abstract: OBJECTIVE
  To summarize the clinical study of modified total aortic arch replacement and stent elephant trunk technique treatment to patients with DeBakey I thoracic aortic dissection.
  
  
  METHODS
  From January 2006 to October 2010, 101 cases of DeBakey I aortic dissection were treated by modified total arch replacement and stent elephant trunk technique, in which emergency surgery for 73 cases. There were 76 male and 25 female patients, aged from 21 to 77 years with a mean of (49 ± 8) years. Intraoperative ascending aortic replacement in 31 cases, Bentall procedure in 29 cases, Wheat procedure in 7 cases, David procedure in 34 cases. At the same time stent elephant trunk in the left subclavian artery corresponding position was windowed to rebuild the blood supply. Deep hypothermic circulatory arrest cerebral protection was completed by bilateral antegrade cerebral perfusion.
  
  
  RESULTS
  The mean cardiopulmonary bypass time was (212 ± 40) min, mean myocardial occlusion time was (95 ± 16) min, mean circulatory arrest time was (42 ± 8) min. Operative mortality was 1 case and hospital mortality was 5 case, which died of septicemia, acute renal failure and hemiplegia complicated with multiple organ failure. Compared with selective cerebral perfusion, the incidence of postoperative cerebral vascular accident and transient neurological dysfunction decreased. Seventy-six cases received aorta CTA before discharged, the closure rate of descending thoracic aortic dissection false lumen was 78.9%. Seventy-one patients were followed up for 5 to 49 months, 50 cases was reviewed by CTA, of which closure rate of descending thoracic aortic dissection false lumen was 88.0%, no late death and re-surgery.
  
  
  CONCLUSIONS
  The modified total aortic arch replacement and stent elephant trunk technique treatment for patients with DeBakey I thoracic aortic dissection was safe and effective, with less postoperative complications.
