Massive obstetric hemorrhage during cesarean section in a patient after conception by frozen-thawed embryo transfer: a case report

Abstract

Abstract Background Placenta accreta is a major cause of massive obstetric hemorrhage during cesarean section. In recent years, pregnancy by in vitro fertilization-embryo transfer has been reported as a risk factor for placenta accreta. Case presentation A 36-year-old G1P0 woman with systemic lupus erythematosus became pregnant by frozen-thawed embryo transfer. Emergency cesarean section was performed under general anesthesia due to the diagnosis of non-reassuring fetal status. The placenta invaded the myometrium and completely covered the entire anterior uterine wall. Following birth, 3000 mL of blood loss required rapid fluid infusion and blood transfusion. Total hysterectomy was performed because the placenta could not be separated from the uterine wall. Histological examination revealed placenta accreta/increta. Conclusions When performing cesarean section on patients who have undergone frozen-thawed embryo transfer, preoperative examinations to assess for placenta accreta should be performed, and the anesthetic management should include sufficient planning for massive obstetric hemorrhage.
