Uterine rupture (UR) during pregnancy is an obstetric emergency that could determine poor maternal and neonatal outcomes. There are many factors that could increase the risk of UR, such as a previous myomectomy. The aim of this study is to evaluate the role of a previous myomectomy in a spontaneous UR in pregnancy.

A 33-year-old primigravida comes to our obstetric emergency room for pelvic pain at 29 weeks of gestation. In her medical history, there were two previous surgical operations of abdominal myomectomy, one in 2015 and one in January 2021 (6 months before conception). After 34 minutes, a pubo-subumbilical longitudinal laparotomy was performed for pathological decelerations in the cardiotocography. In the peritoneal cavity, there was 500 mL of blood serum liquid. The right arm and shoulder of the fetus were extending out of the uterus across a breach of 5 cm near the right tubal corner. A corporal incision was performed, and a healthy baby was born and moved to neonatal intensive unit care.

A UR can occur at any stage of pregnancy, mostly during the third trimester of pregnancy. Risk factors that increase the incidence of a uterine rupture after myomectomy include a short period (i.e., <12 months) between the myomectomy and conception, the opening of the endometrial cavity, and large myomas (with a maximum diameter above 4 cm). Uterine rupture during pregnancy after abdominal myomectomy seems to be less frequent than after a laparoscopic one.

Uterine rupture is an obstetric emergency; it is mandatory to consider this eventuality in pregnancy, particularly in the third trimester, if there was a previous laparoscopic myomectomy in the anamnesis of the patient.

Uterine rupture is a serious obstetric emergency, a severe event, and a serious threat to maternal and fetal life. It is a rare and not well characterized by the fact that multiple operations of uterine cavities contribute to uterine rupture during pregnancy. Atypical uterine rupture is easily misdiagnosed as other obstetric or surgical diseases. In current guidelines, abdominocentesis is a contraindication for late pregnancy. Therefore, the cases presented in this report provide new ideas for clinical diagnosis and treatment of uterine rupture.

Case 1, a 34-year-old woman (gravida 5, para 2), 32 wk and 4 d of gestation, presented with acute upper abdominal pain for 8 h with nausea and vomiting. Computed tomography (CT) revealed pelvic and abdominal effusion. We extracted 3 mL unclotted blood from her abdominal cavity. An emergency caesarean section was performed. A uterine rupture was found, and the fimbrial portion of the left fallopian tube was completely adhered to the rupture. The prognosis of both the mother and the infant was good. Case 2, a 39-year-old woman (gravida 10, para 1) at 34 wk and 3 d of gestation complained of persistent lower abdominal pain for half a day. Her vital signs were normal. CT revealed a high probability of pelvic and abdominal hemoperitoneum. We extracted 4 mL dark red blood without coagulation. An emergency laparotomy was performed. Uterine rupture was identified during the operation. Postoperative course in both the mother and infant was uneventful.

For pregnant women in the second or the third trimester with persistent abdominal pain, abdominal effusion, fetal distress and even fetal death, the possibility of uterine rupture should be highly suspected. CT can identify acute abdominal surgical or gynecological and obstetric diseases. Abdominocentesis is helpful for diagnosing and clarifying the nature of effusion, but its clinical value need to be confirmed by further clinical studies.
