Brief Summary: The continuous increase in the incidence of end stage renal disease and hemodialysis patients has raised the interest of the vascular access scientific community and many researchers are currently investigating the potential mechanisms of arteriovenous fistulas AVF dysfunction Roy-Chaudhury et al were the first to suggest neointimal hyperplasia NIH as the main reason of AVF dysfunction and vessel negative remodeling as another important factor First Yamamoto et al described 3 stenotic lesions categories of arteriovenous grafts AVG observed by ultrasonography 1 vascular constriction type 2 neointimal hyperplasia type 3 mixed type constriction and neointimal hyperplastic type

The main goals of this prospective observetional study are

The characterization of AVF stenotic lesions by ultrasonography
The correlation of the stenotic lesion type with the outcomes of percutaneous transluminal angioplasty and the rate of reintervention
Detailed Description: This is a prospective observetional study designed to investigate the correlation of stenotic lesion type characterization 1 vascular constriction type 2 neointimal hyperplasia type 3 mixed type eg constriction and neointimal hyperplastic type using Duplex ultrasound with the outcomes of high pressure plain balloon angioplasty In total 200 patients with failing dialysis arteriovenoyus fistula AVF scheduled to undergo angioplasty of stenotic lesions will be included The studys primary endpoint will be the correlation between stenotic lesion type and target lesion re-intervention due to clinical recurrence at 6 months follow up
