[Late results following palliative vascular embolization in inoperable kidney tumors. (Preliminary report)].
During 18 months in 15 patients with inoperable renal tumours palliative therapeutic vascular embolisations were carried out with the help of an own catheter technique. In contrast to preoperative embolisation (16 patients) in the inoperable cases a non-absorpable polyvinyl alcohol foam substance ("Ivalon") was used, which leads to a secure permanent vascular occlusion. The haematuria occurring in all patients which many times threateningly increased was removed in all cases. There did not appear any essential complications. However, on account of the formation of a symptomatology of renal infarction a clinical after-treatment is necessary. In 12 patients regulary clinical and paraclinical control examinations during an observation period of on an average 11 months were carried out (minimum 6 months, maximum 18 months). 11 of these patients were still alive at the end of the report and had a tolerable or even improved general condition. In angiographical after-controls of 4 patients, and in one case by autopsy, permanent vascular occlusions with formation of necroses of a large area and partly considerable restriction of the tumour kidneys were found. In these cases the therapeutic embolisation led to a provable damage of the tumorous process. An influence of metastases distant from the primary tumour was not observed.
