Development and validation of a clinical prediction model for ischemic stroke recurrence after successful stent implantation in symptomatic intracranial atherosclerotic stenosis. J Clin Neurosci 2024; 123:137-147. [PMID: 38574685 DOI: 10.1016/j.jocn.2024.03.028] [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: 12/04/2023] [Revised: 03/18/2024] [Accepted: 03/28/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE This study aimed to analyze the risk factors for recurrent ischemic stroke in patients with symptomatic intracranial atherosclerotic stenosis (ICAS) who underwent successful stent placement and to establish a nomogram prediction model. METHODS We utilized data from a prospective collection of 430 consecutive patients at Jining NO.1 People's Hospital from November 2021 to November 2022, conducting further analysis on the subset of 400 patients who met the inclusion criteria. They were further divided into training (n=321) and validation (n=79) groups. In the training group, we used univariate and multivariate COX regression to find independent risk factors for recurrent stroke and then created a nomogram. The assessment of the nomogram's discrimination and calibration was performed through the examination of various measures including the Consistency index (C-index), the area under the receiver operating characteristic (ROC) curves (AUC), and the calibration plots. Decision curve analysis (DCA) was used to evaluate the clinical utility of the nomogram by quantifying the net benefit to the patient under different threshold probabilities. RESULTS The nomogram for predicting recurrent ischemic stroke in symptomatic ICAS patients after stent placement utilizes six variables: coronary heart disease (CHD), smoking, multiple ICAS, systolic blood pressure (SBP), in-stent restenosis (ISR), and fasting plasma glucose. The C-index (0.884 for the training cohort and 0.87 for the validation cohort) and the time-dependent AUC (>0.7) indicated satisfactory discriminative ability of the nomogram. Furthermore, DCA indicated a clinical net benefit from the nomogram. CONCLUSIONS The predictive model constructed includes six predictive factors: CHD, smoking, multiple ICAS, SBP, ISR and fasting blood glucose. The model demonstrates good predictive ability and can be utilized to predict ischemic stroke recurrence in patients with symptomatic ICAS after successful stent placement.

Abstract
BACKGROUND Middle cerebral artery (MCA) occlusion is extremely common, especially unilateral artery, which can result in a significant incidence of cerebral infarction. OBJECTIVE To assess the value of whole-brain computed tomography perfusion (CTP) imaging combined with dynamic CT angiography (dCTA) in the evaluation of pial collateral circulation in patients with MCA occlusion. METHODS Whole-brain CTP and dCTA images were acquired in 58 patients with unilateral MCA occlusion. All patients were divided into three groups according to the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral score (by CTA). The CTP parameters were analysed, including relative cerebral blood flow (rCBF), relative cerebral blood volume (rCBV), relative mean transit time (rMTT), and relative time to peak (rTTP). Patients were followed up with the modified Rankin scale (mRS). All cases in this study were confirmed by DSA. RESULTS The CTP parameters of the MCA blood supply area on the affected side of patients with different degrees of stenosis were significantly different from those on the unaffected side. There are significant differences in the CTP parameters and openings of the Willis circle in patients with different degrees of stenosis. Significant differences were found in the number of patients with good prognosis. CONCLUSIONS Whole-brain CT perfusion combined with dynamic CTA can structurally and functionally evaluate the establishment of pial collateral circulation and its effect on cerebral hemodynamic changes.

Abstract
BACKGROUND Patients with multiple intracranial atherosclerotic stenoses often present with haemodynamic instability in two remote regions without a reciprocal vascular network. In this situation, revascularisation to each region may be required. METHODS In this report, two patients who had coexisting unilateral middle cerebral artery (MCA) and contralateral anterior cerebral artery (ACA) territory ischemia were treated by using ipsilateral superficial temporal artery (STA)-radial artery graft (RAG)-contralateral A3 bypass and ipsilateral STA-MCA bypass in one stage. RESULTS Postoperatively, the bypass conduit was well established and the patients' haemodynamic instability was improved. CONCLUSION In patients with severe haemodynamic instability in the remote unilateral MCA and contralateral ACA regions, as in our two cases, ipsilateral STA-MCA and ipsilateral STA-RAG-contralateral A3 bypasses in one stage can be a treatment option.

