Extrauterine pregnancy: symptoms, signs and treatments

Extrauterine pregnancy is a complication that occurs infrequently during pregnancy. It is characterised by the growth of the foetus outside the uterine cavity. It usually never goes unnoticed. Its signs and symptoms can be noticed by the pregnant woman. The diagnosis is then confirmed by an interrogation, a clinical examination and additional tests (ultrasound or laparoscopy). The treatment to be put in place is urgent.

Ectopic pregnancy

What is an extra-uterine pregnancy?

Extrauterine pregnancy (EGU) is also called ectopic pregnancy. It is a problematic pregnancy in relation to the place where the embryo develops. The embryo develops during a normal pregnancy in the mother's uterus.

However, there are times when the egg fertilized by the sperm does not implant in the uterus at the very beginning of the pregnancy. It then develops in the fallopian tubes or even in the ovaries, in the abdomen or cervix.

It is called an extrauterine pregnancy when the embryo implants and develops in these locations, outside the uterus.

The ultrasound is usually performed using a probe positioned in the vagina. This allows a better view of the uterus than with a probe simply placed on the belly.

A laparoscopy is often necessary. A laparoscopy allows the diagnosis of an extrauterine pregnancy to be confirmed with certainty and to say where the foetus has implanted itself.

In very rare cases, the removal of both fallopian tubes has had to be carried out in the case of several advanced extra-uterine pregnancies. In this case, the couple must resort to IVF to give birth to a child.
