title: Percutaneous transluminal angioplasty in transplant renal artery stenosis: experience and review of the literature.
abstract: Percutaneous transluminal angioplasty (PTA) was performed in five instances of renal transplant artery stenosis (RTAS) in four patients. Hypertension was present in all cases and improved after angioplasty together with reduction in medicine requirements. Abnormal renal function in four instances also improved after PTA. This reflects the current literature in which 76 of 90 patients were successfully treated by PTA (follow-up to 24 months), with two cases of recurrent stenosis, no mortality, and only a single case of graft loss. Vascular surgical repair succeeded in 130 to 180 patients, but graft loss occurred in 20 cases and recurrent stenosis in 11. Mortality was reported in five cases. Our review of the literature and experience suggests that PTA may be preferred in the treatment of RTAS.
