摘要
目的:探讨有利于术前选择脊柱颈胸交界段手术入路的颈胸段MRI测量方法。方法:随机抽取95例颈椎MRI片,测量胸骨上切迹向后水平延长至相应椎体前缘的距离(AO)和对应的椎体或椎间隙,同时测量胸骨上切迹向后上方至C7/T1椎间隙前缘中点的距离(BO),测量AB间的距离及两线之夹角(称为颈胸手术角)。结果:AO距离平均为50.40mm,BO距离平均50.97mm,AB距离平均为41.41mm,夹角平均为47.64°。胸骨上切迹相对应的椎体最常见的为T3椎体的上1/3,其次为T2/3椎间隙。结论:颈胸段手术入路的选择可结合患者脊柱颈胸段的MRI表现,判断颈胸结合部与胸骨上切迹以及胸骨角水平面的关系,估计常规的下颈椎低位前方入路或经仅劈胸骨柄的手术入路能否到达颈胸结合部的病灶,从而便于选择损伤最小、手术时间最短、手术并发症较少、利于患者康复的手术入路。
Objective:To discuss the relation of the MRI measurement in the cervicothoraic junction to the optimal operative approac h in the cervicothoracic spinal diseases.Method:The vertebral levels horizontal ly to the suprasternal notch(line AO),another line(line BO)from the suprasternal notch to the anteiror midpoint of the C7/T1intervertebral disc and the ang le co mposed of the two lines(∠AOB,called cervicothoracic angle,CTA)were drawn and de termined from95consecutive midsagittal cervicothoracic MRI studies.Result:The A O,BO,AB distance were50.40mm,50.97mm,41.41mm on the average.The superior third o f the T3vertebra was most frequently above the sternal notch.∠AOB was47.64degre es on the average.Conclusion:The midsagittal cervicothoracic MRI can identify no t only the thoracic levels above the suprasternl notch but also the possilbe pla te length as well,thus the most possible approach carrying less operative risk,n eeding shorter operative time,can be decided prior to surgery,which is conducive to the early recovery of the patients.
