Morphometric Analysis Of Middle Cerebral Artery By Multi Detector Computed Tomography

Abstract

Middle cerebral artery is the thick one of two terminal parts of internal carotis artery. The objectives of this study are to obtain morphometric measurements for middle cerebral artery, to carry out morphologic typology, to observe different variations and to help similar anatomic and clinic studies. In our study, we retrospectively examined cranial images of 50 patients, 18 to 65 years of age, taken by Multi Detector Computed Tomography between the years 2015-2020, which are kept in the Radiology Department of Meram Medical Faculty, Necmettin Erbakan University. The measurements used in the study included diameter, cross-sectional area, lenght and angel details. Different variations were studied by morphologic typology and any cases with anomaly were also carefully evaluated. Our study enables to compare morphometric measurements with morphologic typology. Furthermore, both measurements and typology also helped to find out correlations between the side and the age and gender groups. As a result of this study, no statistically significant finding was existing in morphometric measurements to compare sexual differences. However, in the comparison of the sides, the fact that some parameters were higher in the right side, whereas some were higher in the left was found to be statistically significant. We did not observe any difference in mean values of the age parameters. Morphologically, the most common monofurcation in the furcation of M1 segment was the most prevalent in the typology from its lenght from the first branch to the second. We did not observe any aneurysm. Moreover, the accessory and duplicated middle cerebral artery was observed once in all cases and no fenestration was found. We believe that the study findings and typology of middle cerebral artery origin will make a new contribution to the literatüre and it will be useful from an anatomically and clinically.
