Short-and mid-term follow-up of surgical treatment of postoperative ascending aortic pseudoaneurysm

Abstract:

Postoperative pseudoaneuryms of the ascending aorta constitute a severe complication of cardiovascular surgery, developing in most cases after aortic valve replacement or myocardial revascularization surgery and after other procedures involving aortic manipulation, trauma and infections. Six consecutive patients with pseudoaneurysm of the ascending aorta were studied and operated on at the Department of Cardiovascular Surgery of the Hospital Hermanos Ameijeiras over a 7-year period. The variables mainly related with the diagnosis and surgical procedures, as well as the outcome and subsequent follow-up, were analyzed. A history of aortic valve replacement was present in 83.4% of patients; fever was the most prevalent symptom and pseudoaneurysms were most commonly located at the previous aortotomy site. Synthetic patch graft aortoplasty was the most frequently procedure used. In-hospital mortality was of 16.66% with a one-year survival of 66.66%.
