Tratamiento de reperfusión en el ictus isquémico agudo por disección arterial cervicocerebral: descripción de los resultados de un estudio nacional multicéntrico / Reperfusion treatment in acute ischaemic stroke due to cervical and cerebral artery dissection: results of a Spanish national multicentre study

Introducción: El ictus isquémico (II) por disección arterial cervicocerebral (DAC) es una entidadinfrecuente y existen pocos datos sobre el uso de terapias de reperfusión como la fibrinólisis intravenosa y la trombectomía mecánica. Se analizó el uso de dichas terapias en pacientes conII por DAC y se comparó con aquellos pacientes reperfundidos con II por otras causas.Método: Estudio observacional retrospectivo multicéntrico de pacientes con II por DAC basadoen el Registro Nacional de Ictus de la Sociedad Espa˜nola de Neurología durante el periodo 2011-2019. Se realizaron análisis comparativos entre: a) pacientes con DAC tratados y no tratados conterapias de reperfusión y b) pacientes reperfundidos con II por DAC y pacientes reperfundidoscon II por otras causas. Se incluyeron variables epidemiológicas, del ictus y resultados al alta ya los 3 meses.Resultados: Un total de 21.037 pacientes con II fueron incluidos; 223 (1%) fueron por DAC y 68(30%) recibieron tratamiento de reperfusión. El uso de tratamientos de reperfusión fue menor enlos casos de DAC de arteria vertebral y mayor en los casos de oclusión carotídea. Los pacientescon II por DAC reperfundidos respecto a aquellos con II reperfundidos por otras causas fueronmás jóvenes, la trombectomía mecánica se utilizó más y la fibrinólisis intravenosa menos. Lascomplicaciones hemorrágicas, la mortalidad y la autonomía a los 3 meses fueron similares.Conclusiones: Las terapias de reperfusión se usan con frecuencia en los pacientes con II porDAC. Los resultados demuestran eficacia y seguridad y son equiparables a los pacientes tratadoscon terapias de reperfusión por II de otras causas.(AU)

Introduction: Ischaemic stroke (IS) due to cervical and cerebral artery dissection (CAD) is arare entity, and few data are available on the use of such reperfusion therapies as intravenousfibrinolysis and mechanical thrombectomy in these patients. We analysed the use of these treat-ments in patients with IS due to CAD and compared them against patients receiving reperfusiontreatment for IS of other aetiologies.Method: We conducted an observational, retrospective, multicentre study of patients with ISdue to CAD recorded in the National Stroke Registry of the Spanish Society of Neurology duringthe period 2011-2019. Comparative analyses were performed between: a) patients with CADtreated and not treated with reperfusion therapies and b) patients treated with reperfusion forIS due to CAD and patients treated with reperfusion for IS due to other causes. Epidemiologicaldata, 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 whom68 (30%) received reperfusion treatment. Reperfusion treatments were used less frequently incases of vertebral artery dissection and more frequently in patients with carotid artery occlu-sion. Compared to patients with IS due to other causes, patients with CAD were younger, morefrequently underwent mechanical thrombectomy, and less frequently received intravenous fibri-nolysis. Rates of haemorrhagic complications, mortality, and independence at 3 months weresimilar in both groups.Conclusions: Reperfusion therapy is frequently used in patients with IS due to CAD. The outco-mes of these patients demonstrate the efficacy and safety of reperfusion treatments, and arecomparable to the outcomes of patients with IS due to other aetiologies.(AU)

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.

Attention to acute cerebrovascular disease in Guipúzcoa: description of the results of a reference hospital in a centralized care model.

