Background: Trigeminal neuralgia is a debilitating chronic condition characterized by severe recurrent hemifacial pain which is often caused by compression of the trigeminal nerve by an adjacent vessel loop. Microvascular decompression (MVD) surgery is an effective procedure that can lead to full symptomatic relief. Intracranial arteriovenous malformations (AVMs) are primarily congenital abnormalities that may be asymptomatic or manifest as seizures or focal neurologic deficits. They may cause intracranial bleeding and hence are promptly treated, often by endovascular embolization. This procedure is safe but may have a multitude of unpredictable complications. Case Description: A 33-year-old female presented with medically refractory trigeminal neuralgia secondary to Onyx embolization of a right occipital AVM 3 years prior. She underwent surgical exploration and MVD of the trigeminal nerve root which was found to be compressed by the previously embolized superior cerebellar artery. The procedure was successful and full symptomatic resolution was immediately achieved. Conclusion: Postprocedural trigeminal neuralgia is a procedural complication of Onyx endovascular embolization. It may be treated by MVD surgery regardless of the presence or absence of a compressive vascular loop on imaging.

Abstract This is the case of an 86-yr-old gentleman who presented with left facial pain exacerbated by eating, drinking, chewing, and shaving (distribution: V2, V3). The patient was diagnosed with trigeminal neuralgia and was refractory to medications. Imaging showed a superior cerebellar artery (SCA) loop adjacent to the trigeminal nerve root entry zone and a decision to perform a microvascular decompression of the fifth nerve was presented to the patient. After patient informed consent was obtained, a standard 3 cm × 3 cm retrosigmoid craniotomy was performed with the patient in a supine head turned position and in reverse Trendelenburg. The arachnoid bands tethering the SCA to the trigeminal nerve were sharply divided. A slit was then made in the tentorium and a 3 mm fenestrated clip was then used to secure the transposed SCA away from the trigeminal nerve. The SCA proximal to this was slightly patulous in its course so a small amount of a fibrin glue was also used to secure the more proximal SCA to the tentorium. The patient was symptom-free postoperatively and no longer required medical therapy. Additionally, imaging was consistent with adequate separation of the nerve from adjacent vessels.1-5

Anatomical Information

ABSTRACT The increasing use of microsurgical decompression for trigeminal neuralgia has created a need for more detailed anatomical information about the approach. To define better this anatomy, 10 cerebellar specimens obtained at autopsy were examined, and intraoperative findings in 30 patients with trigeminal neuralgia were analyzed. Since the infratentorial subdural space on the tentorial cerebellar surface is exposed to explore the trigeminal nerve in the infratentorial lateral supracerebellar approach, attention was directed to the following: the anterolateral margin of the cerebellar hemisphere, bridging veins on the tentorial surface, superior petrosal veins, and relationships between blood vessels and the trigeminal nerve. The lateral mesencephalic segment of the superior cerebellar artery at or near the bifurcation often compressed the nerve laterally at more than one point. With this approach, the relationship of the superior cerebellar artery to the nerve could be observed from the medial side of the tentorial surface. The infratentorial lateral supracerebellar approach is discussed and compared to Dandy's cerebellar route.

Abstract Background: Microvascular decompression is an accepted, safe, and useful surgical technique for the treatment of trigeminal neuralgia. Autologous muscle or implant materials such as shredded Teflon are used to separate the vessel from the nerve but may occasionally be inadequate, become displaced or create adhesions and recurrent pain. Objective: The authors evaluated the use of arachnoid membrane of the cerebellopontine angle to maintain the transposition of vessels from the trigeminal nerve. Methods: The authors conducted a retrospective review of microvascular decompression operations in which the offending vessel was transposed and then retained by the arachnoid membrane of the cerebellopontine cistern, specifically by the lateral pontomesenchepalic membrane. Results: This technique was used in 30 patients of the most recently operated series. Postoperatively, complete pain relief was achieved in 90% of the patients without any observed surgical complications. Conclusion: To the authors’ knowledge this is the first report in which the arachnoid membrane is used in the microvascular decompression of the trigeminal nerve. While this technique can be used only for selected cases, the majority of the vascular compressions on the trigeminal nerve are due to the SCA, so this sling transposition technique can be useful and effective.

The Relationship

✓ Compression and distortion of the trigeminal nerve by a tortuous and elongated superior cerebellar artery (SCA) is postulated to be a frequent cause of trigeminal neuralgia. This theory and the use of operative therapy in which the offending arterial loop is separated from the trigeminal nerve has created a need for more detailed information on the relationship of the SCA and the trigeminal nerve. In order to meet this need, 50 trigeminal nerves and the adjacent SCA were examined in 25 adult cadavers. Twenty-six of the 50 nerves examined had a point of contact with the SCA, but it was uncommon for the arterial contact to produce distortion of the nerve. In six instances, the contact was at the pontine entry zone of the trigeminal nerve, the site of arterial compression postulated to be associated with trigeminal neuralgia. Four trigeminal nerves (8%) had a point of contact with the anterior inferior cerebellar artery (AICA). The fact that large arteries are commonly in contact with the trigeminal nerve is important not only because of the controversial relationship of neurovascular contact to trigeminal neuralgia, but because of the possibility that major vessels may be encountered and injured during rhizotomy and other posterior fossa operations on the trigeminal nerve.

