WCN25-536 TRANSRADIAL APPROACH FOR PERCUTANEOUS ENDOVASCULAR INTERVENTIONS OF DYSFUNCTIONAL ARTERIO-VENOUS FISTULA (TAPE- AVF): SAFETY AND OUTCOMES STUDY

Percutaneous transluminal angioplasty (PTA), an established therapy to salvage dysfunctional arteriovenous fistula (AVF), is mostly performed via retrograde transvenous approach through the outflow vein of the AVF. The transradial approach, a standard of care in coronary artery interventions, has not been extensively studied for AVF interventions even though it carries the advantage of direct visualization of the whole AV access with a single contrast injection and provides direct guidewire access to both the inflow and outflow of the AVF without need for additional sheaths.
