Abstract

Pelvic kidneys complicate aortic reconstructions because of increased risk of renal ischemia. Strategies for protection include shunting, cooling, and reliance on collaterals. A review identified two congenital pelvic kidney (not solitary) and five transplanted kidney patients who underwent elective abdominal aortic aneurysm repair. For congenital pelvic kidneys, topical cooling was used in one patient while no preservation was performed for the other patient. Three transplanted kidney patients were shunted, and one had endovascular repair. Postoperative creatinine values were compared to preoperative values. The two congenital pelvic kidney patients had no significant elevation of creatinine postoperatively. The transplanted kidney patient who underwent endovascular repair had no increase in creatinine postoperatively. All transplanted kidney patients who had open repair had significant but transient increase in creatinine postoperatively. Three patients who were shunted intraoperatively had normalization of creatinine. The patient who had persistent elevation of creatinine at discharge was not shunted. Aortorenal shunting or endovascular repair in transplanted pelvic kidney patients maintains renal function. For patients with congenital pelvic kidneys and adequate collaterals, cooling and collateral perfusion is usually sufficient. Though experience is limited, endovascular repair is likely to be superior to open repair in minimizing renal ischemia.
