Impact of Reimplantation Technique of Supra-Aortic Branches in Total Arch Replacement on Stroke Rate and Survival: Results From the ARCH Registry

Schoenhoff and colleagues evaluated the impact of reimplantation techniques of the supra-aortic branches, en bloc or separate, on neurological complications following total arch replacement. In a study of 3345 patients enrolled to the ARCH registry, the authors found that separate reimplantation of the supra-aortic branches increased the risk of neurological complications in the full cohort but not in a comparison of 461 matched patient pairs. Implantation technique did not influence early mortality or late survival.
