[Renal cryopreservation in 2 renal transplant patients undergoing aortic surgery]

Acute kidney failure is one of the most severe complications of surgery on the aorta. We describe two kidney-transplanted patients diagnosed of aneurysm of the abdominal aorta who underwent resection of the aneurysm and placement of an aorto-aortic graft. Cryopreservation of the renal implant was used with good results. Prevention of kidney damage also requires maintenance of adequate intravascular volume and the use of drugs (dopamine, mannitol and furosemide) to increase renal blood flow and urinary output.
