Cannula Placement for Cerebral Protection Without Circulatory Arrest in Patients Undergoing Hemiarch Aortic Aneurysm Repair

Abstract Background Aortic aneurysms involving the proximal aortic arch, which require hemiarch-type repair, typically require circulatory arrest with antegrade cerebral perfusion. Left carotid antegrade cerebral perfusion (LCP) via distal arch..

Validation of a new model of selective antegrade cerebral perfusion with circulatory arrest in rats

Abstract Background Selective antegrade cerebral perfusion (SACP) is adopted as an alternative to deep hypothermic circulatory arrest (DHCA) during aortic arch surgery. However, there is still no preclinical evidence to..

Prolonged Periods of Antegrade Cerebral Perfusion Are Safe During Elective Arch Surgery

Abstract Background Cerebral circulatory arrest times >40 minutes during  have previously been shown to be associated with increased morbidity and mortality. The purpose of this study was to redefine what would..

Aortic root surgery with circulatory arrest: Predictors of prolonged postoperative hospital stay

Abstract Objective Little is known about the outcomes of  operations that involve inducing hypothermic circulatory arrest for relatively extensive proximal . We attempted to identify predictors of postoperative hospital length of stay..

Does moderate hypothermia really carry less bleeding risk than deep hypothermia for circulatory arrest? A propensity-matched comparison in hemiarch replacement

Abstract Background Moderate (MHCA) versus deep (DHCA) hypothermia for circulatory arrest in  has been purported to reduce  and bleeding complications, although there are limited data supporting this claim. This study aimed to..

Deep hypothermic circulatory arrest or tepid regional cerebral perfusion: impact on haemodynamics and myocardial integrity in a randomized experimental trial

Abstract OBJECTIVES Organ protective management during aortic arch surgery comprises deep hypothermic (18°C) circulatory arrest (DHCA), or moderate hypothermia (28°C/ ‘tepid’) with regional cerebral perfusion (TRCP). The aim of this..
