ABSTRACT

Objective:To investigate the value of net water uptake (NWU) for predicting early neurological improvement (ENI) after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke.Methods:A case-control study. A total of 132 patients (80 men, 52 women, median age 68 years) with acute anterior circulation large vessel occlusive stroke receiving endovascular treatment were retrospectively analyzed at Jinling Hospital from October 2014 to September 2019. Patients were divided into two groups based on the occurrence of ENI, which was defined as either an improvement of NIHSS score of ≥4 points, or an NIHSS score of 0 or 1 at 24 hours after endovascular treatment. The rank sum test, Chi square test, and other methods were used to compare differences in baseline characteristics between the two groups. Logistic regression analysis was used to investigate independent predictors of postoperative ENI. Receiver operating characteristic curve analysis used to assess the capacity of NWU to predict ENI.Results:Of the 132 patients in the study, ENI occurred in 47 and did not occur in 85. In multivariate logistic regression analysis age [odds ratio ( OR)=0.940, 95% confidence interval ( CI) 0.903-0.979, P=0.003], time from stroke onset to puncture ( OR=0.995, 95% CI 0.991-0.999, P=0.025), time from puncture to recanalization/end of operation ( OR=0.985, 95% CI 0.974-0.996, P=0.007), NWU ( OR=0.762, 95% CI 0.620-0.937, P=0.010), and mTICI ( OR=1.644, 95% CI 1.043-2.590, P=0.032) were predictive factors for ENI. Receiver operating characteristic curve analysis indicated that NWU could effectively predict ENI (area under the curve=0.642, 95% CI 0.543-0.741, P=0.007), and prediction accuracy was improved when it was combined with other clinical parameters. Conclusion:NWU is an independent predictor of ENI in patients with acute anterior circulation large vessel occlusive stroke undergoing endovascular treatment.

ABSTRACT

Objective:To investigate the effect of insular involvement on the outcomes of patients with acute anterior circulation ischemic stroke.Methods:Patients with acute anterior circulation ischemic stroke admitted to the Department of Neurology, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to December 2020 were retrospectively included. Demographic data, vascular risk factors, clinical and laboratory data, as well as treatment and outcomes were collected. Firstly, the correlation between the insular involvement and the outcomes was investigated, and then the bootstrap method was used to clarify the mediating role of infarct volume between the insular involvement and the poor outcomes.Results:A total of 450 patients with acute anterior circulation ischemic stroke were enrolled, among whom 79 cases (17.6%) had insular involvement and 41 (9.1%) had left insular involvement. There were 111 (24.7%) with poor outcomes, including 5 (1.1%) died. Compared to the non-insular involvement group, the insular involvement group had a higher proportion of patients with atrial fibrillation, shorter onset to door time, higher neutrophil-to-lymphocyte ratio (NLR), higher National Institutes of Health Stroke Scale (NIHSS) score at admission, larger infarct volume, and higher proportion of patients with poor outcomes (all P<0.05). In addition, patients with left insular involvement were younger than those with right insular involvement, had a higher baseline NIHSS score, a lower proportion of patients with minor stroke (NIHSS score ≤8), and had a longer onset to door time (all P<0.05). Compared to the good outcome group, the poor outcome group was older, with a higher proportion of female patients, higher systolic blood pressure, blood glucose, NLR, and NIHSS scores at admission, larger infarct volume, and a higher proportion of patients with insular involvement (all P<0.05). Mediation analysis suggested that the mediating effect of infarct volume between the insular involvement and the poor outcomes was significant (95% confidence interval 0.033-0.230; P=0.008). Conclusions:insular involvement in patients with acute anterior circulation ischemic stroke is associated with the poor outcomes, and this association may be mediated by infarct volume. Patients with left insular involvement may have more severe symptoms than those with right insular involvement, but there is no significant difference in the outcomes.

