Endovascular treatment of trigeminal neuralgia caused by arteriovenous malformation: is surgery really necessary? - 10/03/08
A case is presented with secondary trigeminal neuralgia (TN) caused by an arteriovenous malformation (AVM) of the cerebellopontine cistern, which was detected by radiological work-up for planned microvascular decompression. An AVM surrounding the trigeminal nerve was demonstrated on thin-slice heavily T2-weighted 3D-sequence on magnetic resonance imaging (MRI) and confirmed by angiography. The first therapeutic step was endovascular embolization with complete obliteration of the AVM and cessation of pain. Nevertheless surgical excision was performed in order to remove compressive vessels and to prevent a recurrence of pain.
