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.
