Abstract:

Abstract：Objective    To raise awareness of pulmonary artery sling（PAS）and to improve its early diagnosis and reduce misdiagnosis. Methods    By analyzing the information of two cases， evaluate the importance of  echocardiography，MRI and enhanced + 3D CT in early diagnosis. Results    These two patients had major clinical manifestations of recurring bucking and vomiting，and laryngeal stridor.One case was confirmed by Enhanced + 3D CT，and the another case was confirmed by echocardiography and Enhanced + 3D CT. Conclusions    The infants who had clinical manifestations such as repeatedly bucking and vomiting，laryngeal stridor，pneumonia or respiratory tract infection，and who were treated unsatisfactorily should consider PAS.Echocardiography、enhanced + 3D CT and MRI play an important role in the diagnosis of PAS.

摘要：

摘要：目的    提高对肺动脉吊带畸形（pulmonary artery sling，PAS）的认识及早期诊治水平，减少漏诊、误诊。方法     回顾分析2012年11月至2013年1月在中国医科大学附属盛京医院就诊的2例婴幼儿PAS的临床资料，并进行相关文献复习，评价增强三维CT、心脏彩超、磁共振等辅助检查在PAS诊断中的作用。结果    本文2例患儿主要临床表现为反复呛奶、喉鸣，对常规治疗效果不满意。后1例经胸部增强三维CT确诊PAS，1例经心脏增强三维CT联合心脏彩超确诊PAS。结论    对婴幼儿早期出现反复呛奶、喉鸣、肺部感染等呼吸道症状而常规治疗效果不满意者应考虑PAS存在的可能。心脏彩超、增强三维CT、磁共振等辅助检查对PAS的临床诊断具有重要价值。
