下咽部及颈段食管后壁弧形波浪状生理性压迹的研究

STUDY ON ARC AND WAVELIKE IMPRESSION OF ESOPHAGUS IN LOWER PHARYNGEAL AND CERVICAL PART

为研究钡餐检查时下咽部及颈段食管后壁出现的弧形波浪状压迹形成的机制，局部解剖观察了３０具尸体颈部标本，并与颈部健康者的３００例Ｘ线片作了对照分析。作者认为此压迹的形成系颈椎、椎间盘、前纵韧带压迫下咽部及颈段食管后壁所致，颈椎前缘增生时，此压迹更加明显。

The forming mechanism of arc and wavelike impression on lower pharyngeal and cervical part of esophagus was studied by barium meal examination. Observed 30 postmortem specimens and contrasted analysis with 300 cases of roentgenogram in health man,the authors considered that the cervical vertebral intervertebral discus and anterior longitudinal ligament oppress the retro-esophagus wall to form the impression. When the cervical anterior margin proliferate, the impression is superior to the non-proliferation.
