Transcatheter embolotherapy to treat lower gastrointestinal bleeding is very effective, with a relatively low rebleeding and ischemic complication rate, mostly occurring within the first month after the embolization. Long-term follow-up shows a very low late rebleeding rate, and half of the embolized patients survive more than 5 years. This study shows that the majority of patients presenting with lower gastrointestinal bleeding, unresponsive to endoscopic therapy, do not benefit from transcatheter embolization. In cases of angiography extravasation, a good immediate clinical outcome-defined as high immediate success with acceptable rebleeding-and ischemic complication rate may be obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
