糖尿病合并脑梗死患者颈动脉超声46例分析

目的探讨糖尿病合并脑梗死惠者颈动脉超声的价值和意义。方法采用彩色多普勒显像仪对46例糖尿病合并脑梗死（DMCI）、40例非糖尿病脑梗死（CINDM）和42例非脑梗死糖尿病（DMNCI）患者进行颈动脉超声检测。结果DMCI组颈动脉内膜中层厚度（IMT），颈动脉不稳定斑块率和颈动脉狭窄程度，分别与CINDM组和DMNCI组比较，均有明显差异（P〈0．01，P〈0.05，P〈0.01）。结论糖尿病合并脑梗死患者的颈动脉粥样硬化斑块形成，内膜增厚及颈动脉狭窄是造成脑梗死的主要原因，颈动脉超声为糖尿病患者可能造成脑梗死提供早期预测。

Analysis of forty-six cases about carostid artery ultrasonography of the type 2 diabetes mellitus with cerebral infarction

Objective To explore the diagnosic value of carotic artery colour Doppler ultrasonography in the type 2 diabetes mellitus(DM) with cerebral infarction.Methods Fourty-six patients with diabetes mellitus with cerebral infarction(DMCI),40 patients with cerebral infarction not with diabetes mellitus(CINDM),42 patients with diabetes mellitus not with cerebral infarction(DMNCI) accepted the examnation of carotid artery colour Dopper ultrasonography.Results Compared with those in CINDM and DMNCI groups,the thickness of carotid artery intima-media thickness(IMT),the occurrence rates of carotid artery instability plapues and the carotid artery stenosis extent in DMCI group were significant difference(P<0.01,P<0.05,P<0.01,respectively).Conclusion Thickening of carotid artery IMT,the formation of atheromatous plaque and carotid artery stenosis in DMCI patients are correlated with cerebral infarction.Carotid artery colour Doppler ultrasonography can predict the possibility of cerebral infarction in DM patients.
