(A) An Injection to the abdominal aorta shows a microaneurysm of the left hepatic artery (white arrow) and intraparenchymal segment aneurysm of the right renal artery (black arrow). (B) Selective injection with a microcatheter shows contrast agent extravasation distal to the left gastric artery (white arrow). (C) An injection to the left gastric artery after embolization shows an active bleeding vessel occluded without contrast agent extravasation (white arrow).

One microaneurysm was seen in the left hepatic artery and another one in the intraparenchymal segments of the right renal artery (Figure 1A). A 2.7-F microcatheter was used in a coaxial fashion to select a vessel with contrast agent extravasation (Figure 1B). Postembolization angiography demonstrated total occlusion of the active bleeding vessel (Figure 1C).
