Abstract:

Objective To explore the distribution characteristics and relationship between the arteries and nerves in human esophageal wall.Methods Eighteen cadavers (14 Childhood cadavers and adult 4 cadavers) were used in this study. The silicone vascular perfusion and remodified Sihler’s staining technique were combined to show the intravascular and intramural nerves of the human esophageal wall. Results The vascular disbribution of the cervical and upper thoracic esophagus was less than the lower thoracic and abdominal esophagus. The vascular distribution of the anterior wall was less than the posterior wall. The branches of the arteries formed anastomosis with each other. The nerve distribution of the human esophageal wall was more in thoracic esophagus, and less in abdominal esophagus. The nerve distributions were similar in thoracic and cervical esophagus. Some nerves in upper part of the cervical esophagus connected the with pharyngeal plexus nerve branches. The intramural nerves branches connected with each other, forming an anastomosis network. The distribution of the arteries in the human esophageal wall did not have clear accompany relationship with the nerves in the wall.
Conclusion Both of arteries and nerves in human esophagus wall form anastomosis networks, but without clear accompany relationship.
