[Criteria for diagnostic and therapeutic methods of vascular embolization (kidneys, spleen, liver) (author's transl)].

Basing on the findings in patients with extensive carcinomas of the kidneys, the article reports on the various possibilities of application of occlusion spirals (Gianturco's method), of injectable occlusion materials and a combinations of both methods. In the authors' own experience, the spiral technique has mostly proved successful in achieving embolization of the arteries of the kidney 24 hours before surgery. Both the spiral technique as well as the use of injectable emblizates and a combination of both are used in the treatment of macrohaematurias in non-operable kidney tumours. The article reports on the technical conditions, indication and methodical limitations of embolization of the splenic artery, basing on three actual cases. The conditions and technique of embolization of branches of the hepatic artery are discussed by means of the findings obtained in two patients with liver metastases of an insulinoma.
