**1. Introduction**

Type A aortic dissection (TAAD) represents a double challenge: a short-term challenge with a 30-day mortality around 25% [1] and a long-term challenge with an excess of morbidity and mortality for this population [2]. Concerning the shortterm evolution, the intrahospital mortality is mainly influenced by patient history and preoperative complications [2]. Concerning the long-term evolution, the excess of morbidity and mortality seems correlated to two main complications: complications of hypertension such as strokes and ischemic heart disease and complications of aneurysmal evolution of the descending aorta such as aortic rupture and reoperations [3]. Thus, the main challenge of the surgical management of the TAAD is to strike a balance between keeping an early mortality rate as low as possible and preventing long-term morbidity.
