目的探讨颈部螺旋CT血管造影(CTA)对缺血性脑血管病的临床应用价值。方法回顾分析114例缺血性脑血管病患者的颈部CTA检查资料。结果114例腔隙性脑梗死和椎基底动脉供血不足患者,颈部CTA总异常率为78.9%。单纯前循环病变20例,单纯后循环病变21例,前后循环共同病变49例。其中动脉内膜明显增厚49支血管,轻度狭窄109处,中度狭窄26处,重度狭窄5处,血管闭塞9条,血管发育异常6条,骨刺压迫椎动脉4处,血管内软斑形成60处,血管钙化斑118处。结论颈部CTA无创、快速、三维图像、可任意旋转、可清晰地显示颈部血管形态及其毗邻关系,对于寻找缺血性脑血管病的病因特别是椎基底动脉供血不足的病因方面具有十分重要的临床价值。
Objective To investigate the clinical value of cervical spine CT angiography (CTA) on ischemic cerebrovascular disease. Methods A retrospective analysis of 114 cases of ischemic cerebrovascular disease in patients with neck CTA examination data. Results In 114 patients with lacunar infarction and vertebrobasilar insufficiency, the total abnormal rate of cervical CTA was 78.9%. Simple anterior circulation lesions in 20 cases, simple retroperitoneal lesions in 21 cases, before and after the cycle of common lesions in 49 cases. The arterial intima significantly thickening 49 vessels, 109 mild stenosis, 26 moderate stenosis, 5 severe stenosis, vascular occlusion 9, vascular dysplasia 6, bone spur compression of the vertebral artery 4, soft spot of blood vessels 60 formed, vascular calcification 118 spots. Conclusion The noninvasive, rapid and three-dimensional images of cervical CTA can be rotated freely, which can clearly show the morphology of the neck and its adjacent relationship. It is very useful in finding the cause of ischemic cerebrovascular disease especially the vertebrobasilar insufficiency Important clinical value.
