3D printing is an evolving technology, still in its early developmental stages in
the treatment of thoracic and abdominal aortic aneurysms. Early experiences with 3D
printed aortic grafts are emerging.

- PreviewReconstruction of the visceral and segmental arteries is a challenging part of open surgical repair of extensive thoracoabdominal aortic aneurysm (TAAA). For more efficient reconstruction of these branching vessels, a technique of using pre-hand-sewn multi-branched aortic graft (octopod technique) has been adopted with the aid of 3D-printing-guidance in latest cases. The octopod graft has been employed for the extent II or III TAAA repair, in which the commercially available two 4-branched aortic grafts were interconnected before surgery.
