ABSTRACT Introduction: The objectives of this study were to investigate the main treatment strategies and long-term follow-up results of aortic dissection surgery after open-heart surgery (ADSOHS) and to analyze the risk factors that cause ADSOHS. Methods: One hundred thirty-seven patients with ADSOHS hospitalized in our hospital from January 2009 to December 2018 were selected as the research object. Long-term follow-up results, complications, mortality, and changes of cardiac function before and after operation were used to explore the value of Sun’s operation. Results: The length of stay in intensive care unit of these 137 patients ranged from 9.5 to 623.75 hours (average of 76.41±97.29 hours), auxiliary ventilation time ranged from 6.0 to 259.83 hours (average of 46.16±55.59 hours), and hospital stay ranged from six to 85 days (average of 25.06±13.04 days). There were seven cases of postoperative low cardiac output, 18 cases of coma and stroke, and six cases of transient neurological dysfunction. A total of 33 patients died; 19 patients died during the perioperative period, 18 died during Sun’s operation and one died during other operation; and 14 patients died during follow-up (January 2021), 12 cases of Sun’s operation and two cases of other operations. Conclusion: ADSOHS treatment strategy is of high application value, and the risk of neurological complications and mortality is low. The main risk factors are postoperative low cardiac output, coma, stroke, and transient neurological dysfunction. The extracorporeal circulation time is relatively long. Short- and long-term follow-up effects are good, and it is worthy of clinical promotion.
