Abstract：Objective To summarize the experience of stented elephant trunk implantation combined with left subclavian artery (LSCA)-left common carotid artery (LCCA) transposition treating acute Stanford type B dissection with distal aortic arch involvement.Methods A retrospective study was performed in 27 patients with acute Stanford type B dissection with distal aortic arch involvement who had elephant trunk implantation combined with LSCA-LCCA transposition from April 2011 to April 2015 in Department of Cardiac Surgery,Beijing Anzhen Hospital,Capital Medical University.Basic clinical data and surgical date were analyzed.Results There was no in-hospital death.Mean cardiopulmonary bypass time was (129 ± 31)min(85-193 main);mean aortic cross-clamp time was (58 ± 33) min (24-147 min);mean selective antegrade cerebral perfusion time was (25 ± 6) min (14-41 min).Mechanical ventilation time was ≤ 24 h in 25 patients.Mean follow-up time was (32 ± 12)months (18-66 months).Concomitant procedures included aortic valve replacement + coronary artery bypass graft in 1 patient,coronary artery bypass graft in 1 patient and isolated left vertebral artery-LCCA transposition in 3 patients.There was 1 death during follow-up;1 patient had thoracoabdominal aortic replacement and recovered well.CT showed that the distal stent-graft false lumen closure rate was 88.9％ (24/27).Conclusion Stented elephant trunk implantation with LSCA-LCCA transposition has a good curative effect on acute Stanford type B dissection with distal aortic arch involvement.
