Perioperative Considerations for Hysterectomy in Second-Trimester Molar Pregnancy.

BACKGROUND

Second-trimester complete molar pregnancies are rare. Due to a later presentation, means to reduce surgical and long-term morbidity from hemorrhage, hyperthyroidism, and gestational trophoblastic neoplasia risk should be considered.

CASE: A 48-year-old woman presented at 17 6/7 weeks of gestation with vaginal bleeding, with a human chorionic gonadotropin (hCG) level of 483,906 milli-international units/mL, biochemical hyperthyroidism, and ultrasonographic suspicion for complete molar pregnancy. The patient received preoperative uterine artery embolization and antithyroid medication before undergoing total abdominal hysterectomy. Her thyroid function and hCG level normalized by 1 week and 69 days postoperatively, respectively.

CONCLUSION

Uterine artery embolization and hysterectomy may reduce surgical blood loss and lower the risk of malignancy for patients at high risk for gestational trophoblastic neoplasia. Preoperative treatment of hyperthyroidism with gestational trophoblastic disease can reduce morbidity from thyrotoxicosis.
