After excluding those with aggressive arch replacement (n = 168), cerebral malperfusion syndrome (n = 34), and indeterminable arch branch vessel dissection (n = 1), 276 patients with an acute type A aortic dissection without cerebral malperfusion syndrome who underwent hemiarch replacement comprised this study. Patients were then divided into those with arch branch vessel dissection (n = 133) and those with no arch branch vessel dissection (n = 143The Journal of thoracic and cardiovascular surgeryIs hemiarch replacement adequate in acute type A aortic dissection repair in patients with arch branch vessel dissection without cerebral malperfusion?PMC7935741K08 HL130614R01 HL141891R01 HL151776Fukuhara SPatel HJDeeb GMNorton ELKim KMYang BWu XfalseIs hemiarch replacement adequate in acute type A aortic dissection repair in patients with arch branch vessel dissection without cerebral malperfusion?<h4>Objective</h4>The study objective was to determine if hemiarch replacement is an adequate arch management strategy for patients with acute type A aortic dissection and arch branch vessel dissection but no cerebral malperfusion.<h4>Methods</h4>From January 2008 to August 2019, 479 patients underwent open acute type A aortic dissection repair.
