[Indication for embolization (author's transl)].

Indications for transcatheter therapeutic embolization are presented in 24 patients who underwent this treatment within the past two years. The indication for this procedure regarding clinical success is discussed. Failure to control massive hemorrhage caused by tumor, trauma or a.v. shuntformation (congenital or acquired) are considered as main indications. It is emphasized that the surgical risk may possibly be reduced by preoperative embolization of well-vascularized lesions. Some of these lesions become operable by presurgical embolization.
