Drug Coated Balloon in Dysfunctional Arteriovenous Fistula for Hemodialysis

Tuesday, September 19, 2023
2:50 PM – 3:00 PM US EDT
Location: Grand Ballroom A
Introduction, Objectives, and/or Purpose: Percutaneous transluminal angioplasty (PTA) is an established treatment of arteriovenous fistula (AVF) stenosis. Drug-coated balloons (DCB) are another promising option for treatment of these stenoses as they are coated with an antiproliferative drug intended to decrease neointimal hyperplasia and restenosis.

Purpose: To investigate the safety and patency of AVFs & AVGs following restenosis and re-occlusion after treatment with DCBs.

Methods: A prospective study including 20 patients, recruited from treatment registers, receiving at least one previous PTA and then re-intervention with DCB was done and were observed for 6 months. Patency after re-intervention was assessed clinically at different time intervals (1 week,2 weeks,1 month,3 months,6 months) and by duplex after 3 and 6 months. An intra-subject analysis comparing patency after previous conventional angioplasty and after DCB angioplasty was done.

Results: After 3 and 6 months, the estimated proportions of stenosis-free patients were 80 % and 65 %, respectively in the DCB angioplasty, compared to 70% and 30% in the previous PTA angioplasty.

Conclusion(s): Our results indicate that DCB angioplasty is associated with significantly improved patency in the treatment of restenosis. A longer follow-up and randomized controlled trial is warranted
