Abstract:

Objective

To analyze the two-dimensional gray scale and color Doppler echocardiography characteristics of fetal isolated complete pulmonary venous drainage (TAPVC) , and to explore the application of four-dimensional time-space correlation imaging (STIC) and high definition flow imaging (HD-flow) in the prenatal diagnosis of isolated TAPVC.

Methods

A retrospective analysis was performed on 16 cases of fetal isolated TAPVC at Guangxi in Maternity & Child Healthcare Hospital. Nine cases were diagnosed by two-dimensional gray scale and color Doppler echocardiography from January 2016 to January 2018, and seven cases were diagnosed based on two-dimensional echocardiography and four-dimensional STIC and HD-flow from February 2018 to March 2021. All of the above cases were both diagnosed by direct and indirect ultrasonography signs, and all cases were followed up.

Results

The study included supracardiac type TAPVC in 12 (12/16) cases, cardiac type in 2 (2/16), and infracardiac type in 2 (2/16). Eight cases were found with direct ultrasound signs. Eight cases were found with indirect signs, including coronary sinus dilation in 2 cases, vertical vein or superior vena cava widening in 5, and abnormal blood vessels in the hilar area of the liver in 1.The four-dimensional STIC/HD-flow reconstruction images of 7 cases all showed that the 4 pulmonary veins were connected to the common pulmonary vein and joined into the systemic vein through vertical veins or the coronary sinus (right atrium).

Conclusions

The combination of direct and indirect signs of prenatal two-dimensional gray scale and color Doppler echocardiography is more helpful for the diagnosis of isolated fetal TAPVC, and four-dimensional STIC/HD-flow can provide more valuable information.
