Preoperative CTA of the aortic blunt traumatic injury.

Figure 1
A, 3D reconstruction of the preoperative CT angiography showing the grade III aortic blunt injury at the level of the small curvature of the aortic arch (blue arrow). The anomalous left vertebral artery arising from the aortic arch is indicated by the yellow arrow. B, Multiplanar reconstruction of the postoperative angio-CT scan, showing good positioning of the fenestration of the physician-modified graft, with preserved patency to both the LSA and LVA. C, 3D reconstruction of the final angio-CT, after deployment of the aortic nitinol bare-metal stent. Note the “open fenestration,” including the origin of the LSA and LVA, with preserved patency of the aortic branches.

Figure 2
A, Axial cut of the CT angiography scan showing the preoperative planning of the open fenestration, to include the origin of both the LVA and LSA. B, Sizing of the surgeon-modified graft. To calculate the length of the “open fenestration,” 3 mm was added on each side to the distance between the proximal origin of the LSA and the distal end of the LVA. To calculate the width of the “open fenestration,” 1 mm was added on each side compared with the LSA diameter. C, Preparation of the surgeon-modified graft. After partial deployment, the “open fenestration” is outlined on the stent graft fabric using a ruler and sterile marking pen. The fenestration is reinforced with the loop of a snare, then the modified stent-graft is reloaded in the existing sheath using a temporary looped strand to collapse each stent.
