Trends in Aortic Occlusion and How to Minimize the Risk of Complications in REBOA

Resuscitative endovascular balloon occlusion of the aorta (REBOA) increases proximal aortic pressure in order to maintain central organ perfusion pressure, and simultaneously regulates distal arterial flow by endovascular aortic occlusion, which is applied during subdiaphragmatic hemorrhage. This article briefly introduces the history of REBOA and discusses its potential effectiveness and harmfulness. The following sections mention the technical aspects of REBOA, and reconsider the term “REBOA” and “resuscitation.” The risks of aortic occlusion and ischemia-reperfusion injury have not been fully elucidated. The authors hope that REBOA can be used appropriately as a powerful option for the resuscitation of hemorrhagic patients and save the lives of as many patients as possible. The Japanese Society of Diagnostic and Interventional Radiology in Emergency, Critical Care, and Trauma will publish continuous medical education articles on REBOA as narrative review articles.
