Infrarenal abdominal aortic dissection with aberrant renal arteries and lead-ing symptom right leg ischemia: case report.

INTRODUCTION Isolated infrarenal abdominal aortic dissection is a rare clinical entity. Most cases are treated by endovascular techniques, and open surgery is seldom necessary. CASE DESCRIPTION We present a rare case of spontaneous symptomatic infrarenal aortic dissection with leading symptom right leg ischemia. We opted for abdominal surgery as the attempt for open surgical fenestration of the dissecting flap exit through right femoral access was unsuccessful. Dacron vascular prosthesis was implanted with aortoiliofemoral bypass on the right side. One of the two accessory right renal arteries was ligated, which led to a confined zone of renal ischemia. Upon follow-up, complete restoration of the renal parenchyma was observed; kidney function remained unaffected. CONCLUSION By infrarenal abdominal aortic dissection with accessory renal arteries, abdominal surgery with selective clamping is a reliable therapeutic approach allowing maximal preservation of renal blood flow.
