A modified root reinforcement technique for acute aortic dissection with a weakened aortic root: a modified Florida...

Despite marvelous advances in repair for acute type A aortic dissection over past decades, it remains challenging to repair the aortic root when aortic dissection extended to the sinuses causes the fragile root because of its thinner layers, which are susceptible to suture trauma. Here, we describe a modified Florida sleeve technique to strengthen the weakened aortic root. After mobilization of the aortic root and the coronary arteries, a designed Dacron tube graft was wrapped outside the sinuses as neo-adventitia to reinforce the dissected weakened wall. During surgery for aortic dissection, our technique is easy and effective to reinforce a weakened root and avoid bleeding. Furthermore, this might be an alternative technique to restore and maintain the geometry of the aortic root.
