Mediastinal bronchogenic cysts, regarded as congenital foregut abnormalities, are uncommon. These cysts can compress adjacent structures, causing obstructive symptoms and complications. A 57-year-old man was admitted to our hospital with complaints of tachycardia, dyspnea, and chest pain. Enhanced computed tomography revealed a 90 × 90 mm, well-defined subcarinal cystic mass causing significant compression and stenosis of the right main bronchus, right pulmonary artery, and right inferior pulmonary vein. The mass was successfully excised using one window and two-port video-assisted thoracoscopic surgery with partial resection and repair of pulmonary artery, and the postoperative course was good with no recurrence.

纵隔支气管囊肿被认为是先天性前肠异常，并不常见。这些囊肿会压迫邻近结构，导致阻塞性症状和并发症。一名 57 岁男性因心动过速、呼吸困难和胸痛入院。增强计算机断层扫描显示一个 90 × 90 mm、界限清楚的隆突下囊性肿块，导致右主支气管、右肺动脉和右下肺静脉明显受压和狭窄。采用一窗双孔电视胸腔镜手术，部分切除修复肺动脉，成功切除肿块，术后病程良好，无复发。
