Abstract
BACKGROUND AND AIM To investigate the prognostic implication of body mass index (BMI) on clinical outcomes after acute ischemic and hemorrhagic stroke. METHODS The subjects of the study included adult patients with available baseline body weight and height data who had suffered an acute stroke and were registered in the Japan Stroke Data Bank-a hospital-based, multicenter stroke registration database-between January 2006 and December 2020. The outcome measures included unfavorable outcomes defined as a modified Rankin Scale [mRS] score of 5-6 and favorable outcomes (mRS 0-2) at discharge, and in-hospital mortality. Mixed effects logistic regression analysis was conducted to determine the relationship between BMI categories (underweight, normal weight, overweight, class I obesity, class II obesity;<18.5, 18.5-23.0, 23.0-25.0, 25-30, ≥30 kg/m2) and the outcomes, after adjustment for covariates. RESULTS A total of 56,230 patients were assigned to one of the following groups: ischemic stroke (IS, n=43,668), intracerebral hemorrhage (ICH, n=9,741), and subarachnoid hemorrhage (SAH, n=2,821). In the IS group, being underweight was associated with an increased likelihood of unfavorable outcomes (odds ratio, 1.47 [95%CI:1.31-1.65]) and in-hospital mortality (1.55 [1.31-1.83]) compared to outcomes in those with normal weight. Being overweight was associated with an increased likelihood of favorable outcomes (1.09 [1.01-1.18]). Similar associations were observed between underweight and these outcomes in specific IS subtypes (cardioembolic stroke, large artery stroke, and small vessel occlusion). Patients with a BMI≥30.0 kg/m2 was associated with an increased likelihood of unfavorable outcomes (1.44 [1.01-2.17]) and in-hospital mortality (2.42 [1.26-4.65]) in large artery stroke. In patients with ICH, but not those with SAH, being underweight was associated with an increased likelihood of unfavorable outcomes (1.41 [1.01-1.99]). CONCLUSIONS BMI substantially impacts functional outcomes following IS and ICH. Lower BMI consistently affected post-stroke disability and mortality, while higher BMI values similarly affected these outcomes after large artery stroke.

Abstract
BACKGROUND Covert atrial fibrillation (AF) is a major cause of cryptogenic stroke. This study investigated whether a dose-dependent relationship exists between the frequency of premature atrial contractions (PACs) and AF detection in patients with cryptogenic stroke using an insertable cardiac monitor (ICM). METHODS We enrolled consecutive patients with cryptogenic stroke who underwent ICM implantation between October 2016 and September 2020 at 8 stroke centers in Japan. Patients were divided into 3 groups according to the PAC count on 24-hour Holter ECG: ≤200 (group L), >200 to ≤500 (group M), and >500 (group H). We defined a high AF burden as above the median of the cumulative duration of AF episodes during the entire monitoring period. We evaluated the association of the frequency of PACs with AF detection using log-rank trend test and Cox proportional hazard model and with high AF burden using logistic regression model, adjusting for age, sex, CHADS2 score. RESULTS Of 417 patients, we analyzed 381 patients with Holter ECG and ICM data. The median age was 70 (interquartile range, 59.5-76.5), 246 patients (65%) were males, and the median duration of ICM recording was 605 days (interquartile range, 397-827 days). The rate of new AF detected by ICM was higher in groups with more frequent PAC (15.5%/y in group L [n=277] versus 44.0%/y in group M [n=42] versus 71.4%/y in group H [n=62]; log-rank trend P<0.01). Compared with group L, the adjusted hazard ratios for AF detection in groups M and H were 2.11 (95% CI, 1.24-3.58) and 3.23 (95% CI, 2.07-5.04), respectively, and the adjusted odds ratio for high AF burden in groups M and H were 2.57 (95% CI, 1.14-5.74) and 4.25 (2.14-8.47), respectively. CONCLUSIONS The frequency of PACs was dose-dependently associated with AF detection in patients with cryptogenic stroke.

Abstract
BACKGROUND Atrial fibrillation (AF) is known to be a strong risk factor for stroke. However, the risk of stroke recurrence in patients with cryptogenic stroke with AF detected after stroke by an insertable cardiac monitor (ICM) is not well known. We sought to evaluate the risk of ischemic stroke recurrence in patients with cryptogenic stroke with and without ICM-detected AF. METHODS AND RESULTS We retrospectively reviewed patients with cryptogenic stroke who underwent ICM implantation at 8 stroke centers in Japan. Cox regression models were developed using landmark analysis and time-dependent analysis. We set the target sample size at 300 patients based on our estimate of the annualized incidence of ischemic stroke recurrence to be 3% in patients without AF detection and 9% in patients with AF detection. Of the 370 patients, 121 were found to have AF, and 110 received anticoagulation therapy after AF detection. The incidence of ischemic stroke recurrence was 4.0% in 249 patients without AF detection and 5.8% in 121 patients with AF detection (P=0.45). In a landmark analysis, the risk of ischemic stroke recurrence was not higher in patients with AF detected ≤90 days than in those without (hazard ratio, 1.47 [95% CI, 0.41-5.28]). In a time-dependent analysis, the risk of ischemic stroke recurrence did not increase after AF detection (hazard ratio, 1.77 [95% CI, 0.70-4.47]). CONCLUSIONS The risk of ischemic stroke recurrence in patients with cryptogenic stroke with ICM-detected AF, 90% of whom were subsequently anticoagulated, was not higher than in those without ICM-detected AF.

Abstract
BACKGROUND AND OBJECTIVE The association between focal vs nonfocal presenting symptom and diffusion-weighted imaging (DWI) positivity in relation to onset-to-imaging time in patients with transient neurologic events remains unclear. We hypothesize that episodes consisting of focal symptoms would have proportionally higher DWI-positive imaging at later onset-to-imaging times. METHODS Patients with transient neurologic symptoms and a normal neurologic examination who had DWI in the combined data set of 3 cohort studies were included. We used logistic regression models to evaluate the association between each type of presenting symptom (motor weakness, speech impairment, sensory symptoms, vision loss, diplopia, gait instability, dizziness, headache, presyncope, and amnesia) and DWI positivity after adjusting for clinical variables (age, sex, history of stroke, dyslipidemia, coronary artery disease, atrial fibrillation, symptoms duration [<10, 10-59, ≥60 minutes, or unclear], and study source). We stratified the results by onset-to-imaging time categories (<6 hours, 6-23 hours, and ≥24 hours). RESULTS Of the total 2,411 patients (1,345 male, median age 68 years), DWI-positive lesions were detected in 598 patients (24.8%). The prevalence of DWI positivity was highest in those with motor weakness (34.7%), followed by speech impairment (33.5%). In a multivariable analysis, the presence of motor weakness, speech impairment, and sensory symptoms was associated with DWI positivity, while vision loss and headache were associated with lower odds of DWI positivity, but nevertheless had 13.6% and 15.3% frequency of DWI positive. The odds of being DWI positive varied by onset-to-imaging time categories for motor weakness, with greater odds of being DWI positive at later imaging time (<6 hours: odds ratio [OR] 1.25, 95% confidence interval [CI] 0.84-1.87; 6-23 hours: OR 2.24, 95% CI 1.47-3.42; and ≥24 hours: OR 2.42, 95% CI 1.74-3.36; interaction p = 0.033). Associations of other symptoms with DWI positivity did not vary significantly by time categories. DISCUSSION We found that onset-to-imaging time influences the relationship between motor weakness and DWI positivity in patients with transient neurologic events. Compared with motor, speech, and sensory symptoms, visual or nonfocal symptoms carry a lower but still a substantive association with DWI positivity.

