What is a gestational sac

The gestational sac is the primitive placental tissue, a small embryo wrapped by the amniotic membrane and vascular network. The gestational sac is the initial form of pregnancy. At that time, the fetus has not yet formed, and the fetal heartbeat is already there when the embryonic bud appears.

The gestational sac is also a product of ectopic pregnancy. The fertilized egg fails to enter the uterus at 7 days due to certain factors such as inflammation and adhesion. Ectopic pregnancy usually causes heavy bleeding, and generally the fetus cannot survive. The baby's mother herself was having an intrauterine pregnancy, but due to poor development of the uterus, the gestational sac broke through the weak top of the uterus and entered the abdominal cavity. The villi around the gestational sac sought nutrients everywhere in the abdominal cavity and then supplied them to the fetus through the placenta. Usually, such a fetus will die within two months because it has no protection from the uterine environment and lives in an extremely harsh environment with poor nutrition.

Observation of gestational sac

The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, after 35 days of amenorrhea, the gestational sac can be seen in the uterine cavity by B-ultrasound. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus; it is normal for it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.
