超声评价颈动脉粥样硬化与脑梗死的关系

目的探讨颈动脉粥样硬化与脑梗死的关系。方法 73例脑梗死患者和100例体检健康者为对照组,超声检测其颈动脉内-中膜厚度(IMT)、斑块回声类型。结果脑梗死组IMT高于对照组(P<0.05),脑梗死组颈动脉粥样硬化斑块检出率(84.9%)高于对照组(16.0%)(P<0.05);脑梗死组低回声斑块及混合性斑块多于对照组(P<0.05);高血压病、糖尿病、颈动脉IMT增厚、颈动脉粥样硬化斑块为低回声或混合性斑块是脑梗死发生的独立危险因素。结论颈动脉IMT增厚和粥样硬化斑块与脑梗死的发病密切相关,颈动脉超声检查能为临床预防和治疗脑梗死提供可靠依据。

Evaluation of the relationship between carotid atherosclerosis and cerebral infarction by ultrasound

Objective To explore the relationship between carotid atherosclerosis （CAS）and cerebral infarction by uhrasonography. Methods Seventy- three patients with cerebral infarction and 100 patients without cerebral infarction were enrolled in this study. Intima - media thickness （IMT） of carotid artery, echo type of carotid artery plaques were compared between the two groups. Results The IMT of patients with cerebral infarctionwas significantly higher than that of control group （ P 〈 0. 05 ）. The incidence rate of carotid atherosclerosis plaque in patients with cerebral infarction was 84.9% , which was significantly higher than that of control group （ 16.0% ） （ P 〈 0.05 ）. The ratio of hypoechoic and heterogeneous plaques in patients with cerebral infarction was higher than that of control group （P 〈 0. 05 ）. Hypertension, diabetes, IMT thickening, hypoechoic and heterogeneous plaques in carotid artery were independent risk factors for cerebral infarction. Conclusion The occurrence of cerebral infarction is closely related to the carotid atherosclerosis. Carotid ultrasonography can provide an evidenc, e for prevention and treatment of cerebral infarction.
