SUCCESSFUL TREATMENT OF AN IATROGENIC INFRARENAL AORTIC DISSECTION WITH SERIAL WALLSTENTS

We report a patient who presented with acute lower extremity ischemia 13 days following removal of an intraaortic balloon pump. Dissection o f the infrarenal aorta, extending into the left iliac artery, was foun d at operation. The patient's recent myocardial infarction, prolonged ischemia with compartment syndrome, otherwise normal aortoiliac and in frainguinal arteries and the necessity for suprarenal aortic clamping for surgical repair, were all factors in the decision for endovascular repair of the dissection. Infrarenal aortic and left iliac Wallstents , placed intraoperatively, successfully occluded the false lumen of th e dissection. The patient was discharged after an uncomplicated recove ry and is asymptomatic with palpable pedal pulses and triphasic pedal Doppler waveforms 1 year following the procedure.
