Endovascular repair of complex Juxtarenal aortic aneurysm using a combined fenestrated endograft and chimney technique.

Chimney EVAR (CHEVAR) and Fenestrated EVAR (FEVAR) are two options for management of very complex abdominal aortic aneurysm (AAA). While some anatomical factors may favor one strategy over the other, there are some cases where the anatomical challenges may require using a hybrid approach. We are reporting the case of an 84-year-old male with a 6.8×5.7cm infrarenal abdominal aortic aneurysm that arises immediately below the level of the renal arteries and extends down to just above the iliac bifurcation with occluded celiac and inferior mesenteric arteries and severe bilateral renal artery stenosis with caudally oriented right renal and cranially oriented left renal artery. This case shows that a combined strategy with fenestrated graft and Chimney stenting is feasible for aortic aneurysm repair and may offer a reasonable option for patients with very complex aortic anatomy.
