目的探讨超声诊断对颈动脉粥样斑块与脑梗死的临床应用价值。方法本院诊治的100例脑梗死患者作为观察组,给予颈动脉超声检查,了解是否存在颈动脉粥样硬化斑块,并且对其大小、斑块形态、内部回声等特点进行明确,选取体检中心100例健康体检者作为对照组,评价动脉粥样斑块与脑梗死发生的相关性。结果 100例脑梗死患者中,超声检查出不稳定性斑块60例(60.0%),硬斑15例(15.0%),内膜增厚但未形成斑块10例(10.0%),未形成斑块15例(15.0%),可见脑梗死中,不稳定性斑块为主。100例对照组患者中,超声检查出颈动脉粥样斑块18例(18.0%)。与对照组相比,超声检查出颈动脉粥样斑块的比率明显增高,P<0.05差异有统计学意义。结论通过超声诊断方法,对颈动脉粥样斑块特点进行评估,对于脑梗死的预防,具有明显的临床意义。
Objective To investigate the clinical value of ultrasonic diagnosis on carotid artery plaque and cerebral infarction. Methods A total of 100 patients with cerebral infarction treated in our hospital were selected as the observation group. The carotid artery was examined by ultrasonography to find out the existence of carotid atherosclerotic plaque. The characteristics of the carotid atherosclerotic plaque, plaque morphology and internal echo were determined. 100 healthy subjects as a control group, evaluation of atherosclerotic plaque and cerebral infarction related. Results Among the 100 cases of cerebral infarction, 60 cases (60.0%) of unstable plaques, 15 cases of hard plaque (15.0%), 10 cases of thickening of intima without plaque formation (10.0%) and no formation of plaque Plaque in 15 cases (15.0%), visible cerebral infarction, unstable plaque. Among 100 patients in the control group, 18 cases (18.0%) had carotid plaques by ultrasonography. Compared with the control group, the rate of carotid artery plaque was significantly higher than that of the control group (P <0.05). Conclusion Ultrasound diagnosis of carotid atherosclerotic plaque characteristics, for the prevention of cerebral infarction, has obvious clinical significance.
