Polyhydramnios, thickening of the soft tissue in the neck, and a suspected interventricular septal membrane defect.

Patient's question:

Amniotic fluid depth: 68mm
Index: 243mm
Cervical thickness: 9.9mm
Visible: 36mm, 37mm small anechoic foci
Interventricular septal membrane appears to have interventricular flow, width about 2.2mm

Doctor's answer:

The measured values of the sound are quite close to your actual month, and they are within the normal range. At the same time, the length of the femur is also within the normal range, and the amniotic fluid is just slightly above normal, not excessively so. Therefore, from the ultrasound perspective, there are no significant abnormalities in your fetus, so it is generally not necessary to perform cordocentesis. As long as the amniotic fluid is only slightly above normal, there will be no adverse effects.