ABSTRACT

Objective:To explore the prognostic prediction value of quantitative digital subtraction angiography (DSA) parameters in patients with acute anterior circulation ischemic stroke undergoing mechanical thrombectomy, and whether the clinical values vary by stroke etiology.Methods:This study was a post hoc analysis of the Multicenter Prospective Captor Trial. Patients with acute anterior circulation large-vessel occlusion and successful recanalization from April 2018 to July 2019 were screened. Post-processing analysis was performed on the DSA imaging sequence after recanalization, and 4 regions of interest (ROI) were selected in the target vessel: ROI1 (the proximal of the internal carotid artery-C2 segment), ROI2 (the starting point of the internal carotid artery-C7 segment), ROI3 (the end of the middle cerebral artery-M1 segment), and ROI4 (the end of the middle cerebral artery-M2 segment). Time to peak (TTP) was defined as the time at contrast concentration of selected ROI reached its maximum. Relative TTP (rTTP) was calculated by subtracting the TTP of ROI1 from the TTP of distalis ROIs. Successful recanalization was defined as modified Thrombolysis In Cerebral Infarction (mTICI) grade≥2b. Favorable outcomes at 3 months were defined as the modified Rankin Scale score≤2. According to the modified Rankin Scale score, the patients were divided into good prognosis group and poor prognosis group. The differences in clinical characteristics, postoperative hemodynamic parameters, and other data were compared between patients with good and poor prognoses. Univariate and multivariate Logistic regression was used to analyze factors related to a good prognosis. Finally, the prognostic prediction value of hemodynamic parameters was analyzed in patients with different Trial of Org10172 in Acute Stroke Treatment etiological classifications.Results:A total of 245 patients were collected, of which 161 patients [age 69 (60, 76) years, 92 (57.1%) male] were finally included in the analysis, including 36 cases of large artery atherosclerosis (LAA) stroke, 76 cases of cardiogenic embolism (CE), and 49 cases of other causes of stroke. Seventy-one (44.1%) patients had favorable outcomes at 3 months. The post-operative hemodynamic analysis indicated that patients with favorable outcomes ( n=71) had a higher proportion of mTICI grade 3 [54/71 (76.1%) vs 41/90 (45.6%),χ 2=15.26, P<0.001] and lower rTTP 31 [means TTP ROI3-TTP ROI1;0.33 (0.23, 0.54) s vs 0.47 (0.31, 0.65) s, Z=-2.71, P=0.007] than patients with unfavorable outcomes ( n=90). The mTICI score and rTTP 31 were respectively included in multivariate Logistic regression models. It was shown that mTICI grade 3 (adjusted OR=5.97, 95% CI 2.49-14.27, P<0.001) and rTTP 31 (adjusted OR=0.24, 95% CI 0.06-0.99, P=0.048) were significantly associated with favorable outcomes, and the area under the receiver operating characteristic curve of the models had no statistically significant difference ( P=0.170). Subgroup analysis showed that rTTP 31 was significantly associated with the prognosis of patients with LAA stroke ( OR=0, 95% CI 0-0.25, P=0.014), while mTICI grade was associated with the prognosis of patients with CE ( OR=3.91, 95% CI 1.40-10.91, P=0.009) and other etiologies ( OR=7.35, 95% CI 1.92-28.14, P=0.004). Conclusions:In patients with acute anterior circulation ischemic stroke and successful recanalization, both mTICI score and rTTP 31 had significant predictive value for favorable outcomes at 3 months. Moreover, rTTP 31 was significantly associated with the prognosis of patients with LAA stroke, while mTICI score was significantly related to the prognosis of patients with CE and other causes of stroke.

