[Chemoembolization of liver tumors (VX-2) using lyophilized Spherex].

Chemoembolisation is a new promising approach. Until now no standardized procedures exist for the production of the embolisate-cytostatics mixture. A main technical problem when doing chemoembolisation is the proof of the complete peripheral vascular occlusion. By using lyophilized Spherex and cytostatics, diluted in x-ray contrast media, frozen pictures can be obtained and the complete proof of the embolisation is possible. Therefore the conventional x-ray examination can be used to monitor the embolisation treatment instead of the much more sophisticated DSA technique.
