Acute Type A Aortic Dissection: Managing More Than Just the Entry-Tear.

As emergency repair for acute type A aortic dissection is improving, the reintervention rate increases. Over 10% of cases require an aortic reintervention, which should ideally be performed in an early stage to allow for positive aortic remodeling and to prevent limitations by the stiffened aortic flap. These reinterventions remain a surgical challenge and may come with complications. We provide a comprehensive overview of different management strategies and their success in treating aortic adverse remodelling, based on current evidence of the literature. Two meta-analyses and an additional literature search yielded comparable mortality rates between limited repair and extensive repair. Cardiopulmonary bypass time, cross clamping time and cardiac arrest time were significantly shorter in limited repairs. Reintervention rate was generally lower in extensive repair, although not always significant. In conclusion, the early aggressive approach may be useful to lower reintervention rates. However, it has not yet been proven to be more beneficial. It will be imperative to develop a patient-specific early stage prediction model for residual aortic reintervention.
