[Vascular prosthesis in kidney transplantation].

OBJECTIVE

Three cases of kidney transplantation that required a vascular prosthesis are described and the literature reviewed.

METHODS

Of 920 cases of kidney transplantation, 3 required a vascular prosthesis to repair the aortoiliac vessels. One patient with severe atherosclerotic disease had an aorto-bifemoral prosthesis (Gore-Tex) six months before renal transplantation and the other two patients required a vascular prosthesis to repair iliac artery lesions discovered during transplantation.

RESULTS

The initial surgical results were satisfactory. No complications arising from the vascular prosthesis were observed. Two patients have a functioning renal graft, but the third patient developed acute tubular necrosis and tubulo-interstitial rejection and died from acute pulmonary edema.

CONCLUSION

The importance of the preoperative cardiovascular evaluation in patients undergoing kidney transplantation is underscored. Some patients may require a vascular prosthesis. We should therefore be familiar with the prosthetic materials and the surgical techniques, which are not particularly difficult, and optimum results can be achieved. In patients with both end-stage renal disease and severe aortoiliac atherosclerotic disease, the controversy remains whether aortoiliac repair and kidney transplantation should be done simultaneously or in two stages.
