To determine the location of left brachiocephalic vein (BCV) and tracheal bifurcation (TB) relative to the vertebral levels, and to ascertain the accessibility of three different corridors (C1: between the esophagus and trachea medially and the carotid sheath laterally, C2: between the right BCV and the brachiocephalic artery, and C3: between the ascending aorta and superior vena cava) for preoperative planning. From August 2008 to April 2009, normal chest CT scans of 150 subjects ranging in age from 18 to 78 years were selected. According to our definition, of the 150 studies, 132 T2 vertebral bodies (VBs) could be accessed through C1 (88.0%), 100 T3 VBs could be reached through C2 (66.7%), and 110 T4 VBs could be exposed through C3 (73.3%). The results suggest that the surgical accessibility of three different corridors is different and we conclude that T2, T3, and T4 are, respectively, readily accessible through C1, C2, and C3.
确定左头臂静脉（BCV）和气管隆突（TB）相对于椎体水平的位置，并确定三条不同通道（C1：内侧为食管与气管之间，外侧为颈动脉鞘；C2：右侧头臂静脉与头臂动脉之间；C3：升主动脉与上腔静脉之间）在术前规划中的可及性。选取2008年8月至2009年4月间年龄在18至78岁的150名受试者的正常胸部CT扫描图像。根据我们的定义，在这150份研究中，132个T2椎体可通过C1通道到达（88.0%），100个T3椎体可通过C2通道到达（66.7%），110个T4椎体可通过C3通道暴露（73.3%）。结果表明，三条不同通道的手术可及性不同，我们得出结论，T2、T3和T4椎体分别可通过C1、C2和C3通道轻松到达。
