Resuscitative endovascular balloon occlusion of the aorta.

The management of non-compressible torso hemorrhage can be problematic. Current therapy requires either open or interventional radiologic control of bleeding vessels and/or organs. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a new tool to stabilize patients in shock by achieving temporary inflow occlusion of non-compressible torso hemorrhage. This proactive technique represents a paradigm shift in achieving hemodynamic stability in patients as a bridge to definitive hemostasis. REBOA is applicable by trauma professionals, including emergency physicians, at the bedside in the emergency department, but its use needs to be considered within the context of available evidence and a robust system encompassing training, accreditation, multidisciplinary involvement and quality assurance. We review the evolving role of REBOA and discuss unanswered questions and future applications.
