目的应用MRI及MRA探讨基底动脉走行、桥脑梗死之间的关系。方法应用MRI和MRA观察1662例不同年龄患者有无椎动脉优势与迂曲,有无基底动脉迂曲及迂曲分度,有无桥脑梗死,分析椎动脉优势与迂曲,椎动脉迂曲与基底动脉迂曲,基底动脉迂曲分度、桥脑梗死与年龄之间的关系。结果椎动脉优势与迂曲相关(χ~2=62.294,P=0.000);椎动脉迂曲与基底动脉迂曲相关(χ~2=199.55,P=0.000);不同年龄与桥脑梗死相关(χ~2=117.829,P=0.000),相关系数r=0.257;基底动脉迂曲分度与桥脑梗死存在相关性(χ~2=338.281,P=0.000),相关系数r=0.411;不同年龄阶段与基底动脉迂曲分度存在相关性(χ~2=123.852,P=0.000),相关系数r=0.263。结论基底动脉迂曲程度、患者年龄与桥脑梗死存在相关性,这种相关性是多种因素共同作用的结果。
Objective To explore the relationship between basilar artery walking and cerebral infarction by MRI and MRA. Methods MRI and MRA were used to observe the superiority and tortuosity of vertebral artery in 1662 patients of different ages, whether tortuous or tortuous basilar artery with or without cerebral infarction, superiority and tortuosity of vertebral artery, tortuous vertebral artery and tortuous basilar artery, Basal artery tortuosity index, the relationship between cerebral infarction and age. Results The superiority of vertebral artery was related to tortuosity (χ ~ 2 = 62.294, P = 0.000). The tortuosity of vertebral artery was correlated with tortuous basilar artery (χ ~ 2 = 199.55, P = 0.000) = 117.829, P = 0.000). The correlation coefficient r = 0.257. There was a correlation between tortuous degree of basilar artery and pontine infarction (χ ~ 2 = 338.281, P = 0.000) The tortuous index was correlated (χ ~ 2 = 123.852, P = 0.000), and the correlation coefficient was 0.263. Conclusions The degree of tortuosity in the basilar artery and the age of patients are related to pontine infarction. The correlation is the result of many factors.
