Abstract:
Objective:To summarize the prenatal diagnosis features, classification and pregnancy outcome of anomalous origin of one pulmonary artery branch from the aorta (AOPA).Methods:This study involved 14 cases who were prenatally diagnosed with AOPA in Guangzhou Women and Children's Medical Center between June 2016 and August 2022. Prenatal and postnatal echocardiographic features, postpartum diagnosis, surgical treatment and pregnancy outcome in these cases were summarized and analyzed by descriptive analysis.Results:Out of the 14 fetuses, there were seven fetuses with proximal-type AOPA (including three isolated AOPA, three Berry syndrome and one with interruption of the aortic arch, aorticopulmonary septal defect and ventricular septal defect) and another seven with isolated distal-type of AOPA. Among the seven cases of proximal-type AOPA, two were terminated and five were born alive. The postpartum diagnosis was consistent with the prenatal diagnosis in the five babies who later underwent surgical treatment with good outcomes. Among the seven cases of distal-type AOPA, one was terminated; two were initially diagnosed as AOPA in the neonatal period but then as unilateral absence of pulmonary artery (UAPA) due to tapering or closure of the ductus arteriosus during follow-up; the other four were confirmed with UAPA after delivery. All of the six neonates underwent surgical treatment with good outcomes.Conclusions:Prenatal diagnosis and classification of AOPA should be as accurate as possible. It is recommended that the distal-type of AOPA could be diagnosed as UAPA after delivery and treated according to UAPA. Both kinds of patients should be treated with surgery timely after delivery to ensure a good prognosis.
