摘要： 目的分析比较高位脊髓损伤患者不同体位下大脑中动脉(MCA)血流动力学变化特征。方法采用经颅彩色多普勒超声(TCCD)技术,对48例高位脊髓损伤的患者分别于平卧位、斜立位 (30°、60°、80°)检测MCA的峰值流速(PSV)、舒张期末流速(EDV)及平均流速(MV)。结果斜立30°与平卧位比较PSV无显著性差异(P>0.05),EDV、MV有非常显著性差异(P<0.01)。斜立60°、80°与平卧位所测PSV、EDV、MV均有非常显著性差异(P<0.01)。结论脊髓损伤患者的体位变化影响MCA血流动力学的变化。

Abstract: ObjectiveTo study the speciality of hemodynamics in middle cerebral artery(MCA) by means of transcranial color Doppler ultrasound(TCCD) at different tilting angles in patients with cervical and thoracic spinal cord injury.Methods48 patients with spinal cord injury were involved. The velocity of peak systolic(PSV), end diastolic(EDV) and mean velocity(MV) of MCA on the tiltable at 0°,30°,60°,80° were measured.ResultsThere was no significant difference in PSV between 0°and 30°(P>0.05), while EDV and MV showed very significant (P<0.01)from 0°to 30°,60°and 80° position. From 0°to 60°,80°,there were differences not only at EDV and MV, but also PSV(P<0.01).ConclusionThe velocities of MCA were changed at different tilting angles in the patients with spinal cord injury.
