To be or not to be a neurovascular conflict: importance of the preoperative identification of the neurovascular conflict in the trigeminal neuralgia
نویسندگان
چکیده
The trigeminal neuralgia caused by neurovascular compression is a neurosurgical pathology requiring the preoperative identification as exact as possible of the neurovascular conflict. In this case, neuroimaging is very useful, as it allows not only the determination of the neurovascular conflict of the trigeminal nerve, but also the correct indication of an adequate surgical approach.

Glossopharyngeal neuralgia caused by a complex neurovascular conflict: Case report and review of the literature
BACKGROUND Glossopharyngeal neuralgia (GN) is a rare condition characterized by severe, paroxysmal episodes of pain mainly localized to the external ear canal, pharynx, and tongue, usually caused by a neurovascular conflict between postero-inferior cerebellar artery (PICA) and IX cranial nerve. Sometimes there is also a compression of X c.n. CASE DESCRIPTION We present a case of a 71-year-old...
متن کاملDecision-making in classic trigeminal neuralgia concurrent with a pontine cavernous malformation: Causal or coincidental association?
Trigeminal neuralgia is classically associated with neurovascular compression of the trigeminal nerve, at the root entry zone (REZ). However, patients are occasionally affected by intra-axial involvement of trigeminal sensory fibers caused by demyelinating diseases, strokes and, rarely, pontine cavernous malformations. We discuss the management strategies and decision-making process in a 55-yea...

OBJECTIVE The aim of this prospective study was to demonstrate the influence of some factors on the prognosis of microvascular decompression in 37 patients with trigeminal neuralgia. METHODS The results of microvascular decompression (MVD) in 37 patients with trigeminal neuralgia were evaluated at 6 months after surgery and were compared with clinical and operative findings. RESULTS The sex...
متن کاملVascular Decompression in Trigeminal Neuralgia
Trigeminal neuralgia (TN) is a sudden, severe, brief, stabbing and recurrent pain within one or more branches of the trigeminal nerve. Although multiple mechanism involving peripheral pathologies at root (compression or traction), dysfunctions of brain stem, basal ganglion and cortical pain modulatory mechanisms could have role, neurovascular conflict (NCV) is most accepted theory. Patients wit...
متن کاملPreoperative simulation for microvascular decompression in patients with idiopathic trigeminal neuralgia: visualization with three-dimensional magnetic resonance cisternogram and angiogram fusion imaging.
OBJECTIVE Precise assessment of the complex nerve-vessel relationship at the root entry zone of the trigeminal nerve is useful for planning microvascular decompression in patients with idiopathic trigeminal neuralgia. We have applied a fusion imaging technique of three-dimensional (3-D) magnetic resonance cisternography and co-registered 3-D magnetic resonance angiography (MRA) that allows virt...
