During pregnancy, women need to undergo multiple prenatal check ups, and some reports may include specialized terms such as the double ring sign. This type of term can make pregnant women unaware of its meaning and worry greatly about it. So, what does the double ring sign of pregnancy mean?
Double ring sign refers to a professional term that describes certain characteristics that occur during pregnancy after undergoing ultrasound examination. Usually, at 5-8 weeks of pregnancy, a semi-circular and narrow dark area can be seen between the decidua and decidua. At this time, the gestational sac has not yet filled the entire female uterine cavity, resulting in the appearance of such a dark area, which is called the double ring sign.
If pregnant women still cannot understand this well, then in layman's terms, the double ring sign refers to the appearance of two circular sacs in the female uterus, one of which is commonly known as the gestational sac. Through the gestational sac, another small sac, the yolk sac, can also be seen. When these two sacs are examined by ultrasound, they will look like two rings, which is called the double ring sign.
The appearance of the double ring sign is also an early stage after pregnancy, and it is necessary to undergo another B-ultrasound examination around 10 days after this stage to determine whether there is normal embryonic heart development. If both show normal development, it indicates that the pregnancy is progressing healthily.
