[Radiological embolization procedures in acute gastrointestinal, peritoneal and muscular hemorrhage]

Treatment of acute hemorrhage is particularly challenging due to its sudden onset and the fact that it is often life-threatening. Potential causes include bleeding ulcerations of the gastrointestinal tract or tumor bleeding, but acute bleeding can also occur spontaneously or be traumatic, iatrogenic, or inflammatory.

To demonstrate the basic principles of catheter embolization, as well as various embolic materials and their properties.

Today there are a wide range of embolization materials available. Ultimately the duration and extent of the desired occlusion are decisive when selecting an embolic material. Mechanical occlusion devices, particulates, and liquid embolic agents are available.

Irrespective of the wide range of different etiologies, radiological embolization therapy is a very safe treatment option in cases of computed tomographic evidence of active hemorrhage. Ultimately, the interventionalist's comprehensive knowledge of the relevant characteristics is crucial for the success of therapy.
