OSSEOUS CRANIOFACIAL ARTERIOVENOUS-MALFORMATIONS IN THE PEDIATRIC POPULATION

Osseous craniofacial arteriovenous malformations are rare and challeng ing entities. A 20-year retrospective review at our institutions ident ified 47 cases of craniofacial arteriovenous malformations, 3 of which were in children with extensive osseous facial structure involvement. Diagnostic evaluation included computed tomography, magnetic resonanc e imaging, and angiography. A 3-stage treatment protocol employed both transarterial embolization and direct intralesional puncture emboliza tion followed by complete surgical resection. Mean intraperative blood loss was limited to 1000 mL. There were no complications during thera py. All 3 patients are without recurrence at 2- to 4-year follow-up. O sseous craniofacial arteriovenous malformations should be approached w ith multimodality therapy, incorporating interventional neuroradiologi c and surgical management. Using the outlined protocol, these lesions can be treated safely and effectively.
