Objective.  Trigeminal neuralgia is rarely caused by arteriovenous malformations of the posterior fossa. Embolization of aberrant vessels can provide symptomatic relief; however, embolization is not always technically possible, and its effects can be temporary. Embolization of the nerve's blood supply could reduce its excitability and provide pain relief. Setting.  The ...
