椎动脉病变节段与颈性眩晕发病的关系研究

目的：探讨椎动脉病变节段与颈性眩晕发病的关系。方法：对纳入研究的500例患者进行详细的体格检查、X线摄片及TCD检查,统计分析患者年龄与性别、病变节段与性别、病变节段与致病因素、病变节段与年龄、致病因素与年龄之间的关系。结果：①各年龄段患者性别构成比的差异有统计学意义（2χ=15.242,P=0.001）,30岁以上患者中女性多于男性。②各病变节段性别构成比的差异无统计学意义（2χ=5.501,P=0.139）,第3段的患者比例明显高于其他节段。③各病变节段致病因素的构成比有差异（2χ=279.733,P=0.000）,病变节段与致病因素间有关联性（r=0.435）。④各病变节段年龄构成比的差异有统计学意义（2χ=69.239,P=0.000）。经2χ分割（校正α=0.008）,第3段与第1段、第2段、第4段的差异均有统计学意义（2χ=10.257,P=0.006;2χ=44.890,P=0.000;2χ=43.919,P=0.000）,其余各节段间年龄构成比的差异均无统计学意义（P=0.083）。⑤不同年龄段患者致病因素构成比的差异有统计学意义（2χ=74.456,P=0.000）,发病年龄与致病因素有关联性（r=0.265）。结论：椎动脉病变节段与颈性眩晕的发病具有关联性。

Research on the relation between pathogenic segment of the vertebral artery and cervical vertigo

Objective：To explore the relation between pathogenic segment of the vertebral artery and cervical vertigo.Methods：500 patients undergone physical examination,X-ray examination and TCD examination.The patients＇ age,sexuality,pathogenic segment and etiological factors were documented and the correlation of these factors were analyzed.Results：①The difference of sex constituent ratio was significant between different age stage（χ2=15.242,P=0.001）.More women than men were found in patients older than 30 years.②The difference of sex constituent ratio between different pathogenic segments of the vertebral artery was not statistically significant（χ2=5.501,P=0.139）.The highest incidence was found in the third segment of the vertebral artery.③Constituent ratio of etiological factors was significantly different between different pathogenic segments（χ2=279.733,P=0.000）and relevance presented between pathogenic segment and etiological factor（r=0.435）.④There was statistical difference of age constituent ratio between pathogenic segments（χ2=69.239,P=0.000）.There was statistical difference of age constituent ratio between the third segment and other segment（χ2=10.257,P=0.006;χ2=44.890,P=0.000;χ2=43.919,P=0.000） and the differences of age constituent ratio between the first,second and fourth segment were not statistically significant（P=0.083）.⑤There was statistical difference of constituent ratio of etiological factors between different age stage（χ2=74.456,P=0.000）and relevance appeared between age of onset and etiological factors（r=0.265）.Conclusion：Pathogenic segment of the vertebral artery has close relation with cervical vertigo.
