Positive Seatbelt Sign with Avulsed Leiomyoma following Motor Vehicle Accident Leading to Hemoperitoneum

A case of severe hemorrhagic shock caused by traumatic avulsion of uterine fibroid

Case presentation

A 40-year-old woman was injured in a motor vehicle accident. Physician-staffed helicopter emergency medical service (HEMS) was dispatched, and after the HEMS physician performed thoracostomy and tracheal intubation to relieve the tension pneumothorax and hemorrhagic shock, her carotid artery became unpalpable. The physician then decided to perform prehospital resuscitative thoracotomy. Immediately after arriving at the hospital, an emergency laparotomy was performed. Intraoperative findings showed that a huge uterine fibroid had been avulsed from the uterine wall, and we performed temporary hemostasis by extraction of the avulsed tumor and application of packing to the pelvic cavity. She was transferred to a rehabilitation hospital 42 days after the operation.

Conclusion

The injury mechanism in this case was considered a “submarine effect.” This was an extremely rare case in which the acute care surgeon and a gynecologist collaboratively employed a damage control strategy to deal with impending cardiac arrest.

Hypovolaemic shock due to intra-abdominal haemorrhage from multiple uterine fibroids

Intra-abdominal bleeding due to uterine fibroids is extremely rare, and preoperative diagnosis is difficult. Herein, we report a case of preoperatively diagnosed hypovolaemic shock due to intra-abdominal haemorrhage, in which fatal sequelae were prevented. A 46-year-old non-pregnant woman was brought to the hospital with a sudden-onset lower abdominal pain. On admission, she was in shock, and abdominal CT showed severe intra-abdominal haemorrhage. Since bleeding from uterine fibroids was suspected, an emergency simple total hysterectomy was performed, and her condition became stable after the operation. Intra-abdominal haemorrhage with hypovolaemic shock requires prompt surgical intervention. Although it occurs very rarely due to bleeding from uterine fibroids, imaging shows large fibroids; if the patient is not pregnant, bleeding from the fibroids should be considered.
