目的:探讨脑梗死(CI)患者多层螺旋CT(MSCT)血管成像特点。方法:对214例CI患者采用MSCT血管成像检查,观察其颈内动脉及分支血管、椎基底动脉及分支血管,分析动脉的形态、狭窄程度及斑块特点。结果:本组颈内动脉系统闭塞或狭窄以颈内动脉起始部为主,其发生率为74.3%;椎基底动脉系统闭塞或狭窄以椎动脉起始部及锁骨下动脉为主,其发生率为37.9%;颈内动脉系统闭塞或狭窄的发生率高于椎基底动脉系统闭塞或狭窄。结论:MSCT血管成像技术是颅内外血管性病变的无创检查方法,可作为CI患者血管狭窄分析及动脉斑块分析的首选检查方法之一。
Objective: To investigate the characteristics of multi-slice spiral CT (MSCT) angiography in patients with cerebral infarction (CI). Methods: MSCT angiography was performed in 214 CI patients. The internal carotid arteries and branches, vertebrobasilar artery and branch vessels were observed. The morphology, stenosis and plaque characteristics of the arteries were analyzed. Results: The incidence of internal carotid artery occlusion or stenosis was 74.3%. The occlusion or stenosis of vertebrobasilar artery was dominated by the beginning of vertebral artery and subclavian artery. The rate of occlusion or stenosis of internal carotid artery was higher than that of vertebrobasilar artery occlusion or stenosis. Conclusion: MSCT angiography is a noninvasive method for extracranial and extracranial vascular lesions. It can be used as one of the first choice for vascular stenosis and arterial plaque in CI patients.
