Uterine Anatomic Abnormalities & Miscarriage

Uterine anatomic abnormalities, also known as uterine malformations, can interfere with the ability to carry a pregnancy to term and lead to recurrent miscarriage.


Uterine anatomical abnormalities & repeated miscarriage

More than 12 percent of recurrent miscarriages are linked to uterine abnormalities that are congenital (present at birth). The uterus forms between 8 and 16 weeks of fetal development. If there are problems during any of the three stages of uterine development, the uterus can fail to form properly.

Women with uterine abnormalities may experience higher preterm delivery and first trimester miscarriage than those with normal uterine anatomy.


Types of uterine abnormalities

Some examples of congenital uterine anomalies include the following:



Diagnosis of uterine anatomic abnormalities

Uterine anatomic abnormalities are usually diagnosed through the following:



Symptoms of uterine anatomic abnormalities

Often there are no symptoms of uterine abnormalities and the conditions may not be discovered without pelvic examination or imaging studies. When symptoms are present, they include:



Treatment & management of uterine anatomic abnormalities

Uterine anatomic abnormalities that impact pregnancy retention may require surgical treatment. Septate uterus may require removal of the band dividing the uterus. Rarely, bicornuate uterus is treated surgically, although treatment is not necessary in most cases.

Surgery is not typically attempted in the case of didelphic uterus, unless the wall separating the cavities is very thin and the health of the fetus is threatened.

In some cases of unicornuate uterus, there is a rudimentary horn and tube that occur when one Mullerian duct fails to develop properly. Studies have shown removal of the rudimentary horn is beneficial to reproductive outcome.

Arcuate uterus requires no treatment.

Cervical cerclage may be indicated, if there is an incompetent cervix associated with a uterine anatomic abnormality.
