RESUMEN
The characteristics of development of vascular lines are important for development and improvement of of surgical treatment, decreasing risk of complications and development of personalized approach to treatment of patients. The purpose of the study is to reveal prevalence of different variants of development of common carotid artery bifurcation and to assess their significance for clinical medicine. The sample included 70 volunteers of average age 43.4 ± 10.7 years. The 3D reconstructions of MRI data 1.5 T Brivo 355 were evaluated. The observation data was grouped and processed using software Microsoft Excel 2007 and IBM SPSS Statistics 20. To summarize the data, 5 main variants of location of great vessels were identified. The most rare types of development and course of carotid arteries in bifurcation area were variants "II" and "III" (8.2% of all observations). The most common development options were "I" (51.4%) and "IV" (31.4%). The variants "I" and "IV" were determined relatively evenly.The variants "II" and "III" were found on the right in 60% and 66.7% correspondingly and "V" option was found on the left in 61.5%. The typical options of location of carotid arteries near the bifurcation (variants "I" and "IV"), 82.8% in total. The cases of ventral position of external carotid artery (variants "II" and "V") were established in 12.9%. The variant III was found in 4.3% of all cases. The distribution of vascular development options depending on the gender of patients was investigated. The study did not reveal significantly pronounced deviations in distribution of variants of vascular development, taking into account the age factor. The mentioned data permits to judge with confidence about necessity of developing personalized treatment of diseases of carotid arteries, considering their anatomical features of development in bifurcation area.