Abstract
AIM The nationwide verification of intravenous thrombolysis (IVT) was rarely performed after the extension of the therapeutic time window of alteplase or after the expansion of mechanical thrombectomy (MT). We aimed to examine the long-term change in accurate real-world outcomes of IVT in patients with acute ischemic stroke (AIS) using the Japan Stroke Databank, a representative Japan-wide stroke database. METHODS We extracted all patients with AIS who received IVT with alteplase between October 11, 2005, the approval date for alteplase use for AIS in Japan, and December 31, 2020. Patients were categorized into three groups using two critical dates in Japan as cutoffs: the official extension date of the therapeutic time window for IVT to within 4.5 h of symptom onset and the publication date of the revised guideline, where the evidence level of MT was heightened. We assessed the yearly trend of IVT implementation rates and the secular changes and three-group changes in clinical outcomes at discharge. RESULTS Of 124,382 patients with AIS, 9,569 (7.7%) received IVT (females, 41%; median age, 75 years). The IVT implementation rate has generally increased over time and plateaued in recent years. The proportion of favorable outcomes (modified Rankin Scale score of 0-2) increased yearly over 15 years. The results of the changes in the outcomes of the three groups were similar to those of the annual changes. CONCLUSIONS We revealed that IVT implementation rates in patients with AIS increased, and the functional outcome in these patients improved over 15 years. Therefore, the Japanese IVT dissemination strategy is considered appropriate and effective.

Abstract
Background Anemia can occur due to an aspiration maneuver of blood with thrombi during mechanical thrombectomy (MT) for stroke. However, the association between postoperative anemia and stroke outcomes is unknown. Methods In a registry-based hospital cohort, consecutive patients with acute ischemic stroke who underwent MT were retrospectively recruited. Patients were divided into the following three groups according to their hemoglobin (Hb) concentrations within 24 h after MT; no anemia (Hb concentrations ≥13 g/dL for men and ≥ 12 g/dL for women), mild anemia (Hb concentrations of 11-13 g/dL and 10-12 g/dL, respectively), and moderate-to-severe anemia (Hb concentrations <11 g/dL and < 10 g/dL, respectively). A 3-month modified Rankin Scale score of 0-2 indicated a favorable outcome. Results Of 470 patients, 166 were classified into the no anemia group, 168 into the mild anemia group, and 136 into the moderate-to-severe anemia group. Patients in the moderate-to-severe anemia group were older and more commonly had congestive heart failure than those in the other groups. Patients in the moderate-to-severe anemia group also had more device passes than those in the other groups (p < 0.001). However, no difference was observed in the rate of final extended thrombolysis in cerebral infarction ≥2b reperfusion or intracranial hemorrhage among the groups. A favorable outcome was less frequently achieved in the moderate-to-severe anemia group than in the no anemia group (adjusted odds ratio, 0.46; 95% confidence interval, 0.26-0.81) independent of the baseline Hb concentration. A restricted cubic spline model with three knots showed that the adjusted odds ratio for a favorable outcome was lower in patients with lower Hb concentrations within 24 h after MT. Conclusion Moderate-to-severe anemia within 24 h after MT is independently associated with a reduced likelihood of a favorable outcome.

Abstract
BACKGROUND An insertable cardiac monitor (ICM) and transesophageal echocardiography (TEE) are useful for investigating potential embolic sources in cryptogenic stroke, of which atrial fibrillation (AF) is a critical risk factor for stroke recurrence. The association of left atrial appendage flow velocity (LAA-FV) on TEE with ICM-detected AF is yet to be elucidated. METHODS CRYPTON-ICM (CRYPTOgenic stroke evaluation in Nippon using ICM) is a multicenter registry of cryptogenic stroke with ICM implantation, and patients whose LAA-FV was evaluated on TEE were enrolled. The primary outcome was the detection of AF (> 2 min) on ICM. Receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off of LAA-FV, and factors associated with ICM-detected AF were assessed. RESULTS A total of 307 patients (age 66.6 ± 12.3 years; 199 males) with median follow-up of 440 (interquartile range 169-726) days were enrolled; AF was detected in 101 patients. The lower-tertile LAA-FV group had older age, more history of congestive heart failure, and higher levels of B-type natriuretic peptide (BNP) or N-terminal proBNP (all P < 0.05). On ROC analysis, LAA-FV < 37.5 cm/s predicted ICM-detected AF with sensitivity of 26.7% and specificity of 92.2%. After adjustment for covariates, the lower tertile of LAA-FV (hazard ratio [HR], 1.753 [1.017-3.021], P = 0.043) and LAA-FV < 37.5 cm/s (HR 1.987 [1.240-3.184], P = 0.004) predicted ICM-detected AF. CONCLUSIONS LAA-FV < 37.5 cm/s predicts AF. TEE is useful not only to evaluate potential embolic sources, but also for long-term detection of AF on ICM by measuring LAA-FV in cryptogenic stroke. http://www.umin.ac.jp/ctr/ (UMIN000044366).

