为评价婴幼儿气管、支气管狭窄球囊扩张的疗效,作者报道经气管支气管镜检查、造影及MR证实的6例23次球囊扩张结果。年龄5周～32个月。狭窄原因:先天性2例,气管重建术后2例,血管压迫支气管2例。狭窄位于气管3例;支气管2例,气管远端和两侧支气管近端1例。6例均伴先天性心脏病,2例为左肺动脉悬吊。临床症状表现为持续或反复呼吸窘迫(5例)和肺不张(1例)。
To evaluate the efficacy of balloon dilation in bronchial and bronchial stenoses in infants and toddlers, the authors reported results of 6 cases of balloon dilation in 6 cases confirmed by tracheobronchoscopy, angiography and MR. Age 5 weeks to 32 months. Narrow reasons: congenital in 2 cases, 2 cases after tracheal reconstruction, 2 cases of vascular compression of the bronchus. 3 cases were located in the trachea narrowly, 2 cases in the bronchus, 1 case in the distal end of the trachea and the proximal bronchus on both sides. 6 cases were congenital heart disease, 2 cases of left pulmonary artery suspension. Clinical symptoms manifested as persistent or recurrent respiratory distress (5 cases) and atelectasis (1 case).
