Abstract:
Over the past three decades, transcatheter arterial embolization has become the first-line therapy for the management of acute nonvariceal upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the treatment of bleeding for a variety of indications. Transcatheter arterial embolization is a fast, safe, and effective minimally invasive alternative to surgery, when endoscopic treatment fails to control acute bleeding from the upper gastrointestinal tract. This article describes the role of arterial embolization in the management of acute nonvariceal upper gastrointestinal bleeding and summarizes the literature evidence on the outcomes of endovascular therapy in such a setting.
