Cervical avulsion during induced labour: diagnosis, intraoperative management and postoperative course

We report the presentation, operative management and follow-up of a 31-year-old nulliparous woman who experienced a cervical avulsion injury (CAI) during labour. The woman was induced with dinoprostone gel, followed by oxytocin infusion and had a prolonged active phase. During the second stage, fetal decelerations were noted and the consultant asked to make a plan for delivery. When assessing to perform a midpelvic instrumental delivery, a cord of tissue was felt below the fetal head. A caesarean delivery was recommended based on this finding. After delivery, injuries to the broad ligament, posterior lower uterine segment vagina and cervix were repaired. The cervix was retained with the intent that some tissue be salvaged. At 6-week follow-up, transvaginal ultrasound confirmed blood flow in the cervical tissue, though cervical insufficiency was suspected on clinical examination. Our findings reinforce the seriousness of CAI and support conservative surgical management as opposed to trachelectomy or hysterectomy.
