Endoleak after endovascular aneurysm repair: Current status

Since the introduction in 1991 of endovascular aortic aneurysm repair (EVAR), through its evolution from a straight graft system to modular component systems with supported prostheses, endoleak has been its Achilles heel. Defined as continued perfusion of the aneurysm sac in spite of endograft deployment and associated with sac expansion, re-intervention and the risk of rupture, here in this review we discuss the different types of endoleak and current evidence regarding its management.
