[Significance of the embolization of the arteria renalis for the treatment of kidney tumours (author's transl)].

In 24 patients with malignant kidney tumours percutaneous embolizations of the arteria renalis were performed in about 1 year. The material for embolization was gelatine-sponge-particles. The embolization was done pre-operatively, usually in connection with the arteriographic examination of kidney tumours (hypernephroid carcinoma). In 2 patients without operation it was done as a palliative measure. Our favourable results to improve the operability of tumours agree with reports in the literature. According to our opinion the pre-operative embolization of the arteria renalis with kidney tumours offers the possibility of a blood-sparing operation and a reduction of tumour-cell outwashings.