Abstract
BACKGROUND Clinical outcomes of unknown onset stroke (UOS) are influenced by the enlargement of the therapeutic time window for reperfusion therapy. This study aimed to investigate and describe the characteristics and clinical outcomes of patients with UOS. METHODS Patients with acute ischemic stroke (AIS) who were admitted within 24 h of their last known well time, from January 2017 to December 2020, were included. Data were obtained from a long-lasting nationwide hospital-based multicenter prospective registry: the Japan Stroke Data Bank. The co-primary outcomes were the National Institutes of Stroke Scale (NIHSS) scores on admission and unfavorable outcomes at discharge, corresponding to modified Rankin Scale (mRS) scores of 3-6. RESULTS Overall, 26,976 patients with AIS were investigated. Patients with UOS (N = 5783, 78 ± 12 years of age) were older than patients with known onset stroke (KOS) (N = 21,193, 75 ± 13 years of age). Age, female sex, higher premorbid mRS scores, atrial fibrillation, and congestive heart failure were associated with UOS in multivariate analysis. UOS was associated with higher NIHSS scores (median = 8 [interquartile range [IQR]: 3-19] vs. 4 [1-10], adjusted incidence rate ratio = 1.37 [95% CI: 1.35-1.38]) and unfavorable outcomes (52.1 vs. 33.6%, adjusted odds ratio = 1.27 [1.14-1.40]). Intergroup differences in unfavorable outcomes were attenuated among females (1.12 [0.95-1.32] vs. males 1.38 [1.21-1.56], P = 0.040) and in the subgroup that received reperfusion therapy (1.10 [0.92-1.33] vs. those who did not receive therapy 1.23 [1.08-1.39], P = 0.012). CONCLUSIONS UOS was associated with unfavorable outcomes but to a lesser degree among females and patients receiving reperfusion therapy.

Abstract
BACKGROUND AND PURPOSE Differences in measurement of the extent of acute ischemic stroke using the Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) by non-contrast computed tomography (CT-ASPECTS stratum) and diffusion-weighted imaging (DWI-ASPECTS stratum) may impact the efficacy of endovascular therapy (EVT) in patients with a large ischemic core. METHODS The RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan-Large IscheMIc core Trial) was a multicenter, open-label, randomized clinical trial that evaluated the efficacy and safety of EVT in patients with ASPECTS of 3-5. CT-ASPECTS was prioritized when both CT-ASPECTS and DWI-ASPECTS were measured. The effects of EVT on the modified Rankin Scale (mRS) score at 90 days were assessed separately for each stratum. RESULTS Among 183 patients, 112 (EVT group, 53; No-EVT group, 59) were in the CT-ASPECTS stratum and 71 (EVT group, 40; No-EVT group, 31) in the DWI-ASPECTS stratum. The common odds ratio (OR) (95% confidence interval) of the EVT group for one scale shift of the mRS score toward 0 was 1.29 (0.65-2.54) compared to the No-EVT group in CT-ASPECTS stratum, and 6.15 (2.46-16.3) in DWI-ASPECTS stratum with significant interaction between treatment assignment and mode of imaging study (P=0.002). There were significant interactions in the improvement of the National Institutes of Health Stroke Scale score at 48 hours (CT-ASPECTS stratum: OR, 1.95; DWIASPECTS stratum: OR, 14.5; interaction P=0.035) and mortality at 90 days (CT-ASPECTS stratum: OR, 2.07; DWI-ASPECTS stratum: OR, 0.23; interaction P=0.008). CONCLUSION Patients with ASPECTS of 3-5 on MRI benefitted more from EVT than those with ASPECTS of 3-5 on CT.

Abstract
Background We aimed to clarify which time-to-maximum of the tissue residue function (Tmax) mismatch ratio is useful in predicting anterior intracranial atherosclerotic stenosis (ICAS)-related large-vessel occlusion (LVO) before endovascular therapy. Methods and Results Patients with ischemic stroke who underwent perfusion-weighted imaging before endovascular therapy for anterior intracranial LVO were divided into those with ICAS-related LVO and those with embolic LVO. Tmax ratios of >10 s/>8 s, >10 s/>6 s, >10 s/>4 s, >8 s/>6 s, >8 s/>4 s, and >6 s/>4 s were considered Tmax mismatch ratios. Binominal logistic regression was used to identify ICAS-related LVO, and the adjusted odds ratio (aOR) and 95% CI for each Tmax mismatch ratio increase of 0.1 were calculated. A similar analysis was performed for ICAS-related LVO with and without embolic sources, using embolic LVO as the reference. Of 213 patients (90 women [42.0%]; median age, 79 years), 39 (18.3%) had ICAS-related LVO. The aOR (95% CI) per 0.1 increase in Tmax mismatch ratio in ICAS-related LVO with embolic LVO as reference was lowest with Tmax mismatch ratio >10 s/>6 s (0.56 [0.43-0.73]). Multinomial logistic regression analysis also showed the lowest aOR (95% CI) per 0.1 increase in Tmax mismatch ratio with Tmax >10 s/>6 s (ICAS-related LVO without embolic source: 0.60 [0.42-0.85]; ICAS-related LVO with embolic source: 0.55 [0.38-0.79]). Conclusions A Tmax mismatch ratio of >10 s/>6 s was the optimal predictor of ICAS-related LVO compared with other Tmax profiles, with or without an embolic source before endovascular therapy.

Abstract
Implantable loop recorders (ILRs) are useful for the detection of atrial fibrillation (AF) in patients with cryptogenic stroke (CS). P-wave terminal force in lead V1 (PTFV1) is associated with AF detection; however, data on the association between PTFV1 and AF detection using ILRs in patients with CS are limited. Consecutive patients with CS with implanted ILRs from September 2016 to September 2020 at eight hospitals in Japan were studied. PTFV1 was calculated by 12-lead ECG before ILRs implantation. An abnormal PTFV1 was defined as ≥ 4.0 mV × ms. The AF burden was calculated as a proportion based on the duration of AF to the total monitoring period. The outcomes included AF detection and large AF burden, which was defined as ≥ 0.5% of the overall AF burden. Of 321 patients (median age, 71 years; male, 62%), AF was detected in 106 patients (33%) during the median follow-up period of 636 days (interquartile range [IQR], 436-860 days). The median time from ILRs implantation to AF detection was 73 days (IQR, 14-299 days). An abnormal PTFV1 was independently associated with AF detection (adjusted hazard ratio, 1.71; 95% confidence interval [CI], 1.00-2.90). An abnormal PTFV1 was also independently associated with a large AF burden (adjusted odds ratio, 4.70; 95% CI, 2.50-8.80). In patients with CS with implanted ILRs, an abnormal PTFV1 is associated with both AF detection and a large AF burden.Clinical Trial Registration Information: UMIN Clinical Trials Registry 000044366.

