Introduction: Intraventricular hematoma (IVH) occurs in approximately 40% of acute intracerebral hemorrhage (ICH) patients and is significantly associated with worse clinical outcomes. According to cerebrospinal fluid dynamics, some blood within the ventricles may circulate through subarachnoid spaces, leading its apparent “disappearance” on follow-up imaging. We aim investigate association between initial IVH involvement significant early ICH retraction at Methods: Data are from MCAHP...
Abstract Background and purpose The ANNEXA‐4 trial measured hemostatic efficacy of andexanet alfa in patients with major bleeding taking factor Xa inhibitors. A proportion this was traumatic nontraumatic intracranial bleeding. Different measurements were applied the including volumetrics to assess for depending on compartment involved. We aimed determine most reliable way measure hemorrhage (ICrH) volume by comparing individual brain total ICrH volume. Methods Thirty randomly selected from...
<h3>BACKGROUND AND PURPOSE:</h3> The presence of spot sign is associated with a high risk hematoma growth. Our aim was to investigate the timing appearance, volume, and leakage rate for predicting growth in acute intracerebral hemorrhage using multiphase CTA. <h3>MATERIALS METHODS:</h3> In this single-center retrospective study, CTA 3 phases performed (defined as intraparenchymal ± intraventricular hemorrhages). Phases first volumes (microliter), rates among (microliter/second) were...
Background Manual segmentations of intracranial hemorrhage on non-contrast CT images are the gold-standard in measuring hematoma growth but prone to rater variability. Aims We demonstrate that a convex optimization-based interactive segmentation approach can accurately and reliably measure growth. Methods Baseline 16-h follow-up head 46 subjects presenting with were selected randomly from ANNEXA-4 trial imaging database. Three users semi-automatically segmented volume for each timepoint...
Background: Existing radiological markers of hematoma expansion (HE) show modest predictive accuracy. We aim to investigate a novel marker that co-localizes findings from non-contrast CT (NCCT) and angiography (CTA) predict HE. Methods: Consecutive acute intracerebral hemorrhage patients admitted at Foothills Medical Centre in Calgary, Canada, were included. The Black-&-White sign was defined as any visually identified spot on CTA co-localized with hypodensity the corresponding NCCT....
ABSTRACT BACKGROUND AND PURPOSE Manual segmentation of infarct volume on follow‐up MRI diffusion‐weighted imaging (MRI‐DWI) is considered the gold standard but prone to rater variability. We assess variability manual segmentations MRI‐DWI volume. METHODS Consecutive patients (May 2018 May 2019) with anterior circulation stroke and endovascularly treated were enrolled. All underwent 24‐ 32‐hour MRI. Three users manually segmented DWI volumes slice by twice. The reference was generated STAPLE...
Background: Direct teleconsultations between emergency medical services (EMS) crews and hospital-based stroke neurologists are mandated in the Czech Republic as triage prenotification tool acute patients. The main aim of this study was to analyze efficacy well quality such daily clinical practice. Methods: This is a descriptive analysis EMS paramedic geographically defined region (Moravian-Silesian region) October 2018 December 2018. All were analyzed for length content. Content included...
Syndrom a. choroidea anterior je vzácný klinický syndrom sestávající ne z triády: kontralaterální hemiparéza/hemiplegie, hemianestezie a homonymní hemianopsie, rozvíjející se nejčastěji na pokladě mozkového infarktu v povodí stejnojmenné tepny
Background: CTA spot sign is a predictor of intracerebral hemorrhage (ICH) expansion. This can fluctuate in appearance, volume, and timing. Multiphase (mCTA) identify through 3 time-resolved images. We sought to novel follow up total hematoma expansion using mCTA. Methods: cohort study included patients with ICH between 2012-2019. Quantomo software was used measure volume (ml) from baseline CT & follow-up CT/MRI blinded mCTA phases. Spot calculated by subtracting 1 st phase 2 nd measured...
