What a uterine septum is
A uterine septum is a congenital abnormality in which a wall of tissue divides the cavity of the uterus in two, completely or partly. It is the commonest congenital abnormality of the uterus. The tissue of the septum has a poor blood supply, which makes it difficult for an embryo to implant and grow there.
Why it matters
- Recurrent miscarriage, particularly in the first trimester.
- Infertility or implantation failure in IVF cycles.
- Preterm birth.
- Abnormal fetal presentation towards the end of pregnancy.
Many women with a septum never have any problem, and the abnormality is found by chance. The diagnosis is made with a three-dimensional ultrasound scan, sonohysterography or hysteroscopy.
The operation
The correction is done hysteroscopically — that is, through the cervix, with no incision in the abdomen. Using a fine endoscope the surgeon sees inside the uterus and divides the septum, so that the two halves become one smooth cavity. The operation usually takes less than an hour and is performed as a day case.
After the operation
Return to everyday activities is quick, within a few days. A follow-up check of the cavity is usually arranged before trying to conceive again. Your doctor will tell you how long to wait and what results to expect in your own case.
