title: [Preoperative renal artery embolization of malignant tumors in external patients].
abstract: In 53 external patients with extensive malignant renal tumours before nephrectomy the renal artery was closed centrally by radioopaque ivalonchips. 46 arteries were completely obturated, in 7 cases the embolization was incomplete. This method of embolization is indicated preoperatively because there are some advantages concerning technique of operation. In or ivalon-material there was only one complication without clinical symptoms. The occurring ischemic pain was controllable by medicaments and eased off within some hours. Directly after transcatheter occlusion the patients can be transported back under first aid conditions in hospital where will be nephrectomy carried out.
