食管下端与胃底部的静脉回流有其特殊的解剖和生理影响。其静脉回流除自食管壁内的毛细血管后小静脉集合丛形成许多血管网外,其下部的静脉和胃体腺下静脉丛相连接。胸部食管的静脉大部分引流至奇静脉分支,在食管穿经膈裂孔时即汇入膈上、膈下静脉。食管左侧静脉与右侧相似,除入奇静脉外,并引流 The esophageal bottom and venous bottom venous return has its special anatomical and physiological effects. The venous return in addition to the esophageal wall within the capillary collection of small venous plexus vascular network formed many, the lower part of the vein and the inferior vena cava connected. Most of the chest esophageal vein drainage to the azygos vein branch, in the esophagus through the diaphragm hole when the diaphragm, diaphragm infiltration. The right esophageal vein on the left and similar, except into the azygos vein, and drainage
