- Abstract
- Arterial anastomosis in transplant patients with severe aortic and iliac atheromatosis is technically challenging and may jeopardize the success of the transplantation procedure. The aim of this retrospective study was to report short- and long-term results of a consecutive series of kidney transplant patients in whom the renal artery was implanted on a prosthetic vascular graft. Medical charts and outpatient clinical records of patients who had undergone renal artery implantation on a prosthetic graft were reviewed. Data on patient characteristics, indications for transplantation, prior vascular procedures, surgical technique, and postoperative and long-term outcome were collected. The renal artery was implanted on a prosthetic graft in the course of 27 kidney transplantation procedures. Patients were divided into three groups according to the timing of the vascular intervention in relation to the transplantation. In group A (n = 22), the vascular prosthesis was implanted before kidney transplantation, in group B (n = 2), prosthetic iliac artery replacement and kidney transplantation were performed simultaneously, while in group C (n = 3), the vascular prosthesis was implanted after kidney transplantation. After a median follow-up of 50.5 months, one case of early arterial thrombosis was observed (3.7 %). Infectious complications occurred in two patients (7.4 %) related to mycotic pseudoaneurysms. One hematoma and one evisceration were also encountered, but no late arterial thrombosis nor stenosis were noted. Mean creatinine levels at 1 and 5 years of follow-up were 1.32 ± 0.36 and 1.27 ± 0.56 mg/dl, respectively. Five-year patient and graft survival rates were 85.2 and 74 %, respectively. Grafting of the renal artery to a vascular prosthesis is feasible and yields good results, despite the technical difficulties involved. We stress the importance of good teamwork.
