Results of Proximal Arch Replacement Using Deep Hypothermia for Circulatory Arrest: Is Moderate Hypothermia Really Justifiable?

摘要

ObjectiveThe use of selective cerebral perfusion with warmer temperatures during circulatory arrest has been increasingly utilized for arch replacement over concerns regarding the safety of deep hypothermic circulatory arrest (DHCA). However, little data actually exists on outcomes following arch replacement and DHCA. This study examines modern results with DHCA for proximal arch replacement to provide a benchmark for comparison against outcomes with lesser degrees of hypothermia.
