Primary Patency in Post-angioplasty Dysfunctional Arteriovenous Fistula in Renal Dialysis: Paclitaxel-releasing PTA Balloon Catheter vs PTA Balloon

In recent years the use of paclitaxel releasing percutaneous transluminal angioplastic (PTA) balloon catheter is spreading in vascular pathology, mainly in stenosis infrainguinal arteries. This device combined the mechanical action of PTA balloon with the antiproliferative effects of paclitaxel. The use of these devices in venous pathology is limited. This devices could improve the treatment of renal dialysis arteriovenous fistula stenosis.

Inclusion Criteria:

• Patient with renal dialysis with arteriovenous fistula (AVF) at least 3 months before.

• Sign informed consent

Exclusion Criteria:

• Pregnant or breastfeeding
• Patients with AVF stenosis not could be treated with PTA catheter
• Paclitaxel allergy
• Iodinated contrast allergy
