Abstract
Vascular bruits result from loss of laminar flow in blood vessels. Increased blood velocity or vessel tortuosity cause turbulence, which produces vibration of the vessel wall. If laminar flow is maintained, even with increased blood velocity, no bruit will result (Fig. 7.1). Neck bruits conducted from cardiac murmurs, e.g., aortic stenosis, similarly represent carotid wall vibration secondary to turbulence distal to the abnormal heart valve.
Where observation is concerned, chance favours only the prepared mind.
Louis Pasteur, 1822–1895
