The thrill is a continuous buzzing sensation best felt with the palm over the venous outflow tract. The bruit is a low-pitched, continuous sound heard during both systole and diastole.
Absence of a previously documented thrill or bruit is a medical emergency indicating possible thrombosis. Notify the provider immediately to attempt salvage within hours. Never take blood pressure, perform venipuncture, or place restrictive devices on the fistula arm.
