目的：探讨急性脑梗死与颈动脉粥样硬化斑块形成及斑块性质的关系，为脑梗死的预防和治疗提供治疗依据。方法应用彩色多普勒超声诊断仪对30例急性脑梗死患者与28例非脑血管病患者(对照组)进行颈动脉超声检查，观察颈动脉血管形态、血管管腔是否狭窄及狭窄的程度、观察动脉内膜中层厚度( IMT)、有无斑块形成及斑块的性质。结果(1)两组间管腔狭窄程度比较：脑梗死组中度狭窄50%~75%及严重狭窄>75%的比率高于对照组(P<0.05)；(2)脑梗死组IMT与对照组IMT比较无明显显著差异(P>0.05)；(3)脑梗死组软斑和溃疡斑的发生率高于对照组(P<0.05)；结论颈动脉狭窄可能导致急性脑梗死的危险性升高，超声显示的不均质-低回声斑块与急性脑梗死的发生有密切关系，超声发现颈动脉相关病变对早期干预和脑梗死的预防有重要意义。

Objective To explore the relationship between cerebral infarction and the formation and character of carotid plaque, and provide scientific basis for the prevention and treatment of cerebral infarction. Method 30 patients with acute cerebral infarction and 28 cases with no cerebral vascular disease ( the control group) were examined by color Doppler ultrasound, and their carotid vascu-lar morphology, vascular lumen stenosis or not and the degree, carotid intima-media thickness ( IMT) , plaque or not and its character were observed. Results (1) The comparison of luminal stenosis degree between the two groups:the ratio of moderate stenosis 50%~75% and severe stenosis>75% in cerebral infarction group is higher than that of the control group (P<0.05). (2) For IMT, there was no significant difference in cerebral infarction group and the control group (P>0.05). (3) The soft plaque and ulcer plaque oc-currence rate in cerebral infarction group is higher than that of the control group (P<0.05). Conclusion Carotid stenosis may lead to the increasing risk of acute cerebral infarction; as ultrasound shows, heterogeneity-low echo plaques have close relationship with the occurrence of acute cerebral infarction. Ultrasound detection of carotid artery related disease plays a vital role in the early intervention and prevention of cerebral infarction.
