目的探讨彩色多普勒超声对脑梗死患者颈动脉粥样硬化斑块的诊断价值。方法选取2014年6月至2016年6月收治的64例脑梗死患者为研究对象,将其作为研究组,同期选取相同例数的健康体检者作为对照组,对两组受检者进行彩色多普勒超声检查,比较两组受检者颈动脉粥样硬化斑块情况。结果研究组斑块共检出63例(斑块128个),检出率为98.4%,其中软斑38个、溃疡斑64个、硬斑18个、扁平斑8个,对照组斑块共检出38例(斑块76个),检出率为59.4%,软斑29个、溃疡斑23个、硬斑16个、扁平斑8个,两组受检者的斑块检出率及斑块检出不同类型比较差异有统计学意义(P<0.05)。两组受检者的两侧动脉PSV、EDV和RI比较,研究组患者的各血流动力学指标均低于对照组,差异均有统计学意义(均P<0.05);研究组患者的中度及重度狭窄率均高于对照组,差异有统计学意义(P<0.05)。结论脑梗死患者的颈动脉粥样硬化与健康体检者存在巨大差异,尤其在斑块类型和数量方面,可见脑梗死与颈动脉粥样硬化存在一定的联系,临床需引起注意。 Objective To investigate the diagnostic value of color Doppler ultrasound in carotid atherosclerotic plaques in patients with cerebral infarction. Methods Sixty-four patients with cerebral infarction who were admitted from June 2014 to June 2016 were selected as the research group, the same number of healthy subjects were selected as the control group in the same period, Pulmonary ultrasound examination, carotid atherosclerotic plaque comparison between two groups of subjects. Results A total of 63 plaques (128 plaques) were detected in the study group with a detection rate of 98.4%, including 38 soft spots, 64 ulcer spots, 18 hard spots and 8 flat plaques. 38 cases (76 plaques) were detected, the detection rate was 59.4%, 29 soft spots, 23 ulcer spots, 16 hard spots and 8 flat plaques. There were significant differences in different types of plaque detection (P <0.05). Compared with PSV, EDV and RI of arteries on both sides of the two groups, the hemodynamic indexes in the study group were lower than those in the control group (all P <0.05). In the study group, Degree and severe stenosis rate were higher than the control group, the difference was statistically significant (P <0.05). Conclusion There is a great difference between carotid atherosclerosis and healthy subjects in patients with cerebral infarction. Especially in terms of plaque type and quantity, there is a certain relationship between cerebral infarction and carotid atherosclerosis, and clinical need to pay attention.