ABSTRACT

Objective:To investigate the correlation between the lipocalin-2 (LCN-2) level and white matter hyperintensities (WMHs) in patients with ischemic stroke.Methods:Consecutive patients with ischemic stroke admitted to the Department of Neurology, Jinling Hospital, Medical School of Nanjing University from September 2021 to November 2021 and whose duration from onset to hospitalization <14 d were prospectively enrolled. Enzyme-linked immunosorbent assay was used to detect the serum LCN-2. Fazekas scale was used to assess the severity of periventricular and subcortical WMHs. A total WMHs score ≥3 was defined as severe WMHs. Multivariate logistic regression analysis was used to determine the correlation between serum LCN-2 level and WMHs. Results:A total of 179 patients were enrolled, including 122 males (68.2%), aged 64.7±11.6 years. The median serum LCN-2 level was 387.1 g/L, and 86 patients (48.0%) had severe WMHs. Serum LCN-2 in the severe WMH group was significantly higher than that in the non-severe WMH group (505.3±342.4 g/L vs. 367.8±224.5 g/L; t=3.110, P=0.002). Multivariable logistic regression analysis showed that after adjusting for the relevant confounding factors, there was a significant correlation between higher serum LCN-2 and severe WMHs (odds ratio 2.32, 95% confidence interval 1.17-4.63; P=0.017) and higher total WMHs score (odds ratio 1.62, 95% confidence interval 1.12-2.35; P=0.011). Conclusion:Higher serum LCN-2 level is associated with severe WMHs in patients with ischemic stroke.

ABSTRACT

Intracranial artery stenosis is the main cause of ischemic stroke in China. Because of the high recurrence rate of stroke in these patients, the selected patients may benefit from interventional therapy. Therefore, risk stratification and evaluation of intracranial artery stenosis are helpful to determine the clinical treatment plan. High resolution magnetic resonance imaging can clearly show the characteristics of intracranial vascular wall, which is helpful to comprehensively evaluate intracranial vessels. This article reviews the characteristics of vulnerable plaque of intracranial atherosclerosis, the pathogenesis of stroke and the clinical application of high-resolution magnetic resonance imaging in intracranial artery stenosis.

ABSTRACT

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare, low-grade neoplasm, which is newly categorized into the neuronal and mixed neuro-glial tumor in 2016. The most characteristic imaging findings are diffuse leptomeningeal thickening and enhancement with multiple minor cysts. This article described a case with DLGNT mimicking meningitis, whose cystic lesions were not obvious, with swollen multiple lobes cortex, gyri form cortical calcification and enhanced meninges. Meningeal irritation sign repeated attacks and the clinical symptoms gradually improved after steroid pulse therapy. The biopsy and immunohistochemistry staining were diagnosed as DLGNT. The imaging features and clinical data of this case were analyzed to improve the understanding of the disease in clinical practice.

ABSTRACT

Objective:To investigate the correlation between obstructive sleep apnea (OSA) and triglyceride-glucose (TyG) indexin patients with ischemic stroke.Methods:Patients with ischemic stroke underwent sleep breathing monitoring in Nanjing Stroke Registry Program from August 2020 to August 2021 were retrospectively enrolled. According to apnea-hypopnea index (AHI), the patients were divided into no/mild OSA group (AHI≤15 events/h) and moderate to severe OSA group (AHI>15 events/h). The TyG index was calculated according to triglycerides and fasting blood glucose, and the patients were grouped by quartile. The relationship between moderate to severe OSA and TyG index was determined by ordinal multinomial logistic regression analysis. Pearson correlation analysis was used to evaluate the correlation between TyG index and AHI. Results:A total of 155 patients with ischemic stroke were enrolled in the study, including 66 patients in the no/mild OSA group, 89 in the moderate to severe OSA group; 39 in the Q1 group (TyG index ≤8.46), 39 in the Q2 group (TyG index 8.47-8.78), 39 in the Q3 group (TyG index 8.79-9.17), and 38 in the Q4 group (TyG index >9.17). Ordinal multinomial logistic regression analysis showed that after adjusting for potential confounding factors, higher fasting blood glucose (odds ratio 2.370, 95% confidence interval 1.745-3.222; P<0.001) and moderate to severe OSA (odds ratio 2.377, 95% confidence interval 1.217-4.646; P=0.011) had significant independent positive correlation with TyG index. Pearson correlation analysis showed that AHI was positively correlated with the TyG index in patients with ischemic stroke ( r=0.209, P=0.011). Conclusion:OSA is independently correlated with TyG index in patients with ischemic stroke.

