Arteriovenous mal­for­ma­tions ­are ­rare vas­cu­lar ­lesions con­sist­ing of a cen­tral nid­us of anom­a­lous ­shunts ­between ­venous ­and arte­ri­al ­system, ­with a net­work of col­lat­er­al sur­round­ing ves­sels trib­u­tary of ­the ­main ­veins ­and ­local-region­al arter­ies. In ­the ­head ­and ­neck, ­they ­are nor­mal­ly loc­al­ised in ­the ­cheek, ­lip ­and ­tongue. The opti­mal treat­ment is rep­re­sent­ed by selec­tive embol­iza­tion asso­ciat­ed to sur­gi­cal exci­sion. The ­authors ­describe ­the ­case of a con­gen­i­tal ­high-­flow arter­i­ov­e­nous mal­for­ma­tion, ­with a ­nasal ­root loca­tion, sup­plied syn­chro­nous­ly by ­the branch­es of ­the oph­thal­mic, infra­or­bi­tal ­and ­facial ­artery.
