Question

Quizplus · Accepted Answer

The prolonged pulsation in an AV graft or fistula is called a graft thrill. It is caused by turbulent blood flow as it moves through the access site. The term "bruit" is also used to describe the sound of turbulent blood flow, but it specifically refers to the sound heard with a stethoscope. "Shunt" refers to any connection between two blood vessels that bypasses an organ, while "flapper pulse" is not a recognized medical term.
