Abstract

The world-wide impact of traumatic injury and associated hemorrhage on human health and well-being is significant. Methods to manage bleeding from sites within the torso, referred to as non-compressible torso hemorrhage (NCTH), remain largely limited to the use of conventional operative techniques. The overall mortality rate of patients with NCTH is approximately 50%. Studies from the wars in Afghanistan and Iraq have suggested that up to 80% of potentially survivable patients die as a result of uncontrolled exsanguinating hemorrhage. The commercially available resuscitative endovascular balloon occlusion of the aorta (REBOA) is a percutaneous device for the rapid control of torso hemorrhage in trauma. A compliant balloon is inserted via the femoral artery and inflated in the thoracic or abdominal aorta, providing inflow control of the abdomen, pelvis, or groin/lower extremities. Recent studies indicate that REBOA carries an inherent risk of aortic injury due to over-inflation and possible risk of aortic or iliac artery rupture. A new approach isto resolve the issue of balloon sizing and over-inflation. We propose a novel concept to be used in trauma facility for arterial occlusion to eliminate arterial injury and the risk of vascular rupture through real time balloon diameter profile measurements to ensure proper inflation. The proposed concept, called Smart Resuscitative Endovascular Balloon Occlusion (SREBO) will be novel in the following aspects: 1) It will have electrical conductance-based navigation technology to target the desired site of balloon deployment in the aorta, 2) The balloon can determine the time of proper inflation using electrical conductance catheter technology. This technology would eliminate the risk of arterial rupture and simplify the procedure in the trauma facility or medical clinics without significant training. The results can be displayed on a handheld device. This novel device has the potential to save civilians in trauma or soldiers injured on the battlefield.
