Minimally invasive and effective endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is widely used and has become effective in this field. However, endoleak-related with enlargement of the aneurysmal sac in the long-term period is expected to increase in the future. We report herein a case of significantly increased aneurysmal sac of unknown cause 14 years after initial EVAR. After plication of the aneurysmal sac, CT showed abnormal heterogenous enhancement, and maximum shortest diameter was enlarged to 106 mm. The cause was speculated to be type IV or V endoleaks. We decided to apply a relining technique with a stent graft. Postoperatively, the aneurysmal sac was not enhanced and reduction in diameter was observed.
