Vertebral artery hypoplasia (VAH) may be defined as VA flow volume below approximately 30-40 mL/min using color duplex sonography. The aim of this study was to evaluate the effect of VAH on internal carotid artery (ICA) flow volume and cerebral blood flow (CBF) volume.
In this study, 17 patients with VAH and 20 control subjects with normal VA flow volume were enrolled. The patients and control subjects were 50-75 years aged. The ICA and VA flow volumes were determined by using color duplex sonography. The ICA and CBF volumes of patients with VAH were compared with control group flow volumes.
There was no statistically significant difference in flow volumes of right, left and sum of both ICA between VAH and control group. However, CBF volume was lower in patient with VAH than control group.
Evaluation of CBF using color duplex sonography is noninvasive and easily applicable to all patients and provides valuable diagnostic data. To the best of our knowledge, this is the first study demonstrating lower CBFV and normal ICA flow volume in patients with VAH.
椎动脉发育不全（VAH）可定义为使用彩色双功超声检查时椎动脉血流量低于约30 - 40毫升/分钟。本研究的目的是评估VAH对颈内动脉（ICA）血流量和脑血流量（CBF）的影响。
本研究纳入了17例VAH患者和20例椎动脉血流量正常的对照受试者。患者和对照受试者年龄在50 - 75岁之间。使用彩色双功超声检查确定ICA和VA血流量。将VAH患者的ICA和CBF量与对照组的血流量进行比较。
VAH组与对照组之间右侧、左侧及双侧ICA血流量总和无统计学显著差异。然而，VAH患者的CBF量低于对照组。
使用彩色双功超声检查评估CBF是非侵入性的，易于应用于所有患者，并提供有价值的诊断数据。据我们所知，这是第一项证明VAH患者CBFV降低而ICA血流量正常的研究。
