Clinical Trial Summary

To evaluate the preliminary efficacy of combination of cutting and drug-coated balloon for the treatment of resistant AVF stenosis.

Description:

This is a single arm pilot study recruiting 19 participants with resistant AVF stenosis (defined as having > 30% residual stenosis after optimal balloon angioplasty) to receive cutting and drug-coated balloon. The outcome measure is target lesion primary patency at 6 months. Outcome will be clinically driven.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 19
• Est. completion date: June 30, 2019
• Est. primary completion date: June 30, 2019
• Accepts healthy volunteers: No
• Gender: All
• Age group: 21 Years and older

Eligibility

Inclusion Criteria:

1. Failing mature upper limb AVF

2. Resistant stenosis (>30% residual stenosis) after optimal conventional balloon angioplasty (appropriately sized balloon, inflated up to rated burst pressure, at least twice for at least a minute per inflation)

3. Patient is >= 21 years of age

4. Ability to provide informed consent

Exclusion Criteria:

1. Thrombosed AVF

2. Target lesion has a sharp angle (> 45 degrees)

3. Lesions requiring cutting balloon size > 7 mm

4. Coagulopathy or thrombocytopaenia that cannot be adequately managed for the procedure

5. Contraindication to dual antiplatelet therapy

6. Severe allergy to contrast media that cannot be adequately managed for the procedure

7. Breast-feeding and/or pregnant females

8. Male patients who are planning to father children during the trial period

9. Unable to comply with follow up protocol (for instance, limited life expectancy)
