| [ Summary ] |
Acute small intestinal arterial hemorr hage is rare; however, it may precipitate hemorrhagic shock in a few cases of intractable bleeding. Bleeding may be associated with a multifactorial etiology; however, achieving satisfactory hemostasis is a priority in several cases. An important option to achieve hemostasis in cases of small intestinal bleeding is transcatheter arterial embolization based on interventional radiology (IVR) techniques. In recent years, the evolution of IVR devices has enabled ultraselective embolization that allows embolization of more peripheral arterial regions by short-segment embolization. This report describes the indications and limitations of IVR, embolization procedures, possible embolization-induced complications, and recent IVR techniques to treat acute small intestinal bleeding. |
