[Catheter embolization of inoperable kidney neoplasms with the GAW-spiral].

On the basis of 4 cases with inoperable hypernephroma the possibilities of the transfemoral catheter embolisation with the GAW-spiral are discussed. Simplicity of the technique and advantages in comparison to the material embolisation methods are discussed. The case in question was in 2 patients a primary embolisation, in 2 patients a secondary one with recanalised material embolisation. Up to now the patients were controlled over 3 months after the vascular occlusion. A recanalisation could not be observed, rather by total occlusion a tendency to the formation of collateral circulations.
