摘要
目的:为颈胸段脊柱(CTS)选择合理的手术入路提供解剖学依据。方法:在30具尸体标本上,观察胸骨颈静脉切迹(SJN)平面重要结构解剖及毗邻关系。结果:(1)70%的SJN水平向后对应的椎体水平为T2～T2/3。(2)70%的主动脉弓(AA)顶点位于T3椎体水平。63.33%的上腔静脉(SVC)起点位于T3椎体水平。AA顶点与SVC起点分别距椎体前正中线(PVM)的距离之间差异无统计学意义(P>0.05)。头臂干和左颈总动脉分别与PVM的夹角α为(31.58±1.02)°和β为(16.55±0.46)°,两者之间差异有统计学意义(P<0.05)。结论:熟悉胸骨颈静脉切迹、主动脉弓及其分支、和上腔静脉及其属支的相关解剖有助于在颈胸段脊柱前路手术中选择合理的手术入路。
Objective：To provide anatomic data for the optimal approach of cervicothoracic spine（CTS）. Methods： Anatomic features of the region of sternal jugular notch（SJN） were observed and analyzed on 30 adult cadavers. Results： For 70% specimens, SJN were at the level of T2-T2/3; for 70% specimens, the peak of aortic arch （AA） were at the level ofT3; for 63.33% specimens, the origin of superior vena cava （SVC） were at the level of T3. The difference of both distances between PVM and the peak of AA or the origin of SVC had no statistic significance （P〉0.05）. Angles between PVM and brachiocephalic trunk or left common carotid artery respectively was （31.58 ±1.02）° and （16.55 ±0.46）° ,with the significant difference among them （P〈0.05）. Conclusions： Anatomic relations among SJN, AA and SVC might be helpful for selecting the optimal approach of CTS.
