摘要 目的:观察缺血性脑卒中患者踝臂指数(ABI)与颅内动脉狭窄程度的相关性,评价ABI对颅内动脉狭窄程度的预测价值。方法:对93例行脑血管造影的缺血性脑卒中患者进行ABI测量,并收集相关影响因素的资料。结果:颈动脉重度狭窄患者ABI显著降低(P<0.01),而正常、轻度中度狭窄患者的ABI无显著性差异;前后循环均狭窄患者ABI明显降低。ABI<0.9作为截断值预测重度颈动脉狭窄病变具有相对高的特异度(67.2%)和敏感度(82.8%)。结论:缺血性脑卒中患者ABI与颅内动脉狭窄严重程度显著负相关,ABI<0.90对预测脑动脉狭窄病变具有较高的特异度和敏感度。 Objective:To oberserve the relationship between ankle brachial index(ABI) and the extent of intracal artery stenosis and evaluate the usefulness of ABI to predict the extent of intracal artery stenosis in ischemic stroke patients. Methods:93 ischemic stroke patients with brain angiography were examined by ABI and influential factors evaluation were collected. Results:ABI reduced significantly (P〈0.001) in the patients with severe stenosis in carotid artery, there were no significant differences in ABI among the patients with no stenosis or slight midrange stenosis in carotid artery,and ABI reduced significantly when the anteroposterior circulation all stenosis. When ABI〈0.9,it had a relatively high specificity (67.2%) and sensitivity (82.8%) for predicting the presence of severe stenosis in carotid artery. Conclusion:In ischemic stroke patients,ABI is inversely and significantly associated with the intracal artery stenosis and ABI〈0.9 has a relatively high specificity and sensitivity for predicting the presence of carotid artery stenosis .