Abstract OBJECTIVE AND IMPORTANCE: Intrinsic arteriovenous malformation (AVM) of the trigeminal nerve is extremely uncommon and may be associated with trigeminal neuralgia. CLINICAL PRESENTATION: A 55-year-old man experienced severe lightning pain in the second and third divisions of the left trigeminal nerve territory. Vertebral angiography demonstrated an AVM fed by the superior cerebellar artery. Magnetic resonance imaging with three-dimensional spoiled gradient recalled acquisition at steady state revealed an AVM intrinsic to the left trigeminal nerve and a small arterial loop causing compression at the root entry zone of the trigeminal nerve. INTERVENTION: Intraoperative inspection revealed an indentation of the root entry zone caused by a small arterial loop but not by the AVM. The offending artery was displaced to decompress the root entry zone using a prosthesis without resection of the AVM. The patient was relieved of the neuralgia immediately after surgery without further neurological deficit. He has been free of trigeminal neuralgia during a follow-up period of 2 years and is scheduled to undergo stereotactic radiosurgery for the treatment of the AVM. CONCLUSION: Intrinsic AVM of the trigeminal nerve may cause trigeminal neuralgia. However, as in the present case, a coexistent vascular lesion rather than the intrinsic AVM could be a cause of the neuralgia.

Abstract The trigeminocerebellar artery (TCA) is an infrequent anatomic anomaly of the branches originating from the basilar artery. It is clinically identifiable by the presence of the ipsilateral superior cerebellar artery and the anterior inferior cerebellar artery, and its course from the basilar artery to the cerebellar hemisphere. Because of its anatomic proximity to the trigeminal nerve root, the TCA often causes trigeminal neuralgia (TGN). Unlike other common arteries, repositioning the TCA is not always feasible when it penetrates the trigeminal nerve root (the intraneural type of TCA). In addition, the rich perforators originating from the TCA may limit its movability. The nerve decompression technique in such a rare condition has not yet been fully assessed. In this video, we present the nerve-splitting method for the intraneural type of TCA, in which sufficient isolation of the sensory root is achieved. The motor root of the trigeminal nerve originates from the brainstem slightly rostral of the root entry zone of the sensory root. Dissecting the motor root from its exit to the porous trigeminus allows mobilization of the root together with penetrating TCA away from the sensory root. The movability of the TCA increases by dissecting its perforators to the nerve root and brain stem. Sufficient separation of the sensory root contributes to ensuring the surgical result of nerve decompression and reducing the risk of recurrence due to adhesion. No complications of motor root retraction, such as masseter weakness and malocclusion, were noted in our experience.  All data identifying the patients were anonymized. All procedures performed in this study were in accordance with the ethical standards of our institutional and national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards. This study also obtained approval from the ethics committee of our institution. Written informed consent was obtained from all individual participants, as well as their first-degree relatives, included in this study.

Trigeminal neuralgia is a chronic pain disorder affecting the face. In approximately 80% of cases, it is most commonly caused, when the root entry zone (REZ) of the trigeminal nerve is compressed by the superior cerebellar artery (SCA). The etiology of the remaining 20% of cases is distributed among venous, arteriovenous malformations, posterior fossa tumors, multiple sclerosis plaque compressions, and other pathologies. Combinations of those compressive factors are very rare.1 2 3 4 Herein, we present a video clip of microvascular decompression (MVD) in a 73-year-old female, who has failed conservative treatment with 6 medications over 10 years. She was affected by a unique triple compression of the right REZ by the SCA, anterior inferior cerebellar artery (AICA), and petrosal vein complex (Fig. 1A). Right-sided microsurgical decompression of the REZ of the trigeminal nerve through standard retrosigmoid craniotomy was performed by the senior author (K.I.A.). The SCA and AICA were separated from the nerve using Teflon pledgets. The petrosal vein complex was coagulated and divided, freeing up the right trigeminal nerve (Fig. 1B). The patient was discharged home on the third postoperative day with complete resolution of trigeminal neuralgia.The link to the Video can be found at: https://youtu.be/PYVvImGW0yE.

IntroductionThe LVIS Blue is an FDA-approved stent with 28% metallic coverage that is indicated for use in conjunction with coil embolization for the treatment of intracranial aneurysms. Given a porosity similar to approved flow diverters and higher than currently available intracranial stents, we sought to evaluate the effectiveness of this device for the treatment of intracranial aneurysms.MethodsWe performed an observational single-center study to evaluate initial occlusion and occlusion at 6-month follow-up for patients treated with the LVIS Blue in conjunction with coil embolization at our institution using the modified Raymond–Roy classification (mRRC), where mRRC 1 indicates complete embolization, mRRC 2 persistent opacification of the aneurysm neck, mRRC 3a filling of the aneurysm dome within coil interstices, and mRRC 3b filling of the aneurysm dome.ResultsSixteen aneurysms were treated with the LVIS Blue device in conjunction with coil embolization with 6-month angiographic follow-up. Aneurysms were treated throughout the intracranial circulation: five proximal internal carotid artery (ICA) (ophthalmic or communicating segments), two superior cerebellar artery, two ICA terminus, two anterior communicating artery, two distal middle cerebral artery, one posterior inferior cerebellar artery, and two basilar tip aneurysms. Post-procedurally, there was one mRRC 1 closure, five mRRC 2 closures, and 10 mRRC 3a or 3b occlusion. At follow-up, all the mRRC 1 and mRRC 3a closures, 85% of the mRRC 3b closures and 75% of the mRRC 2 closures were stable or improved to an mRRC 1 or 2 at follow-up.ConclusionsThe LVIS Blue represents a safe option as a coil adjunct for endovascular embolization within both the proximal and distal anterior and posterior circulation.
