[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 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. In one patient, faulty technique lead to an avoidable complication resulting in dislocation of the spiral into the femoral artery. The Gianturco method has advantages compared with other embolisation techniques, being simple, rapid, complete and permanent. In addition to its pre-operative and therapeutic use with renal tumours, the method can be used to abolish function in one or both kidneys.

[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. Most examinations could be performed as planned. In three patients there were minor complications without consequence. In one patient the external iliac artery was occluded following catheter angiography, but this was disobliterated during a subsequent operation which would have been carried out in case. The severity of vascular calcification as seen on plain films gives no indication regarding the difficulties during catheterisation. If aortography by catheter is impossible, we demonstrate the aorta retrogradely by a counter-current technique, using the Hettler instrument. The Hettler technique does not increase the risk and has certain advantages for the examination of older patients.

[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. As a preoperative measure it facilitates tumournephrectomy, saves blood and reduces the danger of dissemination of tumour-cells during operation.

[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. The same favourable results will not be achieved by preoperative short-time radiation. Preoperative long-term radiation delays the necessary tumor-nephrectomy. Arterial embolization is preferred because it offers the wanted benefits of sufficient radiotherapy avoiding its disadvantages.

[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. The most significant signs during the period of observation are increase of number, dilatation and winding of arteries and veins in the tumor area. These alterations are observed earlier and more pronounced at the veins. Following subcutaneous tumor implantation, in all developmental stages there is a concentric arrangement of the tumor vessels with a dense peripheral tumor vascularization around an avascular tumor center. Contrary to this, following intramuscular tumor implantation, diffuse penetration of the tumor with vessels is observed. A peripheral vascularization type occurs with necrosis which is combined by an avascular tumor center. Already in the medium stage of tumor development signs of arterio-venous shunts occur regularly. Central tumor necrosis leads to extravasation of contrast medium which is known as a late tumor sign. The vascular pattern of the myelosarcoma T 58 is not only determined by the temporal sequence but also by the location of the tumor.
