颈动脉彩超检查对缺血性脑血管病的诊断价值

Carotid artery colour to exceed to check the value to the diagnosis of ischemic cerebrovascular disease

目的:探讨颈动脉彩超检查在缺血性脑血管病诊断中的应用价值。方法:分析45例经数字减影血管造影检查确诊的颈内动脉斑块患者的颈部彩超检查结果,并与同期颈部CTA检查结果进行比对。结果:彩超共42例检出斑块;检出硬斑13例,软斑33例,混合斑块18例,扁平斑块11例,其中兼有硬斑及软斑的10例;轻度颈动脉狭窄20例,中度狭窄18例,重度狭窄7例。同期CTA检出硬斑13例,非钙化性斑块49例,混合斑块21例,两种方法检出率比较无显著性差异(P>0.05)。结论:颈动脉彩超简便易行、无创、经济,并有效显示颈部血管的形态、管腔情况、狭窄程度等,与CTA检查相比发现斑块及判断斑块性质的能力相当,可作为缺血性脑血管病评价的首选方法及筛查方法。

To investigate the carotid artery colour to exceed examination in the diagnosis of ischemlc cerebrovascular disease. Methods： analysis of 45 cases confirmed by digital subtraction angiography of internal carotid artery plaque in patients with cervical eolour to exceed examination results, and compared with the neck CTA inspec- tion results. Results： colour to exceed a total of 42 cases detected patches; Check out hard spot 13 cases, soft spot 33 cases, 18 cases of mixed plaques, flat plaque in 11 cases, including 10 cases of both hard spot and soft spot; Mild 20 patients with carotid artery stenosis, moderate stenosis in 18 cases, 7 cases of severe stenosis. CTA detection hard spot 13 cases during this period, the soft spot of 37 cases, 21 cases of mixed plaques, flat plaque 12 cases, two methods detection rate was no significant difference （P〉 0.05）. Conclusion： carotid artery colour to exceed, noninvasive, econ- omy, and can effectively show the neck vascular morphology, lumen, degree of stenosis, compared with the CTA in- spection found plaque and judge the ability of nature, can be used as the preferred method of evaluation of ischemic cerebrovascular disease and clinical screening method.
