Evaluation of Extracranial Vertebral Artery Stenosis and Extracranial Vertebral Artery Dysplasia by Cervical CTA

doi:10.7517/issn.1674-0475.220703

Abstract

Abstract: The value of cervical CT angiography (CTA) in evaluating extracranial vertebral artery stenosis and extracranial vertebral artery dysplasia was explored. Eighty patients with extracranial vertebral artery stenosis and dysplasia were selected as the study group, including 34 patients with extracranial vertebral artery stenosis (group A) and 46 patients with extracranial vertebral artery dysplasia (group B). During the same period, fifty healthy volunteers were selected as control group. All of them were given the CTA examination. The left vertebral artery (L-VA) diameter, L-VA area, right vertebral artery (R-VA) diameter, and R-VA area were recorded. Compared with the control group, the L-VA diameter, L-VA area, R-VA diameter and R-VA area of patients in group A and group B were all reduced (P<0.05). The total proportion of patients with extracranial vertebral artery stenosis and dysplasia on the right side was higher than that on the left side (P<0.05). The incidence of extracranial vertebral artery stenosis and dysplasia in female patients was higher than that in male patients (P<0.05). Cervical CTA can accurately assess extracranial vertebral artery stenosis and dysplasia, and has high clinical diagnosis and application value.

Key words: neck CT angiography, extracranial vertebral artery stenosis, extracranial vertebral artery dysplasia, diagnostic value
