Aim:
To generalize our experience of step-by-step hybrid thoracoabdominal aortic replacement.
Material And Methods:
Twenty-three patients were enrolled who underwent staged hybrid treatment of thoracoabdominal aortic aneurysm. There were 5 (21.7%) women and 18 (78.3%) men aged 61.4±8.3 years (37-74 years). The first stage was proximal debranching, the second - distal (abdominal) procedure and the third - stenting of the thoracoabdominal aorta.
Results:
There were no any complications after proximal debranching and aortic stenting. Abdominal debranching was followed by lethal outcome in 3 (13.0%) patients and early postoperative occlusion of the prosthesis brunch in 3 out of 87 cases.
Conclusion:
Staged approach for hybrid surgical treatment is optimal solution, especially in high risk patients. In our opinion no necessity for cardiopulmonary bypass is the main advantage of this technique.
