摘要
目的观察正常人胸导管在脊柱T4～T12节段的解剖走行,并测量相关解剖学参数,为胸腔镜下胸椎前路手术安全处理胸导管提供依据。方法解剖30具正常成人尸体标本,观察胸导管在脊柱T4～T12节段的解剖走行,测量T4～T12各节段右侧肋骨头到胸导管右缘的长度,以此描述胸导管在T4～T12节段的走行。结果胸导管多于T12右膈脚处起自乳糜池,经膈主动脉裂孔入胸腔后纵隔后,在胸主动脉与奇静脉之间,形成向椎体左侧凸出的弯曲,沿脊柱胸段前面上行,在T5椎体水平越过主动脉后方由椎体右侧越过中线渐向左侧移行,在T4水平紧贴纵隔胸膜及椎体左前方垂直上行。结论胸导管在T4～T11节段上行过程中向椎体的左侧凸出,胸导管T7～T11段多为单根,走行固定,变异少。胸腔镜下胸椎前路手术时更容易在此节段安全处理胸导管。
Objective To observe the anatomical characteristics of normal thoracic duct and collect related anatomical parameters in the course of T4-12 spinal segments for providing an anatomical basis of anterior thoracic spinal approach for video assisted thoracoscopic surgery(VATS).MethodsAn anatomical study was performed on thirty normal adult cadavers to observe the anatomical characteristics and distribution of the thoracic duct in the course of T4-12 segments,and the distance from the right rib head to the righ...
