目的比较颈动脉超声与颈部多排CT血管造影(CTA)在脑梗死患者中的诊断价值。方法 50例脑梗死患者作为研究对象,所有患者均采用颈动脉超声和CTA进行检查,比较两种方法检测脑梗死患者颈动脉狭窄的优缺点。结果超声检查出左侧狭窄10例,右侧狭窄9例,双侧狭窄21例,与CTA检查出的10、11、19例比较,差异无统计学意义(P>0.05)。CTA与超声对颈动脉斑块分布情况比较,差异无统计学意义(P>0.05)。超声检出颈动脉重度狭窄患者3例,并经脑血管造影(DSA)证实,但在CTA检查中被诊断为完全闭塞。结论超声与CTA在评价血管狭窄程度方面具有良好的一致性,对斑块检出率差异不大,但对于重度狭窄超声检查准确性更高。
Objective To compare the diagnostic value of carotid ultrasonography and multislice CT angiography (CTA) in patients with cerebral infarction. Methods Fifty patients with cerebral infarction were studied. All the patients were examined by carotid ultrasonography and CTA. The advantages and disadvantages of two methods in detecting carotid stenosis in patients with cerebral infarction were compared. Results Ultrasonography showed 10 cases of left stenosis, 9 cases of right stenosis and 21 cases of bilateral stenosis. There was no significant difference (P> 0.05) between 10 and 19 cases detected by CTA. CTA and ultrasound distribution of carotid plaques, the difference was not statistically significant (P> 0.05). Three patients with severe carotid stenosis were examined by ultrasound and confirmed by cerebral angiography (DSA), but were diagnosed as completely occluded by CTA. Conclusion Ultrasound and CTA have good consistency in evaluating the degree of vascular stenosis. The detection rate of plaque is not different, but the accuracy of ultrasonography in severe stenosis is higher.