Abstract
Purpose:
The purpose of this study was to examine the associations between oral anticoagulants (OACs) at onset and outcomes in acute ischemic stroke (AIS) patients with atrial fibrillation.
Methods:
AIS patients with comorbidity of atrial fibrillation (aged ≥18 years, pre-stroke modified Rankin Scale [mRS] 0-2) admitted within 24 hours after onset from January 2017 to December 2020 were examined from a long-lasting nationwide hospital-based multicenter prospective registry, the Japan Stroke Data Bank. Patients were classified into 3 groups according to anticoagulants at onset: no-anticoagulant group, warfarin group and DOAC group. The co-primary outcomes were the National Institutes of Stroke Scale (NIHSS) on admission and favorable outcome at discharge, corresponding to the mRS of 0-2. Mixed effects logistic regression was performed to examine the association between antithrombotic agents and these outcomes.
Results:
Of a total of 6,838 patients, 4,249 (62.1 %) patients were classified into the no-anticoagulant group, 907 (13.3 %) into warfarin group and 1,682 (24.6 %) into DOACs group. Median NIHSS score on admission was 7 [interquartile range: 2-19] in the warfarin group and 5 [2-15] in the DOAC group, versus 9 [3-20] in the no-anticoagulant group. Both warfarin and DOAC groups had lower NIHSS scores as compared to no-antithrombotic group (adjusted incidence rate ratio 0.96 [95% confidence interval 0.94-0.99] and 0.81 [0.79-0.83], respectively) after adjustment by age, sex, hypertension (HT), dyslipidemia (DL), diabetes mellitus (DM) and history of stroke. The rate of favorable outcome at discharge was 41.5 % in no-anticoagulant group, 42.0% in warfarin group and 48.1 % in DOACs group. In multivariable analysis, sex, NIHSS on admission, HT, DL, DM, history of stroke and intravenous thrombolysis and mechanical thrombectomy, DOACs group more frequently had favorable outcome (odds ratio 1.20 [95% CI 1.03-1.40]) than no-anticoagulant group, but warfarin group did not (1.05 [0.86-1.27]).
Conclusion:
Taking DOACs prior to onset appears associated with milder stroke severity and a more favorable outcome following acute ischemic stroke in patients with atrial fibrillation.

Abstract
Background:
To determine secular changes in severity and functional outcomes of acute atrial fibrillation (AF)-associated stroke patients using a large population.
Methods:
Ischemic stroke patients with known AF or AF diagnosed after stroke onset, who were registered within 7 days after symptom onset into a hospital-based prospective registry, Japan Stroke Data Bank, from Jan 2000 to Dec 2020 were compared with those without AF. The co-primary outcomes were the initial neurological severity assessed by NIHSS and favorable outcome assessed by mRS of 0 to 2 at hospital discharge. Secondary outcomes included unfavorable outcome assessed by mRS of 5 to 6 and in-hospital death.
Results:
Of 142,351 patients studied, 33,870 had AF (women 45.1%, median age 79 years, non-valvular 94.3%). Patients with AF had higher initial NIHSS score (median 9 vs. 3, adjusted coefficient 5.383, 95% CI 5.245 - 5.520) as compared to patients without AF (women 38.2%, median age 79 years). Anticoagulation prior to the index stroke showed a significant interaction with the frequency of the NIHSS score ≥10 in patients with AF relative to those without AF (aOR: 2.047 for anticoagulated patients vs. 4.189 for the others). The NIHSS score decreased over the 21-year period in AF patients (adjusted coefficient -0.104, 95% CI -0.133 - -0.074 per year). Favorable outcome was less common in patients with AF than those without AF in unadjusted analysis (48.4% vs. 70.4%) but was more common after multivariable adjustment including the initial NIHSS score (aOR 1.096, 95% CI 1.040 - 1.156). Unfavorable outcome (aOR 1.108) and in-hospital death (1.506) were also more common in AF patients. The proportion of favorable outcome showed an increase over time (aOR 1.018, 95% CI 1.009 - 1.026 per year) in AF patients but the increase was no longer significant after further adjustment by receiving reperfusion therapy (1.007, 0.998 - 1.016). The proportion of unfavorable outcome and that of in-hospital death showed a yearly decrease over time.
Conclusions:
AF patients showed favorable clinical outcome after ischemic stroke relative to patients without AF by adjustment using the NIHSS score and others. Initial stroke severity became milder and functional outcomes tended to improve in AF patients during the past 21 years.

Abstract
Background and Purpose:
Whether specific patient groups have benefited from advances of treatment technologies including acute reperfusion therapy is uncertain. We aimed to investigate long-term trends of acute reperfusion therapy and functional outcomes according to the stroke severity using a large clinical registry.
Methods:
In the nationwide, hospital-based, multicenter, prospective registry cohort from the Japan Stroke Data Bank between January 2000 and December 2020, patients with ischemic stroke were studied. The baseline National Institutes of Health Stroke Scale (NIHSS) score of 10 or more was considered as possible large vessel occlusions (LVOs). Secular changes were assessed per 5-year categories (2000-2005, 2006-2010, 2011-2015, 2016-2020). Outcomes included favorable outcome (mRS score was 0 to 2 at discharge), and in-hospital mortality.
Results:
Of 235,695 patients, 127,741 ischemic stroke patients (76,850 men [60.2 %]; median age 75, [interquartile range, 66-82] years) with available data on NIHSS score were analyzed. NIHSS score was ≥10 in 31,747 patients (24.9%). In both patients with NIHSS ≥10 and those with NIHSS <10, the frequencies of intravenous thrombolysis (1.6% to 26.5%, and 0.3% to 6.9%, respectively) and endovascular therapy (2.0% to 29.8%, and 0.8% to 3.8%, respectively) increased from the 2000-2005 period to the 2015-2020 period. In patients with NIHSS ≥10, favorable outcome was more frequent in the 2015-2020 cohort than that in the 2000-2005 cohort (adjusted odds ratio, 1.63; [95% CI, 1.44-1.85]). In contrast, patients with NIHSS <10 had a decreased favorable outcome in the 2015-2020 cohort than that in the 2000-2005 cohort (adjusted odds ratio, 0.80; 95% CI, [0.75-0.85]). In-hospital mortality decreased in both patients with NIHSS ≥10 and NIHSS <10 per step on the 5-year categories.
Conclusions:
Over the 20-year period, acute reperfusion therapy has increasingly been provided to patients with NIHSS ≥10. Favorable outcomes significantly increased in patients with NIHSS ≥10 but decreased in those with NIHSS <10 over time. In-hospital mortality decreased across all NIHSS scores.

