    Abstract:
    BACKGROUND: Arteriovenous malformations (AVM) of the head and neck are rare conditions with the majority of primary sites in the mid-face. Progression can lead to massive life-threatening bleeding. Treatment of choice is the combination of embolization and surgical resection. Diagnosis and management of AVM has been facilitated in recent years by the progress in imaging techniques and various microsurgical and endovascular embolization procedures. METHODS: This report presents the interdisciplinary approach to a case of life-threatening AVM of the mid-face in a 30-year-old patient. RESULTS: Angiography with embolization followed by resection and plastic reconstruction was performed. Follow-up showed incomplete obliteration of the AVM and lead to additional embolizations via the anastomosed radial artery. Complete eradication of the AVM was not possible during the three year follow-up period. CONCLUSION: In extensive vascular malformations of the head and neck, complete surgical removal is often impossible and associated with high risk of complications and mortality. Endovascular embolization is limited by the location of the AVM and can potentially cause stroke, ischaemia, necrosis, bleeding, blindness and adverse haemodynamic changes.
