[Renal autotransplantation for dissecting aneurysm].
Out of twenty-five patients operated on for dissecting aneurysm in our institution since January 1991, four patients had autotransplantation of the kidney. The renal autotransplantation and the segmental replacement of the descending aorta with the prosthesis were done at the same time in three of them, and segmental replacement of the distal aortic arch was followed by autotransplantation because of the postoperative acute renal failure in the other one. Postoperative renal function of simultaneously operated patients was good whereas the patient who had been treated by two-staged operation needed hemodialysis for two weeks after the autotransplantation. Postoperative scintigraphy showed fully recovered function of the autotransplanted kidneys with enlargement. CT scan showed that the false lumen of the dissecting aorta was reduced in size with increased intraluminal clot formation. Renal autotransplantation with entry closure is easy and safe technique and assures successful operative results for the dissecting aneurysm, restoring impaired renal blood flow.
