目的：探讨儿童支气管桥畸形及其合并肺动脉吊带的临床诊治。方法回顾性分析21例确诊为支气管桥畸形或同时合并肺动脉吊带畸形患儿的临床资料和超声心动图，多层螺旋CT胸部平扫、增强及气道重组图像影像学表现。结果21例患儿中有10例为单纯的支气管桥，其中3例合并其他类型先天性心脏病；11例为支气管桥合并肺动脉吊带，其中8例合并其他类型先天性心脏病。年龄除1例外均<2岁。大多以反复呼吸道感染及阵发性呼吸困难起病。根据Wells法分为I型15例、Ⅱ型6例。其中单纯支气管桥10例均为I型，5例合并肺动脉吊带；Ⅱ型6例均合并肺动脉吊带。结论对于临床上有反复呼吸道感染的婴幼儿，应警惕支气管桥畸形可能，并注意合并肺动脉吊带。多层螺旋CT胸部平扫、增强及气道重建图像是诊断该疾病的重要方法。%Objective To explore the clinical diagnosis and treatment of pediatric bridging bronchus deformity and brid-ging bronchus with pulmonary artery sling. Methods The clinical data of the 21 cases of diagnosed bronchial bridge deformity and bronchial bridge with pulmonary artery sling, the imaging findings of all the echocardiography, MSCT chest scan, enhanced CT and reconstructive image were retrospectively analyzed. Results In 21 cases, 10 were diagnosed as bronchial bridge only, among which three cases had other types of congenital heart disease;11 cases were diagnosed of pulmonary artery sling with pulmonary artery sling, among which 8 cases had other types of congenital heart disease;their average age of the 8 cases were all younger than 2 years old, except one case;most of them had the symptoms of recurrent respiratory tract infections and parox-ysmal dyspnea. According to Wells, bronchial bridge was divided into type I and typeⅡ;15 cases were type I, 6 cases were typeⅡ, 10 patients with bronchial bridge only were all type I, 5 cases of typeⅡwere associated with pulmonary artery sling. All of the 6 cases were diagnosed as typeⅡassociated with pulmonary artery sling. Conclusions Infants and young children with clini-cal recurrent respiratory tract infections should be considered the possibility of bronchus bridge deformity, and should be paid more attention to the possibility of pulmonary artery sling. MSCT plain chest scan, enhanced CT and airway reconstructive im-age are the important ways to diagnose the disease.
