1. A method of treating an aortic aneurysm of a patient with an endovascular graft system and mitigating post implant syndrome inflammation resulting therefrom, comprising:
placing at least one prosthesis in an aortic aneurysmal space, said prosthesis comprising a stent-graft and a double-walled filling structure, wherein the filling structure comprises an outer wall, an inner wall, and a fillable space between the outer wall and the inner wall;
radially expanding the stent-graft with an expansion balloon at a first pressure of at least about 180 mm Hg;
filling the filling structure with a first filling agent such that the filling structure expands and contacts a thrombus disposed in the aneurysmal space;
removing the first filling agent from filling structure;
filling the filling structure with a second filling agent such that the filling structure expands and contacts the thrombus;
radially expanding the stent-graft with an expansion balloon at a second pressure thereby causing the filling structure with the second filling agent to place an effective amount of pressure on the thrombus;
wherein the effective amount of pressure placed on the thrombus mitigates the effects of post implant syndrome associated with the prosthesis by reducing inflammation in the aneurysm.
