The establishment of hepatic injured and hemorrhagic models of beagles and the interventional embolization using TACMs mixed thrombus. (a) The angiography of the normal hepatic artery; (b) the hemorrhage model made by a Swartz sheath (blue arrow); (c) the continuous leakage of contrast agent from injured right hepatic artery 5 minutes after hemorrhage model was established (red arrow); (d) the delivery of TACMs mixed thrombus (white arrow) by guiding catheter; (e) bleeding stopped completely after embolization; (f) angiography 1 week later after embolization; (g) angiography 4 weeks later after embolization; (h) angiography 12 weeks later after embolization.
