Schematic image of omental arteries and “arcades at the greater omentum” in case 2. The to-be-embolized left omental artery directly communicates with an omental artery branching from the right gastroepiploic artery. Note that proximal embolization at the origin of the left omental artery could cause incomplete hemostasis or rebleeding via collateral circulation from right omental arteries. Black arrow: right omental artery, white arrowhead: the tip of the 4.2 Fr guiding catheter positioned in the celiac artery, black arrowhead: right gastroepiploic artery, black curved arrow: left omental artery, star: the occluded point, red dot line: arcade omental branch between right omental artery and left one, a: stomach, b: spleen
