Aim. To assess results of Meshalkin National Research Medical Center and Tomsk National Research Medical Center in surgical treatment of DeBakey type I aortic dissection using hybrid technologies (“frozen elephant trunk”) compared with classical standard interventions. Material and methods. The study included patients operated on successively in the 2002-2010 timeframe with a diagnosis of acute and subacute DeBakey type I aortic dissection. A retrospective observational comparison of the surgical treatment results of patients (two groups) was performed: using standard surgical approaches (beveled anastomosis or aortic arch replacement using multi-branched prosthesis) and frozen elephant trunk (FET) intervention. The groups included 70 and 31 patients, respectively. Mortality and morbidity were evaluated in the postoperative period, the frequency of aorto-related events - during the observation period. Results. Mortality and the frequency of complications between the groups in the early and late postoperative periods did not differ. Aorto-related events of the groups in the long-term period differed statistically significantly in favor of hybrid interventions (p=0,005). Conclusion. The hybrid technology of thoracic aorta reconstruction using “frozen elephant trunk” type allows to make one-step reconstruction of the aorta during its multilevel lesion. Observation of patients in the long-term period allows us to announce of a longtime, stable result of surgical treatment in the absence of additional perioperative risks.
