Arteriovenous Fistula Clinical Trial
— PRESTOfficial title:
Randomized Trial Comparing a Cutting Balloon to a Non-cutting Balloon for the Treatment of Venous Stenosis in the Fistulas of Hemodialyzed Patients
The main objective of this study is to evaluate and compare the primary patency rate at 12 months in a group of hemodialysis patients operated on by cutting balloon and in a group of hemodialysis patients operated by conventional balloon.
