【摘要】：目的探讨人食管壁内血管和神经的分布特点及两者之间的关系。方法幼年尸体标本14例和成人标本4例,共计18例,采用硅胶血管灌注和再改良Sihler神经染色法相结合来显示人食管壁内血管及神经。结果人食管壁内血管整体分布以胸下段及腹段较密集,而颈段和胸上段相对较稀疏,整体前壁内血管较后壁内稀疏,壁内血管的细小分支间形成广泛的网状吻合。人食管壁内神经整体分布以腹段分布最稀疏,胸段壁内神经分布最多密集,但颈胸段壁内神经均衡分布,颈段上部可与来自于咽丛的神经分支形成吻合,食管壁内神经形成网状环路吻合。食管壁内血管与神经之间无明显的伴行关系。结论人食管壁内血管和神经分布均呈现网状吻合,但两者之间无明显伴行关系。
[Abstract]:Objective to investigate the distribution of blood vessels and nerves in the wall of human feeding duct and the relationship between them.Methods 14 juvenile cadavers and 4 adult cadavers (18 cases) were used to display the blood vessels and nerves in the wall of human esophagus by using silica gel perfusion and modified Sihler nerve staining.Results the overall distribution of the vessels in the wall of the human esophagus was denser in the lower thoracic segment and the ventral segment, but in the cervical segment and the upper thoracic segment, the whole anterior wall was sparser than that in the posterior wall, and the small branches of the intramural vessels formed extensive reticular anastomosis.The distribution of the nerves in the wall of the human feeding duct was the most sparse in the ventral segment and the most dense in the thoracic segment. However, the distribution of the nerve in the wall of the cervical and thoracic segments was balanced, and the upper part of the neck could coincide with the branch of the nerve from the pharyngeal plexus.The nerve in the wall of the esophagus was anastomosed with a reticular loop.There was no obvious concomitant relationship between the vessels and nerves in the wall of the esophagus.Conclusion the distribution of blood vessels and nerves in the wall of human esophagus is reticular anastomosis, but there is no obvious concomitant relationship between them.
