摘要/Abstract

摘要： 探究颈部CT血管造影（CTA）技术评估颅外段椎动脉狭窄及颅外段椎动脉发育不良的价值分析。选取80例颅外段椎动脉狭窄及发育不良患者为研究组，包括34例颅外段椎动脉狭窄患者（A组）、46例颅外段椎动脉发育不良患者（B组），并且选取50例同期健康志愿者为对照组，均进行CTA检查，记录患者左侧椎动脉（L-VA）直径、L-VA面积、右侧椎动脉（R-VA）直径、R-VA面积，并对患者颅外段椎动脉狭窄及发育不良左右两侧及性别比例情况进行分析。与对照组相比，A组、B组患者的L-VA直径、L-VA面积、R-VA直径、R-VA面积均减小（P<0.05）；研究组中，右侧发生颅外段椎动脉狭窄及发育不良患者总比例高于左侧（P<0.05）；女性患者发生颅外段椎动脉狭窄及发育不良比例高于男性患者（P<0.05）。颈部CTA对于颅外椎动脉狭窄及发育不良情况能够进行准确评估，临床诊断、应用价值较高。

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.
