Aim — to present current treatment modes for DeBakey type I aortic dissection, to compare their early and mid-term postoperative results, to evaluate predictors of negative aortic remodeling after surgery. Material and methods. Retrospective cohort analysis included 78 patients with DeBakey type I aortic dissection who underwent surgical treatment in 2009—2017. Patients were divided into 3 groups depending on type of intervention: group I (n=22) — Elephant Trunk procedure, group II (n=29) - hybrid interventions, group III (n=27) — proximal aortic replacement alone. Early postoperative results and aortic remodeling in mid-term postoperative period were compared. Results. There were no significant differences in postoperative morbidity, in-hospital mortality and freedom from aortic death. However, 7 patients were lost for follow-up in group III. Analysis of false lumen patency showed results in favor of more aggressive approach (groups I and II) with significantly higher rate of false lumen thrombosis in segments 1 and 2 (p<0,001 and p=0,004 respectively). Freedom from negative aortic remodeling was also significantly higher in groups I and II. Risk factors of patent false lumen were residual fenestration, large volume of false lumen in segment 2, dissection of supra-aortic vessels and connective tissue disorders. Risk factors of negative aortic remodeling were connective tissue disorders, patent false lumen and dissection of supra-aortic vessels. Conclusion. Advanced surgical approach (Elephant Trunk procedure or hybrid interventions) should be preferred for DeBakey type I aortic dissection.
