【摘要】：目的探讨先天性支气管闭锁的多层螺旋CT表现。方法回顾性分析我院收治的15例先天性支气管闭锁的病例,男7例,女8例,年龄6~44岁,分析多层螺旋CT上病变的位置、边界,病灶内支气管及肺血管情况,占位效应等特征。结果先天性支气管闭锁发生于上肺病灶11例,下肺病灶6例。单个肺段发生11例,多个肺段发生4例,上、下肺同时发生2例,上、中肺1例,两上肺1例。所有病例病灶表现为局限性透亮度增高区,与正常肺组织分界欠清,其内肺血管细小,可见正常肺组织呈尖角状突入病灶内。所有病变内均见支气管扩张,合并支气管黏液栓11例,"指套征"8例。病灶具占位效应11例。合并感染3例,先天性肺气道畸形2例。结论支气管闭锁为支气管树的先天性发育畸形,可持续至成人期。当肺野内局限性肺过度充气特别是合并管状、指套状密影,以及肺血管细小时需考虑到支气管闭锁。
[Abstract]:Objective to investigate the multi-slice spiral CT findings of congenital bronchial atresia. Methods Fifteen cases of congenital bronchial atresia in our hospital were retrospectively analyzed, including 7 males and 8 females, aged 644 years. The location, boundary, bronchus and pulmonary vessels of the lesions and the space occupying effect were analyzed on multislice spiral CT. Results congenital bronchial atresia occurred in 11 cases of upper lung lesions and 6 cases of lower lung lesions. There were 11 cases of single lung segment, 4 cases of multiple lung segments, 2 cases of upper and lower lung simultaneously, 1 case of upper, 1 case of middle lung and 1 case of two upper lung. In all cases, the lesion presented as the local hyperluminance area, which was not well separated from the normal lung tissue, and the pulmonary vessels were small, and the normal lung tissue showed a sharp angle into the lesion. Bronchiectasis was found in all lesions, with bronchial mucus embolus in 11 cases and finger cuff sign in 8 cases. There were 11 cases of site occupying effect of diseased cooker. There were 3 cases of complicated infection and 2 cases of congenital pulmonary tract malformation. Conclusion bronchial atresia is a congenital deformity of bronchial tree, which can continue to adult stage. Bronchial atresia should be taken into account when localized lung hyperinflation in the field, especially with tubular, phalanx, and small pulmonary vessels.
