[Palliative disconnection of the kidney by transcatheter arterial embolization (author's transl)].

To eliminate urine production of one Kidney transcatheter embolization of the renal artery was performed in 11 patients with mallignant tumors in the area of the pelvis; in addition to the abave procedure in 9 patients a urinary; diversion by transrenal catheter and a ureteric ligation of the opposite side was also carried out. The therapy is of palliative character and signifies the smallest intervention possible to most treat effectively involuntary urination caused by urine fistulas, painful pollakisuria caused by shrinking bladders, and to treat painful hydronephrosis caused by tumors and the like.

[The catheterembolisation for permanent occlusion of the renal artery--anaesthesiologic views (author's transl)].

Experiences with a new radiological technique, namely embolisation of the renal artery with a spiral from Gianturco, are reported. Continuous epidural block has been found to be the best method of anaesthetic management. The technique of embolisation was used in 17 patients.

[Arteriography in old age--an assessment of the risks and technique (author's transl)].

Of 1,263 arteriograms performed over a period of two and a half years, there were 166 patients aged 70 years or more. The indications, angiographic findings and results have been examined retrospectively. In seven patients only was it impossible to carry out the examination because of advanced vascular disease in the pelvis.

[The Gianturco method of spiral embolisation of the renal artery (author's transl)].

Spiral embolisation of a renal artery by the Gianturco method was carried out in eight patients. Our early experience with this technique is described. In seven patients it was possible to occlude arterial flow to the kidney completely, or almost completely.

[Transcatheter embolization of renal artery--alternative to preoperative renal tumour radiotherapy? (author's transl)].

Transcatheter coil embolization (according to the method of Gianturco) was performed in 18 patients. It resulted in prompt and permanent occlusion of the renal artery without considerable effort and with acceptable risk. The favourable benefit of this procedure is technical facilitation of tumornephrectomy, cutting down the time of surgery, reducing intraoperative hemorrhage and danger of venous displacement of tumor-cells.

[Experimental studies on tumor vascularization (author's transl)].

The development of tumor vascularization of subcutaneously and intramuscularly implanted myelosarcoma I 58 of the rat was investigated. Various stages of tumor development were studied by arteriography, venography and microangiography. The roentgenographic signs known intravital angiography are related to the temporal sequence of the tumor development.

[Radiation therapy of an inoperable giant cell tumor (author's transl)].

The case of a patient showing an inoperable giant cell tumor in the right wing of the ilium, with extension to the sacrum, is reported. Following radiation therapy with 7000 rd from telecobalt a complete regression of the tumor could be represented angiographically.
