Abstract
INTRODUCTION Acute ischemic stroke is a medical emergency caused by decreased blood flow to the brain, leading cause of long-term disability. Recanalization, one of the most concerning difficulties linked with intracranial arterial occlusion, has been used to reduce mortality in ischemic stroke treatment. The mismatch concepts MR PWI-DWI or DWI-FLAIR can help identify patients for thrombolysis. PURPOSE This paper introduces a novel method of predicting revascularization using the value of fluid-attenuated inversion recovery vascular hyperintensity FVH-DWI mismatch and DWI-FLAIR mismatch, which releases anterior circulation large vessel occlusion (LVO) after endovascular thrombectomy (EVT). Moreover, we present a new scoring system following anatomical region distributed for MCA territory called a DWI-FLAIR MISMATCH ASPECTS. RESULT Statistical analysis was performed to predict revascularization and functional outcome with 110 patients with anterior circulation LVO treated with EVT. We found that FVH-DWI mismatch was present in 71 patients (89.9 %) with complete revascularization and present in 8 patients (10.1 %) with no/partial revascularization, which had no significant difference (p = 0.12), and there was no significant difference between good functional outcome and poor functional outcome. Moreover, in 76 patients with DWI-FLAIR mismatch ASPECTS of > 6 point-group, present FVH-DWI mismatch in 57 patients (83.8 %) with complete revascularization had a significant difference as compared to 11 patients (16.2 %) with absent FVH-DWI mismatch (p < 0.05). The clinical outcome in complete revascularization is better than no/partial revascularization, and complete revascularization is independently associated with good functional outcomes (p < 0.05). CONCLUSION FVH-DWI mismatch paired with DWI-FLAIR mismatch ASPECTS > 6 points may be possible to predict revascularization in patients with anterior circulation LVO.

Abstract
OBJECTIVE For anterior circulation tandem occlusions, the optimal management strategy for extracranial carotid lesions is controversial. We aimed to compare the efficacy and safety of acute stenting (AS) with balloon angioplasty (BA) only. METHODS Clinical data were collected from 98 patients with anterior circulation tandem occlusion who underwent endovascular treatment at our center. Of these patients, 64 and 34 were assigned to the AS and BA groups, respectively. The clinical characteristics and outcome data of the 2 groups were analyzed and compared. RESULTS The proportion of patients with good outcomes was 59.2%. The AS group had a higher rate of successful recanalization (98.4% vs. 82.4%, P = 0.007) and a lower rate of occlusion of the responsible vessel at 90 days (14.1% vs. 32.4%, P = 0.039) than the BA group. The AS group was also significantly better than the BA group in terms of good outcomes (67.2% vs. 44.1%, P = 0.027), but there was no significant difference between the 2 groups in terms of 90-day mortality (6.3% vs. 8.8%, P = 0.691) and asymptomatic intracranial hemorrhage (6.3% vs. 5.9%, P = 1.000). Lower baseline National Institutes of Health Stroke Scale scores were associated with good outcomes (P < 0.001), and the presence of symptomatic intracranial hemorrhage was associated with 90-day mortality (P = 0.003). CONCLUSIONS Acute stent placement in patients with acute ischemic stroke due to anterior circulation tandem occlusion may have a better outcome than BA alone, and the safety of both approaches is comparable.

Abstract
PURPOSE To evaluate whether arterial and venous color-coded mCTA score may predict clinical outcome in anterior circulation acute ischemic stroke. METHODS Consecutive patients referred to the emergency department with anterior circulation acute ischemic stroke (AIS) were retrospectively reviewed at our center. All patients underwent multimodal brain computed tomography (CT) imaging, including non-contrast CT (NCCT) and multiphase computed tomography angiography (mCTA). Baseline collateral scores of color-coded mCTA, also known as ColorViz, and conventional mCTA were recorded. mCTA was assessed by a 6-point scale whereas color-coded mCTA was assessed by a 3-point scale. In the Color-coded maps, a different color is assigned to intracranial vessels based on the arrival time of the contrast medium and on a per-person adaptive threshold technique. We compared the radiological and clinical features of a group of patients who reached independency (defined as modified Rankin Scale score ≤ 2) with those of patients who did not. A multivariate logistic regression model was then used to assess the potential of color-coded mCTA scores to predict patients' outcome after AIS. RESULTS A total of 86 patients (36 M, 50 F) were enrolled in the study. Multivariate logistic regression showed that score 3 at Color-coded mCTA was a good predictor of favorable outcome (p = 0.003). Moreover, NIHSS at onset (p = 0.004) and discharge (p < 0.001) along with ischemic core area (p = 0.011) were significant predictors of favorable prognosis. CONCLUSION our data confirm that ColorViz is a useful and easily understandable neuroimaging tool that might have a predictive role in assessing the outcome of anterior circulation acute ischemic stroke patients regardless of revascularization therapy.

