Achieving good neurological outcome by combining decompressive craniectomy for acute subdural hematoma and transarterial embolization of intraperitoneal injured arteries for multiple severe trauma: a case report

A 22-year-old woman jumped from the 4th floor of her apartment in an attempt to commit suicide. Whole-body computed tomography showed multiple injuries, including right acute subdural hematoma, left hemopneumothorax, several fractures, intraperitoneal hemorrhage, and spleen injury. Her consciousness deteriorated rapidly, and her right pupil was dilated. Furthermore, she had unstable vital signs including blood pressure of approximately 70/40 mmHg, pulse about 150/minute, respiratory rate 25/minute, and percutaneous oxygen saturation of 90% on 10 L oxygen. Intratracheal intubation and insertion of a thoracostomy tube were performed in the emergency room. Due to concomitant brain herniation and hemorrhagic shock, simultaneous decompressive craniectomy for acute subdural hematoma and transarterial embolization of intraperitoneal injured arteries were performed in our hybrid operating room. Despite rapid blood transfusions, the blood pressure did not increase. After starting embolization of the injured arteries of the spleen, the blood pressure increased, thereby making it possible to remove the acute subdural hematoma, and hemostasis was then achieved. Four hours later, the acute subdural hematoma and intracranial pressure increased again, and re-operation was performed in the normal operating room. Cranioplasty and clavicular fracture reduction were performed 14 days later. She recovered enough to talk and walk, and her consciousness stabilized. Interviews with her and her family by a psychiatrist determined that abnormal behaviors had first appeared 2 months earlier. She was diagnosed with acute and transient psychotic disorders, and treatment was started. The patient was discharged home 1 month later with mild disability of her higher-order brain function.
