Morphological Characteristics of the Posterior Cerebral Circulation: An Analysis Based on Non-Invasive Imaging

Özet

AIM: To provide measurements of the posterior cerebral circulation using a non-invasive imaging modality.MATERIAL and METHODS: One-hundred and twenty patients aged from 12 to 76 years were analyzed using computedtomography (CT) angiography. Measurements of vertebral arteries (VA), basilar artery, posterior cerebral arteries (PCA) and posteriorcommunicating arteries were obtained. Basilar artery appearance and curvature were also noted. Differences between sides,genders and age groups were evaluated.RESULTS: Mean diameter of left VA was 2.36±0.81 mm, and mean diameter of right VA was 2.14 ± 0.79 mm. Mean length of basilarartery was 34.07 ± 5.53 mm in males, and 30.79 ± 4.18 mm in females. There was a significant difference in basilar artery lengthbetween genders: males had a longer basilar artery (p 0.05).CONCLUSION: Modern non-invasive imaging modalities can provide precise and useful information for vessels analysis. Thisinformation may be useful for planning and performing neuro-interventional procedures as well as posterior cranial fossa surgeries.
