Effective proximal sealing, especially in the long-term, remains a limitation of contemporary endovascular aortic aneurysm repair (EVAR). Endostaples that fixate the proximal stent-graft to the aortic neck wall, aiming for better apposition and proximal sealing have been recently introduced in clinical practice to address this problem. Initial experimental studies have shown that endostaples can increase proximal stent-graft fixation to levels equivalent or superior to that of a hand-sewn anastomosis. Further clinical studies aimed to investigate whether this increased proximal fixation results in reduced migration and better sealing with lower rates of type I endoleak. The present chapter discusses the efficacy of endostaples in reducing migration and type I endoleak after EVAR, based on published clinical data.
