Abstract

Objective: The objective of this article is to describe the trigeminal neuralgia related to cerebral vascular malformation that is rarely reported and the experience referring to endovascular treatment. Patients and methods: A total of 10 patients who had cerebral vascular malformation (AVM and dAVF) in a single center presented with trigeminal neuralgia. Clinical and angiographic presentations as well as their clinical outcomes after embolization were reviewed. Results: Of the 10 cases, seven dAVFs and three AVMs were detected. In contrast to the dilated feeding arteries, an ectasia of the draining vein that is adjacent to the root entry zone of the trigeminal nerve such as the petrosal vein and lateral mesencephalic vein has the major role in causing the trigeminal neuralgia. All of these patients had relief of facial pain after endovascular embolization during follow-up (mean 57.3 months, range 5 to 100 months). There were no permanent neurological deficits. Conclusions: Endovascular embolization is an effective method in treating trigeminal neuralgia related to cerebral vascular malformation.
