Cervical varices: an unusual etiology for third-trimester bleeding.

We report an unusual etiology for third-trimester bleeding. A pregnant patient underwent sonographic evaluation after presenting in the third trimester with uterine contractions and bleeding per the vagina. Massive cervical varices were identified on prenatal sonography as the cause of the bleeding and resulted in cesarean delivery and gravid hysterectomy. Cervical varices may result in significant maternal morbidity despite prenatal diagnosis.
