The whooshing sound of blood flowing through a dialysis fistula or graft, heard with a stethoscope — the audible twin of the thrill.
The bruit is the continuous, low-pitched 'whoosh' produced by turbulent blood flow through an AV fistula or graft, auscultated over the access. A healthy access has a continuous bruit throughout the cardiac cycle, loudest at the anastomosis. A high-pitched or discontinuous bruit can indicate stenosis downstream; a silent access means no flow. Daily thrill/bruit checks by the patient catch access problems early.
A continuous buzzing vibration felt over a functioning AV fistula or graft — the physical sign that blood is flowing well through the access.
The surgical connection created to allow blood to flow between the patient's circulatory system and the dialysis machine during hemodialysis sessions.
A surgical connection between an artery and a vein, typically in the forearm, created to provide reliable vascular access for hemodialysis.
