Treatment options for late type III endoleaks after endovascular aneurysm repair.

Late type III endoleaks result from complete or partial separation of endograft device components. Component separation repressurizes the aortic sac and may result in aortic rupture. We report 4 cases of late type III endoleaks after initial successful endovascular aneurysm repair for abdominal aortic aneurysm. Our cases include 3 aortic cuff separations and 1 iliac limb separation. The average time before graft separation was 3.25 years with an average aneurysm size at re-presentation of 8.2 cm. Management of these complex cases will be discussed, the literature reviewed, and recommendations for treatment offered.
