Doppler waveform parvus and tardus. A sign of proximal flow obstruction.

P S Kotval1.   

Abstract

The Doppler linear flow velocity versus time spectrum obtained in an arterial flow system in which there is proximal occlusive disease with or without collateral formation has a tardus-parvus waveform. The conditions that cause this Doppler sign are due to a poststenotic pressure drop.
