Endovascular Embolization of High-Risk Arteriovenous Malformation

Intracranial arteriovenous malformations (AVMs) are relatively rare cerebral lesions 0.06 up to 1.1 % of the general population. These lesion are of great importance, because they can result in significant morbidity and mortality among young people. The ultimate aim in the treatment of AVMs must consist in preventing the risk of future bleeding. This is achieved by single-step or gradual elimination of the pathological vasculature from the normal brain circulation - mainly by application of intravascular embolization agents. After developing the non-adhesive liquid embolic agent Onyx, the implementation of radical embolizations with much lower risk became possible.
