On-site placement of resuscitative endovascular balloon occlusion of the aorta (REBOA) in a hemorrhagic shock patient: A successful endeavor involving long-distance air transport

Abstract

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is primarily utilized in traumatic non-compressible torso hemorrhage. We present a 49-year-old male with hemorrhagic shock necessitating on-site REBOA placement on an island 986 km away from the nearest critical care center. The patient experienced sudden pain in the right costal margin and visited the local clinic where computed tomography revealed a massive intra-abdominal hemorrhage and a renal artery aneurysm. An emergency care physician was deployed via fixed-wing aircraft who positioned the REBOA on-site in the thoracic aorta. Partial balloon inflation (partial REBOA) and intermittent inflation/deflation (intermittent REBOA) was repeated throughout the 5-h return flight. Despite prolonged REBOA placement, no safety issues or ischemic complications were documented and parent artery occlusion was subsequently performed via interventional radiology at our facility. The patient was later discharged home in a good state of health. On-site REBOA placement is not only applicable to trauma but also internal hemorrhaging due to non-traumatic causes. Partial and intermittent REBOA successfully stabilized circulation, prevented organ ischemia and facilitated long-distance patient transport in the present case.
