Study On The Relationship Between The Measured Value Of Cervical Transverse Process Aperture Line And Atherosclerotic Plaque Formation In Intracranial Segment Of Vertebral Artery

Objective:To explore the relationship between the measured value of the transverse process diameter of each cervical spine and the formation of atherosclerotic plaque in the intracranial segment of the corresponding vertebral artery.Methods:Randomly extract images of patients who underwent CTA examination of the head and neck aortic arch in department of radiology,Affiliated Hospital of Chengde Medical College from November 2017 to June 2019,excluding patients with vascular malformations,running abnormalities,vertebral developmental deformities,and patients who have undergone vascular or vertebral surgery.There were 120 vertebral arteries,of which 60 had atherosclerotic plaques in the intracranial segment of the vertebral artery,and 60 do not had atherosclerotic plaques in the intracranial segment of the vertebral artery.These patients were divided into plaque group and non-plaque group.The patients were 47-80 years old,with an average age of 59.81±9.10 years,including 60 males and 60 females.Then I collected C6-C2 cervical transverse foramen(A total of 600 transverse foramens)aperture data of each vertebral artery,including: A :transverse diameter of transverse foramen),B:sagittal diameter of transverse foramen,C :transverse diameter of vertebral artery,D:sagittal diameter of the vertebral artery,then the ratio of the vertebral artery's transverse diameter to the transverse foramen's transverse diameter(C / A)and the vertebral artery's sagittal diameter to the transverse foramen's sagittal diameter(D / B)were calculated to evaluate the vertebral artery's proportion in the transverse foramen.Then A?B?C?D?C/A?D/B were compared between the two groups,and the differences were observed to infer whether there was a relationship between the size of the transverse foramen and the formation of atherosclerotic plaque in the intracranial segment of the vertebral artery.The case selection had been approved by the ethics committee of the affiliated hospital of Chengde Medical College.Results:1.The transverse diameter and sagittal diameter of each transverse foramen in the plaque group are smaller than that in the non-plaque group,and the difference is statistically significant.Among the transverse foramens,except for the transverse diameter,sagittal diameter of the plaque group C2 and the sagittal diameter of the non-plaque group C2,the diameter of the transverse foramens gradually increase from top to bottom.2.The transverse and sagittal diameters of the vertebral arteries in the plaque group are larger than those in the non-plaque group,and the difference is statistically significant.Among the vertebral arterial cross sections,the sagittal diameter of the vertebral artery gradually increase from top to bottom in the two groups.Among the transverse diameter of vertebral artery,the plaque group has the largest C4,and the non-plaque group has the largest C3.3.The ratio C/A of the vertebral artery transverse diameter to the transverse diameter of the transverse foramen and the ratio D/B of the sagittal diameter of the vertebral artery to the sagittal diameter of the transverse foramen in each vertebral body of the plaque group are both higher than that in the non-plaque group,and the difference is statistically significant.Conclusion:The diameter of the transverse foramen of the cervical spine is related to the formation of atherosclerotic plaques in the intracranial segment of the corresponding vertebral artery.The smaller area of the transverse foramen that the V2 segment of the vertebral artery passes through and bigger proportion of vertebral arteries in the transverse foramen will promote the formation of atherosclerotic plaques in the corresponding intracranial segment of the vertebral artery.
