Neuralgia del trigémino y del glosofaríngeo concomitantes, asíncronas y refractarias. Buena respuesta al abordaje quirúrgico en un tiempo / Concomitant, asynchronous and refractory trigeminal and glossopharyngeal neuralgia. Good response to surgical approach in one time

Introducción: La cirugía de descompresión microvascular (DMV) es el tratamiento de elección de una neuralgia craneal refractaria secundaria a compresión vascular. Las neuralgias simultáneas de dos pares craneales son extremadamente infrecuentes. Describimos un caso con neuralgia concomitante del trigémino (NT) y glosofaríngeo (NG) refractarias y secundarias a cruce neurovascular abordadas quirúrgicamente en un mismo tiempo. Caso clínico: Mujer de 65 años con NT derecho (inicialmente en V2-V3) desde 2004 con control regular con carboxamidas. Diecisiete años después empeoraron los paroxismos en V2-V3, aparecieron también en V1 y en el territorio del nervio glosofaríngeo derecho (oído derecho y fosa amigdalar al hablar y deglutir). La resonancia magnética cerebral mostró contacto arterial significativo entre arteria cerebelosa superior (ACS) con origen del V par craneal derecho y de la arteria cerebelosa antero-inferior (AICA) con el origen de pares craneales bajos derechos. Se realizó DMV de ambos pares craneales en un mismo tiempo quirúrgico mediante craniectomía retrosigmoidea, y se procedió a la liberación del V par craneal, en contacto íntimo con la ACS, y del IX par craneal en contacto con la AICA derecha, para lo que se puso teflón entre ellas. La paciente tuvo una resolución inmediata de los paroxismos trigeminales y una mejoría considerable en intensidad y frecuencia de los glosofaríngeos. A los 2 años de la intervención continúa la desescalada de tratamiento neuromodulador con buena respuesta.ConclusiónLa DMV en la NT y NG simultáneas es factible y puede ofrecer un buen resultado posquirúrgico.

INTRODUCTION: Microvascular decompression (MVD) surgery is the first choice treatment for refractory cranial neuralgia secondary to vascular compression. Simultaneous neuralgia of two cranial nerves is extremely rare. We describe a case of concomitant refractory trigeminal (TN) and glossopharyngeal (GN) neuralgia secondary to neurovascular crossover, treated surgically at the same time. CASE REPORT: 65-year-old woman with right TN (initially V2-V3) since 2004 with regular control with carboxamides. Seventeen years later, paroxysms worsened in V2-V3, also appearing in V1 and in the territory of the right glossopharyngeal nerve (right ear and tonsillar fossa when speaking and swallowing). Cerebral MRI showed significant arterial contact between the superior cerebellar artery (SCA) with the origin of the right V cranial nerve and the antero-inferior cerebellar artery (AICA) with the origin of the right lower CCNN. MVD of both cranial nerves was performed at the same surgical time by means of retrosigmoid craniectomy, releasing the V cranial nerve, in intimate contact with the SCA, and the IX cranial nerve in contact with the right AICA, interposing teflon between them. The patient had an immediate resolution of the trigeminal paroxysms and a dramatic improvement in intensity and frequency of glossopharyngeal paroxysms. Two years after the intervention, de-escalation of neuromodulator treatment continues with good response. CONCLUSION. MVD in simultaneous TN and GN is feasible and can offer a good post-surgical outcome. (AU)

Reperfusion therapy in acute ischaemic stroke due to cervical and cerebral artery dissection: Results from a Spanish multicentre study.

INTRODUCTION: Ischaemic stroke (IS) due to cervical and cerebral artery dissection (CAD) is a rare entity, and few data are available on the use of such reperfusion therapies as intravenous fibrinolysis and mechanical thrombectomy in these patients. We analysed the use of these treatments in patients with IS due to CAD and compared them against patients receiving reperfusion treatment for IS of other aetiologies. METHODS: We conducted an observational, retrospective, multicentre study of patients with IS due to CAD recorded in the National Stroke Registry of the Spanish Society of Neurology during the period 2011-2019. Comparative analyses were performed between: a) patients with CAD treated and not treated with reperfusion therapies and b) patients treated with reperfusion for IS due to CAD and patients treated with reperfusion for IS due to other causes. Epidemiological data, stroke variables, and outcomes at discharge and at 3 months were included in the analysis. RESULTS: The study included 21,037 patients with IS: 223 (1%) had IS due to CAD, of whom 68 (30%) received reperfusion treatment. Reperfusion treatments were used less frequently in cases of vertebral artery dissection and more frequently in patients with carotid artery occlusion. Compared to patients with IS due to other causes, patients with CAD were younger, more frequently underwent mechanical thrombectomy, and less frequently received intravenous fibrinolysis. Rates of haemorrhagic complications, mortality, and independence at 3 months were similar in both groups. CONCLUSIONS: Reperfusion therapy is frequently used in patients with IS due to CAD. The outcomes of these patients demonstrate the efficacy and safety of reperfusion treatments, and are comparable to the outcomes of patients with IS due to other aetiologies.

Ischaemic stroke as a complication of cardiac catheterisation. Clinical and radiological characteristics, progression, and therapeutic implications.

INTRODUCTION: Ischaemic stroke is the most common neurological complication of cardiac catheterisation. This study aims to analyse the clinical and prognostic differences between post-catheterisation stroke code (SC) and all other in-hospital and prehospital SC. METHODS: We prospectively recorded SC activation at our centre between March 2011 and April 2016. Patients were grouped according to whether SC was activated post-catheterisation, in-hospital but not post-catheterisation, or before arrival at hospital; groups were compared in terms of clinical and radiological characteristics, therapeutic approach, functional status, and three-month mortality. RESULTS: The sample included 2224 patients, of whom 31 presented stroke post-catheterisation. Baseline National Institutes of Health Stroke Scale score was lower for post-catheterisation SC than for other in-hospital SC and pre-hospital SC (5, 10, and 7, respectively; P=.02), and SC was activated sooner (50, 100, and 125minutes, respectively; P<.001). Furthermore, post-catheterisation SC were more frequently due to transient ischaemic attack (38%, 8%, and 9%, respectively; P<.001) and less frequently to proximal artery occlusion (17.9%, 31.4%, and 39.2%, respectively; P=.023). The majority of patients with post-catheterisation strokes (89.7%) did not receive reperfusion therapy; 60% of the patients with proximal artery occlusion received endovascular treatment. The mortality rate was 12.95% for post-catheterisation strokes and 25% for all other in-hospital strokes. Although patients with post-catheterisation stroke had a better functional prognosis, the adjusted analysis showed that this effect was determined by their lower initial severity. CONCLUSIONS: Post-catheterisation stroke is initially less severe, and presents more often as transient ischaemic attack and less frequently as proximal artery occlusion. Most post-catheterisation strokes are not treated with reperfusion; in case of artery occlusion, mechanical thrombectomy is the preferred treatment.
