The following will provide a simple understanding and introduction to this issue, hoping it will be helpful to everyone!

The blood sinus of the embryo does not affect the normal birth of the fetus, is not easy to cause internal bleeding. If the sinus does not expand, it will not affect the development of the baby. Sometimes, the sinus may shrink or regress with the increase of pregnancy weeks.

Can placental sinus be examined by amniocentesis?

The solution of placental sinus actually depends on the size and location of the sinus. There is a possibility that the placental sinus will not shrink properly after the baby is born, leading to internal bleeding, which is the most critical; it is also possible to appear incomplete placental detachment due to placental implantation in the uterine muscle layer, leading to incomplete placental detachment and internal bleeding; also, the marginal placental detachment surface is close to the uterine orifice, which is very easy to cause bacterial invasion of the placental detachment surface and produce infection; marginal fetal bleeding in the later stage of pregnancy can lead to premature delivery of pregnant women, causing fetal intrauterine hypoxia and even death, and it is recommended to perform cesarean section for delivery.

Placental sinus refers to the localized expansion of blood vessels within the embryo. Generally, it is difficult to regress spontaneously. For those with placental sinus, it is best to avoid stimulating the uterus, so the risk of amniocentesis is very high, and it is not recommended to perform amniocentesis for examination.
