REBOA to the Rescue: Successful Endovascular Resuscitation of Methemoglobinemia-Induced Cardiac Arrest

Abstract

REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) is an endovascular occlusion device commonly used to temporize bleeding due to traumatic non-compressible torso hemorrhage. This case report presents the successful utilization of REBOA in the resuscitation of a critically ill trauma patient that presented to the emergency department status post motor vehicle collision, later found to have methemoglobinemia. The REBOA was placed as part of a catch-all trauma workup following cardiac arrest after intubation. The timely placement of the REBOA resulted in a return of spontaneous circulation within 30 seconds of balloon inflation. While it is not a definitive treatment of methemoglobinemia, REBOA allowed us to successfully resuscitate the patient until final diagnosis and treatment of the underlying methemoglobinemia could be made. The patient would go on to regain full neurologic function. We believe that this is the first reported resuscitation of a patient with methemoglobinemia utilizing the REBOA device.
