Endovascular treatment for a wide-neck anterior communicating artery (AcomA) aneurysm remains technically challenging. Stent-assisted embolization has been proposed as an alternative of treatment of complex aneurysms. The X-configuration double-stent-assisted technique was used to achieve successful coiling of wideneck AcomA aneurysm. Implanted stent can alter intraarterial flow. Follow-up angiograms 4 months later showed flow changes due to used X-technique of stents implantation and filling of the anterior cerebral artery from the opposite internal carotid artery.

Background and Purpose—The development of comprehensive stroke centers within hub-and-spoke stroke networks offers the opportunity to increase the proportion of acute ischemic stroke patients treated with intra-arterial therapies (IAT). Interhospital transfer delays will be critical in evaluating the success of this strategy. Stroke. 2011; 42: 1626-1630 Published online before print April 28, 2011.

Atherosclerotic intracranial arterial stenosis is an important cause of stroke that is increasingly being treated with percutaneous transluminal angioplasty and stenting (PTAS) to prevent recurrent stroke. However, PTAS has not been compared with medical management in a randomized trial. This article (10.1056/NEJMoa1105335) was published on September 7, 2011, at NEJM .org.

The objective of this study was to compare the cerebral embolic load of filter-protected versus proximal balloon– protected carotid artery stenting (CAS).

Background and Purpose—Oral anticoagulants are effective at reducing stroke compared with aspirin in atrial fibrillation patients older than 75 years. Although the benefits of reduced stroke risk outweigh the risks of bleeding, the cost effectiveness of warfarin in this patient population has not yet been established.

BACKGROUND AND PURPOSE: Patients with ruptured brain AVMs are at considerable risk of repeat hemorrhage, particularly when associated intranidal or flow-related aneurysms are present. There is controversy about the timing of diagnosis and treatment of patients with hemorrhagic stroke. We present our results of endovascular treatment of ruptured AVMs in the acute phase.

Background and Purpose—Acute ischemic stroke due to tandem occlusions of the extracranial internal carotid artery and intracranial arteries has a poor natural history. We aimed to evaluate our single-center experience with endovascular treatment of this unique stroke population. Stroke. 2011; 42: 1653-1657 Published online before print April 21, 2011.

La excelencia en la práctica clínica diaria exige la aplicación de decisiones médicas basadas en la evidencia científica. El nivel máximo de evidencia científica procede de estudios prospectivos multicéntricos aleatorizados que permitan una generalización de los resultados, extensibles a la comunidad científica. El adecuado diseño de dichos estudios, necesarios para la validación de toda nueva alternativa terapéutica, requiere la recopilación de información previa, obtenida de estudios de observación que se convierten, de este modo, en una fuente de información para la toma de decisiones en la práctica diaria; ello hasta disponer de los datos aportados por los estudios multicéntricos que, no obstante, deben interpretarse con cautela, ya que sus resultados no se extrapolan siempre a cualquier población y ámbito de ejercicio profesional.
