Clinical Trial Summary

The goal of this clinical trial is to compare plain old balloon angioplasty with sirolimus-coated balloon angioplasty in patients with an arteriovenous shunt stenosis. The main question we aim to answer is, how patency is affected by each of the randomised treatment modality.

Description:

This clinical trial will be conducted at our Division of Vascular Surgery and Endovascular Surgery at the University Hospital of Salzburg. Patients will be randomized into one of the two treatment options (plain old ballon angioplasty versus sirolimus coated balloon angioplasty). The recruitment phase is calculated for two years with a planned follow-up of 2 years. Follow-up data will be collected to answer the endpoints and will include all available follow-ups to monitor the shunt up to 2 years after the procedure. Typically, follow-up visits will be conducted at 6 weeks, 3 months, 6 months, 12 months, and 24 months after the procedure. The shunts are checked for functionality as part of the dialysis required three times a week and presented to our department beforehand in need. This saves chronically ill patients the additional waiting time in hospital outpatient departments.
