摘　　要：目的探讨脑桥梗死部位与基底动脉狭窄、弯曲的关系。方法回顾性发析2009年1月～2012年10月在本院神经科住院治疗新鲜脑桥梗死患者118例及前循环脑梗死105例(所有病例有头颅MRI及颅内外动脉CT血管成像(CTA)检查)。将脑桥梗死组设为A组:梗死位于脑桥中线一侧;B组:梗死部位位于脑桥中线两侧。脑桥梗死两组与基底动脉狭窄、弯曲作相关性统计分析。同时比较脑桥梗死组与前循环脑梗死组的基底动脉狭窄、弯曲发生率。结果 118例脑桥梗死中A组78例:基底动脉狭窄6例(7.69%),基底动脉2级弯曲60例(76.92%);B组40例:基底动脉狭窄或闭塞40例(100%),基底动脉2级弯曲32例(80%)。105例前循环脑梗死组中基底动脉狭窄5例(4.76%);基底动脉2级以上弯曲15例(14.29%)。①脑桥梗死A、B两组基底动脉狭窄或闭塞发生率有显著性差异(χ2=94.72,P=0.00)。脑桥梗死A、B两组基底动脉弯曲度无明显差异(χ2=0.146,P=0.703)。②脑桥梗死组与前循环梗死组的基底动脉狭窄、弯曲比较有明显差异(χ2=38.27、90.27,P=0.00、0.00)。结论脑桥梗死部位与基底动脉狭窄或闭塞、弯曲有关。Objective To investigate the correlation between the location of infarctions in pontine and stenosis or tortuosity of busilar artery. Methods A retrospective analysis of treatment was carried out from January, 2009 to October, 2012 in the department of neurology in 118 patients with acute pontine infarction and 105 patients with cerebral carotid artery infarction. All cases were examined by MRI and intracranial and extracranial artery CT angiography （CTA）. The patients were divided into two groups. Group A： Located on one side of the center line of pontine infarction; Group B： Located on both sides of the midline pontine infarction. The statistical analysis was given about the correlation between the infarctions in pontine and stenosis or tortuosity of busilar artery. The occurrent rates of stenosis or tortuosity, of busilar artery were compared between groups of infarctions in pontine and groups of cerebral carotid artery infarction. Results In all 118 patients with acute pontine infarction, 78 cases in group A： 6 cases （7.69%） have stenosis of basilar artery while 60 cases （76.92%） basilar artery 2 bent; 40 cases in group B： 40 cases （100%） have basilar artery stenosis or occlusion while 32 cases （80%） basilar artery 2 bent. In all 105 patients with cerebral carotid artery infarction, 5 cases （4.76%） have stenosis of basilar artery while 15 cases（14.29%） basilar artery 2 bent.①The occurrent rates of basilar artery stenosis in the two groups （A,B） make a big difference （χ^2=94.72,P =0.00）. Basilar artery tortuosity in the two groups （A,B） makes no difference （χ^2=0.146,P = 0.703）. ②The occurrent rates of basilar artery stenosis and tortuosity in the two groups （groups of infarctions in pontine and groups of cerebral carotid artery infarction） make a big difference （χ^2=38.27,90.27,P=0.00,0.00）. Conclusion There is significant correlation between the location of infarctions in pontine and stenosis or tortuosity of busilar artery.
