Long-term treatment results of 53 patients operated on thoracoabdominal aortic aneurisms and 7 patients, treated conservatively, were analyzed. Efficacy and choicelessness of operative treatment are demonstrated. 5-year general survival and complication free period for the operated patients were 0.59+/-0.09 and 0,67+/-0,1, correspondingly. 10-year survival and complication free period was 0.51+/-0.1 and 0,34+/-0,14. Unfavourable outcomes are cased by rupture or dissection of non-operated parts of aorta (40%); progressive coronary and carotid arteries occlusion (33,3%); septic complications (13,3%). Possibilities of long-term outcomes improvement after operative treatment of thoracoabdominal aortic aneurisms are proposed.
