经颅多谱勒超声检测脑梗塞患者颅内动脉狭窄

TRANSCRANIAL DOPPLER DETECTION OF INTRACRANIAL ARTERIAL STENOSIS IN PATIENTS WITH INFARCTION

为了解脑梗塞患者颅内动脉狭窄情况并初步探讨其在脑梗塞发病机制中的作用,用经颇多谱勒超声检查217例脑梗塞患者.发现颅内动脉狭窄93例,占42.9%,其中颈内动脉系狭窄97处(78例),椎基动脉系狭窄31处(23例),中度以上狭窄占70.3%;颈内动脉终末段和/或大脑中动脉狭窄程度不同(轻、中、重)与相应支配区脑梗塞分布(皮层及皮层下梗塞、深部梗塞)之间无显著差异.结果提示脑梗塞患者颅内动脉狭窄分布广泛且狭窄程度高;狭窄可能在脑栓塞及脑血栓形成机制上发挥作用.

To explore the intracranial arterial stenosis in patients with infarction, 217 patients with infarction were examined by transcranial doppler ultrasound. The stenotic lesions in 93 patients (42.9%) were found in the intracranial arteries, 97 stenosis (78 patients) in the internal carotid arteries and 31 stenosis (23 patients) in the vertebrobasilar arteries. 70.3% lesions led to moderate and severe stenosis. No significant difference between degree (mild、 moderate and severe) of the stenosis and distribution of infarcts (cortical and subcortical 、deep) . It indicated that stenosis were extensive and mre severe, and might cause both cerebral thrombosis and embolization.