Abstract
Purpose:
The purpose of this study was to determine the associations between antithrombotic agents at onset and outcomes in intracerebral hemorrhage (ICH) patients.
Methods:
ICH patients admitted within 24 hours after onset from January 2017 to December 2020 were examined from a long-lasting nationwide hospital-based multicenter prospective registry, the Japan Stroke Data Bank. Patients were classified into 4 groups according to types of antithrombotic agents at onset: no-antithrombotic, antiplatelet, warfarin, and DOAC groups. Patients with combination of antiplatelet and anticoagulant agents were classified into respective anticoagulant groups. The outcomes were NIHSS on admission, in-hospital death and unfavorable outcome corresponding to mRS of 5-6 at discharge.
Results:
Of a total of 9,948 ICH patients (female: 4,329, age 70±15 years old), 77.4% of patients were classified into the no-antithrombotic group, 13.0% into the antiplatelet group, 3.9% into the warfarin group and 5.7% into the DOAC group. Median NIHSS on admission was 12 (interquartile range: 5-22), 13 (5-26), 15 (5-30) and 13 (6-24), respectively. In multivariable analysis, the warfarin group was significantly associated with higher NIHSS on admission (adjusted incidence rate ratio, 1.08 [95% CI, 1.05-1.12], setting the no-antithrombotic group as reference), but the antiplatelet group (1.01 [0.99-1.03]) or the DOAC group (0.97 [0.94-1.00]) was not. The rate of in-hospital death was 13.0% in the no-antithrombotic group, 17.8% in the antiplatelet group, 27.3% in the warfarin group and 18.9% in the DOAC group and that of unfavorable outcome was 30,8%, 41.9%, 48.6% and 41.5%, respectively. In multivariable analysis, the warfarin group was significantly associated with in-hospital death and unfavorable outcome (adjusted odds ratio: 1.62 [95% CI, 1.07-2.46] and 1.79 [1.23-2.6], respectively, setting the no-antithrombotic group as reference), but the antiplatelet group (1.14 [0.87-1.36], 1.11 [0.90-1.36]) or the DOAC group (1.07 [0.72-1.60], 1.27 [0.90-1.78]) was not.
Conclusion:
ICH patients taking warfarin at onset had higher NIHSS on admission, in-hospital death and unfavorable outcome compared to those without antithrombotic agents, but those taking DOAC did not.

Abstract
BACKGROUND The single-device simplicity for mechanical thrombectomy (MT) is now challenged by the complementary efficacy of dual-device first-line with a stent retriever and an aspiration catheter. OBJECTIVE To compare the outcomes after MT initiated with a single device vs dual devices in acute anterior circulation large vessel occlusion. METHODS Patients who underwent MT for acute internal carotid artery (ICA) or M1 occlusion between 2015 and 2020 were retrospectively analyzed. We divided patients into 2 groups: single-device first-line, defined as patients who underwent first-device pass with either a stent retriever or aspiration catheter, and dual-device first-line, defined as first-device pass with both devices. RESULTS One hundred forty-one patients were in the single-device group, and 119 were in the dual-device group. In the dual-device group, coiling or kinking of the extracranial ICA was more frequent ( P = .07) and the guide catheters were less frequently navigated to the ICA ( P < .001). 37% of the single-device group was converted to dual-device use. The proportions of mTICI ≥ 2c after the first pass were similar (33% vs 32%. adjusted odds ratio 0.91, 95% CI 0.51-1.62). An mRS score of 0 to 2 at 3 months was achieved similarly (53% vs 48%, P = .46). The total cost for thrombectomy devices was lower in the single-device group ( P < .001). CONCLUSION The proportions of first-pass mTICI ≥ 2c were not different between the 2 groups with similar functional outcomes, although the dual-device group more likely to have unfavorable vascular conditions.

A 57-year-old man presented with headache, transient right upper extremity weakness and numbness one month after recovery from coronavirus disease 2019 (COVID-19). His medical history included Graves' disease and IgG4-related ophthalmic disease. He had been administered prednisolone. His weakness and numbness were transient and not present on admission. Contrast-enhanced CT and MRI of the head showed thrombi in the superior sagittal sinus, right transverse sinus, sigmoid sinus, and the right internal jugular vein. Digital subtraction angiography showed occlusion at the same sites and mild perfusion delay in the left frontoparietal lobe. We diagnosed the patient with cerebral venous sinus thrombosis and treated him with anticoagulation. The thrombi partially regressed three months later, and perfusion delay became less noticeable. Cerebral venous sinus thrombosis is an important complication of COVID-19. Patients with predisposing factors, including Graves' disease and IgG4-related ophthalmic disease, may be at increased risk of developing cerebral venous sinus thrombosis even after recovery from COVID-19.

Abstract
Objective To evaluate whether changes in the practice of mechanical thrombectomy could affect the clinical outcomes during the coronavirus disease (COVID-19) pandemic. Methods Patients who underwent mechanical thrombectomy from April 2019 to March 2021 for anterior circulation proximal large artery occlusion in our institute were divided into two groups of pre- and post-COVID-19, with April 2020 assumed to be the start of the COVID-19 era with the first declaration of a state of emergency. We compared patient characteristics, proportions of patient selection depending on rapid processing of perfusion and diffusion (RAPID) CT perfusion, outcomes including treatment variables such as time and reperfusion status, and patient independence at 3 months. Results Data for 112 patients (median age, 79 years; 44 females) were included in the analysis. A total of 50 patients were assigned to the pre-COVID-19 group (45%). More patients were selected with RAPID CT perfusion in the post-COVID-19 compared with the pre-COVID-19 (69% vs. 16%; P <0.001). Treatment details and clinical outcomes did not differ between the groups, including the door-to-puncture time (median [interquartile range], 66 [54-90] min vs. 74 [61-89] min; P = 0.15), proportions of significant reperfusion (82% vs. 87%; P = 0.60), and modified Rankin scale score of ≤2 at 3 months (46% vs. 45%; P >0.99). Multivariate logistic regression analysis for the clinical outcome of modified Rankin scale score of ≤2 at 3 months was performed and included the following factors: age, sex, the onset-to-door time, significant reperfusion, and pre- and post-COVID-19. The treatment period did not influence the outcomes (post-COVID-19 group, odds ratio, 0.79; 95% confidence interval, 0.34-1.85, P = 0.59). Conclusion In the setting of a limited access to emergency MRI during the COVID-19 pandemic, RAPID CT perfusion was performed significantly more often. Changes in the practice of mechanical thrombectomy with the protected code stroke did not bring the different level of treatment and clinical outcomes as before.

