A novel conformable embolic for selective transarterial embolization of acute hemorrhages: a technical note.

Background: Obsidio conformable embolic (OCE, Boston Scientific, MA) is a novel, radiopaque and conformable embolic. The purpose of this report is to describe its use for treatment of acute intra-abdominal hemorrhages.

Methods and results: Three patients presented with acute hemorrhage and were treated with OCE, including post-paracentesis hemorrhage, penetrating trauma to the liver, and blunt trauma in the spleen. All cases were performed under moderate sedation, with hemostasis achieved by end of procedure using less than 1 vial of OCE (0.2-0.4 ml). No severe adverse events occurred. None required repeated treatment.

Short conclusion: OCE is a safe and effective embolic agent for treatment of intra-abdominal or visceral hemorrhage. Future studies with larger sample sizes and longer follow-up are warranted.
