ABSTRACT

N-butyl cyanoacrylate glue is well established as a transcatheter or direct injection embolic agent. Herein, targeted glue embolization was performed by direct needle injection into peripheral portal branches and along the surface of the liver to directly treat actively extravasating portal venous injury. In both cases, hemodynamically unstable patients underwent exploratory laparotomy, which was not able to definitively treat the hemorrhage. Subsequently, emergent visceral angiography and indirect portography revealed active portal phase extravasation. Transhepatic direct needle injection of the peripheral portal active extravasation with glue was successful in both cases and the patients stabilized, demonstrating this as an efficacious salvage approach.
