Abstract

Background: Conventional surgical treatment of Stanford type A acute aortic dissection (AAD) is associated with considerable in-hospital mortality. As regards very elderly or high-risk patients with type A AAD, some may meet the criteria for less invasive surgery likely to prevent the complications associated with aortic replacement.

Methods: We have retrospectively analyzed a cohort of patients admitted to our center for Stanford type A AAD and having undergone surgery between 2008 and 2012. The outcomes of the patients having had an aortic replacement under cardiopulmonary bypass (group A) have been compared with the outcomes of the patients who underwent off-pump wrapping of the ascending aorta (group B).

Results: Among the 54 patients admitted for Stanford type A AAD, 15 with a mean age of 77 years [46 to 94] underwent wrapping of the aorta. Regarding the new standard European system for cardiac operative risk evaluation (EuroSCORE II), the median result in our group B patients was 10.47 [5.02 to 30.07]. In-hospital mortality was 12.80% in group A and 6.6% in group B (p=0.66). For patients who underwent external wrapping of the ascending aorta, follow-up mortality rate was 13.3% with a median follow-up of 15 months [range 0 to 47].

Conclusions: The gold standard in cases of Stanford type A AAD consists of emergency surgical replacement of the dissected ascending aorta. In some cases in which the aortic root is not affected a less invasive surgical approach consisting of wrapping the dissected ascending aorta can be suggested as an alternative.
