Retrograde visceral vessel revascularization followed by endovascular aneurysm exclusion as an alternative to open surgical repair of thoracoabdominal aortic aneurysm.

Staged visceral artery revascularization with occlusion of the proximal lumen enables endovascular exclusion of the entire thoracoabdominal aneurysm from a femoral approach. This technique has been successfully used in three patients at high risk for conventional repair.
