Endovascular treatment of transplanted renal artery stenosis with PTA/stenting.

Abstract Purpose. We evaluated the effectiveness of endovascular treatment with percutaneous transluminal balloon angioplasty (PTA)/stenting of transplanted renal artery stenosis (TRAS). Materials and methods. Between January 2005 and December 2010, 17 patients (4 women, 13 men; mean age 60.9 years) with TRAS underwent PTA/stenting. The parameters analysed were: technical success, pre- and posttreatment serum creatinine (SCr) and blood pressure (BP), average number of antihypertensive drugs administeredbefore and after treatment and vessel patency on colour Doppler ultrasound (CDUS) at 1, 3, 6 and 12 months and once a year thereafter. Results. Technical success was 100%. During a mean follow-up of 28.3±18.7 months, there was a statistically significant reduction in SCr and BP values. In 18 % of cases, moderate (
