摘要目的:探讨缺血性卒中患者踝肱指数(ABI)与颅内动脉粥样硬化的关系.方法:73例缺血性卒中患者,使用血管多普勒超声测量仪测定ABI,使用1.5 T磁共振成像系统进行头颅磁共振血管造影(MRA)对颅内动脉狭窄程度进行分级,分析缺血性卒中患者ABI与颅内动脉狭窄分级的相关性.结果:无颅内动脉狭窄者(n=38)ABI显著高于有颅内动脉狭窄者(n=35)(0.975±0.114对0.837±0.096,P<0.001),ABI与颅内动脉狭窄程度呈显著负相关性(r=-0.736,P=0.001).结论:ABI与颅内动脉粥样硬化狭窄程度呈负相关,可作为颅内动脉粥样硬化的初步筛查手段.

abstractsObjective:To investigate the correlation between ankle-brachial index(ABI)and intracranial atherosclerosis in patients with ischemic stroke.MetlaTds:qhe ABI of 73 patients with ischemic stroke were detected using vascular Doppler ultrasound;head magnetic resonance angiography(MkA)was performed using a 1.5 T magnetic resonance imahing system,and the extent of intracranial artery stenosis was graded.The correlation between ABI and the grade of intracranial artery stenosis in patieras with ischemic stroke was analyzed.Results:The ABI in patients without intracranial artery stenosis(n=38)was significantly higher than those with intracranial artery stenosis(n=35)(0.975±0.114 vs 0.837±0.096,P<0.001).The ABI was significantly negatively correlated with the extent of intracranial artery stenosis(r=-0.736,P=0.001).Conclusions:The ABI was negatively correlated with the extent of intracranial artery stcnosis.It can he used as a preliminary screening means of intracranial atherosclerosis.
