Ruptured Abdominal Aortic Aneurysm in a Patient with Congenital Fused Pelvic Kidney: A Case Report of Emergency Endovascular Treatment.

A 90-year-old male developed acute onset of abdominal and lumbar pain due to the rupture of an 11-cm abdominal aortic aneurysm. A congenital fused pelvic kidney perfused by three renal arteries arising from iliac axes was detected. In an emergent setting, an aorto-uni-iliac endograft was deployed through right femoral surgical access with occlusion of the upper right renal artery. An occluder device was placed in the common iliac artery above the renal artery through left femoral access. A femorofemoral crossover bypass completed the procedure. The patient developed acute renal failure, with no dialysis necessity. One-month computed tomography angiography showed procedure success.
