Transcatheter therapeutic arterial embolization.

Transcatheter therapeutic arterial embolization was employed in 11 patients with gastrointestinal hemorrhage and 8 patients with bleeding from other sites. Hemorrhage was stopped successfully in all of the patients with gastrointestinal bleeding and 6 of the 7 patients with active bleeding from other sites. There were no significant complications or sequelae, although ischemia msy cause problems in such patients. Embolization is of considerable value when pharmacological therapy fails or is not appropriate due to the site of bleeding. In some cases it may represent the definitive treatment, as in pelvic trauma or renal hemorrhage; in others, embolization may serve to halt bleeding long enough to permit surgery. Therapeutic embolization should be considered whenever active extravasation of contrast material is demonstrated.
