WCN25-3998 PREDICTING VASCULAR ACCESS ANGIOPLASTY SUCCESS OR FAILURE WITH A DIGITAL STETHOSCOPE

Arteriovenous fistula (AVF) and arteriovenous graft (AVG) dysfunction, often as a result of a venous segment stenosis is a common cause of vascular access dysfunction that is most commonly treated with an endovascular procedure (angioplasty +/- stent placement). Although vascular access dysfunction results in a very significant morbidity, mortality and economic cost, the results of angioplasty in particular remain sub-optimal, with a 50-60% post-intervention unassisted primary patency rate at 6 months.