INTRODUCTION: In the last 15 years, considerable improvements have been made in acute stroke care in Guipuzkoa, including the implementation of a centralised care model at Hospital Universitario Donostia (HUD), improved coordination between professionals, early detection campaigns, new treatments, a stroke unit, and specific rehabilitation. The aim of this work is to describe the results of a reference hospital (HUD) in a centralised care model. MATERIAL AND METHODS: We performed a retrospective observational study of a sample of patients discharged between August and December 2015 from the HUD with a diagnosis of acute stroke (ICD-9-CM codes 430-436, except 433.10). We review patients' baseline characteristics, acute-phase care, and functional outcomes and mortality at discharge and at one year. RESULTS AND DISCUSSION: We identified 536 patients, with a mean age of 73.6 years and a high comorbidity rate. Ischaemic stroke accounted for 64.8% of patients, followed by haemorrhagic stroke (20%) and transient ischaemic attack (14.8%). A total of 53% of patients were attended in < 6 hours, with code stroke being activated in 37.1%; 52.2% of patients were admitted to the stroke unit. Intravenous therapy was administered to 8.3% of patients with ischaemic stroke, and 9.5% underwent mechanical thrombectomy. Surgery was performed in 12.1% patients with haemorrhagic stroke. Rehabilitation was started at hospital in 56% of patients, and 39.6% continued with this treatment at discharge. Mortality was 13.8% at discharge and 25.9% at one year (ischaemic stroke, 25.3%; haemorrhagic stroke, 47.5%); these figures are lower than those previously reported in Guipuzkoa. At one year, 62.5% of patients had a Barthel Index score of 95-100, and 50% a modified Rankin Scale score of 0-2. CONCLUSIONS: After the strategic changes implemented in acute stroke care in Guipuzkoa, including the centralisation of the acute stroke care model, mortality rates at discharge and at one year are lower in 2015 than the previously reported rates, with similar rates of independence. These results are consistent with those published by other Spanish and European centres.

Atención a la enfermedad cerebrovascular aguda en Guipúzcoa: descripción de los resultados de un hospital de referencia en un modelo de atención centralizado / Attention to acute cerebrovascular disease in Guipúzcoa: Description of the results of a reference hospital in a centralized care model

Introducción: En los últimos 15 años se han introducido importantes mejoras en la atención de la enfermedad cerebrovascular aguda (ECVA) en Guipúzcoa, que incluyen la implementación de un modelo centralizado en el Hospital Universitario Donostia (HUD), una mejor coordinación entre profesionales, campañas para su detección precoz, nuevos tratamientos, Unidad de Ictus y una rehabilitación específica. El objetivo de este trabajo es describir los resultados de un hospital de referencia (HUD) en un modelo de atención centralizado. Material y métodos: Estudio observacional retrospectivo de una muestra de pacientes dados de alta en el periodo de agosto-diciembre del año 2015 del HUD con diagnóstico de ECVA (CIE-9-MC-430-436 excepto 43310). Revisión de las características basales, atención en fase aguda y resultados funcionales y de mortalidad al alta y al año. Resultados y discusión: Se incluyó a 536 pacientes cuya media de edad fue de 73,6 años y cuya comorbilidad era elevada. El ictus isquémico supuso el 64,8% de las altas, seguido de la ECVA hemorrágica (20%) y del accidente isquémico transitorio (14,8%). Se atendió en < 6 h a un 53% de pacientes, activándose el «código ictus» en un 37,1%. Un 52,2% ingresó en la Unidad de Ictus. Un 11,34% de los pacientes con ictus isquémico recibió terapia por vía intravenosa y un 9,5% trombectomía mecánica. Un 12,1% de los pacientes con ECVA hemorrágica fue intervenido quirúrgicamente. El 56% inició rehabilitación en el hospital y un 39,6% la mantuvo al alta. La mortalidad al alta fue de un 13,8% y al año de un 25,9% (ictus isquémico: 25,3% y ECVA hemorrágica: 47,5%), menor a la descrita previamente en Guipúzcoa. Al año, un 62,5% de los pacientes tenían un ÿndice de Barthel 95-100 y un 50% una puntuación en escala de Rankin modificada 0-2. [...] (AU)
