摘　　要：目的探讨基于颅颈部CTA(CT Angiography)再处理对椎动脉(Vertebral Artery,VA)颅内段的影像解剖学研究。方法回顾性分析蚌埠医学院第二附属医院2020年5月至2021年8月符合纳入标准的行头颈部CTA检查成人的250人,运用颅脑三维血管重建技术对椎动脉及颅骨的重建显示,测量两侧椎动脉颅内段直径、长度及偏移度(Bending Length,BL)。结果基于Philips或3Dslicer软件对头颈部CTA进行三维重建出椎动脉的形态走形并可进行解剖测量;测得左侧椎动脉直径、长度及偏移度分别为:(3.33±0.68)mm、(3.89±0.63)cm、(5.64±3.42)mm;右侧椎动脉直径、长度及偏移度分别为:(3.07±0.69)mm、(3.92±0.59)cm、(4.99±3.44)mm,左右侧椎动脉偏移度及直径比较,差异具有统计学意义(P<0.05),左侧椎动脉直径及偏移度的均值较右侧的大;男性右侧椎动脉的直径、偏移度和长度:(3.14±0.67)mm、(4.98±3.37)mm、(3.99±0.52)cm;女性右侧椎动脉的直径、偏移度和长度:(2.98±0.71)mm、(4.97±3.56)mm、(3.83±0.65)cm,右侧椎动脉的长度在性别方面相比较差异具有统计学意义(P<0.05),而左侧椎动脉的直径、长度、偏移度在性别方面比较差异均不具有统计学意义(P>0.05);左右侧椎动脉的直径、长度及偏移度在年龄比较差异均不具有统计学意义(P>0.05)。结论基于头颈部CTA再处理可重建出椎动脉并可用于解剖测量;椎动脉的直径及偏移度左右侧差异显著,而椎动脉在性别及年龄方面比较无明显差异,为椎动脉的影像解剖学研究奠定了基础。Objective To investigate the imaging anatomy of intracranial Vertebral Artery(VA)in vertebral vertebral region based on CTA(CT Angiography)reprocessing.Methods A total of 250 subjects who met the inclusion criteria and underwent head and neck CTA examination in the Second Affiliated Hospital of Bengbu Medical College from May 2020 to August 2021 were retrospectively analyzed.The vertebral artery and skull reconstruction showed by cranial three-dimensional vascular reconstruction technique,and the diameter,Length and BL of intracranial segments of the vertebral arteries on both sides were measured.Results Using Philips or 3Dslicer software,3D reconstruction of CTA in the head and neck was performed to obtain the shape of vertebral artery and anatomical measurements could be made.The diameter,length and deviation of the left vertebral artery were(3.33±0.68)mm,(3.89±0.63)cm and(5.64±3.42)mm,respectively.The diameter,length and deviation of the right vertebral artery were(3.07±0.69)mm,(3.92±0.59)cm and(4.99±3.44)mm,respectively.Compared with the left and right vertebral artery diameter and deviation,the difference was statistically significant(P<0.05).The mean values of the left vertebral artery diameter and deviation were larger than that of the right vertebral artery.The diameter,deviation and length of right vertebral artery in male were(3.14±0.67)mm,(4.98±3.37)mm,(3.99±0.52)cm;Diameter,deviation,length of right vertebral artery in women:(2.98±0.71)mm,(4.97±3.56)mm,(3.83±0.65)cm,the length of the right vertebral artery had statistical significance in gender(P<0.05),while the diameter,length and deviation of the left vertebral artery had no statistical significance in gender(P>0.05).There were no significant differences in the diameter,length and deviation of the left and right vertebral arteries at different ages(P>0.05).Conclusion The vertebral artery can be reconstructed and used for anatomic measurement based on CTA reprocessing in the head and neck.There were significant differences in vertebral ar
