短暂性脑缺血发作与颅内外血管狭窄的关系

目的探讨短暂性脑缺血发作(TIA)与颅内外血管狭窄的关系。方法给68例TIA患者进行颈部B超、经颅多普勒(TCD)以及心脏超声检查,对其中56例有明显脑血管狭窄的患者进一步行数字减影血管造影(DSA)检查。结果56例行DSA检查的患者中,显示大脑中动脉狭窄(或闭塞)6例,颈内动脉狭窄(或闭塞)21例,锁骨下动脉狭窄8例,椎基底动脉狭窄(或闭塞)28例。大动脉狭窄性TIA44例,其中颈内动脉系统16例,椎基底动脉系统28例;栓塞性TIA18例,其中颈内动脉系统15例,椎基底动脉系统3例;腔隙性TIA4例;血管痉挛性TIA2例。结论TIA患者大多存在颅内外血管狭窄,其与TIA有密切关系。

Correlation between transient ischemic attack and intracranial or extracranial artery stenosis

Objective To investigate the relationship between transient ischemic attack(TIA) and intracranial or extracranial artery stenosis.Methods Digital subtraction angiography (DSA) was further used in 56 cases with cerebral artery stenosis from 68 TIA patients after examinations of B ultrasound of neck, transcranial color doppler(TCD) and cardiac ultrasound. Results 6 cases were shown stenosis or occlusion in middle cerebral arteries(MCA), 21 cases were shown stenosis or occlusion in arteria carotis interna,8 cases were shown stenosis in subclavian arteries and 28 cases were shown stenosis or occlusion in vertebral arteries or basal arteries. 44 cases with TIA were related to stenosis of large arteties, 16 cases of which were intracarotid TIA, and 28 cases were vertebrobasilar TIA; 18 cases were embotic TIA, 15 cases of which were intracarotid TIA, and 3 cases were vertebrobasilar TIA. 4 casea were lacunar TIA; and 2 cases were related to vascular spasm. Conclusions Most patients with TIA have cerebral artery stenosis.There is a positive correlation between TIA and intracranial or extracranial artery stenosis.
