Abstract:
Objective To observe the features of fetus unilateral pulmonary agenesis in antenatal ultrasonography and analyse the causes of misdiagnosed,so that fetus unilateral pulmonary agenesis can be known more deeply.Methods From January 2012 to October 2017,8 fetuses underwent prenatal ultrasound examination of fetal system in Guangdong Maternal and Child Health Hospital.The prenatal ultrasound data and postnatal clinical data were retrospectively analyzed.Results Among 8 cases of unilateral pulmonary agenesis,there were 4 males and 4 females,5 cases involving right lung,3 cases involving left lung,3 cases of single lung absence,and 5 cases combined with other deformities.There were 4 cases of induced labor,and 4 cases of surviving children were confirmed unilateral pulmonary agenesis by chest computed tomography (CT) examination.2 cases of missed prenatal diagnosis were left pulmonary agenesis,including 1 case only found left pulmonary artery absence and 1 case only found left axis deviation and cardiac enlargement before delivery.Conclusions Cardiac displacement and absence of left or right pulmonary artery are important clues for prenatal ultrasound diagnosis of fetal unilateral pulmonary absence.Prenatal ultrasound is the preferred method to detect and diagnose fetal unilateral pulmonary absence.
