Total Percutaneous Transfemoral Endovascular Treatment of Non-A Non-B Aortic Dissection

Abstract

Although open repair remains the mainstream treatment for aortic arch dissection, its surgical complexity and perioperative complications are significant. We developed a novel stentgraft system for less-invasive endovascular aortic arch repair. We successfully performed a total percutaneous transfemoral endovascular repair of aortic arch dissection using a novel off-the-shelf endograft system. This novel device allows endovascular aortic arch repair to be carried out through a transfemoral approach. Access is only needed from 3 percutaneous areas, bilateral femoral arteries and the right brachial artery. The key features of this system are a preshaped and steerable delivery system, outer and inner convertible innominate artery branch design, funnel-shaped inner branches, and a proximal tip capture mechanism.
