ABSTRACT
Objective To explore the clinical significance and diagnosis value of ultrasonography for fetal lung disease.Methods A total of 61 cases of fetal lung disease was diagnosed and the data were retrospectively analyzed.Results In the 61 fetus of lung disease,(1) there were 31 fetuses with congenital cystic adenomatoid adenomatoid malforamation (CCAM),the ultrasound found that there were mass in fetus lung,they were mixed echo or large cyst or more little cyst or a hyperechoic in the mass.Among them,there were 2 cases of type Ⅰ,16 cases of type Ⅱ,and 13 cases of type Ⅲ;21 cases were labored,who were CCAM-confirmed by pathology,3 fetus masses were disappeared,7 cases were CCAM-confirmed with magnetic resonance (MR) after birth.(2) There were 19 fetuses with pulmonary sequestration (PS),the sonography was slightly hyperechoic mass in the lung,including 7 cases of induced labor and confirmed by pathology as PS,and 4 cases of mass disappeared,8 cases confirmed by MR or computed tomography (CT) after birth.(3) There were 6 cases of congenital diaphragmatic hernia,the abdomnial viscera was seen in the chest,5 cases were induced labor,and 1 survived after operation.(4) There were 5 cases of pleural effusion (PE),4 cases were induced labor and 1 case of PE disappeared.Conclusions Systemic prenatal ultrasonographic examination is an reliable method which can be short-term follow-up to observe the progress and the outcome,and to provide valuable information for clinical prognosis.
