an uneventful course with no deterioration of renal function. The preoperative and intraoperative details are reported, along with a review of the literature.
