Aneurysmal sac of the infrarenal abdominal aorta, which measures 61 x 60 mm. Extravasation of contrast medium (endoleak) at the back of the aneurysmal sac, especially through the sacral artery.
Type II endoleak are the most common type of complication following endovascular aneurysm repair. Retrograde flow through branch vessels as inferior mesenteric artery continue to fill the aneurysm sac. It usually resolves spontaneously over time and requires no treatment unless aneurysmal sac continues to expand in size.
On 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.
