Introduction: The treatment options for an infected fenestrated endovascular aneurysm repair (FEVAR) are limited. Report: A patient with a bi-renal FEVAR developed a type 1a and type 3 endoleak, with destruction of the neck of the aneurysm, likely due to infection. In a tapered thoracic aortic stent, "home-made" fenestrations were created for the renal arteries and superior mesenteric artery. Successful coverage of the infected aorta excluded the endoleaks. Life-long antibiotics were commenced. Discussion: There was a risk of imminent rupture, thus ruling out waiting for a custom-made FEVAR. This technique facilitated emergent treatment, and obviated the need for open surgery.
