飞行员颈性眩晕与椎动脉先天发育异常的关系

目的探讨飞行员颈性眩晕与椎动脉先天发育异常之间的关系。方法利用二维超声及彩色多普勒超声回顾性分析71例颈性眩晕飞行员患者的椎动脉走行、内径及血流动力学变化等,总结颈性眩晕飞行员患者中椎动脉先天发育异常的比例。结果根据椎动脉异常的超声诊断标准,本组71例患者142条椎动脉中,85条椎动脉起始段清晰显示,显示率为59.9%(85/142),椎间段均清楚显示,显示率为100%;椎动脉纤细者20例,占28.2%(20/71),共包括21条椎动脉(左侧8条,右侧13条),其中1例为双侧椎动脉纤细,均为均匀性纤细;椎动脉走形变异22例,占31.0%(22/71),共包括椎动脉37条;同时存在椎动脉纤细和椎动脉走行异常者12例,占16.9%(12/71)。血流动力学参数异常者13例,28例患者合并颈椎X线片改变;椎动脉纤细者左右侧椎动脉内径、收缩期峰值流速(Vmax)及血流量之间差异无统计学意义。结论椎动脉发育异常是飞行员颈性眩晕的主要原因之一,椎动脉超声检查可作为招飞检查项目。

Relationship between congenital dysplasia of vertebral artery and cervical vertigo of pilot

Objective To explore the relationship between congenital dysplasia of vertebral artery and cervical vertigo of pilot.MethodsThe data of 71 pilots with cervical vertigo were retrospectively analyzed including the course,inner diameter and hemodynamic patterns of vertebral artery,as detected with two-dimensional and color Doppler ultrasound,and the proportion of congenital dysplasia of vertebral artery was surveyed in pilots with cervical vertigo.ResultsAccording to the ultrasound diagnostic criteria of abnor...
