Abstract

Objective. To study the influence of the bifurcation angle of the common carotid artery on changes in local hemodynamic parameters in isolation and in combination with other geometric parameters and systemic risk factors for atherosclerosis.

Material and methods. We analyzed the anatomy and geometry of the bifurcation of the common carotid artery (CCA) in patients without pathology. Geometric parameters were studied on the basis of computed tomography data of patients undergoing research at the Scientific Research Institute – Ochapovsky Regional Clinical Hospital No. 1 in Krasnodar for another reason not related to cerebral atherosclerosis. Using specialized software, geometric models were built and hemodynamics in the area of the bifurcation of the common carotid artery were studied. The data obtained answer the question about the dependence of hemodynamics on the magnitude of the CCA bifurcation angle.

Results. In total, the study included 85 models of CCA bifurcation, 47 (55.3%) female models of bifurcation, 38 (44.7%) male models. The relationship between the bifurcation angle and age, the presence of systemic risk factors for the development of atherosclerosis, as well as other geometric parameters of the CCA bifurcation was analyzed. A statistically significant relationship was found when comparing the bifurcation angle with age, the type of blood flow in the proximal part of the CCA, and the diameter of the ICA.

Conclusion. The bifurcation angle of the common carotid artery, when combined with systemic risk factors, or with an increase in the diameter of the ICA bulb, increases the likelihood of the formation of a carotid atherosclerotic plaque.
