Prenatal diagnosis of primary right pulmonary agenesis: a case report / 中华围产医学杂志

ABSTRACT

We report the prenatal diagnosis and treatment of a case of primary right pulmonary deficiency. A routine ultrasound examination at 23 +6 weeks of gestation found an absent right lung, enlarged left lung, and dextroposition of the heart in a female fetus. Karyotype and chromosome microarray analysis of the amniotic fluid was normal. After multidisciplinary consultation, the pregnant woman chose to continue the pregnancy and had a normal delivery at 39 +2 gestational weeks. Apgar scores were ten at both 1 min and 5 min after birth, with no abnormal appearance of the baby, or signs of thoracic collapse other than no obvious respiratory sounds in the right lung. Both postnatal chest X-ray and CT scan indicated an undeveloped right lung. Cardiac ultrasonography revealed the absence of the right pulmonary artery and vein. The patient's breathing was stable during hospitalization and she was discharged eight days after birth. The infant was followed up at five months, and the growth and development were comparable to children of the same age.
