What is good Decidual reaction in pregnancy?
A decidual reaction is a feature seen in very early pregnancy where there is thickening of the endometrium around the gestational sac. A thin decidual reaction of less than 2 mm is considered one of the features suggestive of an anembryonic pregnancy 2.
When does the decidual reaction occur?
In humans, decidualization occurs after ovulation during the menstrual cycle. After implantation of the embryo, the decidua further develops to mediate the process of placentation.
What is Choriodecidual reaction?
The sac is surrounded by a white echogenic rim (choriodecidual reaction) The sac is located in the uterine fundus. The sac is not implanted on the midline, but eccentrically (to one side of the uterine cavity line).
What is implantation or Decidualization?
Once implantation occurs and the embryo breaches the luminal epithelium, the stromal cells surrounding the implanting embryo transform into a decidua by a process called decidualization [9,95].
Is Decidual reaction is normal in pregnancy?
The decidual reaction is most prominent between 18 and 32 weeks with a decline near term. There is also a wide variation in the extent of decidual reaction during normal pregnancy preventing its use as a sensitive indicator of normal versus abnormal pregnancy.
What is Decidualization of the endometrium?
Decidualization refers to the functional and morphological changes that occur within the endometrium to form the decidual lining into which the blastocyst implants. These changes include the recruitment of leukocytes and, importantly, the differentiation of endometrial stromal fibroblast cells (ESCs) into DSCs.
Does gestational sac confirm pregnancy?
The gestational sac is usually the first sign of pregnancy on ultrasound. When correlated with HCG levels, the presence of a gestational sac can be very helpful in detecting ectopic or heterotopic pregnancy. It can also be used to determine if you have experienced a very early miscarriage.
What is Choriodecidual?

What is endometrial Decidualization?
What is the decidua Capsularis?
[ kăp′sə-lâr′ĭs ] n. The layer of endometrium overlying the implanted chorionic vesicle that progressively diminishes as the chorionic vesicle enlarges.
What is Intradecidual sac?
Intradecidual sac sign (IDSS) is a useful feature in identifying an early intrauterine pregnancy (IUP) as early as 25 days of gestation1. The threshold level (earliest one can see the sign) is 24 days of gestation and the discriminatory level (one should always see the sac) is 47 days.