Abstract
Background: Although tortuosity of the internal carotid artery (ICA) can pose a significant challenge when performing mechanical thrombectomy, few studies have examined the impact of ICA tortuosity on mechanical thrombectomy outcomes. Methods: In a registry-based hospital cohort, consecutive patients with anterior circulation stroke in whom mechanical thrombectomy was attempted were divided into 2 groups: those with tortuosity in the extracranial or cavernous ICA (tortuous group) and those without (nontortuous group). The extracranial ICA tortuosity was defined as the presence of coiling or kinking. The cavernous ICA tortuosity was defined by the posterior deflection of the posterior genu or the shape resembling Simmons-type catheter. Outcomes included first pass effect (FPE; extended Thrombolysis in Cerebral Infarction score 2c/3 after first pass), favorable outcome (3-month modified Rankin Scale score of 0–2), and intracranial hemorrhage. Results: Of 370 patients, 124 were in the tortuous group (extracranial ICA tortuosity, 35; cavernous ICA tortuosity, 70; tortuosity at both sites, 19). The tortuous group showed a higher proportion of women and atrial fibrillation than the nontortuous group. FPE was less frequently achieved in the tortuous group than the nontortuous group (21% versus 39%; adjusted odds ratio, 0.45 [95% CI, 0.26–0.77]). ICA tortuosity was independently associated with the longer time from puncture to extended Thrombolysis in Cerebral Infarction ≥2b reperfusion (β=23.19 [95% CI, 13.44–32.94]). Favorable outcome was similar between groups (46% versus 48%; P=0.87). Frequencies of any intracranial hemorrhage (54% versus 42%; adjusted odds ratio, 1.61 [95% CI, 1.02–2.53]) and parenchymal hematoma (11% versus 6%; adjusted odds ratio, 2.41 [95% CI, 1.04–5.58]) were higher in the tortuous group. In the tortuous group, the FPE rate was similar in patients who underwent combined stent retriever and contact aspiration thrombectomy and in those who underwent either procedure alone (22% versus 19%; P=0.80). However, in the nontortuous group, the FPE rate was significantly higher in patients who underwent combined stent retriever and contact aspiration (52% versus 35%; P=0.02). Conclusions: ICA tortuosity was independently associated with reduced likelihood of FPE and increased risk of postmechanical thrombectomy intracranial hemorrhage.

Abstract
Background The optimal timing of initiating oral anticoagulants after reperfusion therapy for ischemic stroke is unknown. Factors related to early initiation of rivaroxaban and differences in clinical outcomes of stroke patients with nonvalvular atrial fibrillation (NVAF) who underwent reperfusion therapy was investigated. Methods From data of 1,333 NVAF patients with ischemic stroke or transient ischemic attack (TIA) in a prospective multicenter study, patients who started rivaroxaban after intravenous thrombolysis and/or mechanical thrombectomy were included. The clinical outcomes included the composite of ischemic events (recurrent ischemic stroke, TIA, or systemic embolism) and major bleeding at 3 months. Results Among the 424 patients, the median time from index stroke to starting rivaroxaban was 3.2 days. On multivariable logistic regression analysis, infarct size (odds ratio [OR], 0.99; 95%CI, 0.99–1.00) was inversely and successful reperfusion (OR, 2.13; 95%CI, 1.24–3.72) was positively associated with initiation of rivaroxaban within 72 hours. 205 patients were assigned to the early group (< 72 hours) and 219 patients (≥ 72 hours) to the late group. Multivariable Cox regression models showed comparable hazard ratios between the two groups at 3 months for ischemic events (hazard ratio [HR], 0.18; 95%CI, 0.03–1.32) and major bleeding (HR, 1.80; 95%CI, 0.24–13.54). Conclusions Infarct size and results of reperfusion therapy were associated with the timing of starting rivaroxaban. There were no significant differences in the rates of ischemic events and major bleeding between patients after reperfusion therapy who started rivaroxaban < 72 hours and ≥ 72 hours after the index stroke.

Abstract
Background and Objectives Chronic kidney disease is a worldwide public health problem that is recognized as an established risk factor for stroke. It remains unclear whether its distribution and clinical impact are consistent across ischemic stroke subtypes in patients with renal impairment. We examined whether renal impairment was associated with the proportion of each stroke subtype vs ischemic stroke overall and with functional outcomes after each stroke subtype. Methods Study participants were 10,392 adult patients with an acute stroke from the register of the Japan Stroke Data Bank, a hospital-based multicenter stroke registration database, between October 2016 and December 2019, whose baseline serum creatinine levels or a dipstick proteinuria result were available. All ischemic strokes were classified according to the Trial of Org 10172 in Acute Stroke Treatment criteria. Unfavorable functional outcome was defined as modified Rankin Scale (mRS) score 3–6 at discharge. Mixed effect logistic regression was used to determine the relationship between the outcomes and the estimated glomerular filtration rate (eGFR), eGFR strata (<45, 45–59, ≥60 mL/min/1.73 m2), or dipstick proteinuria ≥1 adjusted for covariates. Results Overall, 2,419 (23%) patients had eGFR 45–59 mL/min/1.73 m2 and 1,976 (19%) had eGFR <45 mL/min/1.73 m2, including 185 patients (1.8%) receiving hemodialysis. Both eGFR 45–59 and eGFR <45 mL/min/1.73 m2 were associated with a higher proportion of cardioembolic stroke (odds ratio [OR], 1.21 [95% CI, 1.05–1.39] and 1.55 [1.34–1.79], respectively) and a lower proportion of small vessel occlusion (0.79 [0.69–0.90] and 0.68 [0.59–0.79], respectively). A similar association with the proportion of these 2 subtypes was proven in the analyses using decreased eGFR as continuous values. Both eGFR <45 mL/min/1.73 m2 and proteinuria were associated with unfavorable functional outcomes in patients with cardioembolic stroke (OR, 1.30 [95% CI, 1.01–1.69] and 3.18 [2.03–4.98], respectively) and small vessel occlusion (OR, 1.44 [1.01–2.07] and 2.08 [1.08–3.98], respectively). Discussion Renal impairment contributes to the different distributions and clinical effects across specific stroke subtypes, particularly evident in cardioembolic stroke and small vessel occlusion. This possibly indicates shared mechanisms of susceptibility and potentially enhancing pathways.

Abstract
Introduction:
The Japan Stroke Data Bank (JSDB) is a 20-year long ongoing hospital-based multicenter prospective registry of hospitalized patients with acute stroke/TIA based on a web database from 130 stroke centers distributed evenly over Japan.
Hypothesis:
Secular changes in the severity and functional outcome of stroke patients would be clarified by long-lasting hospital-based registries.
Methods:
Patients registered in JSDB within 7 days after stroke onset from Jan 2000 through Dec 2019 were studied. The initial severity was assessed by the NIHSS for ischemic stroke (IS) and intracerebral hemorrhage (ICH) and by the WFNS grading for subarachnoid hemorrhage (SAH). Outcomes at hospital discharge was assessed by the mRS.
Results:
Of a total 183,082 stroke patients, 135,268 (women in 39.8%) developed IS, 36,014 (women in 42.7%) developed ICH, and 11,800 (women in 67.2%) developed SAH. Median ages at onset increased and the NIHSS and WFNS scores decreased after multivariable-adjustment in all three stroke types. Patients with favorable outcome, corresponding to the mRS 0-2, significantly increased after age-adjustment in all three IS subtypes, remained increasing after further adjustment by NIHSS and stroke history only in cardioembolic stroke (OR 1.014, 95% CI 1.008-1.020, per year), and no longer increased after further adjustment by reperfusion therapy in any subtypes. Both the frequencies of unfavorable outcome, corresponding to the mRS 5-6, and in-hospital death, significantly decreased in cardioembolic stroke (OR 0.974, 95% CI 0.968-0.980) and large-artery atherosclerosis (OR 0.975, 95% CI 0.967-0.982, both for unfavorable outcome) after multivariable-adjustment. In ICH and SAH, favorable outcome significantly decreased after multivariable-adjustment, except for SAH in men. Both the frequencies of unfavorable outcome and death after SAH significantly decreased, but those after ICH were not. These findings were generally common to both sexes when separately analyzed.
Conclusions:
Short-term functional outcome improved in IS patients during the past 20 years presumably partly due to development of acute reperfusion therapy. The outcome of hemorrhagic stroke patients did not clearly show the improvement during the same duration.

