OBJECTIVES: In the past decade, progress in cardiovascular technology has been incorporated into the surgical treatment of acute type A dissection resulting in remarkable improvement. Factors in this progress encompass rapid noninvasive diagnosis, intraoperative introduction of aprotinine, surgical glue, sealed grafts, and refined surgical technique. The objective of this study is to identify which factors contributed to the improvement of the surgical outcome of acute type A dissections. METHODS: Between January 1989 and February 2001, 78 consecutive patients had emergency surgeries for acute type A dissection. The initial 31 patients (group I) received preoperative angiography, when possible. Since 1996, the next 47 patients (group II) have received noninvasive rapid diagnosis with hemostatic surgical management. This included aggressive proximal resection and judicious use of gelatin resorcine formol glue and felt strips. Between the two groups, in-hospital mortality and morbidity, incidence of neurological complications, late survival and cardiovascular events were compared. Risk factors for in-hospital death were investigated with univariate and multivariate analysis. RESULTS: The in-hospital mortality was significantly improved in group II (4.3%) compared with group I (29.0%). Overall mortality was 14.1%. Multivariate analysis revealed preoperative limb ischemia and delayed timing of operation (> 3 hours after arrival) as independent risk factors for in-hospital death. Late survival at 5 years was 61.5+/-7.5%. Between the two groups there was no significant difference in late survival or cardiovascular events. CONCLUSIONS: Immediate surgical intervention, using rapid noninvasive diagnosis with hemostatic management, substantially improves the surgical outcome of acute aortic dissection.
