Arteriovenous Malformation: Concepts on Physiopathology and Treatment

Arteriovenous malformations represent a complex type of vascular anomalies, caused by an abnormal angiogenesis. Genetic disorders are already catalogued for specific situations. These lesions can be classified according to its angio-architecture and clinical presentation. Patients with progressive symptoms according to Schobinger classification require treatment. Surgical treatment is indicated when total resection of the nidus is viable, which is not often. Embolization became the first-choice therapy, as it offers a way of treatment with low morbidity and acceptable results. Many devices are used to achieve nidus occlusion, but liquid embolic devices are the agents of choice. Total occlusion of the AVM is important to avoid stimulate more angiogenesis and lesion recurrence.
