The aim of this presentation is to learn how to assess the cerebral arteriovenous malformations using different image techniques and to describe the new advances of endovascular therapeutic options. To review theendovascular therapeutic approachof arteriovenous malformations, describing and comparing materials, techniques and resultsafters the treatment. Describe what to expect in the upcoming years about the management and therapeutic options ofthe arteriovenous malformations.

Cerebral arteriovenous malformations (AVMs) are complex lesions, with connections between arteries and veins without a capillary mediation due a dysregulation of angiogenesis. They have a variable clinical presentation, predominating in ages between 20-40 years on with no gender predilection. The therapeutic options are surgery, radiosurgery and recently described, endovascular embolization. Clinical presentation is often a neurological deficit due to hemorrhage, or symptoms related to occupation of intracranial space with seizures or headache. In recent years, endovascular treatment with embolization, is has been described; this isbecause...

General Features Vascular lesions of the brain are uncommon. Different classification systems have been put forward. The most commonly used classification system separates vascular lesions into arteriovenous malformations (AVMs), which may be either pial or dural, depending on the location of the shunt; cavernous hemangiomas (or cavernomas); capillary telangiectasia; and developmental venous anomalies. Brain AVMsare abnormal vascular connections that are presumably congenital in nature. It may also be a part of more extensive disease or syndrome. The transition between artery and vein can take place...

The treatment of AVMs is complex, and often there is no single therapeutic alternative. The new techniques of embolization offer an option for the management of AVMs, which although not risk free and are difficult procedures, are a faster option than the radiosurgery, reducing the risk of bleeding over time, and lower risk than the surgery. The AVMs are a complex entity, serious and difficult to manage and treat. This is why the percutaneous treatment with embolization is used more frequentlyusingnew materials and techniques. These...
