[Endovascular treatment for facial arteriovenous malformations using new particles: report of two cases].
Facial arteriovenous malformations (FAVM) are difficult to treat because of their highly vascular networks. Intravascular treatment using liquid material to occlude the FAVM occasionally results in skin necrosis after embolization. The use of particulate materials to obliterate the nidus often fails to obtain a permanent cure due to arterial recanalization. We report two patients with FAVM who were successfully treated with endovascular embolization using a new type of particulate material. One patient was treated with embolization only, the other was treated with embolization followed by surgical resection. Both patients showed clinical and angiographic improvement. Intravascular treatment using particles with a smooth surface and optimal size is safe and effective in the treatment of patients with FAVM.
