Pregnancy: clear egg syndrome

What does it mean if at the first ultrasound they tell us about a clear or blind egg or an anembryonic pregnancy?

Surely a new ultrasound will be needed for definitive confirmation. If the diagnosis were confirmed, it would be a non-evolutionary pregnancy.

Ultrasound remains the only way to understand if the pregnancy is proceeding normally (physiologically) or pathologically. In particular, the diagnosis of clear egg (from the English blighted ovum ) occurs when the ultrasound shows a gestational chamber without embryonic echoes and a yolk sac. It is therefore an anembryonic pregnancy .

In clear egg situations, the gestational chamber is smaller, with an irregular profile and absence of an embryonic pole at the 7th week of pregnancy.

Subsequent ultrasound checks also demonstrate a lower growth rate of the gestational chamber: 0.2 mm per day compared to 1 mm in the case of a normal pregnancy.

Obviously, some subsequent ultrasounds are needed to confirm the diagnosis of clear egg . If all subsequent ultrasounds confirm the absence of the yolk sac and the embryonic pole and there is a reduction in the growth of the chamber itself, then we speak of a clear egg.

The pale egg is responsible for nearly half of early first trimester miscarriages and is usually due to chromosomal abnormalities that prevent early embryo formation.
