ObjectiveTo evaluate the short-term result of proximal lengthening grafted stent and modified innominate artery cannula for Stanford A aortic dissection. Method We retrospectively analyzed the clinical data of 21 patients with Stanford A aortic dissection in our hospital between December 2012 and January 2015. There were 16 males and 5 females at a mean age of 57 years. All 21 patients underwent total arch replacement with proximal lengthening grafted stent and modified innominate artery cannula invented by our center. Result The mean operation time of 21 patients was 187.0±31.1 minutes, the mean cardiopulmonary bypass time was 116.0±32.0 minutes, the mean aortic block time was 87.0±23.0 minutes, the mean selective cerebral perfusion (SCP) time was 23.0±3.9 minutes, the mean breathing machanical ventilation time was 19.0±6.0 hours, and the mean intensive care unit stay time was 3.0±0.9 days. All patients had a good recovery after surgery. There was no death or severe complications. ConclusionThe technique of total arch replacement with proximal lengthening grafted stent and modified innominate artery cannula for Stanford A aortic dissection is effective, easy, and safe. The short-term result is satisfying.
