目的:探讨超声筛查颈动脉狭窄与脑梗死的关系。方法:选取脑梗死住院患者156例作为本次研究的病例组,同期门诊就诊非脑梗死患者156例作为对照组。采用超声筛查方式比较两组患者颈动脉狭窄检出率并分析颈动脉狭窄与脑梗死的关系。结果:本次研究病例组检出颈动脉狭窄90例,其中轻度狭窄21例(13.5%),中度狭窄26例(16.7%),重度狭窄与闭塞检出43例(27.6%);对照组检出颈动脉狭窄19例,其中轻度狭窄检出10例(6.4%),中度狭窄检出7例(4.5%),重度狭窄检出2例(1.3%);病例组颈动脉狭窄检出率明显高于对照组。结论:颈动脉狭窄是脑梗死的重要危险因素;超声筛查颈动脉狭窄可作为预测脑梗死主要指标之一。
Objective: To investigate the relationship between stenosis of carotid artery and cerebral infarction by ultrasound. Methods: A total of 156 hospitalized patients with cerebral infarction were selected as the case group. 156 patients with non-cerebral infarction during the same period were selected as the control group. The ultrasound screening method was used to compare the detection rate of carotid artery stenosis in two groups and to analyze the relationship between carotid artery stenosis and cerebral infarction. Results: 90 cases of carotid stenosis were detected in this study group, of which 21 cases were mild stenosis (13.5%), 26 cases were moderate stenosis (16.7%) and 43 cases were severe stenosis and occlusion (27.6%). Nineteen patients had carotid stenosis, of which 10 (6.4%) had mild stenosis, 7 (4.5%) had moderate stenosis, and 2 (1.3%) had severe stenosis. The carotid stenosis The detection rate was significantly higher than the control group. Conclusion: Carotid artery stenosis is an important risk factor of cerebral infarction. Ultrasound screening of carotid artery stenosis may be one of the main indexes to predict cerebral infarction.
