Review the brain arteriovenous malformations (AVMs) types. Review the classification of classic brain AVMs,
pyalarteriovenous fistulae and others. Learn about the treatment options and benefits from endovascular treatment.
Arteriovenous malformations (AVM) are shunt-like lesions between high flow nutrition arteries and drainage veins with a nest of anomalous vessels,
whose pathogenesis is not well understood (1) .They are generally believed to be developmental lesions or to be acquired.
Many theories have been suggested.
the retention of the primordial arteriovenous connections from fetal intracranial vasculature or failure of development of an intervening capillary network.

Findings and procedure details
Classic AVM The classic form of arteriovenous malformation involving the brain parenchyma,
it is characterized by a nidus in the transition between the feeding artery and draining vein.Its morbi-mortality is closely related to hemorrhages secondary to the rupture of an anomalous vessel or a high-flow aneurysm near or within the malformation (5,6) . Most AVMs are supratentorial,
with a description in the literature of close to 90%,
up to 9% multiple (6) . Location Supratentorial: 85-90%. 1/3...
The knowledge of different AVMs by Digital Subtraction Angiography allows classifying them properly and suggesting or performing an endovascular treatment with favorable potential results.
