The chimney graft (CG) technique can be a useful alternative in treating aortic aneurysms with challenging anatomy, regarding the proximal sealing zone. We describe the case of a patient who developed a type Ia endoleak after chimney endovascular aneurysm repair for a juxtarenal AAA and underwent a proximal CG reconfiguration and implantation of an aortic cuff. The crossing configuration of the CGs should be avoided as it may compromise the circumferential apposition of the endograft and impede the thrombosis of the perigraft gutters. A proximal reconfiguration of the CGs, in case of type Ia endoleak is a useful option. The long-term efficacy of this option should be evaluated by meticulous follow-up.
