While REBOA’s origin dates back to the 1950s, recent advancements have made it more accessible and applicable in various clinical scenarios. REBOA has become increasingly utilized in not only the exsanguinating trauma patient but also in non-traumatic hemorrhage as a bridge to definitive hemostatic control. This article reviews the procedure and mechanism, clinical applications, and challenges associated with the REBOA. There are several challenges to consider when implementing the REBOA, particularly in procedural execution and patient selection. Determining the ideal candidates for REBOA remains inconclusive, with varying outcomes reported in different patient populations. Additionally, the potential for ischemic complications, such as visceral organ injury, end organ damage, and lower extremity ischemia, underscores the critical importance of procedural planning and ongoing monitoring. Partial and intermittent REBOA techniques have been introduced to mitigate ischemic complications associated with complete occlusion, but their efficacy and safety warrant further investigation. Beyond technical considerations, logistical and institutional factors pose as potential barriers to the effective utilization of REBOA, highlighting the importance of standardized training and a multidisciplinary approach when establishing a REBOA program. REBOA offers promising advancements in hemorrhage control, and the technology continues to evolve to address potential challenges and complications. Further research is imperative to delineate its optimal use and potential impact on patient outcomes.Keywords: traumatic hemorrhagic shock, REBOA, postpartum hemorrhage, partial REBOA, aortic occlusion, endovascular
