title: Double renal chimney graft using only femoral approach.
abstract: Endovascular aneurysm repair (EVAR) is a minimally invasive treatment that can be offered to most patients with an aortic aneurysm. Patients who are rejected from standard EVAR often have more extensive aortic pathology and more medical comorbidities. The advent of fenestrated and branched stent grafts gives us an opportunity to treat the most demanding aortic aneurysms endovascularly. Fenestrated stent-grafts, however, are costly and time-consuming to manufacture, which limits their applicability, especially in the emergency setting. The chimney graft is a stent placed parallel to the aortic stent-graft to preserve flow to a vital aortic branch that was overstented to obtain an adequate seal. The technique can be used as a planned operation but also as a rescue procedure to salvage a side branch unintentionally covered during EVAR. As visceral branches of the aorta are usually directed caudally these vessels are, therefore, preferably catheterized from a brachial approach. We describe a case of a successful positioning of the chimney graft using only the femoral approach. The only femoral approach to position a renal chimney graft isn't recommended for the routine procedure but it is proved to be useful in selected case and when other treatment options are excluded.
