Clinical application of color Doppler ultrasonography on diagnosing vertebral artery abnormality of the flying personnel with cervical vertigo

Objective To study the correlation between cervical vertigo and vertebral artery abnormality by analyzing the clinical application of color Doppler ultrasonography on flying personnel.Methods The ultrasound imaging and related data of 168 flying personnel's with cervical vertigo were reviewed and analyzed.Results There were 78 cases of vertebral artery abnormalities,including 9 cases of anomalous origin, 11 cases of unilateral or bilateral behavior abnormalities, 33cases of dysplasia (32 cases of unilateral or bilateral dysplasia and 1 case of complete occlusion) and 25cases of behavior abnormality plus dysplasia.Vertebral artery hemodynamics abnormality was found in 48 cases.Among vertebral artery abnormalities, 8 and 25 cases were respectively assessed as permanently or temporally grounding while the rest 45 were qualified.Conclusions Congenital vertebral artery abnormalities take high proportion in the flying personnel with cervical vertigo.Vertebral artery ultrasound examination would be helpful for diagnosing vertebral artery abnormalities at recruiting stage and furthermore for reducing grounding rate.It is suggested that to include vertebral artery ultrasound examination in flying cadets physical examination.
