A multicenter survey on access to care in Multiple Sclerosis-related trigeminal neuralgia
2021
The prevalence of trigeminal neuralgia (TN) in patients with Multiple Sclerosis (MS) is higher than in the general population and its management can be particularly challenging due to a number of reasons including high recurrence rates, lack of MS-specific treatment guidelines and uncertainties about pain pathophysiology. Aim of this cross-sectional, multicentre survey was to gather information on the current treatment modalities and options of MS-related TN across 23 Italian MS centres. Initial medical management (carbamazepine or oxcarbazepine) of MS-related TN was fairly homogeneous throughout Italian centres. The most commonly available surgical procedure was microvascular decompression…
Characteristics and treatment of Multiple Sclerosis-related trigeminal neuralgia: An Italian multi-centre study
2019
Abstract Background The prevalence of trigeminal neuralgia (TN) in Multiple Sclerosis (MS) patients is higher than in the general population and its management can be particularly challenging. Our aim is to describe the characteristics, treatment and prognostic factors of MS-related TN in a retrospective multicentre study. Methods Neurologists members of the RIREMS group (Rising Researchers in MS) enrolled MS patients with a TN diagnosis and filled out a spreadsheet comprising their clinical data. Results Population consisted of 298 patients. First-choice preventive treatments were carbamazepine and oxcarbazepine. A surgical procedure was performed in 81 (30%) patients, most commonly gamma …
Presurgical evaluation of hemifacial spasm and spasmodic torticollis caused by a neurovascular conflict from AICA with 3T MRI integrated by 3D drive …
2014
Background: Hemifacial spasm (HS) and spasmodic torticollis (ST) are well-known disorders that are caused by a neurovascular conflict. HS is characterized by irregular, involuntary muscle contractions on one side of the face due to spasms of orbicularis oris and orbicularis oculi muscles, and is usually caused by vascular compression of the VII cranial nerve. ST is an extremely painful chronic movement disorder causing the neck to involuntary turn to the side, upward and/or downward. HS is usually idiopathic but it is rarely caused by a neurovascular conflict with the XI cranial nerve. Case Description: We present a case of a 36-year-old woman with a 2-year history of left hemifacial spasm …
Dolichoectasia of the vertebrobasilar complex causing neural compression
2014
Dear Editor, We have read with great interest the paper of Yuh et al.[4] reporting a case of symptomatic hydrocephalus due to vertebrobasilar dolichoectasia (VBD) compressing the brainstem. Ectatic or pathologically enlarged vertebrobasilar arteries have been reported with increasing frequency and associated with several clinical syndromes. These include an assortment of cranial nerve syndromes, transient or permanent motor deficit, cerebellar dysfunction, central sleep apnea, ischemic stroke, hypertension, and hydrocephalus as reported in the paper by Yuh et al.[4] Others and we have also described pyramidal tract signs and cranial nerve nucleus dysfunction caused by vascular compression o…
Cisternostomy for Traumatic Brain Injury: Pathophysiologic Mechanisms and Surgical Technical Notes
2016
Objective Traumatic brain injury (TBI) is one of the major challenges in health care, representing the third most frequent cause of death. Current optimal management is based on a progressive, target-driven approach combining both medical and surgical treatment strategies. Here we describe cisternostomy, an emerging surgical treatment for the treatment of TBI. Methods Cisternostomy is a novel technique that incorporates knowledge of skull base and microvascular surgery. By opening the brain cisterns to atmospheric pressure, the technique could decrease the intracranial pressure due to a backshift of the cerebrospinal fluid (CSF) from the swollen brain to the cisterns through the Virchow-Rob…
Sensitivity and specificity of MRA in the diagnosis of neurovascular compression in patients with trigeminal neuralgia
1998
The published rates of operatively confirmed neurovascular compression as the cause for trigeminal neuralgia range from 10 % to nearly 100 %. High-definition magnetic resonance angiography (MRA) was performed in 27 consecutive patients (in 6 cases with 3D reconstructions) to show neurovascular compression preoperatively. The MRA findings were compared with the relationship between the Vth nerve and the surrounding vessels at surgery. In 23 patients MRA showed present neurovascular compression in accordance with surgical findings (18/27 in complete accordance of type and side of vessel, site and direction of compression). One woman had no neurovascular compression either on MRA or intraopera…
Unusual recurrence of trigeminal neuralgia after microvascular decompression by muscle interposal.
2011
Summary Background Patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression (MVD) typically undergo less invasive procedures in the hope of providing pain relief. However, re-operation should be considered in selected patients. Case Report A 48-year-old woman presented with recurrent trigeminal neuralgia (TN) 3 years following microvascular decompression (MVD). The patient underwent brain magnetic resonance angiography (MRA), which did not reveal neurovascular compression; therefore surgical re-exploration was carried out. During the operation, the fifth cranial nerve was seen without impingement from any blood vessels; however, a ver…
Trigemināla neiralģija: ārstēšanas analīze pēc mikrovaskulāras dekompresijas ķirurģijas
2017
Ievads: Trigemināla neiralģija (TN) ir sindroms, kas izsauc ļoti stipras lēkmjveida sāpes, kas izstaro sejā un ko var raksturot kā durošus, līdzīgus elektriskai strāvai paraksizmus. Ir uzskatīts, ka TN etioloģijas pamatā ir hroniskais neirovaskulārais kontakts (t.s. neirovaskulārais konflikts) starp asinsvadu un nervu. Rezultātā asinsvads spiež uz nervu, veidojas nervu mielīna apvalka bojājums, pastāvīgs nervu šķiedru nociceptīvo receptoru kairinājums, kas izpaužas ar sāpēm. Visbiežāk patoloģiju diagnosticē diezgan vēli. Terapija sākumposmā ir Carbamazepine (CBZ), Un ja tas nav efektīvs, tad jādomā par operatīvo ārstēšanu. Ņemot vērā, ka vaskulārā kompresija ir visbiežākais iemesls primārai…
Intraparenchymal Brain Hemorrhage: "Birdlime" Effect Usefulness.