Abstract
INTRODUCTION Large artery intracranial occlusive disease including middle cerebral artery (MCA) is a major contributor to the incidence of stroke in China. The data on the prognosis of symptomatic atherosclerotic MCA occlusions (MCAO) are limited. We aimed to investigate the related factors of unfavorable outcomes in patients with stroke associated with MCAO. MATERIAL AND METHODS A total of 119 patients with MCAO symptom were enrolled in this retrospective longitudinal cohort study. All patients met inclusion criteria of cerebral angiography by CT angiography or magnetic resonance angiography. Stroke severity was assessed on admission using the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). RESULTS We showed an average follow-up time of 46.8 months, within which 20 (19.6%) cases died and 14 (13.7%) cases had stroke recurrence. Using mRS as an evaluation index, the patients were divided into an unfavourable outcome group (mRS > 2, 48 cases) and a favourable outcome group (mRS ≤ 2, 54 cases). Logistic regression analysis suggests that age and NIHSS score were independent risk factors for a poor outcome value. Coexisting other cerebral vascular occlusion was an independent risk factor for stroke recurrence. Age was an independent risk factor for death. CONCLUSIONS The prognosis of patients with MCAO was generally optimistic, with higher survival rate and longer survival time. As compared, elder age and higher NIHSS score both tend to be associated with worse prognosis of survival. MCAO patients with other extracranial or intracranial vascular occlusion have higher risk of recurrent stroke. Death rate increases with age among the MCAO patients.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) has shown to be associated with carotid plaque vulnerability. However, the impact of T2DM on intracranial artery atherosclerosis is not well-understood. PURPOSE To evaluate the association of diabetes and glycemic control with intracranial atherosclerotic plaque characteristics identified by three-dimensional contrast enhanced MR vessel wall imaging in patients after acute ischemic stroke. STUDY TYPE Prospective. POPULATION Two hundred and eighty-eight symptomatic patients with acute ischemic stroke due to intracranial atherosclerotic plaque. FIELD STRENGTH/SEQUENCE T1 WI volume isotropic turbo spin-echo acquisition sequence at 3.0 T. ASSESSMENT Clinical profiles, blood biomarkers, the number of intracranial plaques, plaque enhanced score, and the features (location, luminal stenotic rate, intraplaque hemorrhage, length, burden, enhancement grade, and ratio) of culprit plaque (defined as the most stenotic lesion ipsilateral to the ischemic event) and nonculprit plaque were analyzed by three radiologists. STATISTICAL TESTS Analysis of variance (ANOVA), Shapiro-Wilk normality test, Levene's test, ANOVA with Bonferroni post-hoc test, Kruskal Wallis H test with subsequent pairwise comparisons, chi-square with Bonferroni post-hoc test, generalized linear regression, Pearson correlation test, Kendall's W and intra-class correlation coefficient. RESULTS Two hundred and twenty-five participants (age 60 ± 10 years, 58.7% male) with 958 intracranial plaques were included. More intracranial plaques were found in the T2DM group than the non-T2DM group (4.80 ± 2.22 vs. 3.60 ± 1.78, P < 0.05). Patients with poorly-controlled T2DM exhibited higher culprit plaque enhancement ratio than patients with well-controlled T2DM and non-T2DM (2.32 ± 0.61 vs. 1.60 ± 0.62 and 1.39 ± 0.39; respectively, P < 0.05). After adjusting for other clinical variables, T2DM was independently associated with increased intracranial plaque number (β = 0.269, P < 0.05), and HbA1c level was independently associated with culprit plaque enhancement ratio (β = 0.641, P < 0.05) in multivariate analysis. DATA CONCLUSION T2DM is associated with an increased intracranial plaque number. Higher HbA1c is associated with stronger plaque enhancement. 3D contrast enhanced MR vessel wall imaging may help better understand the association of T2DM and glycemic control with intracranial plaque. LEVEL OF EVIDENCE 1 TECHNICAL EFFICACY STAGE: 3.

