【摘要】：目的:探讨MSCT对儿童气管支气管发育异常的诊断价值。方法:搜集经我院诊断、资料完整的先天性气管支气管发育异常患儿29例,所有病例均行胸部MSCT扫描,利用三维重组技术显示气管支气管树,重组技术包括多平面重组(MPR)、容积再现(VR),仿真内镜(VE)等。结果:气管性支气管10例(移位型9例,额外型1例)均为上叶支气管直接从气管发出。先天性气管支气管壁发育异常12例,其中气管膈膜1例,气管憩室1例,气管支气管狭窄10例(血管畸形压迫7例,血管瘤压迫3例)。先天性气管食管瘘1例,支气管桥1例,支气管不发育或发育不良5例,其中2例伴肺动脉缺如,1例伴肺动脉发育不良。结论:MSCT作为儿童气管支气管发育异常的首选检查方法,可明显提高诊断符合率,可作为诊断本病的另一个"金标准"。
[Abstract]:Objective: to investigate the value of MSCT in the diagnosis of tracheobronchial dysplasia in children. Methods: 29 cases of congenital tracheobronchial dysplasia diagnosed in our hospital were collected. All the patients underwent chest MSCT scan. The tracheobronchial tree was displayed by three-dimensional recombination technique. The reconstruction techniques included multiplanar reconstruction and volume reconstruction. Results: 10 cases of tracheobronchial bronchus (9 cases of transposition type and 1 case of extra type) were directly from the trachea and 12 cases of congenital tracheobronchial wall were abnormal. There were 1 case of trachea diaphragm, 1 case of tracheal diverticulum, 10 cases of tracheobronchial stenosis (7 cases of vascular malformation, 3 cases of hemangioma compression), 1 case of congenital tracheoesophageal fistula and 1 case of bronchial bridge. There were 5 cases of bronchial dysplasia or dysplasia of bronchus, of which 2 cases were accompanied with pulmonary artery deficiency and 1 case with pulmonary artery dysplasia. Conclusion: MSCT is the first choice for detecting tracheobronchial dysplasia in children. It can obviously improve the diagnostic coincidence rate and can be used as another "gold standard" for the diagnosis of this disease.
