A staged repair of crossed fused renal ectopia with complex abdominal aortic and iliac aneurysms

Abstract

Crossed fused renal ectopia in the presence of abdominal aortic aneurysms (AAAs) is a rare challenge to therapy. A 68-year-old man had a 6.9-cm AAA, a 6.6-cm left common iliac aneurysm, and a 3.2-cm right internal iliac aneurysm. He had multiple comorbidities and a right-sided crossed fused kidney supplied by two small renal arteries arising from the AAA. Aortorenal bypass with staged endovascular aneurysm repair was used to treat the aneurysmal disease. Two-stage open aortorenal bypass followed by endovascular repair for complex aneurysms is feasible in the rare patient with such a congenital anomaly.
