Abstract
Type II endoleak is the most common complication after endovascular abdominal aortic aneurysm repair. Type II endoleak with aneurysm sac growth is not benign for long-term outcomes of endovascular abdominal aortic aneurysm repair and should be treated to prevent secondary stent graft-related complications and aneurysm rupture. The current consensus is to consider treatments for persistent type II endoleak with significant aneurysm sac growth. For complete embolization of type II endoleak to obliterate the endoleak cavity with the elimination of all supplying arteries, it is necessary to select and combine the treatment options. Although the treatment techniques for type II endoleak have advanced, clinical outcomes remain unsatisfactory. To overcome this clinical discrepancy, the optimal patient-tailored treatment strategy is required in clinical practice, with an understanding of the current status and limitations of treatment for type II endoleak.
