Assessment of hemodialysis access performance by color-flow Doppler ultrasound.

Hemodialysis access failure is a major cause of morbidity for patients with end stage renal disease with costs in excess of $743 million annually. Color-flow doppler ultrasound is the only mobile noninvasive technique that provides direct visual imaging of the access and measurement of access flow. Doppler ultrasound can identify patients at increased risk of future thrombosis and allow preventive intervention. Prospective trials show that ultrasound-based access management programs can decrease thrombosis rates, prolong access longevity, and decrease the cost of hemodialysis access management. It should be included as part of a coordinated program of hemodialysis management.
