Results The fibrous sheath like structures derived from periosteal tissues of cervical vertebra, transverse process and uncus process were observed to enwrap vertebral artery, vein and spinal nerve root. 结果延续自颈椎、横突孔、关节突等骨膜组织形成明显的纤维鞘膜样结构,将椎动脉、椎静脉及神经根包裹在内。
The tube of vertebral basilar vein located at the posterior center of the vertebral body. 椎基底静脉管均位于椎体后中央区。
The width of anterior internal vertebral vein was measured in the patients whose veins were all be seen. 选择椎管内静脉显示良好者测量各段椎管内前静脉的宽度。
The eight indexes of hemorheology, flow volume of vertebral artery on the broken side, inside diameter of vein and average bloodstream velocity were observed with HP-1000 color doppler ultrasonic diagnosis apparatus and LING-100 blood viscosity meter. 利用HP-1000型彩色多普勒超声诊断仪和LING-100血液比黏度计分别观察其治疗前后血液流变学8项指标、患侧椎动脉血流量、血流管径和平均血流速度的变化。
