Cerebral Small Vessel Disease MRI Features Do Not Improve the Prediction of Stroke Outcome

چکیده
Objective To determine whether the total small vessel disease (SVD) score adds information to prediction of stroke outcome compared validated predictors, we tested different predictive models in patients with stroke. Methods White matter hyperintensity, lacunes, perivascular spaces, microbleeds, and atrophy were quantified 2 prospective datasets 428 197 first-ever stroke, using MRI collected 24 72 hours after onset. Functional, cognitive, psychological status assessed at 3- 6-month follow-up. The accuracy (in terms calibration discrimination) age, baseline NIH Stroke Scale (NIHSS), infarct volume was (model 1) on dataset 1, SVD added 2), improvement evaluated. These also developed for replication. Finally, model 3, features cerebral included rather than score. Results Model 1 showed excellent performance discriminating poor vs good functional outcomes (area under curve [AUC] 0.915), fair identifying cognitively impaired depressed (AUCs 0.750 0.688, respectively). A higher associated a poorer (odds ratio 1.30 [1.07–1.58], p = 0.0090 best outcome). However, adding 2) or individual 3) did not improve over 1. similar. Conclusions Cerebral independently functional, outcomes, but had no clinically relevant value predict when usual such as age NIHSS.

Prognostic Impact of Cerebral Small Vessel Disease on Stroke Outcome
Cerebral small vessel disease (SVD), which includes white matter hyperintensities (WMHs), silent brain infarction (SBI), and cerebral microbleeds (CMBs), develops in a conjunction of cumulated injuries to cerebral microvascular beds, increased permeability of blood-brain barriers, and chronic oligemia. SVD is easily detected by routine neuroimaging modalities such as brain computed tomography o...
متن کاملThrombolysis in acute stroke patients with cerebral small vessel disease.
BACKGROUND Thrombolytic treatment is of proven benefit in acute ischemic stroke. The term cerebral small vessel disease (SVD) refers to a group of pathological processes affecting the small arteries, arterioles, venules and capillaries of the brain, and encompasses both ischemic and hemorrhagic lesions. Lacunar stroke, an expression of SVD, is associated with an unfavorable long-term prognosis ...
متن کاملPopulation Imaging of Cerebral Small Vessel Disease
Background – We previously reported on the high prevalence of cerebral micro bleeds (CMBs) in community-dwelling people aged 60 years and older. Moreover, we found that their spatial distribution likely reflects differences in underlying etiology. We have since almost quadrupled the number of participants in our study and expanded it to include persons of 45 years and older. We examined the pre...
متن کاملAdvanced Neuroimaging of Cerebral Small Vessel Disease
OPINION STATEMENT Cerebral small vessel disease (SVD) is characterised by damage to deep grey and white matter structures of the brain and is responsible for a diverse range of clinical problems that include stroke and dementia. In this review, we describe advances in neuroimaging published since January 2015, mainly with magnetic resonance imaging (MRI), that, in general, are improving quantif...
