Objective To summanrize the operative method and follow-up data of total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta (Sun's procedure) for acute Stanford type A aortic dissection.Methods Between August 2004 and March 2012,73 patients with acute type A aortic dissection underwent this procedure.60 males and 13 females ranging in age from 26 to 79 years (mean age,49,6 years).Right axillary or femoral artery cannulation was routinely used for cardiopulmonary bypass.Cerebral protection was achieved by bilatero-antegrade or selected hrain perfusion.The stented elephant trunk was implanted throuugh the aortic arch under hypothermic circulatory arrest.The stented elephant trunk was a 10cmlong self expandable graft.Patent false lumina were evaluated using computed tomography 3 months and once each year after discharge to evaluate the postoperative time course of the residual false lumen.Results Mean cardiopulmonary bypass time was (248.1±69.8)min,and selected cerebral perfusion time was (38.2±10.5)min.Hospital morality was 6.85 ％ (5/73).Thrombus obliteration of the residual false lumen in the descending thoracic aorta was observed in 9 1.7％ of the aortic dissections 3 months postoperatively.The mean follow-up time was(36.4 ± 31.6)months (range,2 to91 months).Survival at 1,5,7 years was 97％,87％ and 81％,respectively.Conclusion Total aortic arch replacement combined with transaortic stented paft implantation into the descending aorta is an effective treatment and n more promising choice for acute type A aortic dissection.
