The authors present the case of a 28-year-old nulliparous woman, who successfully carried a term pregnancy in a unicornuate uterus with a solid non-communicating rudimentary horn, and a history of myomectomy, without cerclage placement or tocolytic therapy. The patient was admitted to the present clinic for uterine fibroids and menorrhagia. The patient underwent laparotomy, during which a myomectomy was performed. Twelve months after the surgery, the patient conceived spontaneously. Routine obstetric ultrasounds revealed normal intrauterine fetal development. Cerclage and tocolytic therapy were not indicated at any stage of the pregnancy. A live female neonate was delivered via cesarean section at 39 weeks' gestation.
