Aortic pseudoaneurysms after acute Type A aortic dissection (ATAAD) repair have been reported as high as 10-24% and surgical treatment is usually recommended. The objective of this article is to examine the safety and efficacy of a conservative approach to aortic pseudoaneurysm and to compare this approach to standard surgical treatment. We retrospectively examined 39 patients who had an aortic pseudoaneurysm after ATAAD surgery in order to examine outcomes (baseline characteristics, presentation and freedom from aortic events and mortality). We initially identified 31 patients treated conservatively (CT). After close follow up, 5 of them were operated so 13 patients were treated surgically (ST) and analyzed at a long-term follow-up while 26 were in the conservative group. Mean follow- - up of the whole cohort was 7.9 ± 5.9 years. The freedom from aortic-related mortality at 1, 5, and 10 years was 100%, 83.3% and 72.9% for the ST group and 95.8%, 77.3%, and 77.3% for the CT group (P = 0.35). A conservative approach to aortic pseudoaneurysms could be justified in asymptomatic patients. A close follow-up by a dedicated aortic clinic is mandatory so that patients are referred for surgery when necessary.
