Aim — to analyze mid-term efficacy of frozen elephant trunk (FET) procedure in patients with thoracic aortic aneurysms. Material and methods. There were 10 FET procedures in patients with thoracic aortic aneurism for the period 2012—2018. All interventions were carried out under moderate hypothermia (25—28 °C), circulatory arrest and unilateral cerebral perfusion through innominate artery. Results. Mean size of stent-graft deployed was 28±5.5 mm (range 22—40 mm). Distal zone of stent-graft deployment was below Th9 in 70% of cases (range Th7—Th11). Proximally stent-graft was deployed within Z0—Z3 areas, predominantly in Z3-zone (80%). There was no 30-day and in-hospital mortality. Overall 5-year survival rate was 80%, freedom from redo surgery — 100%. Conclusion. FET procedure is effective surgical treatment of thoracic aortic aneurysms with satisfactory mid-term outcomes.
