A number of studies have investigated vertebral artery flow velocity. Because perfusion relates to the volume of blood flowing through the vessel, this parameter is of great importance when vertebral artery hemodynamics are investigated. We could not find any such Doppler studies in the literature, possibly because of known errors with previous techniques. New advanced color-coded duplex sonography has since been validated and may be used with confidence for volume flow investigations.
To use advanced color-coded duplex sonography to investigate volume flow through the vertebral arteries during cervical rotation, as well as before and after spinal manipulation therapy.
A randomized controlled study at a university hospital vascular laboratory.
Twenty university students.
Volume blood flow through the vertebral arteries does not change with cervical rotation or after spinal manipulation therapy.
This appears to be the first in vivo Doppler study on human vertebral artery volume blood flow. Our results indicate that in symptom-free subjects there is no change in vertebral artery perfusion during rotation in spite of significant changes in flow velocity. This finding, as well as the observed changes in flow velocity reported by others, may be explained by a positional change in the vertebral artery diameter. In addition, we have investigated volume blood flow in the vertebral arteries before or after spinal manipulation therapy but found no significant changes.
多项研究对椎动脉血流速度进行了调查。由于灌注与流经血管的血量相关，因此在研究椎动脉血流动力学时，该参数至关重要。我们在文献中未找到任何此类多普勒研究，可能是因为先前技术存在已知误差。此后，新的先进彩色编码双功超声已得到验证，可放心用于容积血流研究。
使用先进的彩色编码双功超声研究颈椎旋转期间以及脊柱手法治疗前后椎动脉的容积血流。
在大学医院血管实验室进行的一项随机对照研究。
20名大学生。
椎动脉的容积血流量在颈椎旋转或脊柱手法治疗后未发生变化。
这似乎是第一项关于人体椎动脉容积血流量的体内多普勒研究。我们的结果表明，在无症状受试者中，尽管流速有显著变化，但旋转期间椎动脉灌注无变化。这一发现以及其他人报告的观察到的流速变化，可能是由椎动脉直径的位置变化所解释。此外，我们研究了脊柱手法治疗前后椎动脉的容积血流量，但未发现显著变化。
