Key result
Open distal reoperation to replace the residually dissected thoraco-abdominal aorta after acute type A aortic dissection repair can be accomplished with acceptable morbidity and mortality.
Why the study?

Secondary open repair for chronic dissection after acute type A aortic dissection repair is feasible with acceptable morbidity and mortality in experienced centers.
Despite successful repair of acute type A aortic dissection (TAAD), the distal false lumen may remain patent resulting in progressive degeneration of the remaining distal aorta. This can lead to aneurysmal dilatation and risk of rupture. Open distal reoperation to replace the residually dissected thoraco-abdominal aorta may be accomplished with acceptable morbidity and mortality in experienced hands. This can be facilitated when the index operation for acute TAAD is tailored to exclude all primary tears and set the arch and descending aorta for a subsequent open, endovascular or hybrid procedure.

Assi et al. (2018) conducted a review in Chronic dissection after acute repair of type A aortic dissection. Secondary open repair was evaluated. Open distal reoperation to replace the residually dissected thoraco-abdominal aorta after acute type A aortic dissection repair can be accomplished with acceptable morbidity and mortality.
