A 66-year-old-man who had undergone partial aortic arch and descending aortic graft replacement for a dissecting aortic aneurysm presented to our hospital with pain and beating swelling of his left back shoulder. Enhanced computed tomography and aortic angiography revealed graft rupture caused by one of the claws of a rib fixation strut. Furthermore, another claw had invaded a lung. We performed emergency thoracic endovascular aortic repair, and removed all of the struts 3 weeks later. Claw-type rib fixation struts have the potential to injure other organs, including prosthetic grafts. Careful follow-up is mandatory after implantation of this type of strut.
