Objective：To summarize the experiences of brachiocephalic artery conserved Sun’s procedures for the patients with bra－chiocephalic artery uninvolved complicated Stanford type A aortic dissection. Methods：From February 2013 to November 2013，4 pa－tients of innominate artery uninvolved complicated Stanford A aortic dissection were operated in our hospital. They were all males，with an average age of （45±16.02） years old. Two patients were operated in emergence while two others not. Right axillary artery cannulation was routinely used for cardiopulmonary bypass and selected cerebral perfusion was utilized when deep hypothermic circu－latory arrest. Replacement of ascending aorta was carried out for three patients，while replacement of noncoronary sinus and ascending aorta for one. Results：Cardiopulmonary bypass time was （220±58.21） min，the aortic occlusion time was （109.25±52.87） min，and selected cerebral perfusion time when deep hypothermic circulatory arrest was （53.75±29.24） min. The drainage in 24 h was （337.5±202.22） ml after operation. No coma and paraplegia was found in this group. No patient was re-operated. One patient suffered from noninvasive mechanical ventilation because of respiratory insufficiency. All patients were discharged home. CT exams before discharge confirmed a good result of surgery. All patients were follow-up for 1-10 months. They recovered well and no death occurred. Conclusion：Brachiocephalic artery conserved Sun’s procedures is good and safe for the patients with brachiocephalic artery uninvolved complicated Stanford A aortic dissection.
