Extra-corporeal membrane oxygenation in aortic surgery and dissection: A systematic review

Table 1 “Participants, Intervention, Comparison, Outcome and Study Design” approach for the selection of clinical studies following systematic search

Participants	Patients undergoing major aortic surgery for aneurysmal disease or dissection
Intervention	VA-ECMO in patients requiring major aortic surgery for aneurysmal disease or dissection
Comparison	Comparison with those who did not need ECMO support
Outcome	If ECMO support made a difference
Study design	Prospective and retrospective clinical studies; case series and case reports

ECMO: Extra-corporeal membrane oxygenation; VA-ECMO: Veno-arterial extracorporeal membrane oxygenation.
