| 目的 观察超声评估椎动脉走行变异（VA-CV）及血流动力学变化的价值。方法 纳入VA-CV患者（VA-CV）及非VA-CV患者（对照组）各41例，以超声检测椎动脉（VA）变异侧别、V1段起源位置、锁骨下动脉近段（PSCA）长度、VA进入横突孔位置、V2段管径、收缩期峰值血流速度（PSV）及舒张末期血流速度（EDV），分析超声评估VA-CV及相关血流动力学变化的价值。结果 于VA-CV组共检出49支变异VA，19支位于左侧、30支位于右侧，右侧多于左侧；其中17支（左侧16支、右侧1支）VA起源异常，左侧VA起源异常多于右侧（P<0.001），右侧VA多为低位起源（P<0.001）。VA-CV组右侧PSCA长度小于对照组（P<0.05），其变异VA多自C5-6（33/49，67.35%）横突孔进入椎间隙，且入孔位置越高，PSCA越短（P<0.05）。VA-CV组内左侧VA-CV患者V2段管径小于、EDV低于对照组（P均<0.05）。结论 超声可客观评价VA-CV及相关血流动力学变化。 |

| Objective To observe the value of ultrasonography for evaluating the anatomy and hemodynamic characteristics of vertebral artery course variation (VA-CV). Methods Totally 41 patients with VA-CV (VA-CV group) and 41 patients without VA-CV (control group) were enrolled. Lateral variation of vertebral artery (VA), the origin of V1 segment, the length of proximal subclavian artery (PSCA), the location of VA into the transverse foramen, the diameter of V2 segment, the peak systolic velocity (PSV) and the end-diastolic velocity (EDV) were evaluated with ultrasonography. The value of ultrasonography for evaluating VA-CV and relative hemodynamic changes were analyzed. Results Totally 49 variant VA were detected in VA-CV group, including 19 on the left and 30 on the right side, VA-CV on the right side was more often than on the left side. Seventeen (16 on the left and 1 on the right side) VA had abnormal origins, and abnormal VA origins on the left side were more than that on the right side (P<0.001). Meanwhile, VA origins of right VA-CV were mostly lower than that of the left side VA-CV (P<0.001). The length of right PSCA in VA-CA group was shorter than that in control group (P<0.05). More than half variant VA entered vertebral space from the transverse foramen of C5-6 (33/49, 67.35%), and the higher the entrance of transverse foramen, the shorter the PSCA (P<0.05). In VA-CV group, the diameter of V2 segment in left VA-CV patients was smaller than that in control group, while EDV in the former was lower than in the latter (both P<0.05). Conclusion Ultrasonography could be used to objectively evaluate VA-CV and relative hemodynamic changes. |
