1、Objective:
　　To assess the technical and clinical outcome of percutaneous transluminal balloon angioplasty and/ or stenting in the management of transplant renal artery stenosis (TRAS).
　　Methods:
　　From January

2、, 2011 to July, 2012 four patients underwent a total of 5 endovascular interventions for TRAS at our center. Their medical charts were retrospectively analyzed with particular interest in clinical presentation, time inte

3、rval from transplant to diagnosis of TRAS, diagnostic evaluation, location of stenosis, treatments, and both technical and clinical outcomes.
　　Results:
　　The technical success rate of PTA and/stent placement was 8

4、0％(4 of 5). Two PTA’s and 2 PTA/S were primary interventions and 1 PTA/S was subsequently performed due to re-stenosis (three weeks later). The mean follow up was 3 months. The mean pre-procedure serum creatinine level w

5、as 2.11 mg/dl, versus the 1-week post-procedure serum creatinine level was1.63 mg/dl, a reduction of 22.75%. The number of anti-hypertension medication remained the same pre and post procedure, but the mean pre-procedure

6、 diastolic blood pressure was 99.2mmHg while the post procedure diastolic blood pressure was 81.6mmHg, a reduction of 17.74%. Therefore all patients with successful PTAs and or PTAS attained clinical success. TRAS locati

7、on was anastomotic in 3 patients, and distal in 1 patient. The patency rates were 92%at 1 month, 84%at 3 months. No complications were encountered.
　　Conclusions:
　　Revascularization of TRAS with PTA and/ or stent
