Endovascular treatment of persistent type II endoleak may not resolve the complication. We report two cases of sacotomy performed to treat this problem: the first case was in an emergency setting for aneurismal sac rupture, and the second occurred in an elective surgery setting after several unsuccessful endovascular procedures. In both cases, sacotomy allowed us identify the bleeding sources without aortic cross-clamping and endograft explantation. By minimizing hemodynamic modifications and reducing operative time, this procedure can be carried out even in patients considered unfit for surgery. Sacotomy could be considered as an alternative in selected cases of persistent type II endoleak with aneurysm sac enlargement.
