Central aortic wire confirmation for emergent endovascular procedures: As fast as surgeon-performed ultrasound.

Background: Uncontrolled hemorrhage is the leading cause of preventable death after trauma. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an evolving technique for controlling noncompressible torso hemorrhage. A challenge limiting REBOA use is the dependence on fluoroscopy for confirmation of intra-aortic positioning of a guide wire, a necessary component for safe and accurate balloon deployment.
