[Arterial stenosis in the renal graft. Indication for endoluminal dilatation]

One hundred and thirty eight patients with renal transplant artery stenosis were reported in a series of 1200 renal transplants. These cases included 47 patients in whom hypertension was well controlled by means of hypotensive drugs, 39 patients treated by surgical repair (SR) and 49 treated by percutaneous angioplasty (PTA). The long-term success rate was 81.5 percent in the SR group compared with 40.8 percent in the PTA group. PTA morbidity was greater than that of SR, and we believe that after the initial optimism, the results of this technique should be reevaluated according to the anatomical pattern of the renal artery stenosis.
