Proximal endovascular blood flow shunt for thoracoabdominal aortic aneurism without total aortic clamping

The authors present a surgical approach to type III and IV Crawford aneurysms that does not need total aortic clamping, which allows the more objective prevention of direct ischemic damage, as well as its exclusion by the endoprosthesis implantation, shunting the flow to the synthetic graft.

作者提出了一种针对Ⅲ型和Ⅳ型克劳福德动脉瘤（Crawford aneurysms）的手术方案，该方案无需行全主动脉阻断，可更客观地避免直接缺血性损伤；同时可通过腔内支架植入术（endoprosthesis implantation）实现动脉瘤隔绝，并将血流分流至人工血管移植物（synthetic graft）。
