摘要
目的:研究颈动脉鞘和椎前筋膜的解剖关系,提高颈椎前路手术中对颈总动脉的安全性。方法:取福尔马林固定的教学用成人尸体标本22具,新鲜尸体6具,显露颈动脉鞘和椎前筋膜,观察椎前筋膜的层次、质地、向两侧的移行及其和颈动脉鞘的关系。结果:椎前筋膜浅层厚且致密,向椎体外侧直接延续移行到颈总动脉、颈内静脉前方,构成颈动脉鞘的前壁、内及外侧壁,在保持椎前筋膜浅层完整性的条件下,内外移动颈动脉鞘的活动度受到明显限制。结论:椎前筋膜是颈动脉鞘的主要组成部分,使颈动脉鞘相对固定,在颈椎前路手术中应避免用力牵拉。
Objective：To investigate the anatomic relationship between prevertebral fascia and carotid sheath and to guarantee the safety of the common carotid artery in anterior cervical approach.Method：22 embalmed cadavers and 6 fresh cadavers were dissected.All elements that were anterior to the cervical vertebra were removed to expose the carotid sheath and prevertebral fascia,layers and texture of which were observed.The transition laterally to prevertebral fascia and its relationship to carotid sheath was observed.Result：The superficial layer of prevertebral fascia which was thick and dense transited anteriorly to the carotid artery and jugular vein,consequently formed the anterior,medial and lateral wall of carotid sheath.Keeping the superficial layer of prevertebral fascia intact,moving of the carotid sheath both laterally and medially was significantly restricted,Conclusion：The superficial layer of prevertebral fascia is the main portion of the carotid sheath,which should avoid overtraction in the anterior cervical approach.
