Favorable Bridging Therapy Based on DWI-FLAIR Mismatch in Patients with Unclear-Onset Stroke.
BACKGROUND AND PURPOSE Standard selection criteria for revascularization therapy usually exclude patients with unclear-onset stroke. Our aim was to evaluate the efficacy and safety of revascularization therapy in patients with unclear-onset stroke in the anterior circulation and to identify the predictive factors for favorable clinical outcome. MATERIALS AND METHODS We retrospectively analyze...
متن کاملDWI Intensity Values Predict FLAIR Lesions in Acute Ischemic Stroke
BACKGROUND AND PURPOSE In acute stroke, the DWI-FLAIR mismatch allows for the allocation of patients to the thrombolysis window (<4.5 hours). FLAIR-lesions, however, may be challenging to assess. In comparison, DWI may be a useful bio-marker owing to high lesion contrast. We investigated the performance of a relative DWI signal intensity (rSI) threshold to predict the presence of FLAIR-lesions ...
متن کاملDifficulty of MRI Based Identification of Lesion Age by Acute Infra-Tentorial Ischemic Stroke
BACKGROUND Systemic thrombolysis in acute ischemic stroke is restricted to the 4.5 h time window. Many patients are excluded from this treatment because symptom onset is unknown. Magnetic resonance imaging (MRI) studies have shown that stroke patients presenting with acute supra-tentorial diffusion-weighted imaging (DWI) lesions that do not have matching lesions on fluid attenuated inversion re...

15 صفحه اولEndovascular treatment of acute ischemic stroke may be safely performed with no time window limit in appropriately selected patients.
BACKGROUND AND PURPOSE The traditional time window for acute ischemic stroke intra-arterial therapy (IAT) is <6 hours, which is based on pharmacological thrombolysis without penumbral imaging. This study was conducted to determine the safety of patient selection for IAT based on perfusion mismatch rather than time. METHODS A cohort of consecutive patients treated with IAT was identified by da...
