Discussion

• Endoleak is a complication of endovascular aneurysm repair (EVAR)
• The endoleaks may continue to perfuse and pressurize the aneurysm sac, thereby conferring an ongoing risk of aneursym enlargement and/or rupture.
• Endoleaks are classified by the source of blood flow, and organized into five categories.

Endoleak classification scheme

• I: Attachment site leaks
• II: Collateral vessel leaks
• III: Graft failure (i.e. midgraft hole, junctional leak or disconnect)
• IV: Graft wall porosity
• V: Endotension (without or with endoleak)