Abstract
A 75-year-old female had a history of prior ischemic stroke with aphasia and right hemiplegia. Magnetic resonance angiography showed left internal carotid artery occlusion. She was successfully treated with intravenous recombinant tissue plasminogen activator (IV t-PA) and underwent endovascular thrombectomy (EVT). She was diagnosed with cardioembolic stroke due to the presence of atrial fibrillation and mitral valve stenosis, and warfarin was administered. However, she experienced large vessel occlusion twice within 2 years. Upon further analysis, transesophageal echocardiography revealed a mobile hyperechoic structure on the aortic valve, which was assumed to be an embolic source. Thus, we decided to perform mitral and aortic valve replacement. The excised aortic valve structure was suggested to be an example of Lambl's excrescence, histopathologically. After surgery, the patient had no recurrence for 3 years. Several cases of ischemic stroke associated with Lambl's excrescence have been reported, but definitive guidelines for managing patients with Lambl's excrescence do not currently exist. Surgical intervention for Lambl's excrescence with recurrent ischemic events may be important for preventing further recurrence.

Abstract
Background We retrospectively compared early‐ (<6 hours) versus late‐ (6–24 hours) presenting patients using perfusion‐weighted imaging selection and evaluated clinical/radiographic outcomes. Methods and Results Large vessel occlusion patients treated with mechanical thrombectomy from August 2017 to July 2020 within 24 hours of onset were retrieved from a single‐center database. Perfusion‐weighted imaging was analyzed by automated software and final infarct volume was measured semi‐automatically within 14 days. The primary end point was good outcome (modified Rankin Scale 0–2 at 90 days). Secondary end points were excellent outcome (modified Rankin Scale 0–1 at 90 days), symptomatic intracranial hemorrhage, and death. Clinical characteristics/radiological values including hypoperfusion volume and infarct growth velocity (baseline volume/onset‐to‐image time) were compared between the groups. Of 1294 patients, 118 patients were included. The median age was 74 years, baseline National Institutes of Health Stroke Scale score was 14, and core volume was 13 mL. The late‐presenting group had more female patients (67% versus 31%, respectively; P=0.001). No statistically significant differences were seen in good outcome (42% versus 53%, respectively; P=0.30), excellent outcome (26% versus 32%, respectively; P=0.51), symptomatic intracranial hemorrhage (6.5% versus 4.6%, respectively; P=0.74), and death (3.2% versus 5.7%, respectively; P=0.58) between the groups. The late‐presenting group had more atherothrombotic cerebral infarction (19% versus 6%, respectively; P=0.03), smaller hypoperfusion volume (median: 77 versus 133 mL, respectively; P=0.04), and slower infarct growth velocity (median: 0.6 versus 5.1 mL/h, respectively; P=0.03). Conclusions Patients with early‐ and late‐time windows treated with mechanical thrombectomy by automated perfusion‐weighted imaging selection have similar outcomes, comparable with those in randomized trials, but different in infarct growth velocities.

Abstract
Question Did the initial neurological severity and functional outcomes of patients with stroke change throughout a 20-year period? Findings In this hospital-based, multicenter, prospective registry involving 183 080 patients with acute stroke, initial neurological severity showed a decrease over time in all stroke types. Functional outcome at hospital discharge improved in patients with ischemic stroke but no longer showed improvement after adjustment by reperfusion therapy and others; it did not clearly improve in patients with hemorrhagic stroke. Meaning Twenty-year changes in functional outcomes after ischemic and hemorrhagic strokes showed different trends presumably partly owing to differences in the development of acute therapeutic strategies. Importance Whether recent changes in demographic characteristics and therapeutic technologies have altered stroke outcomes remains unknown. Objective To determine secular changes in initial neurological severity and short-term functional outcomes of patients with acute stroke by sex using a large population. Design, Setting, and Participants This nationwide, hospital-based, multicenter, prospective registry cohort study used the Japan Stroke Data Bank and included patients who developed acute stroke from January 2000 through December 2019. Patients with stroke, including ischemic and hemorrhagic strokes, who registered within 7 days after symptom onset were studied. Modified Rankin Scale scores were assessed at hospital discharge for all patients. Exposure Time. Main Outcomes and Measures Initial severity was assessed by the National Institutes of Health Stroke Scale for ischemic stroke and intracerebral hemorrhage and by the World Federation of Neurological Surgeons grading for subarachnoid hemorrhage. Outcomes were judged as favorable if the modified Rankin Scale score was 0 to 2 and unfavorable if 5 to 6. Results Of 183 080 patients, 135 266 (53 800 women [39.8%]; median [IQR] age, 74 [66-82] years) developed ischemic stroke, 36 014 (15 365 women [42.7%]; median [IQR] age, 70 [59-79] years) developed intracerebral hemorrhage, and 11 800 (7924 women [67.2%]; median [IQR] age, 64 [53-75] years) developed subarachnoid hemorrhage. In all 3 stroke types, median ages at onset increased, and the National Institutes of Health Stroke Scale and World Federation of Neurological Surgeons scores decreased throughout the 20-year period on multivariable analysis. In ischemic stroke, the proportion of favorable outcomes showed an increase over time after age adjustment (odds ratio [OR], 1.020; 95% CI, 1.015-1.024 for women vs OR, 1.015; 95% CI, 1.011-1.018 for men) but then stagnated, or even decreased in men, on multivariate adjustment including reperfusion therapy (OR, 0.997; 95% CI, 0.991-1.003 for women vs OR, 0.990; 95% CI, 0.985-0.994 for men). Unfavorable outcomes and in-hospital deaths decreased in both sexes. In intracerebral hemorrhage, favorable outcomes decreased in both sexes, and unfavorable outcomes and deaths decreased only in women. In subarachnoid hemorrhage, the proportion of favorable outcomes was unchanged, and that of unfavorable outcomes and deaths decreased in both sexes. Conclusions and Relevance In this study, functional outcomes improved in patients with ischemic stroke during the past 20 years in both sexes presumably partly owing to the development of acute reperfusion therapy. The outcomes of patients with hemorrhagic stroke did not clearly improve in the same period.

