Type I Endoleak Five Year after Endovascular Repair of Abdominal Aortic Aneurysm / 대한혈관외과학회지

ABSTRACT

Endovascular aneurysm repair (EVAR) surgery has become a more prevalent in recent years, as it is less invasive and requires a shorter hospital stay and recovery time, in addition to resulting in lower mortality. However, EVAR has the disadvantage of increased numbers of reintervention incidents, need of regular follow up, and uncertainty of long-term stability. Type II endoleak is the most common endoleak, but it mostly seals without intervention. Type I endoleak is a sealing failure around the graft and proximal neck or distal landing zone and usually occurs during the initial procedure, which can be corrected by ballooning, an additional stent (bare or graft), or surgery. Late type I endoleak can develop by migration of the graft or shrinkage or progression of aneurysm. Here we report a case of distal type I endoleak found 5 years after EVAR which was corrected by additional endovascular grafts.
