About

This study seeks to evaluate the feasibility of a Abdominal Aortic Balloon Occlusion of the Aorta (AAJT-S) in exanguinating trauma patients with non-compressible truncal haemorrhage in the emergency room and the pre-hospital setting.

Full description

Much like REBOA, AAJT-S can potentially stop blood flow distal to the device and therefore improve proximal aortic perfusion, minimize haemorrhage and stabilize patients until definite surgical repair/bleeding control is feasible. In contrast to REBOA, there is no need of femoral access and therefore, appropriate training is easily achieved.

This study seeks to gather further information on the benefits and potential harms of this intervention on a multicentre level.