Abstract
Background The aim of this study was to determine whether poor collaterals contribute to the occurrence of certain types of cognitive disorders in asymptomatic middle cerebral artery stenosis (MCAS). Material/Methods Patients aged ≥45 years with asymptomatic MCAS confirmed by computed tomography angiography were included in a single-center retrospective study. They did not have prior stroke or dementia. Within 7 days of admission, MRI and comprehensive neuropsychological assessment were performed. Cognitive assessment was conducted after 2 years. Two independent neuroradiologists evaluated intracranial collaterals by using the Miteff scale. Demographic date and Fazekas scores were collected. Results A total of 173 patients with asymptomatic MCAS (66% men, mean age 59.4 years) and 42 controls (45% men, mean age 61.4 years) were enrolled. Executive function, attention, and information-processing speed in poor collateral circulation patients were more frequently and more often impaired than those in good collateral circulation patients. Throughout the study period, patients with poor collateral circulation had worse executive function, attention, and information-processing speed than those with moderate collateral circulation. Over time, MCAS patients with good collateral circulation did not show an association with cognitive function. Conclusions MCAS patients with moderate and poor collateral circulation have impairment of ≥1 cognitive domain over time. The affected domains are consistent with the profile of vascular cognitive impairment. Good collateral circulation is more important in patients with MCAS, and is associated with less risk of cognitive disorders.

Abstract
BACKGROUND AND PURPOSE Diabetes mellitus is a specific risk factor for intracranial atherosclerosis (ICAS) regardless of race. However, it is largely unknown whether poor glycemic control is associated with the severity of ICAS in diabetic patients. METHODS We selected diabetic patients with acute ischemic stroke who were prospectively registered between March 2005 and December 2015. The patients who had a high-risk source of cardiogenic embolism were excluded. ICAS was graded from 0 to 3 by the number of significant (≥50%) stenoses on intracranial magnetic resonance angiography, and was divided into 4 types: unilateral anterior, bilateral anterior, posterior, and anterior plus posterior. Ordinal and multinomial regression tests were applied for the factors influencing the number and types of ICAS. RESULTS A total of 774 patients with noncardioembolic acute ischemic stroke with diabetes were enrolled. The multiplicity of ICAS was independently associated with age (odds ratio [OR], 1.035 per 1 year, 1.018-1.052; P < .001), hypertension (OR, 1.992, 1.336-2.965; P = .001), and glycated hemoglobin (HbA1c; OR, 1.207 per 1%, 1.089-1.338; P < .001) in the ordinal regression model. In multinomial regression, bilateral anterior stenosis tended to be correlated with age (OR, 1.042, 1.008-1.077; P = .016) and HbA1c (OR, 1.201 per 1%, .991-1.520; P = .057). Both anterior and posterior stenoses were significantly associated with age (OR, 1.056, 1.029-1.084; P < .001), hypertension (OR, 2.584, 1.404-4.762; P = .002), and HbA1c (OR, 1.272, 1.070-1.511; P = .006). CONCLUSIONS Age, concomitant hypertension, and HbA1c were factors associated with multiple intracranial stenoses. Further study is warranted to elucidate whether poor glycemic control facilitates ICAS in diabetic patients.

Abstract
INTRODUCTION Whether adding percutaneous transluminal angioplasty and stenting (PTAS) to background medical treatment is effective for decreasing the incidence of stroke or death in patients with symptomatic intracranial atherosclerosis (ICAS) is still controversial. We perform a randomised controlled trial to examine the effectiveness and safety of an improved PTAS procedure for patients with ICAS. METHODS AND ANALYSIS A randomised controlled trial will be conducted in three hospitals in China. Eligible patients with ICAS will be randomly assigned to receive medication treatment (MT) plus PTAS or MT alone. The MT will be initiated immediately after randomisation, while the PTAS will be performed when patients report relief of alarm symptoms defined as sudden weakness or numbness. All patients will be followed up at 30 days, 3 and 12 months after randomisation. The primary end point will be the incidence of stroke or death at 30 days after randomisation. Secondary outcomes will be the incidence of ischaemic stroke in the territory of stenosis arteries, the incidence of in-stent restenosis, the Chinese version of the modified Rankin Scale and the Chinese version of the Stroke-Specific Quality of Life (CSQoL). ETHICS AND DISSEMINATION The study protocol is approved by institutional review boards in participating hospitals (reference number FZ20160003, 180PLA20160101 and 476PLA2016007). The results of this study will be disseminated to patients, physicians and policymakers through publication in a peer-reviewed journal or presentations in conferences. It is anticipated that the results of this study will improve the quality of the current PTAS procedure and guide clinical decision-making for patients with ICAS. TRIAL REGISTRATION NUMBER NCT02689037.
