Recurrent Stenoses in Arteriovenous Fistula (AVF) for Dialysis Access: CuttIng ballooN angioplaSTy Combined wITh Paclitaxel drUg coaTed Balloon Angioplasty, an observatIONal Clinical Study

To determine if cutting balloon angioplasty combined with DEB angioplasty provides a higher primary patency after treatment of recurrent stenoses compared with cutting balloon angioplasty or angioplasty using DEB alone in the venous outflow AVFs. For cutting balloon angioplasty in venous stenosis, the primary patency after 12 months is 55-60% (9,16) and in recurrent stenoses up to 48%(10). We hypothesise that DEB angioplasty after cutting balloon angioplasty leads to improved primary patency at 12 months.