ABSTRACT

Objective:To validate the predictive function of Field Assessment Stroke Triage for Emergency Destination (FAST-ED) score on large vessel occlusion (LVO) in Chinese population.Methods:The information about the patients who had the disease onset within 24 hours, were treated in the Emergency Department of Jinling Hospital, and diagnosed as ‘acute ischemic stroke’ was collected. Via the emergent brain computed tomography angiography or digital subtraction angiography, the patients were divided into LVO group and non-LVO group. The scores of FAST-ED were calculated according to the National Institutes of Health Stroke Scale (NIHSS) scores and compared with Rapid Arterial oCclusion Evaluation (RACE), 3-item Stroke Scale (3I-SS), Cincinnati Stroke Triage Assessment Tool (C-STAT), and Prehospital Acute Stroke Scale (PASS) scores. Moreover, the patients were further divided into anterior and posterior circulation lesion groups to explore whether the FAST-ED scale can differ the anterior or posterior circulation effectively.Results:Three hundred and eighty-one patients were eventually included, among whom 284 were diagnosed as LVO, and 97 were diagnosed as non-LVO. Receiver operating characteristic curves showed that cut-off value of 4 optimized the scale (sensitivity: 0.76, specificity: 0.69, area under the curve: 0.78). The area under the curve of FAST-ED score(0.78) showed no statistically significant difference with NIHSS (0.79), RACE (0.77), 3I-SS (0.78) and C-STAT scores (0.75), and exhibited statistically significant difference with PASS score (0.74; 95% CI 0.69-0.78, P=0.01). FAST-ED score showed no statistically significant difference in predicting anterior and posterior circulation lesions. Conclusions:FAST-ED score can predict LVO in a rather accurate manner. It can predict anterior and posterior circulation lesions with similar effectiveness. So FAST-ED is able to be a prehospital screening tool and make assistance to the prehospital treatment.

ABSTRACT

Objective:To evaluate the characteristics of carotid plaque and the immediate outcomes after carotid artery stenting (CAS) in diabetic and non-diabetic patients by optical coherence tomography (OCT).Methods:Patients underwent CAS and OCT before and after operation in the Department of Neurology, Jinling Hospital from January 2014 to March 2019 were enrolled retrospectively. The clinical features, the characteristics of carotid plaque on OCT and the immediate outcomes after CAS were compared between diabetic group and non-diabetic group. The risk factors of stent malapposition were analyzed.Results:A total of 46 patients were enrolled. Their age was 64.02±8.32 years and 41 were males (89.1%). There were 20 patients (43.5%) in the diabetes group and 26 (56.5%) in the non-diabetes group. The proportions of atherosclerotic plaque with thin fibrous cap (40.0% vs. 7.7%; χ2=5.166, P=0.023), plaque rupture (55.0% vs. 23.1%; χ2=4.945, P=0.026) and macrophage infiltration (60.0% vs. 30.8%; χ2=3.930, P=0.047) in the diabetic group were significantly higher than those in the non-diabetic group. Multivariate logistic regression analysis showed that older age (odds ratio [ OR] 1.208, 95% confidence interval [ CI] 1.033-1.413; P=0.018), coronary heart disease ( OR 15.953, 95% CI 1.142-222.952; P=0.040), alcohol consumption ( OR 6.192, 95% CI 1.098-34.923; P=0.039) and lower systolic blood pressure ( OR 0.944, 95% CI 0.894-0.997; P=0.037) were independently associated with stent malaposition. Conclusion:Compared with the non-diabetic patients, carotid plaque in diabetic patients may be more unstable. Older age, coronary heart disease, alcohol consumption and lower systolic blood pressure were associated with stent malaposition after carotid stenting. OCT can reveal the characteristics of carotid plaque and the immediate outcomes after CAS, which can provide strong evidence for treatment decision.

ABSTRACT

Objective:To explore the value of intravascular optical coherence tomography (OCT) in evaluating carotid atherosclerotic stenosis, and compare the morphological characteristics of symptomatic and asymptomatic carotid atherosclerotic plaques.Methods:Patients diagnosed as carotid atherosclerotic stenosis and performed OCT in the Department of Neurology, Jinling Hospital, Medical School of Nanjing University from January 2017 to November 2019 were enrolled retrospectively. Digital subtraction angiography (DSA) and OCT were used to determine the degree of stenosis of the diseased vessels, and the plaque characteristics observed by OCT were recorded. Symptomatic carotid atherosclerotic stenosis is defined as a history of transient ischemic attack, amaurosis fugax, or stroke related to the blood supply area of the diseased vessel within 6 months before the carotid artery examination. The baseline clinical and imaging data of the symptomatic group and the asymptomatic group were compared. Multivariate logistic regression analysis was used to determine the independent risk factors for symptomatic carotid atherosclerotic stenosis. Results:A total of 56 patients were enrolled. DSA and OCT had good consistency in carotid artery diameter measurement ( r=0.93, P<0.001). When the OCT technique was used to evaluate the plaque properties, the consistency of inter-observer ( κ=0.96, P<0.001) and intra-observer ( κ=0.96, P<0.001) was higher. The proportions of patients with type Ⅵ plaque (66.7% vs. 34.5%; P=0.016) and macrophage infiltration (51.9% vs. 24.1%; P=0.032) in the symptomatic group were significantly higher than those in the asymptomatic group, while the proportion of patients with fibrotic plaque was significantly lower than that in the asymptomatic group (40.7% vs. 69.0%; P=0.034). Multivariate logistic regression analysis suggested that type Ⅵ plaques (odds ratio 13.798, 95% confidence interval 1.38-137.675; P=0.025) and macrophage infiltration (odds ratio 5.856, 95% confidence interval 1.405-24.406; P=0.015) were the independent risk factors for symptomatic carotid atherosclerotic stenosis. Conclusions:OCT can be used to evaluate the degree of vascular stenosis and plaque characteristics in patients with carotid atherosclerotic stenosis. The detection rate of complex plaques in patients with symptomatic carotid atherosclerotic stenosis is significantly higher. Type Ⅵ plaque and macrophage infiltration are the independent risk factors for symptomatic carotid atherosclerotic stenosis.

ABSTRACT

Objective To investigate the effect of butylphthalide and sodium chloride injection on patients who received endovascular treatment for acute anterior circulation large vessel occlusive stroke.Methods A total of 173 patients were identified from February 2015 to December 2017 in the Department of Neurology of Jingling Hospital in this retrospective observational study.Propensity score-matching analysis was performed to balance differences in baseline characteristics between patients who received butylphthalide injection (butylphthalide group) and those who did not (control group).The modified Rankin Scale scores at 90 days were compared between the butylphthalide and control groups.Results A total of 144 patients who received endovascular treatment for acute anterior circulation large vessel occlusive stroke were finally analyzed,54 cases in the butylphthalide group and 90 cases in the control group.The proportion of good functional outcome at 90 days in the butylphthalide group was higher than that in the control group (63.0% (34/54) vs 44.4% (40/90);x2=4.633,P=0.031).Thirty-six pairs were matched successfully by the propensity score matching,36 patients in the butylphthalide group and 36 in the control group.There was no statistically significant difference in the 90-day functional outcome between the two groups (66.7% (24/36) vs 44.4% (16/36);x2=3.600,P=0.058).One hundred and fifteen patients were recanalized,47 cases in the butylphthalide group and 68 cases in the control group,and after the propensity score matching,30 pairs were analyzed.The proportion of good functional outcome at 90 days in the butylphthalide group was higher than that in the control group (73.3% (22/30) vs 46.7% (14/30);x2=4.444,P=0.035).Conclusion After propensity score-matching,butylphthalide and sodium chloride injection could improve 90-day functional outcome in patients with acute anterior circulation large vessel occlusive stroke and obtained recanalization by endovascular treatment while could not before propensity score-matching.

