Aortoiliac surgery and kidney transplantation

Abstract

Between January 1980 and December 1989, we performed 407 renal transplantations. Twelve of these patients (3%) underwent aortoiliac reconstruction before (Group I, two patients), concomitant to (Group II, five patients) or after (Group III, five patients) renal transplantation. The aortoiliac lesions treated included four aneurysms and seven occlusions of the abdominal aorta and one postarteriography dissection of the iliac artery. A prosthetic graft was inserted in nine cases (75%). Endarterectomy was performed in the three other cases (25%). Four of five patients in Group III were operated on without any particular protection for the transplant. There were no postoperative deaths in Groups I and III. In Group II, one patient died of infection secondary to a urinary tract fistula. Early and late vascular morbidity (renal artery stenosis, occlusion of aortoiliac reconstruction, anastomotic false aneurysm) occurred with equal frequency in the three groups. Renal transplantation in patients having already undergone aortoiliac surgery and, conversely, aortoiliac reconstruction in the renal transplant patient, are possible without any particular technical precautions with minimal mortality and kidney morbidity. Simultaneous renal transplantation and aortoiliac reconstruction carries a significant risk of infection and a two-stage procedure should be considered in this situation.
