Abstract :
The author discusses three major deviations from the traditional flow model: (1) flow separation in the normal carotid artery bulb; (2) major streamline deviations in linear vessel segments; and (3) in-line turbulence in a normal vessel. The method of high-resolution Doppler color flow imaging called angiodynography has been used to acquire the data. Schematics for the three major deviations are shown
