摘要
在７２具成人尸体上，观测了气管的结构及其与甲状腺和相邻血管的位置关系．气管颈部有６～９个气管软骨环，长度为（６．７２±０．３６）ｃｍ，左右径为（２．１２±０．２１）ｃｍ，前后径为（１．９８±０．２１）ｃｍ．甲状腺峡下缘多位于第２～４气管软骨环之间（８５％）．颈前静脉于前正中线两侧０．５～１．６ｃｍ处下行，具有前正中静脉者占１３％，有颈静脉弓者占７２％．气管与头臂干的位置关系分３种类型：不交叉型占１０％；不完全交叉型占２８％；完全交叉型占６２％，其交叉点距环状软骨下缘（６．４７±０．４１）ｃｍ．气管与左头臂静脉交叉多处于第９～１０气管软骨环之间（７５％），其交叉点距环状软骨下缘（７．３９±０．６４）ｃｍ．甲状腺最下动脉出现率为１２％．
The structure of trachea and its relation with thyroid and blood vessel was observed in 72 adult corpses.It was found that 6～9 cartilaginous rings were in the cervical part of trachea,the length,the left right and anteroposterior diameters were (6.72±0.36)cm,(2.12±0.12)cm and (1.98±0.21)cm,respectively.The inferior part of thyroid is themus(85%) was located at 2～4 cartilaginous rings.Anterior jugular vein was descending by 0.5～1.6cm sides of anterior median line.The anteromedian vein and the jugular venous arch were found in 13% and 72% corpses respectively.There were three kinds of location between trachea and trachiocephalic truncus: 10.0 % forms of non cross,27% of incomplete cross and 62% of complete cross, where the cross point was at (6.47± 0.41) cm distance of inferior part of cricoid cartilage.The cross of trachea and left brain chiocephalic vein (75%) was at 9～10 cartilaginous rings,and the cross point was at (7.39±0.64)cm distance of inferior part of cricoid cartilage.
