RationaleUterine rupture (UR) during pregnancy is a serious obstetric complication. Here we report a case of spontaneous rupture in an unscarred uterus at 13 weeks of gestation after in vitro fertilization embryo transfer, which is not common in past references. Our focus is to understand the relationship between systemic lupus erythematosus (SLE) and UR.Patient ConcernsA 33-year-old infertile woman with a history of SLE became pregnant after in vitro fertilization embryo transfer. She presented with sudden mental fatigue and dyspnea, accompanied by sweating, dizziness and lower abdominal pain at 13 weeks of gestation.DiagnosesBlood analysis revealed anemia. Ultrasonography and plain computed tomography scan revealed intrauterine early pregnancy with effusion in pelvic and abdominal cavity. Laparotomy confirmed the diagnosis of UR.InterventionsThe patient underwent emergency laparotomy. Upon surgery, multiple myometrium was weak with only serosal layer visible, and there was a 2.5 cm irregular breach with exposed placenta and villous tissue in the posterior wall of the uterus. After removing intrauterine fetus and repairing the breach, there was still persistent intraperitoneal hemorrhage. The patient underwent subtotal hysterectomy finally.OutcomesPostoperative recovery was uneventful. The patient was discharged on the 8th day after operation.LessonsCombined efforts of specialists from ultrasound, imaging and gynecologist led to the successful diagnosis and management of this patient. We should be cautious about the occurrence of unscarred uterus rupture during pregnancy of the women with the disease of SLE and long-term glucocorticoid treatment. In IVF, we had better transfer one embryo for these patients with the history of SLE. Obstetricians should strengthen labor tests to detect early signs of UR of the patients with SLE and long term glucocorticoid treatment. Once UR is suspected, prompt surgical treatment is needed as soon as possible.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
