Accessory Renal Arteries Role In Endovascular Treatment Of Abdominal Aorta Aneurysms

Objective: Accessory renal arteries (ARAs) often co-exist with abdominal aortic aneurysms (AAAs); in fact between 9.5% and 16.2% of patients undergoing endovascular aortic aneurysm repair (EVAR) present with an ARA emerging from the neck, the aneurysmal, sac or the iliac arteries. The current evidence supports the coverage of an ARA localised at the neck level to obtain an adequate sealing zone. On the other hand, EVAR is associated with renal dysfunction, and ARA exclusion could further aff5ct renal function, and the ESVS guidelines recommend the ARA preservation when the diameter is more than 3 mm or when it vascularises more than one-third of the renal parenchyma, although the level of evidence for this recommendation is weak.
