摘　　要：目的探讨腔隙性脑梗塞与颅内脑动脉狭窄的关系。方法412例腔隙性脑梗塞患者均行经颅多普勒(TCD)检测,发现颅内动脉狭窄后进一步行磁共振血管造影(MRA)检查确诊。结果MRA检查发现颅内动脉狭窄127例。结论腔隙性脑梗塞患者颅内脑动脉狭窄发生率较高,推测其是腔隙性脑梗塞的重要病因。对腔隙性脑梗塞患者应重视检测可能存在的颅内脑动脉狭窄。Objective To study the correlation between lacunar cerebral infarction and cerebral arterial stenosis. Methods 412 patients with lacunar cerebral infarction confirmed by CT or/and MRI were examined using transcranial Doppler （TCD）. Of them, 132 cases after TCD detection were further examined using magnetic resonance angiography （MRA）. Result Out of 412 patients with lacunar cerebral infarction,127 cases were affirmatively confirmed by MRA to have cerebral artery stenosis. Conclusion The cerebral artery stenosis incurs at a higher rate in patients with lacunar cerebral infarction. Cerebral artery stenosis may play an important role in the process of lacunar cerebral infarction.
