Abstract
Purpose: We report a case of posterior ischemic optic neuropathy which occurred after transarterial coil embolization for cavernous sinus dural arteriovenous fistula (CSdAVF).
Case: A 74-year-old female was diagnosed with left CSdAVF, as a result of a detailed examination for left orbital pain and diplopia, and transarterial coil embolization was undertaken. After surgery, left orbital pain was reduced, although left upper quadrantanopia was detected. On her 13th post-operative day, the visual acuity of the left eye was lost, and unilateral blindness was diagnosed. Her intraocular pressure was not high, and her funduscopic examination findings were normal. In an orbital diffusion-weighted MR image, a high-intensity lesion localized in the left optic nerve was identified, and ischemic optic neuropathy was diagnosed.
Conclusion: We experienced a case of serious cranial nerve defect due to transarterial coil embolization.
