Inclusion Criteria:  Recurrent stenoses (within 1 year after angioplasty) in the venous outflow of AVFs for dialysis access (> 0.5cm from AV anastomosis up to cephalic arch) Successful guidewire crossing of target lesion ≥ 21 years old Informed and valid consent given. Patient willing and able to return for follow up .  Exclusion Criteria:  Thrombosed AVFs or occlusions in the access circuit Significant cephalic arch (central perpendicular portion of the cephalic vein) or central vein stenoses. > 3 stenosed segments (lesions are considered separate if they are separated by at least 2 cm normal vessel.) Only potential target lesion located in cephalic arch, central veins or anastomotic lesions. Only de novo stenoses identifiable as target lesion. Target lesion resistant to cutting balloon angioplasty (>30% residual stenosis with incomplete effacement of the lesion during cutting balloon angioplasty) Target lesion not treatable with the available sizes of cutting balloon (4-7mm) and drug eluting balloon (up to 8mm) so native reference vessel <3 mm or need for DEB balloon >8mm. Lesion in excess of 8 cm Unable to take dual antiplatelet therapy for 1 month and/or aspirin for 6 months Coagulopathy (PT or PTT >1.5 times the median of normal range) or thrombocytopenia (platelet count <50,000 /μL) that cannot be managed adequately with periprocedural transfusion. Patient on Warfarin. Known allergy to iodinated contrast that cannot be managed adequately with pre-procedure medication. Allergy / contraindication to dual anti-platelet therapy (aspirin and clopidogrel or ticlopidine) or paclitaxel. Acute infection over proposed puncture site. Women who are breastfeeding, pregnant or planning on becoming pregnant during study. Participant with medical conditions, which in the opinion of the investigator may cause non-compliance with protocol. Currently participating in an investigational drug, biologic or device trial that may have an impact on the dialysis access or previous enrolment in this study.
