Endoleak: type Ic and ruptured abdominal aortic aneurysm


Endoleak: Persistent perfusion of excluded aneurysm sac after endograft placement.

  • Type I: perfusion of aneurysm sac via incomplete/ineffective seal at endograft attachment site.
    • Type IA: originates at proximal attachment site
      • e.g. infrarenal attachment of upper margin of bifurcated abdominal aortic endograft body
    • Type IB: originates at distal attachment site
      • e.g. common iliac artery attachment of limb of bifurcated abdominal aortic endograft

Type I endoleak should always be repaired when identified: If noted during EVAR or thoracic endovascular aortic repair (TEVAR), should be treated at that time. Should also treat any delayed type I endoleak seen on follow up imaging.
