Abstract
Type II endoleaks are the most common complication of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA). These endoleaks are the result of retrograde blood flow in arteries arising from the excluded portion of the aneurysm sac. The natural history of untreated type II endoleaks is not fully understood. This is confounded by the fact that imaging classification of type II endoleaks is not always accurate. However, it is clear that a subset of type II endoleaks are associated with aneurysm growth and rupture. Familiarity with the risk factors, prophylactic measures for prevention and imaging methods to identify type II endoleaks is essential for optimal management of this complication.
