A condition is said to be a congenital anomaly when it affects a person from birth. It is estimated that 6.7% of the general population suffer from such malformations of the uterus, while the incidence of congenital malformation in women suffering from infertility is 7.4%. This incidence is significantly higher in women with a history of recurrent miscarriages.
Types of congenital malformation of uterus:
Müllerian agenesis: Müllerian agenesis is a condition which occurs when the uterus, upper vagina and cervix (opening of the uterus) don’t develop correctly or at all. Women with this condition develop normal ovaries, breasts, clitoris and vulva.
The diagnoses may involve one of the following imaging techniques:
It may be possible to conceive with unicornuate uterus but it needs to managed carefully since cases of premature birth, pregnancy loss, malpresentation and fetal demise are more common in such pregnancies. A c-section may also be required instead of a normal pregnancy.
Uterus didelphys: Uterine didelphys, also known as double uterus is a rare congenital uterus anomaly. It is caused during the fetus development stage,when the small tubes which normally join to form the uterus develop into two separate structures (2 uteruses). It is possible to have one cervix (mouth of the uterus) or each structure may have its separate cervix
Women suffering from this condition usually do not feel any symptoms but some women may experience:
General & Pregnancy Complications
Diagnosis is carried out using various imaging techniques such as:
Surgery can result in better management of pregnancies, other than that it is not medically necessary to undergo treatment unless the patient is experiencing severe symptoms.
Bicornuate uterus, also known as, heart shaped uterus is a condition in which the uterus has two horns which are separated by a septum. This type of condition is one of the most common uterus anomalies along with septate uterus. It is a result of improper formation of the uterus during prenatal years. This can happen due to several reasons, one of them being exposure diethylstilbestrol (DES).
Women having a bicornuate uterus usually don’t experience any symptoms other than infertility.
In order to ascertain bicornuate uterus various imaging techniques or diagnostic laparoscopy:
Effect on pregnancy
Bicornuate uterus is known to have the following adverse effects on pregnancy:
In this condition extra tissue called the septum hangs in the uterus from the top. The septum is often shaped like a wedge and maybe small or may hang from the top to the cervix (mouth of the uterus) , thereby dividing the uterus into two cavities.
Since uterine septum is a congenital anomaly women affected by it are born with it. It is developed It happens due to the failure to absorb the dividing interior wall by the two uteri which fuse together.
Uterine septum shows no symptoms, except infertility. Most women affected by uterine septum discover they have it, when trying to understand the reason behind their infertility.
Various imaging techniques may be used in order to ascertain uterine septum:
