Manisha KY, Varma R, Sylaja PN, Sreedharan SE. Progressive lacunar strokes behave differently from stable ones even at one year-An observational study. J Stroke Cerebrovasc Dis 2023; 32:107434. [PMID: 37871400 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 09/11/2023] [Accepted: 10/18/2023] [Indexed: 10/25/2023] Open
Abstract
BACKGROUND AND AIMS Small fraction of lacunar stroke patients have an early fluctuating course, described as progressive lacunar syndrome [PLS].We studied the predictors and short term outcome of progressive lacunar strokes in comparison with those with an early stable course. MATERIALS AND METHODS Single centre retrospective study where patients with lacunar strokes from 2016 to 2020 were included in the study. Progression was defined as increase in stroke severity [NIHSS] by ≥2 points from baseline without imaging evidence of new infarcts or haemorrhagic transformation. We compared the clinical variables, risk factors, imaging, treatment received and 1 year outcome of subjects with PLS with those with a stable course, with modified Rankin score 0-2 taken as good outcome. RESULTS Of the 216 patients with a mean age 63.17 years, progressive course was noted in 56 subjects [26 %].Majority of the fluctuations occurred within 24 h of onset of symptoms. Though stroke severity at admission was comparable between the 2 groups, discharge and 1 year outcome was poorer in those with an early progressive course. We found that presentation as pure motor syndrome, hypertriglyceridemia and thrombolytic therapy were predictors of poor outcome in progressive lacunar strokes, while age, risk factors, infarct location or leukoaraiosis failed to show an association. Thalamic infarcts and atypical lacunar syndromes were associated with a stable course. CONCLUSION Progressive course is seen in a quarter of lacunar strokes and they have poorer outcome at 1 year. Our finding of thrombolysis being associated with worse outcome in PLS patients, should alert physicians regarding need for more definitive therapies for this condition.

Abstract
In single subcortical infarction (SSI), changes in lesion size are a major determinant of early neurological deterioration. We evaluated the association between END and infarct growth velocity (IGV) in patients with SSI. We included consecutive patients with SSI who underwent MRI within 24 h of symptom onset between 2010 and 2020. END was defined as an increase of ≥ 2 in the total National Institutes of Health Stroke Scale (NIHSS) score or ≥ 1 in the motor NIHSS score. IGV was calculated using the following formula: IGV (mL/h) = diffusion-weighted imaging volume (mL)/time to MRI (h). A total of 604 patients with SSI were evaluated. Multivariable logistic regression analysis showed that IGV remained significant after adjusting for confounders (aOR = 1.34, 95% CI 1.12-1.61). In a subgroup analysis based on the type of SSI, only patients with distal SSI showed an association between IGV and END (aOR = 1.64, 95% CI 1.24-2.16). In patients with proximal SSI, IGV did not show any statistical association with END. In conclusion, IGV was positively associated with END in patients with SSI. IGV should be interpreted differently in clinical settings depending on the location of the SSI lesion.

Abstract
Stroke constitutes a major cause of functional disability with increasing prevalence among adult individuals. Thus, it is of great importance for both clinicians and stroke survivors to be provided with a timely and accurate prognostication of functional outcome. A great number of biomarkers capable of yielding useful information regarding stroke patients' recovery propensity have been evaluated so far with leukoaraiosis being among them. Literature research of two databases (MEDLINE and Scopus) was conducted to identify all relevant studies published between 1 January 2012 and 25 June 2022 that dealt with the clinical utility of a current leukoaraiosis as a prognostic indicator following stroke. Only full-text articles published in English language were included. Forty-nine articles have been traced and are included in the present review. Our findings highlight the prognostic value of leukoaraiosis in an acute stroke setting. The assessment of leukoaraiosis with visual rating scales in CT/MRI imaging appears to be able to reliably provide important insight into the recovery potential of stroke survivors, thus significantly enhancing stroke management. Yielding additional information regarding both short- and long-term functional outcome, motor recovery capacity, hemorrhagic transformation, as well as early neurological deterioration following stroke, leukoaraiosis may serve as a valuable prognostic marker poststroke. Thus, leukoaraiosis represents a powerful prognostic tool, the clinical implementation of which is expected to significantly facilitate the individualized management of stroke patients.

Curr Neurovasc Res 2022; 19:232-239. [PMID: 35796446 DOI: 10.2174/1567202619666220707094342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 04/16/2022] [Accepted: 04/24/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Early neurological deterioration (END) often occurs during hospitalization in single small subcortical infarct (SSSI). While, symptoms on admission were rarely reported about its performance on predicting the risk of END. OBJECTIVES The objective of this study is to explore the relationship between symptoms on admission and END in SSSI. METHODS Patients with SSSI in the lenticulostriate artery (LSA) territory presenting within 72 hours of stroke onset were screened prospectively. Clinical characteristics, including symptoms on admission, laboratory tests and imaging findings, were collected. Based on the body regions involved including spherical face (SF), upper limb (UL) or lower limb (LL), symptoms on admission were classified into single spherical face (sSF) and any involvement of limbs (AL). END was defined as ≥2 points increase in total National Institutes of Health Stroke Scale (NIHSS) score or ≥ 1 point increase in motor score within 72 hours after admission. Multivariate logistic regression was used to analyze factors associated with END. RESULTS Out of 5,832 ischemic stroke patients in the database, 394 patients were finally enrolled in analysis. 65 patients (16.5%) developed END. Multivariable logistic regression revealed that symptoms with LL (OR 2.337, 95% CI 1.041-5.246), UL (OR 2.936, 95% CI 1.349-6.390) were both associated with END, while the involvement of SF (OR 0.447, 95% CI 0.249-0.804) showed the opposite result. Further analysis found that symptoms with AL (OR 3.958, 95% CI 1.355-11.565) showed a higher risk of END compared to sSF after adjustment. CONCLUSION Our results discovered that symptoms with AL carried a higher risk of END than those involving sSF in SSSI.

Abstract
Ischaemic stroke is characterized by high morbidity, high disability rate, high mortality and high recurrence rate, which can have a grave impact on the quality of life of the patients and consequently becomes an economic burden on their families and society. With the developments in imaging technology in recent years, patients with acute cerebral infarction are predominantly more likely to be diagnosed with leukoaraiosis (LA). LA is a common degenerative disease of the nervous system, which is related to cognitive decline, depression, abnormal gait, ischaemic stroke and atherosclerosis. The aetiology of LA is not clear and there is no gold standard for imaging assessment. Related studies have shown that LA has an adverse effect on the prognosis of cerebral infarction, but some experts have contrary beliefs. Hence, we undertook the present review of the literature on the mechanism and the effect of LA on the prognosis of patients with acute ischaemic stroke.

Abstract
BACKGROUND AND PURPOSE Patients with single subcortical infarctions (SSIs) have relatively a favorable prognosis, but they often experience early neurological deterioration (END). In this study, we compared the predictors for END in patients with SSI according to the location of the lesion. METHODS We included consecutive patients with SSIs within 72 hours of symptom onset presenting between 2010 and 2016. END was defined as an increase of ≥2 in the total National Institutes of Health Stroke Scale (NIHSS) score or ≥1 in the motor NIHSS score within the first 72 hours of admission. Along with the analysis of all patients with SSI, we also analyzed the predictors for END in proximal/distal SSI patients and anterior/posterior circulation SSI patients. RESULTS A total of 438 patients with SSI were evaluated. In multivariable analysis, initial NIHSS score (adjusted odds ratio, 1.36 [95% CI, 1.15-1.60]), pulsatility index (adjusted odds ratio, 1.25 [95% CI, 1.03-1.52]), parent artery disease (adjusted odds ratio, 2.14 [95% CI, 1.06-4.33]), and neutrophil-to-lymphocyte ratio (adjusted odds ratio, 1.24 [95% CI, 1.04-1.49]) were positively associated with END. In patients with proximal SSI, initial NIHSS score, pulsatility index, parent artery disease, and neutrophil-to-lymphocyte ratio showed positive associations with END. Meanwhile, no variable related to END was found in the distal SSI group. When we compared the predictors for END based on the involved vascular territory, higher initial NIHSS score and neutrophil-to-lymphocyte ratio were significantly associated with END in patients with anterior circulation SSIs. On the contrary, higher pulsatility index values and the presence of parent artery disease were independent predictors for END in patients with SSIs in the posterior circulation. CONCLUSIONS Initial NIHSS score, pulsatility index, parent artery disease, and neutrophil-to-lymphocyte ratio are associated with END in patients with SSIs. The frequency and predictors for END differ depending on the location of the SSI.

Abstract
BACKGROUND AND PURPOSE We aimed to evaluate factors associated with neurological worsening among patients with lacunar or non-lacunar infarction admitted within 3 hours and between 3 and 24 hours after stroke onset. METHODS All patients admitted to Haukeland university hospital between 2006 and 2016 with acute cerebral infarction on MRI and admission within 24 hours were included. Repeated National Institute of Health Stroke Scale (NIHSS) scoring was performed in all patients whenever possible. Neurological worsening during the hospital stay was defined as NIHSS score increase ≥3 compared to NIHSS score on admission. RESULTS In patients with lacunar infarction admitted within 3 hours of onset, neurological worsening was associated with low NIHSS score on admission, low body temperature, and leukoaraiosis, whereas only internal carotid artery stenosis or occlusion was associated with neurological worsening in non-lacunar infraction. For patients admitted 3-24 hours after onset, neurological worsening was associated with low body temperature, high systolic blood pressure, and short time from onset to admission in patients with lacunar infarction, whereas high systolic blood pressure, high NIHSS score on admission, middle cerebral artery occlusion, and high blood glucose were associated with neurological worsening in patients with non-lacunar infarction (all P < 0.05). CONCLUSIONS Lacunar infarctions with minor neurological deficits within 3 hours of stroke onset are at high risk of neurological worsening especially if concomitant low body temperature and leukoaraiosis.

Abstract
Chronic white matter structural injury is a risk factor for poor long-term outcomes after acute ischemic stroke (AIS). However, it is unclear how white matter structural injury predisposes to poor outcomes after AIS. To explore this question, in 42 AIS patients with moderate to severe white matter hyperintensity (WMH) burden, we characterized WMH and normal-appearing white matter (NAWM) diffusivity anisotropy metrics in the hemisphere contralateral to acute ischemia in relation to ischemic tissue and early functional outcomes. All patients underwent brain MRI with dynamic susceptibility contrast perfusion and diffusion tensor imaging within 12 h and at day 3-5 post stroke. Early neurological outcomes were measured as the change in NIH Stroke Scale score from admission to day 3-5 post stroke. Target mismatch profile, percent mismatch lost, infarct growth, and rates of good perfusion were measured to assess ischemic tissue outcomes. NAWM mean diffusivity was significantly lower in the group with early neurological improvement (ENI, 0.79 vs. 0.82 × 10-3, mm2/s; P = 0.02). In multivariable logistic regression, NAWM mean diffusivity was an independent radiographic predictor of ENI (β = - 17.6, P = 0.037). Median infarct growth was 118% (IQR 26.8-221.9%) despite good reperfusion being observed in 65.6% of the cohort. NAWM and WMH diffusivity metrics were not associated with target mismatch profile, percent mismatch lost, or infarct growth. Our results suggest that, in AIS patients, white matter structural integrity is associated with poor early neurological outcomes independent of ischemic tissue outcomes.

Abstract
BACKGROUND The patients of single small subcortical strokes (SS) commonly have neurological worsening with risk factors, and mechanisms remain unclear. Asymptomatic lacunes, white matter lesions, cerebral microbleeds, and enlarged perivascular spaces are MRI markers of cerebral small vessel disease (cSVD). Previous studies mostly explored the association between the neurological deterioration and presence of above markers separately. The relationship between progressive single small SS and the simultaneous presence of multiple markers of cSVD has not been fully identified. We aimed to investigate whether total burden of cSVD detected with MRI was associated with progressive small SS in this study. METHODS Patients with single small SS (2.0 cm in diameter) were prospectively recruited during January 2016 and May 2018. Progression was defined as worsening by ≥1 point in National Institutes Health Stroke Scale (NIHSS) motor score within 72 hr from onset. The presence and burden of cSVD were determined by brain MRI, producing a score between 0 and 4. Besides, the patients' characteristics, clinical data, medical treatments during hospitalization stay were collected and statistically analyzed. Associations with progression were tested with forward stepwise regression analyses. RESULTS Fifty-seven (35.6%) patients underwent progression. No significant difference was observed in the distribution of any single vascular risk factor and its related laboratory data among these patients. After adjustment for age, sex, NIHSS score at admission, and time from stroke to MRI in separate models, severe WMHs (OR = 4.892; 95% CI = 2.011-11.904, p = 0.016), moderate- and high-grade basal ganglia EPVS (OR = 2.970; 95% CI = 1.861-6.121, p = 0.009), and total cSVD score (OR = 3.359; 95% CI = 2.016-5.599, p = 0.010) were associated with progression. CONCLUSION This study demonstrated that total MRI cSVD burden was independently associated with progression after single small subcortical strokes.

Abstract
BACKGROUND Patients with intracerebral hemorrhage (ICH) have high disability and mortality. Leukoaraiosis refers to the diffuse abnormalities of white matter on neuroimaging, which has been suggested to be with poor outcome in patients with ICH. This meta-analysis was performed to summarize the current evidence on the prognostic significance of leukoaraiosis in ICH patients. METHODS Databases were searched for published studies about leukoaraiosis and prognosis in patients with ICH. Data from eligible studies were extracted. Odds ratios (ORs) and their 95% confidence intervals (CIs) from each study were combined with DerSimonian-Laird method and random effect model for quantitative analysis. Begg's funnel plot was adopted to assess the publication bias. RESULTS A total of nine studies with 4948 patients were finally included in this meta-analysis. Six studies reported functional outcome, two studies reported mortality, and another study reported both functional outcome and mortality. The meta-analysis showed that leukoaraiosis was significantly associated with worse functional outcome in patients with ICH (OR = 1.40, 95%CI 1.17-1.68, P < .001). In addition, leukoaraiosis was also significantly associated with higher mortality in patients with ICH (OR = 1.59, 95%CI 1.21-2.08, P = .001). CONCLUSIONS Leukoaraiosis is significantly associated with both worse functional outcome and higher mortality in patients with ICH. Leukoaraiosis can be a useful imaging marker for predicting outcome in patients with ICH.

Liu Y, Zhang M, Bao H, Zhang Z, Mei Y, Yun W, Zhou X. The efficacy of intravenous thrombolysis in acute ischemic stroke patients with white matter hyperintensity. Brain Behav 2018; 8:e01149. [PMID: 30378299 PMCID: PMC6305931 DOI: 10.1002/brb3.1149] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Accepted: 10/03/2018] [Indexed: 01/08/2023] Open
Abstract
OBJECTIVES We aimed to investigate effects of deep white matter hyperintensity (DWMH) and periventricular hyperintensity (PVH) on the efficacy of intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS). METHODS A total of 113 AIS patients with WMH were categorized into the PVH group and the DWMH group according to the lesion location, with the division of two subgroups based on whether or not they received IVT treatment: the thrombolysis group and the control group. Kaplan-Meier analysis was used for proportional hazards of recurrent stroke. Further, multivariate Cox regression analysis was employed. RESULTS Of total patients, there were 62 PVH patients and 51 DWMH patients: 27 of PVH patients and 22 of DWMH patients received IVT, and the remaining patients only received routine treatment. DWMH patients had a higher risk of END (36.4% vs. 11.1%; p = 0.034) and HT (22.7% vs. 3.7%; p = 0.038) than PVH patients in the thrombolysis group. Moreover, DWMH patients undergoing IVT also had a higher risk of END (36.4% vs. 10.3%; x2 = 5.050; p = 0.025) and HT (22.7% vs. 3.4%; x2 = 4.664; p = 0.031) than DWMH patients without IVT. Again, PVH patients had a higher rate of recurrent stroke (20.0% vs. 3.4%; p = 0.034) than DWMH patients in the control group after 90-day follow-up. Kaplan-Meier analysis showed a significant difference in cumulative probability of no major endpoint events (p = 0.039). Further, multivariate Cox regression revealed that PVH is an independent risk factor for stroke recurrence in AIS patients after adjusting confounding factors. CONCLUSIONS The location of WMH is closely associated with the efficacy of IVT in AIS patients.

Abstract
Leukoaraiosis, a radiographic marker of cerebral small vessel disease detected on T2-weighted brain magnetic resonance imaging (MRI) as white matter hyperintensity (WMH), is a key contributor to the risk and severity of acute cerebral ischemia. Prior investigations have emphasized the pathophysiology of WMH development and progression; however, more recently, an association between WMH burden and functional outcomes after stroke has emerged. There is growing evidence that WMH represents macroscopic injury to the white matter and that the extent of WMH burden on MRI influences functional recovery in multiple domains following acute ischemic stroke (AIS). In this review, we discuss the current understanding of WMH pathogenesis and its impact on AIS and functional recovery.

