Bränsström, 2019 Animal: Comparative animal model study on 12 Transition from AAJT to REBOA was feasible with
the transition from AAJT to REBOA hemodynamic support.
Bränsström, 2022 Animal: Comparative animal model study 6 Treatment with the AAJT required one seventh of the
with REBOA. amount of crystalloids compared to REBOA. AAJT
subjects required vasopressor support upon deflation.
Do, 2019 Animal: Comparative animal model study 6 The AAJT extended survival time, decreased blood loss,
with open pelvic packing and preperitoneal achieved higher tamponade pressure, and improved
balloon tamponade. survival. Fifty percent of the subjects sustained organ
injuries, and 66% died from reperfusion injuries within
10 minutes of the release of the AAJT.

AAJT = abdominal aortic and junctional tourniquet; CMT = combat medic technician; HEMS = Helicopter Emergency Medical Services;
REBOA = resuscitative endovascular balloon occlusion of the aorta; TCA = traumatic cardiac arrest.
