Manejo de la trombosis venosa cerebral en España: estudio descriptivo MOTIVATE / Management of cerebral venous thrombosis in Spain: MOTIVATE descriptive study

Introducción: La trombosis venosa cerebral (TVC) es una causa poco común de ictus que afecta principalmente a adultos jóvenes. Un diagnóstico precoz y preciso puede reducir la tasa y gravedad de las complicaciones. Objetivo: Analizar las características clínicas, manejo y tratamiento de la TVC en diferentes centros de nuestro país. Métodos: Estudio descriptivo retrospectivo multicéntrico de pacientes hospitalizados por TVC entre 2008 y 2017 en 11 centros sanitarios en nuestro país. Resultados: Se incluyeron 256 pacientes, edad media 49,8 ± 18,7 años y el 51% fueron mujeres. Los síntomas más frecuentes fueron: cefalea (73%), déficits focales (50%), crisis epilépticas (33%) y encefalopatía (21%). Las localizaciones más frecuentes fueron: seno longitudinal superior (12,5%), transverso (10,9%) y afectación de dos o más senos o venas (66,4%). La etiología conocida más frecuente fue la trombofilia (24%), siendo la mutación de la protrombina G20210A la más común (19%). El 46% fue tratado con antitrombóticos durante 3-6 meses, el 21% durante un año y un 22,6% de los pacientes requirieron anticoagulación indefinida. En un 5% de los sujetos fue preciso terapia endovascular y un 33% requirió neurocirugía. En relación al pronóstico, el 75% fueron independientes a los 3 meses con una puntuación en la escala de Rankin modificada (mRS) ≤ 2 y la presencia de papiledema (p = 0,03), déficit focal (p = 0,001) y encefalopatía (p < 0,001) se relacionaron significativamente con mal pronóstico (mRS > 3). La tasa de mortalidad intrahospitalaria fue del 4,3% y el 6,3% de los pacientes fallecieron a los 3 meses. Conclusión:La diversidad de factores de riesgo y la presentación variable suponen un desafío en el diagnóstico y tratamiento de la TVC. Para mejorar el pronóstico y reducir la mortalidad es fundamental la instauración de protocolos en el manejo de esta patología.(AU)

Introduction: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults. Early, accurate diagnosis can reduce the rate and severity of complications. Objective: The aim of this study was to analyse the clinical characteristics, management, and treatment of CVT in different centres in Spain. Methods: We conducted a multicentre, retrospective, descriptive study of patients hospitalised due to CVT between 2008 and 2017 at 11 Spanish centres. Results: We included 256 patients, with a mean age (SD) of 49.8 (18.7) years; 51% of patients were women. The most frequent symptoms were headache (73%), focal deficits (50%), epileptic seizures (33%), and encephalopathy (21%). The most frequent localisations were the superior sagittal sinus (12.5%), the transverse sinus (10.9%), and 2 or more sinuses or veins (66.4%). Thrombophilia was the most frequent known aetiology (24%), and was most commonly associated with the prothrombin G20210A mutation (19%). Forty-six percent of patients were treated with antithrombotics for 3-6 months, 21% for one year, and 22.6% required indefinite anticoagulation. Endovascular therapy was performed in 5% of cases, and 33% required neurosurgery. Regarding outcomes, 75% of patients were independent at 3 months (modified Rankin Scale [mRS] score ≤ 2), with papilloedema (P = .03), focal deficits (P = .001), and encephalopathy (P < .001) showing a statistically significant association with poor prognosis (mRS > 3). The in-hospital mortality rate was 4.3%, with a 3-month mortality rate of 6.3%. Conclusion: The diverse risk factors and variable presentation of CVT represent a challenge in the diagnosis and treatment of this condition. To improve prognosis and reduce mortality, it is essential to establish management protocols for this entity.(AU)

Impact of a series of measures for optimisation hospital code stroke care on door-to-needle times.

INTRODUCTION: Time continues to be a fundamental variable in reperfusion treatments for acute ischaemic stroke. Despite the recommendations made in clinical guidelines, only around one-third of these patients receive fibrinolysis within 60minutes. In this study, we describe our experience with the implementation of a specific protocol for patients with acute ischaemic stroke and evaluate its impact on door-to-needle times in our hospital. METHODS: Measures were gradually implemented in late 2015 to shorten stroke management times and optimise the care provided to patients with acute ischaemic stroke; these measures included the creation of a specific on-call neurovascular care team. We compare stroke management times before (2013-2015) and after (2017-2019) the introduction of the protocol. RESULTS: The study includes 182 patients attended before implementation of the protocol and 249 attended after. Once all measures were in effect, the overall median door-to-needle time was 45minutes (vs 74 minutes before, a 39% reduction; P<.001), with 73.5% of patients treated within 60minutes (a 47% increase; P<.001). Median overall time to treatment (onset-to-needle time) was reduced by 20minutes (P<.001). CONCLUSIONS: The measures included in our protocol achieved a significant, sustained reduction in door-to-needle times, although there remains room for improvement. The mechanisms established for monitoring outcomes and for continuous improvement will enable further advances in this regard.

