Abstract

Background: Posterior circulation of brain is important because of vital organs’ blood supply provided by them. In this study, we evaluate the relationship of posterior circulation measurements with age, gender and side by using computed tomography angiography (CTA) images.

Materials and methods: A total 199 brain CTA examinations were retrospectively analyzed for all posterior circulation arteries (vertebral artery (VA), basilar artery, posterior cerebral artery (PCA), superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA)) to compare the difference based on age, gender and side.

Results: There is no correlation between age and the mean diameters of all vessels (p>0.05). The mean diameter left vertebral artery was higher than right vertebral artery in all genders (p:0.004 for males and p<0.001 for females). The mean diameter left SCA and PICA were higher than right SCA and PICA in females (p:0.032 and p:0.027, respectively).  The mean diameters of basilar, left PCA, left SCA, left vertebral, right PCA, right SCA, right PICA and right vertebral artery were higher in males and that differences were statistically significant (p<0.001, p:0.002, p:0.006, p:0.004, p:0.001, p:0.003, p:0.002 and p:0.006, respectively).

Conclusion: The posterior circulation vessel diameter is not affected by aging. The mean diameters of basilar artery, both PCAs, both SCAs, right PICA, both vertebral arteries were higher in males. The mean diameters left vertebral artery is higher than right in all genders.
