Extent of Aortic Arch Repair in Acute Aortic Type A Dissection: How Far Should We Go?

Objectives: Total aortic arch replacement (TAR) with an elephant trunk represents the standard procedure for surgical treatment of acute type A aortic dissection (ATAAD) involving the distal aortic arch. Aim of the present study was to compare TAR to the hemiarch replacement (HAR) in terms of mortality, permanent neurological dysfunctions (PND) and aortic redo-surgery in a long-term follow-up.
