FERNANDEZ-BRITTO RODRIGUEZ, José E et al. Aterosclerosis de las carótidas: estudio patomorfológico y morfométrico utilizando el Sistema Aterométrico. Rev Cubana Invest Bioméd [online]. 1998, vol.17, n.2, pp.143-151. ISSN 0864-0300.

The right and left primordial carotid arteries and the 3 proximal cms of their internal and external bifurcations in 201 necropsies that met the requirementes to be considered a consecutive series were analyzed. Age, sex, basic disease causing death and the direct cause of death were included in the analyses. For the pathomorphological and morphometric study, the arteries processed according to the international standards set by the World Health Organization (WHO). The arteries were qualitatively and quantitatively examined by applying the atherometric system (AS), which is regarded by WHO as the best methodology to study and characterize the atherosclerotic lesion. To this end, 4 age groups were formed: under 40, 40 to 59, 60 to 79 and over 79 years. The most outstanding results were the following: the atherosclerosis increases with rising age in all types of lesions and for all AS variables. The right carotid artery was the most affected in both male and female, the age at which fibrous plaques develop most was 40 to 50 years whereas the progression of the severe plaque was remarkably at 60 and over. Over 80 years-old people showed less severe and fibrous plaques than 60-79 age group. This research work resulted in the hypothesis that vascular geometry of carotid arteries may be responsible for a higher impact on the right side.
