Official Title: Efficacy and Tolerance of Transcutaneous Ionizing Radiations to Prevent Restenosis Caused by Intimal Hyperplasia on Prosthetic Haemodialysis Vascular Access
Brief Summary: Although ionizing radiations have been proposed for the prevention of intimal hyperplasia in coronary and peripheral arteries, information is lacking on how irradiation may prevent neointimal smooth-muscle cell proliferation and restenosis on prosthetic haemodialysis vascular access. We will assess the preventive effect of one dose of radiations (14 Gy) administered transcutaneously one day after dilatation of stenosis on prosthetic haemodialysis vascular access in a randomized controlled trial with a standardized clinical and ultrasonographic one-year follow-up.
