Use of a novel tapered, scoring balloon to treat juxta-anastomotic stenosis in AV fistula

Juxta-anastomotic stenosis, the most common lesion in arteriovenous fistula, creates a dilemma for optimal balloon size choosing during PTA.To descript the effect of a novel tapered scoring balloon catheter (DK Medtech, Suzhou, China) which has a conical shape with an increasing diameter from the front part of the balloon to the end, and three non-slip elements attached on the surface of the balloon.Case series of 10 patients used this balloon catheter was retrospectively analyzed.Patients with juxta-anastomotic stenosis.A retrospective review of 10 cases using the novel tapered, scoring balloon catheter in our center was performed.All cases were clinical technique success. The average total procedure time was 16.7 min with 2:14 of fluoroscopy time. No complications such as vascular rupture or dissection occurred. The primary patency rates at 6 and 12 month were 80% and 50% separately.This tapered scoring balloon provides an economical, safe, and efficient management for juxta-anastomotic stenosis.
