First seen Nov 01, 2025 · Last updated May 14, 2026 · Updated 22 times

Summary

This study looked at 66 adults with blocked dialysis grafts or fistulas to see if adding an ultrasound probe inside the blood vessel (IVUS) to regular X-ray imaging (angiography) helps doctors better understand and treat the blockages. The goal was to compare how well each method measures the narrowed areas. The study did not test a new treatment but aimed to gather information to improve future procedures.
