目的探讨颈动脉斑块与脑梗死间的关系,为脑梗死的病因诊断、治疗和预防提供重要依据。方法选100例脑梗死患者进行颈动脉超声检查,了解有无颈动脉斑块并确定其大小、范围、斑块形态、内部回声特点,随机体检者100例作为对照组,分析斑块与脑梗死发生的相关性。结果脑梗死颈动脉斑块检出率为82%(82/100),显著高出对照组的斑块检出率24%(24/100),两组比较差异有统计学意义(P<0.05)。脑梗死的颈动脉斑块主要是易脱落的软斑(42%:8%)和混合斑(32%:2%)明显高于对照组(P<0.05);有颈动脉斑块的脑梗死患者复发率高于无颈动脉斑块的患者。结论颈动脉斑块及性质与脑梗死密切相关,软斑块是脑梗死发生的主要危险,也是脑梗死复发的主要原因,颈动脉超声检查对颈动脉斑块具有诊断价值,能及时发现斑块并准确定位,为临床干预提供可靠依据。
Objective To explore the relationship between carotid artery plaque and cerebral infarction and provide an important basis for the diagnosis, treatment and prevention of cerebral infarction. Methods 100 patients with cerebral infarction were examined by carotid ultrasonography to find out the presence or absence of carotid artery plaque and to determine its size, extent, plaque morphology and internal echo characteristics. 100 patients were randomly selected as the control group to analyze plaque and cerebral infarction Relevance that has occurred. Results The detection rate of carotid plaque was 82% (82/100) in cerebral infarction and 24% (24/100) in control group, the difference was statistically significant (P <0.05 ). Carotid plaques in cerebral infarction were predominantly flaccid (42%: 8%) and mixed plaque (32%: 2%), which were significantly higher than those in the control group (P <0.05) Patients with higher recurrence rate than those without carotid artery plaque. Conclusions Carotid plaque and its properties are closely related to cerebral infarction. Soft plaque is the main risk of cerebral infarction and the main reason of recurrent cerebral infarction. Carotid ultrasonography has diagnostic value for carotid artery plaque, and plaque And accurate positioning, to provide a reliable basis for clinical intervention.
