[Therapeutic embolization with polyvinyl alcohol (Ivalon). Clinical experiences].

Polyvinyl alcohol is rigid foam used in pressed or unpressed form for the purpose of embolisation. It is suitable for both micro-embolisation in the vascular periphery and for central vascular occlusion. Polyvinyl alcohol will result in permanent vascular occlusion. Basing on the experience collected with 71 embolizations, the article reports on the technique applied and on the results obtained with craniofacial, thoracic, abdominal, pelvic and peripheral embolisation.
