Partial Resuscitative Endovascular Balloon Occlusion of the Aorta Aids in the Successful Non-Operative Management of a Life-Threatening Penetrating Liver Injury.

ABSTRACT

In recent years, isolated non-operative management of penetrating liver injuries has become the standard of care for the hemodynamically stable patient. However, when the patient becomes hemodynamically unstable, adjuncts such as resuscitative endovascular balloon occlusion of the aorta (REBOA) deployed in Zone 1 can be used to achieve complete aortic occlusion from the celiac axis down. Unfortunately, hemorrhage control through REBOA comes at the risk of deadly intra-abdominal ischemia. Partial REBOA (pREBOA) introduces the opportunity to make targeted changes in volume and thus titrate the amount of aortic occlusion in real-time to adequately manage hemorrhage while allowing some distal blood flow. This is a novel approach and one which may give providers more time to gain definitive hemorrhage control while minimizing the morbidity of ischemia. Here, we present a case of life-threatening penetrating liver injury that was successfully managed non-operatively with the assistance of p-REBOA.
