Abstract

Hemorrhagic shock due to polytrauma is a life-threatening condition, requiring immediate diagnosis of the bleeding site and determination of an appropriate hemostatic procedure. Intra-abdominal injuries and pelvic fractures are major causes of massive hemorrhage, although the appropriate hemostatic procedures are different for each injury. We present a case of intraperitoneal rupture of the urinary bladder associated with pelvic fracture, in which urine extravasation into peritoneal spaces mimics intra-abdominal hemorrhage. A 33-year-old man with a known case of schizophrenia attempted suicide by jumping down from the 4th floor of his apartment (approximately 10 meters in height). He was in a state of shock on arrival. Focused assessment with sonography for trauma (FAST) showed fluid collection around his spleen only but not the perivesical space. Pelvic X-ray showed multiple pelvic fractures. We suspected the patient was in a state of hemorrhagic shock due to intra-abdominal hemorrhage and pelvic fracture. The patient's hemodynamic status did not respond to massive fluid infusion and blood transfusion, including eight units of packed RBCs transfusion. Resuscitative endovascular balloon occlusion of the aorta was performed; however, the patient's hemodynamic status did not recover. We performed an emergency laparotomy to control the suspected intra-abdominal hemorrhage. In peritoneal space, we found a large amount of non-bloody fluid. The liver, spleen, and bowels were not injured, whereas the urinary bladder was ruptured, indicating the correct diagnosis was intraperitoneal rupture of the urinary bladder associated with pelvic fracture. The ruptured urinary bladder wall was sutured, and temporary abdominal closure was performed. A contrast-enhanced CT performed after the laparotomy showed massive hemorrhage around the pelvic fracture. After arrival at the angiography room, the patient became bradycardia, and the pulsation at the carotid artery was not palpable. We performed cardiopulmonary resuscitation; however, the patient died eventually. Intraperitoneal rupture of the urinary bladder would mimic an intra-abdominal hemorrhage. Therefore, a comprehensive diagnostic-treatment approach such as a hybrid ER system would be beneficial for early and accurate diagnosis.
