Abstract:
The extent of repair in patients with acute type A aortic dissection is often determined by factors such as entry tear location, aortic anatomy, malperfusion and team expertise. The hybrid arch frozen elephant trunk, which has become an established technique to extend the distal acute type A aortic dissection repair, is particularly useful in malperfusion; however, it remains technically challenging and is associated with increased duration of circulatory arrest and risks of spinal cord ischaemia. Proximal dissection flap extension often determines repairability versus replacement of the aortic root. We present a case report highlighting the proximal and distal extent of repair in a patient with a known ascending aortic aneurysm presenting with an acute type A aortic dissection, with malperfusion, undergoing a successful bio-Bentall procedure and hybrid arch frozen elephant trunk repair.
