Examining how ultrasound can predict angioplasty success in failing dialysis access
Characterization of STEnotic Lesion Type of Haemodialysis Arteriovenous Fistulae by Ultrasonography and Correlation With the Outcomes of Percutaneous Transluminal Angioplasty
This study is testing if ultrasound can help predict how well angioplasty will work for people with failing dialysis access by looking at different types of blockages in their blood vessels.

What this trial studies
This observational study aims to investigate the relationship between the types of stenotic lesions in failing arteriovenous fistulas (AVFs) and the outcomes of angioplasty procedures. Using Duplex ultrasound, the study will categorize stenotic lesions into three types: vascular constriction, neointimal hyperplasia, and mixed. A total of 200 patients scheduled for angioplasty will be monitored to assess how these lesion types correlate with the need for reintervention within six months. The findings could enhance understanding of AVF dysfunction and improve patient management strategies.
Who should consider this trial
Good fit: Ideal candidates are patients with failing arteriovenous fistulas scheduled for angioplasty.
Not a fit: Patients undergoing dialysis via arteriovenous grafts or those with contraindications to angioplasty will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to better prediction of angioplasty outcomes, ultimately improving the management of dialysis access for patients.
How similar studies have performed: Previous studies have suggested the importance of lesion characterization in predicting angioplasty outcomes, indicating potential for success in this approach.
