【摘要】：目的观察支气管肺发育不良患儿胸部CT表现。方法收集经临床确诊的支气管肺发育不良患儿42例,根据胎龄和吸入氧浓度分为轻、中、重度,均接受64层螺旋CT扫描及薄层重建,回顾性分析所有患儿的胸部CT表现。结果胸部CT多表现为囊泡影(27/42,64.29%),双肺透光度减低、呈广泛或局部磨玻璃样改变(26/42,61.90%),条片状致密影(23/42,54.76%)及条索状、网格状、蜂窝状(16/42,38.10%);胸膜增厚4例,胸腔积液2例。囊泡影发生于双肺上下叶者15例(15/27,55.56%),其中10例发生于右肺中叶;仅发生于肺下叶者8例;仅发生于肺上叶者3例(3/27,11.11%);发生于双肺下叶及右肺中叶者1例。轻、中、重度支气管肺发育不良患儿中,囊泡影检出率分别为53.33%(8/15)、57.14%(8/14)、84.62%(11/13),差异无统计学意义(P=0.094);累及肺叶数(中位数)分别为1.0、1.5、4.0,差异有统计学意义(P0.05)。结论支气管肺发育不良常见的CT征象为囊泡影、局部或广泛磨玻璃影、致密影、条索状、网格状、蜂窝状影。囊泡影可发生于双肺,以肺下叶居多,胸膜下多见;囊泡影累及肺叶数越多,提示患儿临床表现越严重。
[Abstract]:Objective to observe the chest CT findings of children with bronchopulmonary dysplasia. Methods 42 cases of bronchopulmonary dysplasia were collected. According to gestational age and inhaled oxygen concentration, 42 cases were divided into mild, moderate and severe groups. All of them underwent 64-slice spiral CT scan and thin slice reconstruction. The chest CT findings of all the children were analyzed retrospectively. Results most of the chest CT findings were as follows: 27 / 42 / 64.29% vesicle, decreased double lung transmittance, wide or local glass-like changes, 26 / 42 / 61.90 and 23 / 42 / 54.76 as well as stripe, mesh, honeycomb 16 / 422 / 38.10, pleural thickening in 4 cases and pleural effusion in 2 cases, and pleural thickening in 4 cases and pleural effusion in 2 cases. The vesicles occurred in 15 cases with 15 / 2755.56 lesions in the upper and lower lobes of the lungs, including 10 cases in the middle lobe of the right lung, 8 cases in the lower lobe of the lung, 3 cases in the upper lobe of the lung, 1 case in the lower lobe of both lungs and 1 case in the middle lobe of the right lung. In the children with mild, moderate and severe bronchopulmonary dysplasia, the positive rate of vesicles was 53.33%, 57.14%, 84.62%, the difference was not statistically significant (P < 0.094), the number of pulmonary lobes involved (median) was 1.01.54.0, the difference was statistically significant (P 0.05). Conclusion the common CT signs of bronchopulmonary dysplasia are vesicle, local or extensive ground glass shadow, dense shadow, stripe, mesh and honeycomb. Vesicles may occur in both lungs, mainly in the lower lobe of the lung, and most in the subpleural area, and the more the number of lobes involved in the vesicle is, the more serious the clinical manifestation is.
