Abstract

Background: 

The anterior circulation is the blood supply to the anterior portion of the brain. Computed tomography angiography (CTA) is a noninvasive and effective anatomic evaluation method.

Objective: 

The objective of the study was to investigate the relationship between the diameters of the anterior circulation arteries and age, gender, and side using CTA.

Materials and Methods: 

In this single-center cross-sectional study, 200 cases that presented to the hospital between January 2019 and January 2022 were retrospectively examined using CTA. The diameters of the anterior circulation arteries (common carotid artery [CCA], internal carotid artery [ICA], anterior cerebral artery [ACA], medial cerebral artery [MCA], posterior communicating artery [PcomA], and anterior communicating artery [AcomA]) were measured and recorded by two radiologists. The mean diameters of CCA, ICA, ACA, AcomA, and PcomA were analyzed and compared based on age, gender, and side.

Results: 

The mean diameters of the right CCA, ICA, MCA, and ACA and the left CCA, ICA, and MCA were statistically significantly greater in the elderly (P < 0.001, P < 0.001, P = 0.01, P = 0.024, P < 0.001, P < 0.001, and P = 0.024, respectively). There was no statistically significant difference between the right and left vascular structures in CCA, ICA proximal, ICA distal, PcomA, MCA, and AcomA (P = 0.16, P = 0.48, P = 0.07, P = 0.62, P = 0.27, and P = 0.09, respectively). A statistically significant difference was observed between the right and left ACA in the whole cohort (P = 0.05). The mean diameters of the right CCA, ICA proximal, ICA distal, MCA, and ACA and the left CCA, ICA proximal, ICA distal, and MCA were statistically significantly higher in men than in women (P < 0.001, P < 0.001, P = 0.002, P < 0.001, P = 0.038, P < 0.001, P < 0.001, P = 0.002, and P < 0.001, respectively).

Conclusion: 

CTA is a valuable modality for vascular evaluation. It revealed statistically significant differences in anterior circulation based on age, gender, and side.
