摘　　要：目的探讨颈内动脉起始段狭窄患者的非特异性神经精神症状与脑梗塞的关系。方法运用彩色多普勒超声检测仪,选择颈内动脉起始段狭窄患者214例,其中狭窄<70%者145例;狭窄≥70%者69例。将214例患者因脑供血不足而出现的神经精神症状分为无症状组、轻度症状组、明显症状组、危险症状组,分析颈内动脉起始段狭窄和神经精神症状及脑梗塞三者之间的关系。结果随着颈内动脉起始段狭窄程度的逐渐加重,引起的神经精神症状也逐渐加重;出现非特异性症状的患者与出现危险症状的患者脑梗塞的发生率分别为6.0%、8.1%,两者之间差异无统计学意义(χ2=0.1821,P=0.670)。结论颈内动脉起始段狭窄患者的非特异性神经精神症状引起脑梗塞的风险不容忽视,应及早进行干预和治疗,以有效控制或延缓脑梗塞的发生。Objective To assess the relationship between subclinical neuropathic psychiatrical symptoms caused by stenosis of initial segment of carotid artery and cerebral artery infarction. Methods 214 patients were chose randomly according to the stenosis degree of initial segment of carotid artery measured by color Doppler ultrasound. 145 patients stenosis were lower than 70%, while 69 patients stenosis were higher than 70%. Meanwhile ,those patients were divided into four categories according to the neuro- pathic psychiatrical symptoms caused by insufficient cerebral blood supply：no symptom,mild symptoms,remarkable symptoms, dangerous symptoms. Results With the gradual increment of the stenosis degree of initial segment of carotid artery the neuropathic psychiatrical symptoms caused by stenosis aggravated correspondingly. It was similar that the percent of cerebral infarction in subclinical neuropathic psychiatrical symptoms groups with in the dangerous symptoms groups,and there is no significant difference be tween the two groups （X^2=0.1821, P=0.670）. Conclusions The risk of cerebral infarction caused by stenosis of initial segment of carotid artery when presented as subclinical neuropathic psychiatrical symptoms should not be neglected, and it should be intervene and treat earlier so that the occurrence of cerebral infarction would be control and prolong.
