INTRODUCTION
Aortic arch surgery presents a challenge in neonates in terms of organ
protection. Deep hypothermic circulatory arrest (DHCA) has so far been
the most common adjunctive support technique. While this technique
protects vital organs due to hypothermia, it has the added technical
advantage of removing blood from the operative field (1). Though DHCA
provides time-limited protection, it is not devoid of damaging effects
(2). Though still a mainstay in congenital heart surgery, DHCA is
associated with poor neurodevelopmental outcome (3). Alternative
perfusion techniques have, therefore, been developed, such as antegrade
cerebral perfusion (ACP) combined with moderate hypothermic circulatory
arrest (MHCA) of the lower part of the body (4). This study sought to
evaluate the feasibility and efficacy of combined continuous cerebral
and myocardial selective perfusion strategy (CCMSP) as applied in our
center.
