Bicornuate Uterus

    A bicornuate uterus is a uterus that has two horns and a heart shape. The uterus has a wall inside and a partial split outside. A bicornuate uterus is the most common congenital uterine anomaly and can impact a woman's reproductive capabilities.

    Bicornuate UterusSeveral studies show that women with a bicornuate uterus have about a 60% success rate in delivering a living child but have a higher risk of cervical incompetence. The condition is associated with an increased rate of spontaneous abortion, though the miscarriage rate is lower with a bicornuate uterus than with a septate uterus. That's probably because the blood supply to the midline indentation is better. Premature labor, a breech presentation and/or a retained or trapped placenta are also common complaints with a bicornuate uterus.

    If necessary, a bicornuate uterus can be corrected surgically. Few studies of the surgery have been published. In three studies reporting on a total of 11 women, approximately 90% successfully carried a pregnancy to term.

    Diagnostic procedures

    A bicornuate uterus can be confirmed through use of the following techniques:

    • Pelvic exam: Two horns can occasionally be palpated. 
    • Sonogram: A bicornuate uterus can sometimes be diagnosed by ultrasound
    • Laparoscopy: Provides information on the exterior shape of the uterus. 
    • Hysteroscopy: Provides information on the interior configuration of the uterus.

    Treatment

    Metroplasty surgery: To create a large uterine cavity with minimal destruction of uterine tissue is the treatment of choice.
    Cervical cerclage: Improved the fetal survival rate in selected patients. Both metroplasty and a cervical cerclage may be prescribed.
