title: Migration of the Zenith Flex Device during Endovascular Aortic Repair of an Infrarenal Aortic Aneurysm with a Severely Angulated Neck.
abstract: A woman in her 80s with an infrarenal aortic aneurysm was scheduled for endovascular aortic repair (EVAR). The aneurysm had a severely angulated neck (SAN), and the Zenith Flex device was selected. Completion angiography showed migration of the main body resulting in right renal artery stenosis. A Palmaz genesis was placed across the renal orifice. The patient had no renal dysfunction and was discharged 7 days after EVAR. If Zenith Flex devices are used for a SAN, it is necessary to consider not only the position of the renal artery but also the appropriate position of the stent-graft.
