Prevention and Treatment of Complications in Endovascular Aneurysm Repair: Type II Endoleak

Abstract

Endovascular aneurysm repair (EVAR) has become the standard treatment for abdominal aortic aneurysms. Technology has advanced and devices have improved but unresolved issues remain. Endoleak is a unique complication in EVAR, of which type II endoleak (T2EL) is the most common. No treatment is required for T2EL that occurs at the time of implantation, but there are cases in which the aneurysmal sac expands later during follow up period. Treatment of aneurysmal sac enlargement due to T2EL is challenging. Therefore, recently, efforts have been made to preventively reduce T2EL. This article reviews the current trends in the treatment and prevention of T2EL.
