目的：旨在为气管前间隙内病变的临床影像学诊断提供解剖学基础。方法：在２０具成人胸部连续横断面标本上，观测了气管前间隙及其内的淋巴结。结果：①气管前间隙位于大血管与气管之间，前后径为６．３８～１２．１４ｍｍ，横径为１２．９３～２１．４０ｍｍ；②其中，该间隙下份，位于主动脉弓右侧、气管前方、上腔静脉后方的区域，略呈三角形，称此为气管前腔静脉后间隙，其内恒定地出现奇静脉淋巴结，测得长径为７．４０±１．７０ｍｍ。结论：在断面标本上可清晰显示气管前间隙，从而有助于气管前间隙内病变的影像学诊断
Objective: To provide an anatomical basis for the clinical imaging diagnosis of lesions in the anterior tracheal space. Methods: In 20 adult chest continuous cross-sectional specimens, the anterior tracheal space and its lymph nodes were observed. Results: ① The anterior tracheal space was located between the large vessels and the trachea, with anteroposterior diameter of 6.38 ~ 12.14mm and transverse diameter of 12.93 ~ 21.40mm; ② Among them, the gap under the gap was located on the right side of the aortic arch, In front of the superior vena cava, the area behind the superior vena cava is slightly triangular, which is referred to as the posterior vena cava posterior gap, in which azygous lymph nodes persist, with a long axis of 7.40 ± 1.70 mm. CONCLUSIONS: Anterior tracheal space can be clearly visualized on the cross-sectional specimen to aid in the imaging diagnosis of lesions in the anterior tracheal space
