The increasing use of antegrade cerebral perfusion (ACP) during aortic arch surgeryhas corresponded with a trend toward warmer target temperatures for hypothermic circulatory arrest. This meta-analysis examined the clinical outcomes using colder or warmer circulatory arrest targets with ACP.
Electronic searches were performed using four databases from their inception to February 2017. Comparative studies of adult patients who underwent aortic archoperations using ACP at different circulatory arrest temperatures were included. Data were extracted by 2 independent researchers and analyzed according to predefined end points using a random-effects model.
