Techniques and results of therapeutic catheter embolization of congenital vascular defects.

Transcatheter embolization in congenital vascular malformations (CVM) is an alternative or additive method in the curative and palliative treatment of hyperdynamic arteriovenous malformations (AVM). Its indications and its mostly interdisciplinary treatment ought to be managed by teamwork. The safe and adequate transcatheter vasoocclusion depends furthermore on an optimal choice of applicating devices (catheters, guide wires etc.) and suitable embolic materials. Semi-fluid Ethibloc is in our eyes actually the most effective embolizing agent for getting a safe and permanent central occlusion of congenital av-fistulae.
