Abstract：
BACKGROUND Pulmonary artery sling (PAS) is an anatomical vascular anomaly due to the origin of the left pulmonary artery from the right pulmonary artery, which runs posteriorly between the esophagus and trachea, resulting in compression of adjacent structures. Accurate evaluation for malformation of the pulmonary artery and severity of airway obstruction is essential to surgical strategy. This report presents the diagnosis and surgical management of pulmonary artery sling in a 12-year-old boy. CASE REPORT A 12-year-old boy had chest tightness and wheezing after exercise for 6 years. He was diagnosed with PSA based on findings from imaging tests, demonstrating the left pulmonary artery originated from the middle of the right pulmonary artery and the tracheal carina was located at the site of the T6 thoracic vertebra. The main bronchus and esophagus were compressed by the left pulmonary artery due to its ectopic origin. Then, after comprehensive preoperative assessment, the patient underwent surgical repair of PAS. CONCLUSIONS This report highlights the importance of pulmonary artery sling diagnosis, imaging, and surgical planning, and the role of a multidisciplinary team in preoperative and postoperative patient management. An individualized strategy based on the preoperative assessment, intraoperative coordination among cardiologists, surgeons, and perfusionists, and careful postoperative management are the core elements for successful PAS repair.
摘要：
背景技术肺动脉吊带（PAS）是由于左肺动脉起源于右肺动脉而引起的解剖学血管异常。它在食道和气管之间向后延伸，导致相邻结构的压缩。准确评估肺动脉畸形和气道阻塞的严重程度对于手术策略至关重要。本报告介绍了一名12岁男孩的肺动脉吊带的诊断和外科治疗。病例报告一名12岁男孩在运动6年后出现胸闷和喘息。根据影像学检查的结果，他被诊断为PSA，显示左肺动脉起源于右肺动脉的中部，气管隆突位于T6胸椎部位。由于其异位起源，主支气管和食管被左肺动脉压迫。然后，经过全面的术前评估，患者接受了PAS手术修复。结论本报告强调了肺动脉吊带诊断的重要性，成像,和手术计划，以及多学科团队在术前和术后患者管理中的作用。基于术前评估的个性化策略，心脏病学家之间的术中协调，外科医生,和灌注者，精心的术后管理是成功进行PAS修复的核心要素。
