Deployment of second-generation resuscitative endovascular balloon occlusion of the aorta for unresponsive hypotension in a polytrauma patient.

Noncompressible hemorrhagic control remains one of the most challenging areas in damage control medicine and continues to be a leading cause of preventable death. For decades, emergency thoracotomy or laparotomy and aortic cross clamping have remained the gold standard intervention. Recently, there has been a movement toward less invasive techniques for noncompressible hemorrhagic control, such as resuscitative endovascular balloon occlusion of the aorta (REBOA). The REBOA technique involves inflation of an endovascular balloon within the abdominal aorta proximal to the vascular injury to temporarily inhibit bleeding. Although the literature is robust on this new technique, skepticism remains about whether REBOA is superior to aortic cross clamping, as it has been associated with complications including organ and limb ischemia, limb amputation, femoral aneurysm, and thrombosis.
