Patient's question:
The doctor performed the 4D color Doppler ultrasound. The fetus was 224. The aortic diameter of the fetus was 4.2mm, and the pulmonary artery diameter was 4.1mm. Hello, do you have any questions?Doctor's answer:
Generally, the diameter of the pulmonary artery is larger than that of the aorta. In your case, the possibility of pulmonary artery stenosis cannot be ruled out. It is recommended to undergo an echocardiogram. It is suggested to carefully examine the fetal heart through echocardiography at 24-28 weeks. Fetal heart rate should be checked; if it is below normal, it may indicate abnormal fetal heart development. The normal ratio should not exceed 1:1. It is commonly seen at a ratio of 1.2:1. If you are facing interference from a 4D ultrasound, we should actively conduct the examination and treatment, and do not hesitate to seek medical attention.
