Arterial occlusion following embolization of an orbital arteriovenous malformation. A case report.

Orbital arteriovenous malformation is a rare condition which poses a management problem in view of the complexity of the vessels involved, and the potentially blinding and life-threatening complications from the modes of treatment. Treatment requires obliteration of the abnormal vascular communication. Vision may be adversely affected by the condition itself, as well as a result of invasive treatment modalities. This case reports such a situation where the visual outcome was severely affected following embolization of the feeding vessels.
