Acute dissection of the aorta in a kidney transplant patient.

Acute type IIIb dissection of the aorta was observed in a patient who had undergone kidney transplantation 5 years previously. Arteriograms showed that the true channel was compressed by the false channel, excluding the right common iliac artery to which the renal artery of the transplanted kidney had been anastomosed. The patient was treated successfully by fenestration of the abdominal aorta.