Association between Leukoaraiosis and Poor Outcome is not due to Reperfusion Inefficiency after Intravenous Thrombolysis. Transl Stroke Res 2016; 7:439-45. [PMID: 27256491 DOI: 10.1007/s12975-016-0473-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Revised: 05/16/2016] [Accepted: 05/18/2016] [Indexed: 10/21/2022]
Abstract
Leukoaraiosis (LA) is associated with structural and functional cerebrovascular impairment, which may compromise the capacity of ischemic tissue to maximize reperfusion after intravenous thrombolysis (IVT). We aimed to determine whether severe LA is correlated with reperfusion inefficiency, which contributes to infarct growth and poor functional outcome. We analyzed data from our consecutive acute ischemic stroke (AIS) patients who had acquired baseline and 24-h follow-up diffusion- and perfusion-weighted imaging. Reperfusion was defined as reduction of ≥70 % of hypoperfusion lesion at 24 h from baseline. Severe LA was defined as Fazekas score 2 or 3 on FLAIR images. We investigated the relationship between severity of LA and reperfusion status. Multivariate statistical analysis was carried out for modeling the independent predictors of reperfusion, infarct growth, and functional outcome. Finally, 79 patients were included, among them 30 (37.97 %) had severe LA. Reperfusion was observed in 41 (51.89 %) patients, the proportion of reperfusion was very similar in patients with and without severe LA (53.33 vs 51.02 %, p = 1.000). Large artery occlusion was the only independent unfavorable predictor for reperfusion (OR = 0.202, 95 % confidence interval, 0.060-0.673; p = 0.014). Multiple linear regression analysis revealed that severe LA was independently associated with infarct growth (standardized coefficients = 0.191, p = 0.040). Severe LA was also an independent predictor of poor outcome (mRS ≥ 3) (OR = 4.004, 95 % confidence interval, 1.267-12.656, p = 0.018) after adjusting for reperfusion and baseline severity of stroke. Severe LA was associated with infarct growth and poor outcome independent of reperfusion status, which may expand the notion that LA contributes the intrinsic vulnerability of brain tissue to acute ischemic insults. The burden of LA may not serve as an imaging indicator of reperfusion inefficiency after IVT for AIS patients.

Abstract
BACKGROUND AND PURPOSE Dilated Virchow-Robin spaces (dVRSs) were regarded as a phenotype of cerebral small-vessel disease (SVD). However, the clinical correlations of dVRS were still unclear. In this study, we aimed to investigate the topography and clinical correlations of dVRS in first-ever lacunar stroke patients. METHODS Patients with first-ever lacunar stroke were recruited and had magnetic resonance scans to identify the presence and degree of dVRS in the basal ganglia (BG-dVRS), dVRS in the central semiovale (CSO-dVRS), leukoaraiosis, and silent brain infarction (SBI). The neurological deficits after stroke onset and functional outcome after 1 year were evaluated using National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale, respectively. Clinical and radiological features were compared between patients with high and low degrees of dVRS, and between patients with favorable and unfavorable outcomes. Logistic regression models were constructed to identify the risk factors of unfavorable outcome. RESULTS The NIHSS scores were not statistically different between patients with high and low degrees of dVRS. More patients with high degrees of BG-dVRS had unfavorable outcomes than those with low degrees of BG-dVRS. Logistic regression showed that the degrees of BG-dVRS, leukoaraiosis, and SBIs were not independent risk factors for the unfavorable outcome, whereas the total burden of SVD was an independent risk factor for the unfavorable outcome. CONCLUSION The degrees of either BG-dVRS or CSO-dVRS were not associated with the severity of first lacunar stroke. BG-dVRS was related to the unfavorable 1-year outcome. This association might be based on the total severity of SVD.

Abstract
OBJECTIVES Early neurological worsening is common in minor subcortical strokes (SS) and may lead to a poor outcome. We aimed to describe clinical and imaging features associated with progression. MATERIAL AND METHODS Consecutive patients with SS were divided into progressive and non-progressive. Progression was defined as an increase of NIHSS motor score ≥ 1 point within 72 h from onset. Vascular risk factors and imaging features (vascular territory, size and number of slices in which the lesion was visible, the presence of leukoaraiosis) were compared in the two groups. We investigated potential independent determinants of progression using stepwise logistic regression. RESULTS Thirty of 94 patients (31.9%) underwent progression. The distribution of vascular risk factors did not differ significantly between the two groups. Increasing number of risk factors was associated with a higher risk of progression (OR 2.2; 95% CI 1.1-4.5). Patients who progressed were more likely to have a lesion ≥ 15 mm in diameter (P = 0.004) or a lesion visible ≥ 3 slices (P = 0.007). After logistic regression stepwise adjustment for all the considered potential determinants, diameter ≥ 15 mm and severe leukoaraiosis proved to be independently associated with neurological worsening (OR = 6.3, 95% CI 2.0-19.6 and OR = 5.9, 95% CI 1.3-25.7, respectively). CONCLUSION In a series of consecutive SS, early neurological worsening was associated with a high vascular risk profile, a larger infarct size and the presence of severe leukoaraiosis. Based on the knowledge that extensive microvascular changes are a feature of severe leukoaraiosis, we hypothesize that stroke progression could be promoted through an impaired compensatory flow in the penumbral area.
