An interventional study of Active ultrasound surveillance of fistula and proactive treatment of stenosis in Renal Failure and Arteriovenous Fistula, sponsored by University of Hull. Withdrawn at 1 site in United Kingdom. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-03-22.
Sponsored by University of Hull · Not applicable, Interventional, and Prevention
Newly formed dialysis fistulae can often fail, and failure is usually due to narrowing of the blood vessels. Methods of detecting narrowing are available and, more importantly, can detect narrowings before a fistula fails. It is not known whether treating these narrowings will actually improve fistula survival or if the majority can be left alone. we wish to see if we can detect such narrowings with ultrasound scanning and if early detection and treatment improves patient outcomes.
