MRA study of anatomical variations of circulus arteriosus cerebri in healthy adults of Kosova

摘要

BackgroundThe purpose of the study is to research the distribution of variations of circulus arteriosus cerebri (CAC) and determined diameters of arteries on healthy adults of Kosovo's population.MethodsThis observational descriptive study was conducted on 513 healthy participants who underwent 3D time-of-flight MR angiogram (3D-TOF MRA). Were measured diameters of arteries forming the CAC and the correlation of diameters between to age and sex. Also, the anatomical variants of the anterior and posterior components of the CAC were studied.ResultsIn the present study the typical variant of CAC was visible in a small number of patients, in 23.4% of cases and was slightly higher in females (25.1%) and young than males (21.2%) and older subjects. The complete anterior CAC is common with 77.7% of the all subjects, while the posterior part had a complete structure in 27.6% of the cases. The diameter of ICA is bigger on younger (p?
