Answer

A randomized study by van de Ven et al that compared percutaneous transluminal angioplasty (PTA) for ostial ATH with PTA with stent (PTAS) showed that PTAS is a better technique compared to PTA to achieve vessel patency in ostial atherosclerotic renal artery stenosis. [38] The primary success rate was 57% for PTA compared with 88% for PTAS. The restenosis rate after a successful primary procedure was 48% for PTA versus 14% for PTAS. In the last few years, the use of PTAS in patients with ostial stenosis or early restenosis has led to a considerable reduction in the restenosis rate.
