Type II endoleak is the most common type of complication following endovascular aneurysm repair. Retrograde flow through branch vessels as the inferior mesenteric artery continues to fill the aneurysm sac. It usually resolves spontaneously over time and requires no treatment unless the aneurysmal sac continues to expand in size.

In this case, there is leakage through the recanalized sacral artery, with extravasation into the inferior-posterior segment, featuring type 2 endoleak.

Due to the patient old age, it was only followed up.
