ABSTRACT

Introduction: stroke is the third cause of death in Cuba and its main cause is atherosclerosis. The end-result of both diseases is disability and loss of quality of life. The most commonly found etiology in Cuba is atherothrombotic stroke.
Objective: to describe the particularities of carotid atherosclerosis in patients with atherothrombotic stroke in homonym region according to CT-angiography.
Methods: observational, descriptive and cross-sectional studies on 42 patients with clinical and tomographic diagnosis of atherothrombotic brain stroke in the anterior region were made. All these patients underwent a carotid CT-angiography.
Results: mixed atheroma plaques were predominantly found in both carotid axes, accounting for 50 % in right carotid axis and 42.9 % in the left axis. Irregular outlines of plaques affected right axes in 54.8% and the left axes in 52.4 %. The predominant rank of stenosis in the left carotid was 70 to 99 % in 18 (42.9 %) patients, whereas it was 50 to 69% in the right carotid found in 14 (33.3 %) patients.
Conclusions: mixed plaques, unstable axes, irregular outlines and significant stenosis are predominant. The atherosclerotic lesion occurs bilaterally, being the low shear stress areas the most seriously affected as well as the right axle is the most affected.
