Wrapping in Ascending Aortic Aneurysms as an Alternative for Replacement: Is It Beneficial?

BACKGROUND
 Prosthetic replacement of aneurysms of the ascending aorta is the gold standard in terms of long-term stability. Wrapping seems to be a less invasive procedure. It has not yet been shown if it is as safe in terms of long-term outcome.


METHODS
 We present a single-center analysis of our experience over 13 years. We retrospectively analyzed data from patients who received either aortic prosthetic wrapping (AW) or aortic prosthetic replacement (AR) with or without aortic valve replacement and assessed them through phone calls. We used propensity score matching to adjust the baseline of the groups.


RESULTS
 Before propensity matching, 144 patients received AW and 91 patients underwent AR. Mean age was 64 ± 11.8 years. After propensity score matching and adjusting for significant differences in age, gender, body mass index, logistic EuroSCORE I, and left ventricular function, 69 patients in each group remained for further analysis. Rate of early reoperation due to tamponade, inhospital mortality, and survival rates did not differ. In both groups, the surgically treated aortic segment did not show enlargement, whereas the nontreated aortic arch showed comparable aneurysmatical progression.


CONCLUSIONS
 AW is safe and feasible and can be used in elderly or frail patients in order to avoid an AR. Progression of the remaining native aortic segments occurs, thus requiring strict life-long follow-up to ensure an elective and thus safe approach for appropriate consecutive surgical measures, if required.
