Optimal circulatory arrest temperature for total aortic arch replacement: outcomes of neurological complications.

Background: The optimal hypothermic circulatory arrest (HCA) temperature during total arch replacement (TAR) and the impact of HCA temperature on postoperative neurological complications are still uncertain.

Objective: The aim of this study is to explore the impact of HCA temperature on short-term postoperative outcomes, especially neurological complications, for patients who undergo TAR.

Methods: We retrospectively analyzed data of 2351 patients who underwent TAR at one of seven selected aortic centers from January 2016 to June 2023.

Clinical outcomes of the type II hybrid procedure for the repair of extensive aortic arch pathology.

Background: Type II hybrid arch repair (HAR) has been used for the repair of extensive aortic arch pathology. The aim of this study was to retrospectively analyze single-stage hybrid treatment involving replacement of the ascending aorta, arch debranching, and zone 0 stent graft deployment.

Methods: We retrospectively analyzed clinical data from 41 patients with acute and chronic aortic disease who underwent a type II hybrid arch procedure at Beijing Anzhen Hospital and Beijing Chaoyang Hospital from January 2020 to August 2022.
