Long-term effects of EVAR. Suprarenal versus infrarenal fixation.

Endovascular aortic aneurysm repair (EVAR) is the first line management of abdominal aortic aneurysms in many institutions. The relationship between EVAR and renal impairment, especially in the longer term remains unclear. Suprarenal graft fixation is widely used in order to achieve stable graft anchorage. Numerous studies have tried to answer the question about whether suprarenal fixation affects renal outcome. We reviewed the literature to investigate the relationship between endograft fixation and post-operative renal function.
