Utilizing patient-specific 3D printed guides for graft reconstruction in thoracoabdominal aortic repair

Abstract In thoracoabdominal aortic aneurysm repair, repairing the visceral and segmental arteries is challenging. Although there is a pre-hand-sewn and multi-branched graft based on the conventional image-based technique, it has shortcomings in precisely positioning and directing the visceral and s...
