Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
A woman may shed the lining in the form of a decidual cast, which may be mistaken as a miscarriage, when, in fact, the ectopic pregnancy still persists. A decidual reaction can be observed in tissue of the peritoneum and ovary during a pregnancy, and represents a response of stromal tissue to progesterone.
Bleeding in excess of this norm in a nonpregnant woman constitutes gynecologic hemorrhage. In addition, early pregnancy bleeding has sometimes been included as gynecologic hemorrhage, namely bleeding from a miscarriage or an ectopic pregnancy, while it actually represents obstetrical bleeding. However, from a practical view, early pregnancy ...
“Passing the decidual cast is not necessarily a sign of a serious health condition. The only exception is if it is associated with an ectopic pregnancy, or no pregnancy inside the uterus, that ...
Symptoms include vaginal bleeding, abdominal pain, premature labor and threatened miscarriage. [6] Ultrasonography is the preferred method of diagnosis. [7] A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. The hematoma is considered small if it is under 20% of the size of the sac and large if ...
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications. [1]
It takes place in normal pregnancies as well as when there are obstetric or trauma related complications to pregnancy. Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange taking place across a membrane in the placenta made of two layers, the syncytiotrophoblast ...
Ectopic decidua are decidual cells found outside inner lining of the uterus. This condition was first described in 1971 by Walker [1] and the name 'ectopic decidua' was coined by Tausig. [2] While ectopic decidua is most commonly seen during pregnancy, it rarely occurs in non-pregnant people, accompanied by bleeding and pain. [citation needed]
