A case of hemorrhagic shock due to intercostal artery injury that occurred during initial trauma care with multiple displaced rib fractures and traumatic head injury
Abstract
Rib fractures can cause injury to some organs. We herein report a case of hemorrhagic shock due to intercostal artery injury that occurred during initial trauma care (ITC) treated by resuscitative thoracotomy (RT) and transcatheter arterial embolization (TAE) with multiple displaced rib fractures (RFs) and traumatic head injury (THI). A man in his 50s who was injured in a traffic accident was transferred to our institution by helicopter for emergency medical treatment. He underwent left thoracic drainage on site. On admission, he was diagnosed with multiple RF, THI, pelvic fracture and right humerus fracture. His D-dimer and fibrin degradation products (FDP) level were extremely elevated. However, contrast enhance CT (CECT) revealed no extravasation. At 2 h after arrival, massive hemorrhaging from his thoracic tube suddenly occurred and his blood pressure decreased to approximately 40s mmHg. CECT performed after volume resuscitation and massive transfusion revealed extravasation from the intercostal artery. Because his blood pressure could not be maintained by massive transfusion, we performed RT and TAE followed by RT. He then received intensive care and several surgical procedures were performed, including craniotomy for removal of hematoma, rib fixation and humerus fixation. He was transferred to another hospital for rehabilitation on day 63, with a GCS of 15. Hemorrhagic shock due to intercostal artery injury may occur at any time from arrival in cases with displaced RF, especially when complicated by THI.
