Abstract
Head and neck arteriovenous malformations are rare, congenital, and high-flow vascular malformations characterized by abnormal communication between feeding arteries and draining veins without intervening capillaries. Arteriovenous malformations are considered the most dangerous type of vascular malformation because progressive symptoms and infiltration can result in potentially life-threatening consequences. Left untreated, arteriovenous malformations can cause significant cosmetic deformities, severe bleeding, and high-output cardiac failure associated with arteriovenous shunting. The effective treatment of arteriovenous malformations located in the head and neck region is quite challenging due to high rates of recurrence and potentially lethal complications. We describe a case presenting with large arteriovenous malformations in the face and neck. Despite attempting several treatments, including external carotid artery ligation and embolization with liquid embolic agents, the patient continued to experience recurrence and symptoms of bleeding and pain. After admission, reconstructive plastic surgery was performed, supplemented by percutaneous direct puncture embolization, using glue injected into the venous and transarterial embolization. The patient was discharged with clinical recovery. Digital subtraction angiography remains the gold standard for assessing symptomatic and aggressive arteriovenous malformations, both before and after treatment. The treatment of head and neck arteriovenous malformations often requires a multidisciplinary approach to achieve the best clinical results.
