X线平片分析寰椎后弓椎动脉沟环与颈性眩晕的关系

目的探讨寰椎后弓椎动脉沟环与颈性眩晕的关系。方法通过收集广东省东莞市塘厦医院2008-08～2009-09 800例颈椎摄片中,选出发现有寰椎后弓椎动脉沟环的63例颈椎平片进行回顾性分析。结果 63例患者中,椎动脉沟环合并颈椎退行性变者21例(33.3%)。Ⅰ型36例,占57.1%;Ⅱ型14例,占22.2%,其中Ⅱa型5例,Ⅱb型9例;Ⅲ型13例,占20.6%。结论寰椎后弓椎动脉沟环的存在,在头颈部的旋转或屈伸运动时,可引起椎动脉痉挛或狭窄,导致椎基底动脉供血不足,从而出现间歇性眩晕有密切临床意义。

X-ray analysis of the relationship of atlas posterior arch vertebral arter y groove ring with cervical vertigo

Objective: To study the relationship of atlas posterior arch vertebral artery groove ring with cervical vertigo.Methods Collected 800 cases of cervical spine radiography in our hospital from August 2008 to September 2009,from which 63 cases were found the atlas posterior arch vertebral artery groove ring,these cases were retrospective analysis.Results In these cases,atlas posterior arch vertebral artery groove ring combined cervical spine degeneration in 21 cases(33.3%).TypeⅠ 36 cases,accounting for 57.1%;type Ⅱ 14 cases,accounting for 22.2%,of which 5 cases Ⅱa,Ⅱb 9 cases;type Ⅲ 13 cases,accounting for 20.6%.Conclusion Atlas posterior arch vertebral artery groove ring,which could cause vertebral artery spasm or stenosis and then result in vertebrobasilar insufficiency,which causing intermittent vertigo have a certain relationship.
