Two-dimensional and color Doppler ultrasound analysis of vertebral artery in pilot cadets / 解放军医学杂志

ABSTRACT

Objective To investigate the development of vertebral artery in the 2010 enrolled pilot cadets, and provide a foundation for introducing vertebral artery ultrasound examination into inclusion criteria. Methods The ultrasound findings of the vertebral artery in 722 pilot cadets, including its origin, shape, diameter and hemodynamic patterns, were retrospectively reviewed by two-dimensional and color Doppler ultrasound. The proportion of its congenital dysplasia was calculated and summarized. Results Among the 722 pilot cadets, both the inner diameter of the initial segment (D1) and the intervertebral segment (D2) of left vertebral artery were wider than the right one (3.624±0.017mm vs 3.489±0.018mm, 3.623±0.018mm vs 3.438±0.019 mm, P0.05). Among 5 persons showed both abnormal origin and shape, there were 2 cases in whom there was also small caliber. Conclusions Multiple congenital dysplasia of vertebral artery was found in pilot cadets. The ultrasonography examination of vertebral artery should be included in the selection criteria for pilot cadet enrollment as early as possible.
