[The value of embolization in severe epistaxis. Indications and methods (author's transl)].

When performed by a team who are experienced in the use of embolization of the external carotid region, this procedure is nowadays a safe and extremely effective method for treating severe, massive, uncontrolled, recurrent epistaxis. Arteriography shows the site of bleeding, the nature of the lesion, and the arteries affected. When carried out by the femoral or common carotid route, this method was effective in 52 cases of severe epistaxis of various origins: essential epistaxis, or from hypertension, trauma, Rendu Osler's disease, vascular malformations, carotidocavernous fistulae, benign or malignant tumors, hematological affections, or hemostatic disorders. To avoid risk it is essential that a perfect technique be used and a certain number of principles respected. The method is effective in cases were surgical hemostasis is insufficient, and its rapidity of action allows removal of packs immediately after embolization. This clearly underlines the value of constantly available vascular radiology units for treatment in this region as well as in other parts of the body.
