A 41-year-old woman with blunt abdominal trauma due to a motor vehicle accident presented to our emergency department. The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration (5 cm) of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of >1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.
