[Stanford Type A Acute Aortic Dissection after Coronary Artery Bypass Grafting using Automated Proximal Anastomotic Device].

Stanford type A acute aortic dissection after off-pump coronary artery bypass grafting( OPCAB) is a rare but potentially fatal complication. A 61-year-old man with subacute Stanford type B aortic dissection underwent a triple OPCAB using an automated proximal anastomotic device. On postoperative day 4, he had a sudden syncope. An enhanced computed tomography (CT) scan revealed Stanford type A acute aortic dissection. He underwent emergent total aortic arch replacement along with an open stent graft deployment. The entry of the dissection was located at the proximal anastomosis site of the vein graft. This case demonstrates that this device should be used carefully in patients with a history of Stanford type B aortic dissection.