Abstract
BACKGROUND Endovascular treatment (EVT) is merely recommended as class of recommendation IIb for patients with ASPECTS <6 according to the American Heart Association guideline 2019. In addition, the best determined imaging technique for EVT in patient with ASPECTS<6 remains unknown. The objective of this study was to define the safety and efficacy of EVT for patients with ASPECTS<6 and investigate the superiority between MRI and CT for patient selection. METHODS A systematic search of PubMed, EMBASE, The Cochrane Library and other additional sources was performed for studies published with no publication period. Our study was conducted corresponding to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRIMA) guidelines. The analysis was performed using the Comprehensive Meta-Analysis (CMA) 2.0. RESULTS Five studies reporting data from 844 participants were included in our analysis according to the inclusion criteria. Consequently, EVT was associated with statistically significant higher functional independence compared with MT (OR 5.401, 95% CI 3.227-9.041). Whereas EVT was found to be related to lower mortality compared with MT based on eligible data (OR 0.461, 95% CI 0.329-0.647). No significant difference was identified in sICH between EVT and MT (OR 1.075, 95% CI 0.452-2.558). CONCLUSION According to the results of our study, we suggested that EVT is a preferred therapy in ACS patients with ASPECTS<6 in consideration of efficacy and safety. Furthermore, MRI did not show superiority over CT as no statistical difference was detected in all subgroups.

Abstract
BACKGROUND It remains unclear whether thrombolysis outcomes can be influenced by the affected vascular territory (i.e. anterior circulation stroke vs. posterior circulation stroke) in stroke patients owing to the lack of randomized controlled trials. AIMS Using multiple comprehensive databases, we searched for observational studies of the safety and efficacy of intravenous thrombolytics and intra-arterial treatment with or without intravenous thrombolytics in accordance with the affected vascular territory. We performed a systematic review and meta-analysis. We evaluated symptomatic intracerebral hemorrhage, all-type intracerebral hemorrhage, mortality, and functional outcomes at three months. The recanalization rate was assessed in the intra-arterial treatment group. SUMMARY OF REVIEW Twenty-one studies including a report from our own stroke registry were included through quantitative synthesis. Compared with the anterior circulation stroke group, the posterior circulation stroke group had a lower risk of ICH, including symptomatic intracerebral hemorrhage and all-type intracerebral hemorrhage, after intravenous thrombolytics and tended to have favorable functional outcomes at three months. Mortality was similar between the two groups. Regarding intra-arterial treatment, the symptomatic intracerebral hemorrhage and post-procedural recanalization rates were comparable between the two groups, although the posterior circulation stroke group had a higher mortality risk and lower tendency for a favorable functional outcome. CONCLUSIONS Safety and efficacy of thrombolysis in posterior circulation stroke depends on involvement of large vessel occlusion and reperfusion modality such that intravenous thrombolytics is more effective and safer than in anterior circulation stroke; the safety and efficacy of intra-arterial treatment is comparable or lower than anterior circulation stroke. Considering the limitations of our meta-analysis, further studies are needed to provide high level evidence of a beneficial effect of intra-arterial treatment, and to identify patients' profiles associated with benefit of treatment.

Abstract
Aim: Posterior circulation stroke (PCS) has different clinical features and prognosis compared with anterior circulation stroke (ACS), and whether the effect of statin therapy on stroke prevention differs according to infarction location remains unclear. This post hoc analysis of the J-STARS study aimed to compare the usefulness of statin at different infarction locations (i.e., ACS and PCS). Methods: In the J-STARS study, 1578 patients were randomly assigned to the pravastatin or control group. The subjects were divided into two subgroups (ACS and PCS groups) based on the arteries responsible for the infarction. Cox proportional hazards models were used to investigate whether the all stroke recurrence rate was different between the ACS and PCS groups. Results: The PCS group (n = 499) had a significantly higher prevalence of diabetes than the ACS group (n = 1022) (30.7% vs. 19.8%, P < 0.001). During the follow-up (4.9 ± 1.4 years), the incidence of all stroke was significantly lower in the pravastatin group than in the control group among patients with PCS (adjusted hazard ratio [HR] 0.46, 95% confidence interval [CI] 0.25–0.83, P = 0.009); however, the stroke recurrence rates were not significantly different between both groups among patients with ACS (adjusted HR 1.32, 95% CI 0.93–1.88, P = 0.123). A significant interaction between the ACS and PCS groups in terms of pravastatin effects was noted (P = 0.003 for interaction). Conclusions: Pravastatin significantly reduced the recurrence rate of all stroke among patients with PCS. Thus, the effect of statin on the recurrence of stroke may differ according to infarction location.
