Abstract:
Objective To evaluate efficacy of percutaneous transluminal angioplasty (PTA) and stenting for treatment of transplanted renal artery stenosis (TRAS). Method Seven patients with TRAS were included in this study. By femoral or axillary approach, balloon angioplasty and /or metallic stents placement at stenostic renal artery were performed. Results Of the seven patients, balloon angioplasty was carried out in 3 (2 cases via femoral artery, 1 via axillary artery), both balloon angioplasty and metallic stents placement were performed in 4 (2 via femoral artery, 2 via axillary artery). After the procedure, blood pressure recovered to normal in 5 cases, controlled with administration of antihypertensive in the other 2 cases. By 9 to 36 month′s follow up, restenosis of renal artery occurred in only 1 case at 9 months after stent implantation. The second balloon angioplasty were taken and better renal artery blood flow was obtained in this case. Other 6 cases showed no restenosis. Conclusion PTA and stents placement were effective and safe approach in treatment of TRAS. Further investigation was needed to prevent and manage restenosis after these procedures.
