Carotid stenting has grown considerably in the past decade as a viable and equivalent alternative to open surgery, called carotid artery endarterectomy (CAE). While both procedures are designed to open blocked carotid arteries in the neck, the minimally invasive technique of carotid artery stenting (CAS) has obvious appeal for patients. However, some patients are at higher risk with the stenting procedure and are better treated with surgery. How to identify those patients has been a matter of increased importance.
El activador del plasminógeno tisular (APT), un fármaco usado para combatir coágulos en pacientes de accidente cerebrovascular (ACV), no aumenta el riesgo de hemorragias peligrosas en pacientes que también toman el anticoagulante warfarina, halló una investigación reciente.
Las mujeres mayores con la arritmia conocida como fibrilación auricular se enfrentan a un riesgo de accidente cerebrovascular (ACV) 14 por ciento más elevado que los hombres con la misma afección, informan investigadores canadienses. El aumento en el riesgo permaneció incluso cuando las mujeres tomaban el anticoagulante warfarina (Coumadin) para prevenir el ACV, señalaron los autores del estudio.
BOSTON -- Performing non-thoracic MRI scans at 1.5 Tesla appears to be safe for patients with implantable cardioverter-defibrillators (ICDs) and pacemakers, a multicenter registry study showed.

Today at the European Stroke Conference in Lisbon, Portugal, Stryker announced the results of the TREVO 2 clinical trial. The study met the primary effectiveness endpoint, with the Trevo® Retriever achieving significantly better post-device revascularization than the Merci® Retriever (86.4% in the Trevo® Retriever arm compared to 60% in the Merci® Retriever arm). The rates of functional independence at 90 days for patients treated with the Trevo Retriever were also better than for the Merci® Retriever (40% mRS less than or equal to 2 compared to 21.8%). Other measures of performance also strongly favored the Trevo Retriever, including improvement in the National Institutes of Health Stroke Scale (NIHSS) and shorter hospital stays.
La radioterapia estereotáxica extracraneal (SBRT) es una técnica de irradiación muy prometedora, ya que en la mayoría de los estudios obtiene tasas de control local de más del 80 por ciento de las lesiones tratadas, y con mínima toxicidad, que ya está establecida como tratamiento de elección en pacientes no operables, con cáncer de pulmón en estadios precoces y que, aunque aún son necesarios más estudios, surge como alternativa interesante a otros tratamientos locales, de la que se pueden beneficiar pacientes con cáncer de próstata, tumores hepáticos, metástasis hepáticas, óseas, pulmonares, etc.
La Radiocirugía estereotáxica realizada con el protocolo de dosis moderadas que aplican. los especialistas del Grupo IMO, constituye un tratamiento eficaz y una modalidad terapéutica de elección para los pacientes que presentan malformaciones arteriovenosas de tronco cerebral. Asimismo, destaca la alta supervivencia obtenida que es del 88% a cinco y diez años desde que se inició el tratamiento. Estas han sido las conclusiones principales de un estudio que ha presentado el Dr. Luis Lorenzana, especialista en Neurocirugía de la Unidad de Oncología Radioterápica del Grupo IMO en el Hospital San Francisco de Asís de Madrid, con motivo del XVII Congreso Nacional de la Sociedad Española de Neurocirugía que se celebró en Las Palmas de Gran Canaria.
Using a modified ABCD risk score may be a better approach than the decades-old emergency department strategy of using subjective measures to assess dizzy patients for stroke, researchers suggested. The modified ABCD score -- which includes Age, Blood pressure, Clinical features, Diabetes, and Duration of symptoms -- was significantly higher for those presenting with dizziness who had cerebrovascular events than for those who did not have such events, reported Anthony S. Kim, MD, from the University of California in San Francisco, and colleagues.
Older women with atrial fibrillation are at increased risk for stroke compared with men who have the condition, according to a large Swedish cohort study. A database of more than 100,000 people diagnosed with atrial fibrillation revealed more ischemic strokes per year in women than men (6.2% versus 4.2%, P<0.0001), Leif Friberg, MD, from the Karolinska Institute in Stockholm, Sweden, and colleagues found.
A recently published study reports that delayed ipsilateral parenchymal haemorrhage may occur after the treatment of anterior circulation aneurysms with flow diverters. The study was published in the American Journal of Neuroradiology.
Baxano has announced that it has completed enrolment in its iO-Flex study which is a post-market clinical performance evaluation of the iO-Flex system used for decompressing patients diagnosed with moderate to severe lumbar spinal stenosis.
Results from the TREVO 2 clinical trial were presented by Raul Nogueira, Atlanta, USA, at the European Stroke Conference (Lisbon, Portugal, 22–25 May 2012). The study met the primary effectiveness endpoint, with the Trevo Retriever (Striker) achieving significantly better post-device revascularisation than the Merci Retriever (Striker) (86.4% in the Trevo Retriever arm compared to 60% in the Merci Retriever arm).
A study recently published in the American Journal of Neuroradiology (AJNR) has revealed that despite the fact that provision for emergency neurosurgical procedures is a mandatory component of centres that perform neuroendovascular procedures, the need for them is quite low.
Strokes are not just a medical condition of the advanced age – younger people can also be affected. But in this group, many strokes remain “silent” or symptoms are being misinterpreted. These findings from a large-scale European study were presented at the Meeting of the European Neurological Society in Prague.
