ABSTRACT
An arteriovernous malformation (AVM) occurring in the eyelid and orbit grows in size if left untreated and causes cosmetic problems, but the AVM represents a treatment challenge because of its high-flow characteristics and involvement of several arteries. We examined two patients with AVM of the eyelid and orbit, which was confirmed by angiography and computed tomography. Treatment of each patient started with neuroradiologic embolization of the vascular lesion. A single procedure embolization was effective in one patient, but three embolizaiton procedures were needed in the other patient to get a satisfactory result because the lesion showed complex vascular association. Surgical excision was then performed in each management was only transient dyspnea in one patient. In managing AVM occurring in the eyelid an orbit, preoperative adjuvant embolization and surgical management could make inoperable lesions operable.
