Initial experience using N-butyl cyanoacrylate for embolization of lower gastrointestinal hemorrhage.

Purpose: To report initial experience using N-butyl cyanoacrylate (n-BCA) to control lower gastrointestinal hemorrhage (LGIH).

Materials And Methods: From May 2005 to March 2009, 14 patients with LGIH underwent mesenteric angiography and transcatheter arterial embolization using n-BCA. Candidacy was primarily based on the patient's hemodynamic stability and the risk for future LGIH, determined by the presence of at least one of the following risk factors: more than one arterial feeder supplying the bleeding vessel, underlying coagulopathy, or need to resume anticoagulation after embolization.
