目的探讨婴儿肺不张的镜下表现和病因。方法收集我院2005年3月-2008年10月32例婴儿肺不张X线检查,纤维支气管镜检查等临床资料,分析婴儿肺不张纤维支气管镜下表现及病因。结果镜下表现:右上叶异常25例,占78.1%,右中叶异常2例,占6.25%,右下叶异常4例,占12.5%,左主支气管异常1例,占3.12%。病因分析:普通炎症20例,占62.5%,先天性支气管发育异常8例,占25%,结核1例,占3.12%,异物1例,占3.12%,纤维素性支气管炎1例,占3.12%。结论婴儿肺不张以右上叶多见,其次是右中下叶及左侧。婴儿肺不张的病因以炎症为多见,其次为先天性支气管发育异常。
Objective To investigate the microscopic appearance and etiology of infants with atelectasis. Methods The clinical data of 32 cases of atelectasis, bronchoscopy and other clinical data of infants from March 2005 to October 2008 in our hospital were collected to analyze the manifestations and etiology of infants with atelectasis fiber bronchoscopy. Results The microscopic findings showed that there were 25 cases (78.1%) of the right upper lobe abnormalities, 2 cases of right middle lobe abnormalities (6.25%), 4 cases of right lower lobe abnormalities (12.5%) and 1 left main bronchus abnormality (3.12%). Etiological analysis: 20 cases of common inflammation, accounting for 62.5%, 8 cases of congenital bronchial dysplasia, accounting for 25%, tuberculosis in 1 case, accounting for 3.12%, foreign body in 1 case, accounting for 3.12%, cellulose bronchitis in 1 case, accounting for 3.12% . Conclusion Infant atelectasis is more common in the right upper lobe, followed by the right lower lobe and the left. Infant atelectasis due to inflammation is more common, followed by congenital bronchial dysplasia.
