Objective To investigate the surgical experience, best timing of operative intervention, technique and clinical effects of surgical treatment for acute Stanford type A aortic dissection. Methods The clinical material, method of operation and follow-up results were retrospectively reviewed for 29 patients with acute Stanford type A aortic dissection in latest 8 years. The main principle of surgical therapy in Stanford type A aortic dissection was resecting the partial aorta of intimal tear to prevent aortic rupture, repairing the intimal tear and replacing or reconstructing the aorta by composite graft, and simultaneously dealing with the heart valve and myocardial ischemia disease. Results Emergency surgery was performed in 13 cases, and sub-emergency surgery for 16 cases. There were 2 cases (69%) early postoperative death. One patient died of severe arrhythmia after emergency surgery, and another case died of multiorgan failure after operation. After operation 6 cases needed to be re-operated for bleeding, 3 cases developed lung infection and respiratory failure, 4 cases delayed waking, 2 cases occurred acute renal failure and one case occurred gastrorrhagia, they all were treated appropriately and recovered. Twenty-four cases? (889%) were followed up for 23.6±101 months. One case died after 16 months postoperatively due to endocarditis and cerebral hemorrhage. One case was recorded of sudden death in 26 months. Currently other patients were still healthy as the normal person. Conclusion Early-time surgical treatment is the key factor for acute Stanford type A aortic dissection to reduce the mortality. Procedures chosen must depend on the location of intimal tear, involved extension, and the condition of aortic valve and aortic root. It is principle as simplifying operation and good effects of treatment.
