ABSTRACT
Objective To study the application of cervical vertebral artery CT angiography(CTA) preoperatively in the screw setting of upper cervical spine.Methods The data of 170 patients who underwent upper cervical spine surgery from January 2014 to December 2015 in our hospital were retrospectively analyzed,of whom 80 cases with typeⅡodontoid fractures,90 cases with atlantoaxial dislocation;20 cases were operated with occipitocervical fusion,150 cases treated with atlantoaxial fusion.Seventy-eight cases were examinated by cervical vertebral artery CTA before sugery(observation group) but the other 92 cases(control group).The rate of the vertebral arterial lesion between the two groups were compared.Results Six cases with vertebral artery injury in control group,the incidence of arterial injury was 7%;unilateral vertebral artery was found in 3 cases,small congenital development of left cervical vertebral artery in 5 case,abnormal branch in 5 cases.The rate of dysplasia was 17%,and the rate of vertebral artery injury was 0.The rate of vertebral artery injury in control group was higher than observation group,the difference was significant(P<0.05).Conclusion Vertebral artery CTA examination preoperatively may become a routine examination,in order to make the operator carefully evaluate the relationship between the vertebral artery with atlantoaxial vertebral,choose the accurate screw-setting and avoid the vertebral artery injury in the upper cervical spine surgery.
