The authors analyse herein their experience gained in performing the operation of exoprosthetic repair of the ascending portion of the aorta in patients presenting with an ascending aortic aneurysm. This is followed by assessing the results in the remote period. Over the period of follow up from 2012 to 2016 a total of 23 interventions were performed. The average duration of postoperative follow up amounted to 27±9.4 (2–40) months. In the remote period we managed to obtain the data for 20 (90.1%) patients. The patients were interviewed by means of either remote or face-to-face consultations during which we performed assessment of the dimensions of the thoracic portion of the aorta by the findings of MSCT angiography of the aorta. Health-related quality of life was evaluated by means of the Short Form Health Survey Questionnaire SF-36.

No statistically significant changes of the aortic sizes were revealed in the remote period as compared with the findings at discharge from hospital. Neither were there repeat interventions related to the operation performed. According to the findings of the SF-36 questionnaire, patients mainly reported improved well-being as compared with that at discharge, including patients having endured coronary artery bypass grafting or prosthetic repair of the aortic valve.

Experience shows that using the technique of exoprosthetic repair of the ascending portion of the aorta makes it possible to eliminate dilatation with satisfactory remote results. However, fuller and more reliable assessment of the results requires further studies.

KEY WORDS: aorta, aneurysm of the ascending portion of the aorta, exoprosthetic repair.
