Endovascular stent grafting (EVAR) is now the preferred approach to repair of abdominal aortic aneurysms for many patients. One of the most common complications associated with EVAR is the development of an endoleak, or continued flow of blood into the aneurysm sac outside the graft. Type II endoleaks, those due to retrograde flow through a branch vessel such as the inferior mesenteric artery (IMA) or a lumbar artery, are the most common. Options for treatment include transarterial embolization, translumbar embolization, and laparoscopic ligation. Embolization techniques require reintervention in approximately 20%, with less than half free from aneurysm sac growth at five years, though current evidence is insufficient to determine a clear threshold for intervention or optimal technique.[1,2]
