[Absolute alcohol, an adjustable embolization material in kidney tumors].

Fourty-four patients with angiographically verified malignant renal tumors underwent a complete or selective embolisation of the affected kidney with absolute alcohol. The occlusion is effected by slow infusion of absolute alcohol. The technique is supported by animal experiments. The quantity of alcohol applied is measured by its intracorporal spread. The method of slow infusion is compared to other published embolisation techniques using absolute alcohol. This method allows an individual application of the vascular occlusion of the tumor supplying and the normal tissue supplying vessels, depending on size and localisation of the tumor, and further clinical data.
