椎-基底动脉供血不足性眩晕与颈椎不稳

Correlation between vertigo of vertebrobasilar insufficiency and cervical vertebra instability

目的:探讨椎-基底动脉供血不足(VBI)眩晕与颈椎不稳之间的关系方法:对2000/2002门诊和住院的84例VBI患者和30例健康志愿进行颈椎X线检查,在过伸过屈位X片上测量椎体间角度位移和水位移,在自然侧位X片上记录颈椎曲线。结果:VBI组有68例(81%)共74个节段有颈椎不稳,其中C5～619C3～416例,C2～3,C6～7各1例;正常对照组有4例(13%)共4个节段颈椎不稳,其中C4～52例,C3～4,C5～6各1例。两组颈椎不稳例数比较检验差异存在非常显著性意义(χ2=43.44,P<0.01)。VBI组颈椎线异常39例(46%),正常对照组颈椎曲线异常4例(13%),两组比χ2检验差异有非常显著性意义(χ2=10.31,P<0.01)。结论:VBI眩晕与颈椎不稳密切相关,颈椎不稳很可能是导致临床眩晕反复发作的原因之一。

AIM:To investigate the correlation between vertigo of vertebrobasilar insufficiency (VBI) and cervical vertebral instability. METHODS:Cervical vertebral radiographs were conducted in 84 inpatients and outpatients with VBI during the period from 2000 to 2002 and 30 healthy volunteers.The two groups were measured by the vertebrae angular and horizontal displacement in over extension and over flexion position as well as the cervical vertebrae curvature in natural lateral position. RESUITS:There were 74 segments of instable cervical vertebrae in 68(81%) cases of the VBI group.Among those, there were 19 cases of C5～6, 16 cases of C3～4, 1 case of C2～3 and 1 case of C6～7. There were 4 segments in 4(13.4%) cases of the control group, including 2 cases of C4～5, 1 case of C3～4 and 1 case of C5～6. The differences between the cases of vertebra instability in VBI patients and health controls had statistical significance(χ2=43.44,P< 0.01).Thirty nine (46.4%) cases of the VBI group and 4(13.3%) cases of the control group had abnormal cervical vertebrae curvature, with the statistically significant difference (χ2=10.31,P< 0.01). CONCLUSIONS:There is a high correlation between VBI and cervical vertebrae instability. The latter might be one of the causes of the repeat attack of VBI.
