Displaced anterior segmental bronchus and pulmonary artery is extremely rare. A keen knowledge of such variations is required in the field of pulmonary segmentectomy, for unawareness of the structural variation could lead to intra- and postoperative complications.
A 50-year-old female presented to our department with suspected lung adenocarcinoma. Preoperative 3-dimensional computed tomographic bronchography and angiography revealed anterior segmental bronchus and anterior segmental pulmonary artery variation: the anterior segmental bronchus derived from the middle lobe bronchus, accompanied by a distally distributed anterior segmental pulmonary artery branch. A right apical-posterior segmentectomy using inflation-deflation technique was performed successfully.
The keen observation and proper application of modern imaging technology and operative technique could greatly aid segmentectomy, preventing intra- and postoperative complications from happening.
前节段支气管和肺动脉移位极其罕见。在肺段切除术领域，需要对这些结构变异有深入的了解，因为对结构变异的认识不足可能导致术中及术后并发症。
一名 50 岁女性因疑似肺腺癌就诊于我科。术前三维 CT 支气管造影和血管造影显示前节段支气管和前节段肺动脉变异：前节段支气管发自中叶支气管，伴远端分布的前节段肺动脉分支。采用充气-放气技术成功实施了右肺尖后段切除术。
敏锐的观察和对现代影像学技术及手术技术的正确应用可以极大地辅助段切除术，防止术中及术后并发症的发生。
