Abstract:
Objective To study the association between leptomeningeal anastomosis (LMA) collateral circulation and cerebral infarction in patients with middle cerebral artery (MCA) M1-segment stenosis by observing the compensatory characteristics of LMA collateral circulation.Methods One hundred and fourteen MCA M1-segment stenosis patients were divided into cerebral infarction group (n=68) and cerebral infarction-free group (n=46).The hemilateral phenomenon of homolateral anterior cerebral artery (ACA) stenosis and posterior cerebral artery stenosis was assessed and its effect on the incidence of cerebral infarction was studied according to its magnetic resonance angiography.Results The ACA score and MCA stenosis severity were significantly different between cerebral infarction group and cerebral infarction-free group (P＜0.05).Multivariate logistic regression analysis showed that low ACA score and MCA M1-segment stenosis were two independent risk factors for cerebral infarction (OR =0.390,95％ CI:0.154-0.987;OR =2.421,95％CI:1.324-4.428,P＜0.01).Conclusion The incidence of cerebral infarction is low in MCA M1-segment stenosis patients with good ACA collateral circulation.