ABSTRACT

Objective To evaluate the value of stroke prognostication using age and National Institute of Health Stroke Scale index (SPAN) for outcome after early endovascular treatment for anterior circulation large vessel occlusion.Methods The patients who underwent early endovascular treatment were prospectively,sequentially collected in Yijishan Hospital of Wannan Medical College from December 2014 to September 2017 and Jinling Hospital from March 2014 to March 2017.Individuals whose age in years plus NIHSS score was greater than or equal to 100 were designated as SPAN-100-positive patients,while those with a score less than 100 were designated as SPAN-100-negative patients.We compared the baseline data and perioperative data between the two groups.The 90 days modified Rankin Scale score≤2 was regarded as favorable outcome.Single factor and multivariable Logistic regression analyses were used to determine the association between SPAN-100 and outcomes.Results One hundred and ninety patients were enrolled,20 (10.5%) of which were SPAN-100 positive,and 170(89.5%) were SPAN-100 negative.There were no significant differences between the two groups on postoperative intracerebral hemorrhage and 90 days mortality.Ninety days independence rates were higher in SPAN-100-negative patients (77/170,45.3%) than in SPAN-100 positive patients (4/20,20.0%;x2 =4.681,P =0.030).Multi-factor Logistic regression analysis showed that the higher preoperation systolic pressure (OR =1.030,95% CI 1.008-1.052,P =0.007),the lower Alberta Stroke Program Early CT Score (OR =1.609,95% CI 1.056-2.453,P =0.027) and poor collateral circulation(OR =5.714,95% CI 1.668-19.570,P =0.006) were the independent risk factors of outcomes.Conclusion SPAN-100 is not an independent predictor of favorable outcome after adjusting for factors of outcomes in patients with anterior circulation large vessel occlusion.

ABSTRACT

As an emerging intravascular imaging technology, intravascular optical coherence tomography (OCT) has been recognized for its clinical application value in the continuous exploration of the past decade. With its high resolution, OCT can clearly display the subtle morphological features of arterial stenosis lesions, help select treatment options, guide stent placement, and evaluate stent-vessel relationship and neo-intimal coverage after stent implantation for timely detecting early and late complications after stent placement. In recent years, a series of studies have also explored the value of OCT in the evaluation of cerebral angiography and intracranial and extracranial artery stent placement. We made a review of this topic.

Objective To investigate the differential effect of neutrophil to lymphocyte ratio (NLR) at admission on large artery atherosclerosis (LAA) and small vessel occlusion (SVO) in patients with minor stroke.Methods Patients with first-ever acute ischemic stroke registered in Nanjing Stroke Registration System were enrolled retrospectively.Minor stroke was defined as the National Institutes of Health Stroke Scale (NIHSS) score ≤3.Binary logistic regression was used to evaluate the independent relationship between NLR and LAA.Results A total of 417 patients with minor stroke were included,of which 242 were in a LAA group and 175 were in a SVO group.Univariate analysis showed that there were significant differences in leukocyte count,neutrophil count,lymphocyte count,NLR,glycosylated hemoglobin,highdensity lipoprotein cholesterol,onset to treatment time,and onset to NLR detection time between the patients of the LAA group and the SVO group (all P >0.05).Binary logistic regression analysis suggested that after adjusting for sex and high-density lipoprotein cholesterol,NLR (with the highest quartile as a reference,the first quartile:odds ratio [OR] 0.207,95% confidence interval [CI]0.089-0.482;P > 0.001;the second quartile:OR 0.277,95% CI 0.122-0.625,P=0.002;the third quartile:OR 0.456,95% CI 0.197-1.057;P =0.067),onset to NLR detection time (OR 1.216,95% CI 1.038-1.424;P =0.015),and glycosylated hemoglobin (OR 1.414,95% CI 1.142-0.751;P=0.002) were independently associated with LAA.The area under the ROC curve of NLR predicting the LAA was 0.611 in patients admitted within 7 d after onset,and was 0.673 in patients admitted within 24 h after onset.Conclusions The increased NLR was independently associated with the LAA in patients with minor stroke.Early NLR value may have higher predictive value for LAA.
