Abstract
The arteriovenous malformation (AVM) is a vascular malformation characterized by fistulas between arteries and veins forming a nidus, without interposition of capillary vessels and of which early draining vein is identified at the digital angiography. Potential reports of its existence date from the second century AD. Spetzler and Martin (S-M) proposed a classification considering three features and Lawton then added new predictors. A maximum of 10 score can be achieved by applying the modified S-M grade system. This classification guides decision-making and the possible choice of the multimodal treatment (surgery, radiosurgery and embolization). We discuss historical, pathological, clinical and therapeutic characteristics of the condition. Much emphasis was placed on the AVM classified as grade III, once it requires multimodal therapy. Surgical technique and anatomical nuances are well described in the text and we also report cases to demonstrate our approach to the patients with AVM.
