As institutional protocol, is performed to investigate the causes of cerebral ischemic accident. Doppler US is by far the most common imaging examination performed worldwide to aid in the diagnosis of carotid disease.
1 - It is observed diffuse thickening of the intima-media complex (> 8.0mm) along the left common carotid. Small soft plates with regular surface are see along the vessel lumen.
2 - Common carotid artery spectral wave shows a arrhythmic flow with with a normal value to systolic peak.
3 - Protruding atheromatous plaques in the carotid bulb, predominantly calcified, which promote vascular lumen stenosis.
4 - The external carotid artery shows high speeds on systolic peak (v = 426.7 cm / s). Internal carotid artery: high peak systolic velocities (v = 411.7 cm / s). There are swirling flow, observed by color Doppler mapping.
Right side: There is total obstruction of the right internal carotid artery.
