Role of three vessels and trachea view in ultrasonic diagnosis of fetal heart disease and great artery abnormality / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the role of three vessels and trachea view (3VT) in diagnosis of fetal heart disease and great artery abnormality.Methods 39 pregnant women undergoing fetal ultrasound scan and diagnosed with great artery abnormality were enrolled in this study.Then the image characteristics and significance of 3VT in these 39 cases were analyzed and evaluated.Results In these 39 cases proved by autopsy,persistent truncus arteriosus(7 cases),transposition of the great arteries(7 cases),coarctation of the aorta(5 cases),tetralogy of Fallot (4 cases),pulmonary stenosis (3 cases),hypoplastic left ventricle syndrome(2 cases),persistent left superior vena cava (2 cases),pulmonary valve stenosis with single ventricle(2 cases),Ebstein anomaly with pulmonary stenosis (1 case),interruption of the aortic arch( 1 case),hypoplastic right ventricle(1 case),dextroaortic arch (1 case),and ductus arteriosus stenosis( 1 case) were detected.All of them had anomalies performance on 3VT.While in the 2 cases of double outlet right ventricle,only one eoncurrenting with pulmonary artery stenosis showed reduced inner diameter of pulmonary artery on 3VT.According to the performance of 3VT in great artery abnormality,it could be divided into 4 categoriesabnormal location,abnormal ratio,abnormal amount and abnormal blood direction of great artery.Conclusions 3VT is a useful supplement to the 4-chamber view,and has significant value in diagnosis of fetal heart and great arteries abnormities.
