Abstract
BackgroundAcute aortic dissection (AAD) is a rare, but a life-threatening condition which can lead to coronary, brachiocephalic or branch vessel malperfusion, as well as aortic valve insufficiency, or aortic rupture. Mortality of surgical treatment in high-risk or elderly patients with Type A Acute aortic dissection (TAAAD) still remains high, and treatment for such patients remains controversial.Case presentationA new surgical approach which entails “stepwise external wrapping (SEW)” using a zero-porosity artificial graft was developed in extremely high-risk patients with TAAAD. Herein, we described its surgical details and showed two representative cases which was successfully done.ConclusionsOur SEW procedure is a feasible alternative to conventional graft replacement for TAAAD in extremely high-risk or aged patients, although the gold standard consists of surgical replacement of the dissected aorta.

Acute aortic dissection (AAD) is a rare, but a lifethreatening condition which can lead to coronary, brachiocephalic or branch vessel malperfusion, as well as aortic valve insufficiency, or aortic rupture [1]
The International Registry of Acute Aortic Dissection (IRAD) reported the overall surgical mortality for type A AAD (TAAAD) improved from 25 to 18% form advances made in surgical techniques, anesthesia, and perioperative medical management
We developed a new surgical approach which entails “stepwise external wrapping (SEW)” using a zero
Summary
Our SEW procedure is a feasible alternative to conventional graft replacement for TAAAD in extremely high-risk or aged patients, the gold standard consists of surgical replacement of the dissected aorta.
