Publications presenting algorithms for REBOA patient selection (2015–2022)

Year	First author (institution)	Data sources cited	Methodology	Scope limitations	Comments on early CFA access?	Contraindications to REBOA	Criteria for REBOA patient selection
2018	Brenner (ACSCOT and ACEP)24	Yes	Joint policy statement based on published data, best evidence, and expert opinion	None	No	None specified.	Traumatic life-threatening hemorrhage below the diaphragm in patients in hemorrhagic shock who are unresponsive or transiently responsive to resuscitation. Patients arriving in arrest from injury.
2019	Borger van der Burg (multicenter)7	No	Delphi consensus (3 rounds, 43 experts responding)	None	Yes	Major bleeding in the neck or proximal to the left subclavian artery.	Traumatic abdominopelvic hemorrhage. Trauma patients with initial SBP <90 who do not respond to resuscitation. Any trauma victim with ATLS class IV hypovolemic shock.
2020	Glaser (JTS)8	Yes	Military guidelines	Military	No	Severe blunt chest injury. Profound shock or traumatic arrest due to penetrating neck, chest, or extremity injury.	SBP <90 and transient or no response to initial resuscitation in blunt trauma or penetrating abdominal/pelvic/junctional injury. Traumatic arrest (blunt or penetrating) based on injury location and CPR time.
2020	Brenner (UC Riverside and Shock Trauma)22	Yes	Not specified	Traumatic cardiac arrest	Yes	None specified.	Blunt or non-thoracic penetrating injury. Hemorrhage location unknown or below the diaphragm. Consider with hemorrhage location in the thorax in combination with resuscitative thoracotomy.
2020	Ordoñez (Cali, Colombia)16 17	Yes	Institutional algorithm	None	Yes	None specified.	Non-compressible torso hemorrhage. Blunt or penetrating mechanism. SBP <90 and transient responder to resuscitation.
2022	Inaba (WTA)20	Yes	Society consensus	None	Yes	Major thoracic vascular injury.	Sustained hypotension refractory to resuscitation.
2021	Johnson (multicenter)25	Yes	Consensus after multicenter observational study	None	Yes	Thoracic hemorrhage.	SBP <90 and partial or non-responder.
2021	Castellini (Milan, Italy)26	Yes	Not specified	None	No	Suspicion of thoracic aorta injury.	Hypotensive trauma patients with suspected torso hemorrhage. Non-responders to resuscitation. Positive FAST or positive pelvic X-ray.
2021	Hadley (Denver Health)15	Yes	Institutional algorithm	None	No	Thoracic hemorrhage.	SBP <80 and hemorrhage location. Traumatic arrest with pelvic or extremity hemorrhage.
2022	Nagashima (Japan)27	Yes	Not specified	None	Yes	Near/recent cardiac arrest. Possible aortic injury.	Hypotensive partial or non-responder.
