To describe rapid prototyping or 3-dimensional (3D) printing of aneurysms with complex neck anatomy to facilitate endovascular aneurysm repair (EVAR). ⋯ Rapid prototyping of aortic aneurysms is feasible and can aid decision making and device delivery. Further work is required to test the value of 3D replicas in planning procedures and their impact on procedure time, radiation dose, and procedure cost.

To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3. ⋯ The periscope endograft is a simple technique to maintain perfusion to the LSA in cases where the aortic stent-graft crosses its ostium. The PG technique can be performed transfemorally and even percutaneously, and it can be applied to all supra-aortic branches. Early and midterm results are encouraging, but more experience and long-term results are mandatory before this technique can be widely recommended.