Impacto en los tiempos puerta-aguja de un conjunto de medidas para optimizar la atención hospitalaria del código ictus / Impact of a series of measures for optimisation hospital code stroke care on door-to-needle times

Introducción: El tiempo sigue siendo una variable determinante para los tratamientos de reperfusión del ictus isquémico agudo. A pesar de las recomendaciones de las guías clínicas, solo alrededor de la tercera parte de los pacientes con ictus isquémico agudo son fibrinolizados en ≤ 60 min. El objetivo de este trabajo es describir nuestra experiencia implementando un protocolo específico de atención del ictus isquémico agudo y evaluar su impacto en nuestros tiempos puerta-aguja.MétodosA finales del 2015, se implantaron gradualmente unas medidas diseñadas para acortar los tiempos de actuación y optimizar la atención del ictus isquémico agudo incluyendo una guardia específica de Neurovascular. Se compararon los tiempos de actuación antes (2013-2015) y después (2017-2019) de la introducción de este protocolo.ResultadosSe incluyó a 182 pacientes antes y 249 después de la intervención. Cuando todas las medidas fueron introducidas, la mediana global de tiempo puerta-aguja fue de 45 min (previa 74 min, 39% menos, p < 0,001) con un 73,5% de pacientes tratados en ≤ 60 min (47% más que preintervención, p < 0,001). El tiempo global al tratamiento (inicio síntoma-aguja) se redujo en 20 min de mediana (p < 0,001).ConclusionesLas medidas asociadas en nuestro protocolo han conseguido una disminución del tiempo puerta-aguja de forma significativa y sostenida, aunque todavía nos queda margen de mejora, la dinámica establecida de control de resultados y mejora continua hará posible seguir avanzando en este sentido.

Incidence, outcomes, and associated factors of isolated striatocapsular infarct after mechanical thrombectomy.

OBJECTIVE: To describe baseline and procedural characteristics and clinical outcomes of isolated striatocapsular infarct (iSCI) after mechanical thrombectomy in patients with large-vessel occlusion of the anterior cerebral circulation and its clinical outcome. METHODS: We performed a longitudinal study including all patients treated with mechanical thrombectomy at our centre between 2015 and 2017; patients were divided into 2 groups (iSCI and non-iSCI) according to whether they presented iSCI in a control CT scan at 24 hours. RESULTS: Of the 83 patients identified, 22.9% developed an iSCI. There were no statically significant differences in baseline characteristics or in reperfusion times. Patients presenting iSCI showed better collateral circulation and better reperfusion rates in the bivariate analysis. No significant difference was observed for mortality at discharge or at 3 months, or for functional prognosis at 3 months. CONCLUSIONS: Even if successful reperfusion is achieved, iSCI is a common sequela, independently of reperfusion time, especially in patients with good collateral circulation.

[Influence of mechanical thrombectomy on the incidence of isolated striatocapsular infarction and a description of its clinical characteristics]. / Influencia de la trombectomia mecanica en la incidencia de infarto estriatocapsular aislado y descripcion de sus caracteristicas clinicas.

INTRODUCTION: The great vulnerability of the striatocapsular region to ischaemia means that mechanical thrombectomy has its limitations in occlusions of large-calibre vessels when it comes to preventing the striatocapsular region from undergoing infarction. AIMS: To analyse the effect of endovascular treatment on the incidence of isolated striatocapsular infarction (iSCI) and to describe its clinical characteristics. PATIENTS AND METHODS: We conducted a retrospective study to analyse the incidence of iSCI following treatment of cerebral reperfusion. The baseline and clinical characteristics of the patients identified with iSCI and the incidence of iSCI is compared between two groups according to the availability of mechanical thrombectomy: one (pre-thrombectomy group) that received intravenous fibrinolysis as the only treatment for cerebral reperfusion available in that moment; and another (post-thrombectomy group) that received a mechanical thrombectomy with or without intravenous fibrinolysis. RESULTS: Of the 390 patients who received reperfusion, 8.2% had iSCI. Of the 135 patients treated with intravenous fibrinolysis, 4.4% (n = 6) developed iSCI (pre-thrombectomy group), and of the 255 patients treated in the post-thrombectomy group, iSCI was observed in 10.2%. The statistical analysis of the incidence of iSCI between the two groups showed significant differences (p = 0.034). A sensory-motor clinical picture was the most frequent among the patients with iSCI (63.33%), with a frequency of cortical symptoms of 55.17%. CONCLUSIONS: According to the data, there has been an increase in the incidence of iSCI in our setting following the establishment of mechanical thrombectomy.

TITLE: Influencia de la trombectomia mecanica en la incidencia de infarto estriatocapsular aislado y descripcion de sus caracteristicas clinicas.Introduccion. La gran vulnerabilidad a la isquemia de la region estriatocapsular hace que la trombectomia mecanica tenga sus limitaciones en las oclusiones de vaso de gran calibre a la hora de evitar que la region estriatocapsular se infarte. Objetivos. Analizar el efecto del tratamiento endovascular en la incidencia de infarto estriatocapsular aislado (IECa) y describir sus caracteristicas clinicas. Pacientes y metodos. Estudio retrospectivo en el que se analiza la incidencia de IECa tras el tratamiento de reperfusion cerebral. Se describen las caracteristicas basales y clinicas de los pacientes identificados con IECa y se compara la incidencia del IECa entre dos grupos segun la disponibilidad de trombectomia mecanica: uno (grupo pretrombectomia) que recibio fibrinolisis intravenosa como unico tratamiento de reperfusion cerebral disponible en ese momento, y otro (grupo postrombectomia) que recibio trombectomia mecanica con o sin fibrinolisis intravenosa. Resultados. Del total de 390 pacientes reperfundidos, un 8,2% tuvo un IECa. De 135 pacientes tratados con fibrinolisis intravenosa, un 4,4% (n = 6) desarrollo un IECa (grupo pretrombectomia), y de 255 pacientes tratados en el grupo postrombectomia, se visualizo IECa en un 10,2%. El analisis estadistico de la incidencia de IECa entre ambos grupos mostro diferencias significativas (p = 0,034). La clinica sensomotora fue la mas frecuente entre los pacientes con IECa (63,33%), con una frecuencia de sintomas corticales de un 55,17%. Conclusiones. Segun los datos, hemos presenciado un aumento en la incidencia de IECa en nuestro medio tras la instauracion de la trombectomia mecanica.
