An abnormal uterus can sometimes be a risk factor for miscarriage and, in some cases, a cause of recurrent miscarriages. however, only some types of uterine malformations increase the risk of miscarriage and require treatment. others may not cause any problems with pregnancy at all. about 18% of women who have recurrent miscarriages have some type of uterine abnormality. Some uterine malformations are present from birth, while others develop during adulthood. most often, women with uterine abnormalities do not have any symptoms and are not aware of these malformations before they become pregnant. Diagnosis of congenital uterine malformations usually comes after a hysterosalpingogram (HSG), but this test can miss some conditions, such as uterine septum. Any abnormal HSG should be followed by a hysteroscopy. A uterine septum (septate uterus) is the most common congenital uterine anomaly, comprising roughly 55% of Mullerian duct anomalies. Congenital means that it is present at birth. A uterine septum is a band of fibrous tissue that partially or completely divides the uterus, usually without a good blood supply. If a fertilized egg implants on the septum, the placenta is unable to grow properly and miscarriage is likely, for women who have a septate uterus, the risk of miscarriage is significant. In fact, in one study nearly 67% of the women in the study with a septate uterus experienced pregnancy loss, for women who do not miscarry, a septate uterus may increase the risk of preterm birth. In fact, the same study found that the likelihood of having a full-term, normal-sized baby was only on 25%. treatment is usually minor surgery, performed during a hysteroscopy, to remove the abnormal tissue. this usually works extremely well to resolve the problem and allow women to successfully carry a full-term pregnancy
