Multiple gestation in a unicornuate uterus - A case report

BACKGROUND: Uterine anomalies in the obstetric population have been reported to occur in 0.2-3.2% of patients, and the unicornuate uterus constitutes only 1-2% of these anomalies. CASE: A 35 year-old woman with known unicornuate uterus became pregnant with twins after controlled ovarian hyperstimulation and intrauterine insemination. The pregnancy was complicated by cervical incompetence, premature labor, dysfunctional labor, the need for cesarean delivery and postpartum uterine atony. CONCLUSION: This is the third reported successful outcome of multiple gestation following the use of assisted reproductive technologies in a patient with a unicornuate uterus. The presence of this mullerian anomaly should not be considered an absolute contraindication to the use of superovulation when treating infertility.
