Abstract
Background: Large craniofacial high-flow malformations are rare, and there is no consensus on their treatment. Embo-lization has become an integral part of the treatment of these malformations. Cure of these lesions may be attained by embolization alone or embolization followed by surgical removal [5].
Objective: To evaluate the safety and efficacy of endo-vascular embolization and direct percutaneous injection in management of craniofacial arteriovenous malformation.
Patients and Methods: Thirteen patients with craniofacial AVMs with different sites. The patients underwent both endovascular embolization and percutaneous direct injection using liquid embolic materials.
Results: Post embolization angiogram displayed eight lesions were completely devascularized. The other lesions, three of them were subtotal devascularized (>_75%) after two sessions and the other two was 65% devascularized after one session. Minor complications were encountered (alopecia and ischemic necrosis at the site of injection).
Conclusion: Mixed endovascular and direct-puncture embolization is an effective and safe technique for preoperative devasularization of craniofacial AVMs.
