Carotid web (CaW) is a cause of recurrent ischemic stroke that remains underdiagnosed using Duplex ultrasound (DUS). Improved methods and description its ultrasound's features could allow better detection CaW. Ultrasound microflow imaging (MFI) blood flow technique sensitive to slow increase CaW detection. This study aimed describe B-mode MFI.In retrospective monocentric study, patients with on CT angiography who underwent DUS examination carotid arteries were included. was performed by two...
Background: Whether bridging therapy (intravenous thrombolysis [IVT] followed by mechanical thrombectomy) is superior to IVT alone in minor stroke with large vessel occlusion unknown. Perfusion imaging may identify subsets of occlusion–related patients distinct response therapy. Methods: We conducted a multicenter international observational study consecutive IVT-treated (National Institutes Health Stroke Scale score ≤5) who had an anterior circulation and perfusion performed before IVT,...
Background A target mismatch profile can identify good clinical response to recanalization after acute ischemic stroke, but does not consider region specificities. Purpose To test whether location-weighted infarction core and mismatch, determined from diffusion perfusion MRI performed in patients with could improve prediction of mechanical thrombectomy compared a profile. Materials Methods In this secondary analysis, two prospectively collected independent stroke data sets (2012-2015...
Background and aims: Cerebral small vessel disease (CSVD) is the main cause of intracerebral hemorrhage (ICH) in older individuals but has not been systematically studied younger people. We aimed to evaluate prevalence characteristics CSVD young adults with symptomatic ICH. Methods: conducted a cohort study consecutive aged 18–50 years non-traumatic All patients were evaluated brain vascular imaging. Using validated imaging markers (cerebral microbleeds (CMBs), white matter hyperintensities...
Determining the mechanism of large vessel occlusion related acute ischemic stroke is major importance to initiate a tailored secondary prevention strategy. We investigated using atherosclerosis, small disease, cardiac source, other cause, dissection (ASCOD) classification distribution causes treated by mechanical thrombectomy.This was predefined substudy FRAME (French Acute Multimodal Imaging Select Patient for Mechanical Thrombectomy). Each patient underwent systematic etiological workup...
Background: Collateral circulation plays a key role in acute ischemic stroke. We sought to determine the association between arterial collateral status, estimated by Hypoperfusion Intensity Ratio (HIR) on perfusion MRI, and stroke etiology anterior large vessel occlusion (LVO). Methods: retrospectively analyzed LVO patients with baseline MRI performed within 24 h from symptom onset. To avoid selection bias, were chosen (1) prospective registry of one comprehensive center that included both...
