Abstract:
Objective To retrospectively analyze perioperative and early outcomes after Sun's procedure of type A aortic dissection patients with different tear size ratia.Methods To retrospectively analyze the general information of 120 patients with acute Stanford type A aortic dissectiontreatedin our center from November 2014 to December 2016.Patients were divided into three group according to proximal and distal tear sizeratio(PDTSR):35 patients in Group A(PDTSR≥2),44 patients in Group B (1/2 ＜ PDTSR ＜ 2)and 41 patients in Group C (PDTSR ≤ 1/2).Retrospectively reviewed the data of perioperativeand follow-up period.Results Preoperative mortality was significantly higher in Group A (37.1％ vs.2.3％ vs.2.4％;P ＜ 0.001).Preoperative morbidity higher in Group A,but there was no significant difference.Ventilator support of duration ＞ 5 days in Group A is significantly higher in Group A (P =0.006).Three-month closure rate of false lumen was higher in Group A (85.0％ vs.65.0％ vs.72.7 ％,P =0.263).Proximal tear significantly larger than distal tear was found associated with preoperative death in logistic regression analysis.Conclusion Acute type A aortic dissection patients with larger proximal tear size need more urgent surgery to fix the dissection.Sun's procedure was an effective way to cure type A aortic dissection,while patients with relatively larger distal tears need more strict postoperative follow-up.
