Aortoiliac reconstruction in preparation for renal transplantation.
Aortoiliac angiography has always been an integral part of the pretransplantation work-up of renal transplant candidates in Norway. The present study was undertaken to investigate the value of this routine. Based on the angiograms of approximately 1400 patients evaluated for renal transplantation during the 7-year period 1984-1991, 26 were found to have aortic and/or iliac atherosclerosis requiring pretransplant vascular reconstruction. Fifteen of the 26 patients had aneurysm of the abdominal aorta and 11 had extensive aortoiliac occlusive disease. A prosthetic graft was inserted in 25 patients and endarterectomy of the aortic bifurcation was performed in one. The cause of death was coronary heart disease in four of six patients who died before, and in one patient who died after, transplantation. Sixteen patients received a renal transplant while four patients are still on the waiting list. Fifteen of the recipients are alive, 14 with functioning renal transplants. The low yield of patients below 40 years of age requiring vascular reconstruction calls into question the routine use of angiographic investigation of renal transplant candidates below this age. However, we recommend this routine for the higher age groups because it often provides the surgeon performing the transplantation with valuable information. Aortoiliac reconstruction as preparation for renal transplantation is advocated when atherosclerosis of a degree that may preclude transplantation is found. Because of the high risk of myocardial infarction in these patients, one must be especially aware of coronary atherosclerosis when evaluating patients for this procedure.
