What is the difference between a gestational sac with or without an echo area?

In the early stages of pregnancy, women need to go to the hospital for detailed examinations, including a gestational sac echo test. Through this examination, it can be seen that the uterus of pregnant women will enlarge and there will be a circular halo at the bottom of the uterus. This is called the gestational sac echo. It is also possible that the result of the examination will be that the gestational sac has no echo. So what is the difference between having an echo or not?

First, what does it mean that the gestational sac has an echo?

The echo of the gestational sac means that the fetus is developing well, and the echo of the gestational sac is also one of the signs to confirm pregnancy. Generally speaking, women take an early pregnancy test about 35 days after their menstruation, and the echo of the gestational sac can be seen under ultrasound 45 days after their menstruation. The sonogram shows an enlarged uterus, with a circular halo near the bottom of the uterus, which is the echo of the gestational sac. The sac wall is intact, with uniform thickness and consistent echo intensity, and there is a liquid-free echo area inside the sac.

Second, what does it mean that the gestational sac has no echo?

The absence of echo in the gestational sac means that the fetus may have stopped developing, and reasons such as threatened abortion should be considered. In this case, you should pay attention to rest in time and actively carry out fetal preservation treatment. You can consider using some progesterone, dydrogesterone tablets and other drugs for treatment, and conduct regular check-ups. Eat a balanced diet and improve nutrition. Avoid strenuous exercise and heavy physical labor.

If no echo is heard for a long time, it is best for the pregnant mother to go to the hospital for an abdominal ultrasound examination. At the same time, it is best to combine the measurement of chorionic gonadotropin levels to see whether the gestational age is met. If the embryo is confirmed to have stopped developing, uterine cleaning is required in time.

Third, what is the concept of gestational sac

The gestational sac is the initial form of pregnancy. It is the primitive placental tissue and a small embryo wrapped by the amniotic membrane and vascular network.

Size: It changes with the gestational age. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy.

Position: 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.

Shape: It is normal for the gestational sac to be round, oval, and clear. If the gestational sac is irregular, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

Fourth, what is the concept of echo

Echo is an ultrasound term. Since B-ultrasound is an imaging examination, the different densities of different tissues lead to different degrees of sound wave attenuation, thus reflecting normal or abnormal tissues. The most common ones are high echo, low echo, and no echo. The higher the echo, the greater the tissue density. High-echo areas are mostly malignant tumors, calcifications, bones, metal rings, etc.; low-echo areas are mostly uterine fibroids (mostly with capsules), adenomyomas, or semi-solid and semi-cystic ovarian masses; anechoic areas are mostly seen in benign ovarian masses, which are mostly filled with fluid.
