Bolshak O. Reconstructive operations on an ascending aorta at her poststenotic dilation and concomitant aortic valve replacement

Dissertation is devoted to studying the problems of the treatment of patients with diseases of the aortic valve and the dilation of the ascending aorta, the development, validity and use of the most effective methods of treatment of patients with this pathology. The clinical material is based on a study of 529 adult patients with acquired aortic valvular diseases, which in the period from 1996 to 2014 it was performed aortic valve replacementnttt in combination with the correction of the poststenotic dilation of ascending aorta. Poststenotic dilation of the ascending aorta in 111 patients developed an original method to correct wrapping of the ascending aorta, allowing the base of the aorta and then up round by round shrouded ascending aorta, fixing tours together. Hospital mortality was 0,9 %. The implemented methodology wrapping of the ascending aorta is already allowed in the hospital stage significantly improve morphometry of the ascending aorta and to stabilize its diameter in the long term. When the techniques were no technical difficulties, complications. Method of low-traumatic, economic feasibility, possible to reduce the use of donor blood components, and in 36,0 % of cases, even completely eliminate the use of donor blood components throughout the hospital stage. Method wrapping of the ascending aorta has significantly improved the condition of patients in the long term, putting them in 85,8 % of cases in the I-II functional classes according to the classification of the New York Heart Association, and to avoid repeated interventions in the ascending aorta.
