Correlation Between Ankle-Brachial Index and Intracranial Atherosclerosis in Patients with Ischemic Stroke / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the correlation between ankle-brachial index(ABI)and intracranial atherosclerosis in patients with ischemic stroke.MetlaTdsqhe 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.
