ABSTRACT

Gastrointestinal (GI) hemorrhage is characterized into upper and lower bleeding, divided anatomically by the ligament of Treitz. 85 percent of GI bleeding will resolve with supportive measures alone, whil interventions are reserved for those patients failing this treatment. In this first instance upper GI bleeding will go to the endoscopist with high rates of success in both finding the site of hemorrhage and treating. Upper GI bleeders will usually only come to interventional radiologist (IR) when endoscopy fails. Acute lower GI bleeding is more difficult because it is more intermittent, and the efficacy of endoscopy (especially in the unprepared bowel) is much less. Consequently, in most practices the first interventionalist involved in this cohort are the IRs. This presentation will detail which patients should undergo embolization, when and how.


La hemorragia gastrointestinal (HG) se divide en hemorragia alta y baja en base al ligamento de Treitz. Ochenta y cinco por ciento de la HG cesa espontáneamente; las intervenciones están reservadas para aquellos pacientes en que falla el manejo conservador. En primera instancia, la HG alta es de manejo endoscópico con una alta tasa de éxito en el diagnóstico y tratamiento. Los pacientes con HG alta deberán ser intervenidos por radiología intervencional (RI) cuando la endoscopia falla. La HG baja aguda es compleja debido a su intermitencia, y la eficacia de la endoscopia (especialmente en el intestino no preparado) es mucho menor. Consecuentemente, en la mayoría de los casos la RI estará involucrada como primer peldaño en este algoritmo. Esta presentación detalla qué pacientes requieren embolización, cuándo y cómo.
