Introduction:

Carotid echo-Doppler is the test of choice in the initial and follow-up study of atherothrombotic stroke.

Objective:

To describe echographic findings in both carotid axes in patients with atherothrombotic cerebral infarction of the homonymous vascular territory.

Methods:

Sixty-three patients underwent an observational and cross-sectional investigation at Dr. Carlos J. Finlay Central Military Hospital from October 2012 to September 2013. They have a clinical and tomographic diagnosis of atherothrombotic cerebral infarct from the previous territory and the underwent a carotid echo-Doppler.

Results:

We recorded higher number of atheromatous plaques in the homolateral carotid axis at atherothrombotic stroke (54.3%) and the majority was unstable (98.4%). Type III plate (50%), irregularity of the contour (54.1%) and less than 49% stenosis (57.6%) were the echographic findings that dominated the axis contralateral to the infarction. In both carotids, type III plaques (47.1%), irregularity of the contours (51.6%), non-significant stenosis (54.3%) and instability (94.4%) predominated.

Conclusions:

Carotid atherosclerosis in atherothrombotic stroke mostly describes the presence of irregular, type III plaques that cause stenosis of less than 49% in both carotid axes. The instability of them is almost constant, with a slightly higher incidence in the homolateral carotid axis to infarction. The frequency of the rest of the qualities of the listed atheromatous plaques slightly dominates in the contralateral carotid axis.
