Abstract:
Objective To evaluate prenatal diagnosis value of echocardiography in pathological types,differential diagnosis and accompanied malformations of fetal persistent truncus arteriosus(PTA).MethodsTwenty-four cases of PTA selected from 1 392 cases were analysed,who were definitely diagnosed to be suffered from cardiovascular malformation by fetal echocardiography.The ultrasound findings,pathological results and followed up were analysed.According to Van Praagh classification,the type IV PTA was excluded in this study which was classified into pulmonary artery atresia.Results The total PTA were 24 cases,in which 10 cases of A1 type,3 cases of A2 type,9 cases of A3 type,and 2 cases of A4 type.Nine cases of PTA accompanied other cardiac anomalies,and 1 case of PTA accompanied both cardiac anomalies and extracardial malformations.Two PTA cases were born,one was A1 type underwent surgical intervention,and the other was died due to multiple organ-failure.Fourteen PTA cases were termination and 7 cases were confirmed by pathology.Seven women pregnant again,of which 5 cases were born while only one was diagnosed atrial septal defect after birth,2 pregnant women were still during follow-up.Eight PTA cases follow-up were lost.Conclusions A1 type and A3 type of PTA have high incidence in fetus.Accompanied cardiac anomalies is certainly related to different types.Combination of multiple ultrosund techniques can diagnose PTA prenatally,make accurate classification and detect accompanying malformations,which is of great significance to offer proper pregnancy counselling and postpartum treatment.
