摘　　要：目的探讨椎基底动脉系统(VBAs)几何结构与基底动脉(BA)斑块之间的关系。方法收集110例患者的高分辨率磁共振血管壁成像(HRMR-VWI)资料。按VBAs几何结构分为4型:行走型、音叉型、拉姆达型、无汇合型。按椎动脉(VA)颅内段血管弯曲次数分为多弯曲型和寡弯曲型。HRMR-VWI用于BA斑块评估,用logistic回归分析确定VBAs几何结构类型与BA斑块间关系。结果110例患者,包括行走型28例(斑块21例),音叉型29例(斑块9例),拉姆达型34例(斑块23例),无汇合型19例(斑块14例)。组间差异有统计学意义(P<0.05),行走型比值比(OR)最高。多弯曲型35例(斑块29例),寡弯曲型75例(斑块38例),组间差异有统计学意义(P<0.05)。结论VBAs行走型、拉姆达型、无汇合型几何结构与BA斑块存在相关性,多弯曲型VA结构中BA斑块更常见。Objective To investigate the relationship between geometry of vertebrobasilar artery system(VBAs)and basilar artery(BA)plaque.Methods High-resolution magnetic resonance vessel wall imaging(HRMR-VWI)data were collected from 110 patients.According to the geometry of VBAs,all HRMR-VWI data were divided into four types,including walking type,tuning fork type,lambda type,and no confluence type.All data were divided into multi-bending type and oligo-bending type based on the numbers of bending of intracranial vertebral artery(VA)segment.BA plaque was assessed via HRMR-VWI.Logistic regression analysis were used to determine the relationship between the geometry type of VBAs and BA plaque.Results Of 110 patients,there were 28 cases with walking type(21 cases with plaque),29 cases with tuning fork type(9 cases with plaque),34 cases with lambda type(23 cases with plaque),19 cases with no confluence type(14 cases with plaque),and there were statistically significant differences in geometry of VBAs types among these four groups(P<0.05).The walking type had the highest odds ratio(OR).There were 35 cases with multi-bending type(29 cases with plaque),and 75 cases with oligo-bending type(38 cases with plaque),and there were statistically significant differences in numbers of bending of intracranial VA segment(P<0.05).Conclusion The walking type,lambda type,no confluence type of geometry of VBAs can be associated with BA plaque.BA plaque is more common in multi-bending type VA structures.
