How long do Fenestrated & Branched Repair last?

Patients who undergo fenestration and branch repair should still undergo regular interval CT scans. Many of those patients will require secondary intervention to touch up on the main graft or the branch vessels that go to the aortic branches like the celiac or the superior mesenteric artery or the renal arteries. So regular follow-up CT scans is paramount in all these patients to maintain the graft function as well as the exclusion of the aneurysm.
