摘　　要：目的探讨食管颈段供血动脉的来源及分布情况,为临床应用补充解剖学资料。方法利用成、幼年尸体25具,红色乳胶灌注后剥离,进行解剖学观察与测量。结果得出该部供血动脉主要来源于甲状腺下动脉的分支,占该段食管供血动脉总支数的71.43%;供血动脉可游离长度平均为(16.01±9.15)cm,起点外径平均为(0.94±0.26)cm。结论其血供评价单纯从器官外角度是丰富的,但应综合考虑器官内外的血管构筑。Objective To evaluate the origin and distribution of the extraorgan supply arteries for cervical esophagus, and offer anatomical data for clinical application. Methods Total 25 corpses from adults and infants were performed in this study. Red lactopren was used to perfuse to show extraorgan supply arteries of cervical esophagus. Then, we dissected and measured extraorgan supply arteryies of cervical esophagus. Results The supply arteries of cervical esophagus mainly come from the branches of inferior thyroid arteries were found, which accounts for 71.43% of the total supply arteries of cervical esophagus. The average length of the supply arteries was about 16.01±9.15 cm, and the average outside diameter was nearly 0.94±0.26cm. Conclusion The supply arteries are abundant outside the esophagus, but angioarchitecture should be generally considered outside and inside the esophagus.