Abstract
Background To clarify differences in clinical significance of intracardiac thrombi in nonvalvular atrial fibrillation‐associated stroke as identified by transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE). Methods and Results Using patient data on nonvalvular atrial fibrillation‐associated ischemic stroke between 2011 and 2014 from 15 South Korean stroke centers (n=4841) and 18 Japanese centers (n=1192), implementation rates of TEE/TTE, and detection rates of intracardiac thrombi at each center were correlated. The primary outcome was recurrent ischemic stroke at 1 year after the onset. A total of 5648 patients (median age, 75 years; 2650 women) were analyzed. Intracardiac thrombi were detected in 75 patients (1.3%) overall. Thrombi were detected in 7.8% of patients with TEE (either TEE alone or TEE+TTE: n=679) and in 0.6% of those with TTE alone (n=3572). Thrombus detection rates varied between 0% and 14.3% among centers. As TEE implementation rates at each center increased from 0% to 56.7%, thrombus detection rates increased linearly (detection rate [%]=0.11×TEE rate [%]+1.09 [linear regression], P<0.01). TTE implementation rates (32.3%–100%) were not associated with thrombus detection rates (P=0.53). Intracardiac thrombi were associated with risk of recurrent ischemic stroke overall (adjusted hazard ratio [aHR] 2.35, 95% CI, 1.07–5.16). Thrombus‐associated ischemic stroke risk was high in patients with TEE (aHR, 3.13; 95% CI, 1.17–8.35), but not in those with TTE alone (aHR, 0.89; 95% CI, 0.12–6.51). Conclusions Our data suggest clinical relevance of TEE for accurate detection and risk stratification of intracardiac thrombi in nonvalvular atrial fibrillation‐associated stroke.

Abstract
Aim: We evaluated the delay in stroke reperfusion therapy between the pre-coronavirus disease 2019 (COVID-19) period and the with-COVID-19 period, and compared this delay between each phase of the with-COVID-19 period.
Methods: Patients with acute ischemic stroke (AIS) undergoing intravenous thrombolysis and/or mechanical thrombectomy were selected from our single-center prospective registry. The time to perform reperfusion therapy were compared between patients admitted from March 2019 to February 2020 (pre-COVID-19 group) and those from March 2020 to February 2021 (with-COVID-19 group). Patients in the with-COVID-19 group were further divided into three 4-month-long subgroups (first-phase: March to June 2020; second-phase: July to October 2020; third-phase: November 2020 to February 2021), and the time delay of reperfusion therapy were compared between these subgroups.
Results: Of 1,260 patients with AIS hospitalized in the study period, 265 patients were examined. Compared with the pre-COVID-19 group (133 patients; median age, 79 years), the with-COVID-19 group (132 patients; median age, 79 years) had a longer median door-to-imaging time (25 min vs. 27 min,P=0.04), and a longer door-to-groin puncture time (65 min vs. 72 min,P=0.02). In the three 4-month-long subgroups, the median door-to-needle time (49 min, 43 min, and 38 min, respectively;P=0.04) and door-to-groin puncture time (83 min, 70 min, and 61 min,P<0.01, respectively) decreased significantly during the with-COVID-19 period.
Conclusions: The delay in reperfusion therapy increased during the with-COVID-19 period compared with
the pre-COVID-19 period. However, the door-to-needle time and door-to-groin puncture time decreased as time elapsed during the
with-COVID-19 period. ClinicalTrials.gov Identifier: NCT02251665

Abstract
Background and purpose The impact of the paraoxonase-1 (PON1) polymorphism, Q192R, on platelet inhibition in response to clopidogrel remains controversial. We aimed to investigate the association between carrier status of PON1 Q192R and high platelet reactivity (HPR) with clopidogrel in patients undergoing elective neurointervention. Methods Post-clopidogrel platelet reactivity was measured using a VerifyNow® P2Y12 assay in P2Y12 reaction units (PRU) for consecutive patients before the treatment. Genotype testing was performed for PON1 Q192R and CYP2C19*2 and *3 (no function alleles), and *17. PRU was corrected on the basis of hematocrit. We investigated associations between factors including carrying ≥1 PON1 192R allele and HPR defined as original and corrected PRU ≥208. Results Of 475 patients (232 men, median age, 68 years), HPR by original and corrected PRU was observed in 259 and 199 patients (54.5% and 41.9%), respectively. Carriers of ≥1 PON1 192R allele more frequently had HPR by original and corrected PRU compared with non-carriers (91.5% vs 85.2%, P = 0.031 and 92.5% vs 85.9%, P = 0.026, respectively). In multivariate analyses, carrying ≥1 PON1 192R allele was associated with HPR by original (odds ratio [OR] 1.96, 95% confidence interval [CI] 1.03–3.76) and corrected PRU (OR 2.34, 95% CI 1.21–4.74) after adjustment for age, sex, treatment with antihypertensive medications, hematocrit, platelet count, total cholesterol, and carrying ≥1 CYP2C19 no function allele. Conclusions Carrying ≥1 PON1 192R allele is associated with HPR by original and corrected PRU with clopidogrel in patients undergoing elective neurointervention, although alternative results related to other genetic polymorphisms cannot be excluded.

Abstract
Aims: The relationship between left ventricular (LV) function and AF detection in embolic stroke of undetermined source (ESUS) patients with insertable cardiac monitors (ICMs) remains unclear. We investigated the association between LV function and AF detection in patients with ESUS after ICMs implantation.
Methods: We enrolled patients with ESUS who underwent ICMs implantation from September 2016 to September 2020 using a single-center, prospective registry. LV systolic and diastolic functions were assessed on precordial echocardiography by LV fractional shortening (LVFS) and average E/e’, respectively. Associations between characteristics of LV function and detection of AF by ICMs were analyzed.
Results: Participants comprised 101 patients (median age, 74 years; male, 62%). During a median follow-up period of 442 days (interquartile range (IQR), 202–770 days), AF was detected in 24 patients (24%). Median duration from ICMs implantation to AF detection was 71 days (IQR, 13–150 days). When LVFS and E/e’ were dichotomized by cutoff value, each of low LVFS (<35.5%; adjusted hazard ratio (HR), 4.77; 95% confidence interval (CI), 1.77–12.9) and high E/e’ (≥ 8.65; adjusted HR, 4.56; 95%CI, 1.17–17.7) were independently associated with AF detection after adjusting for age and sex. When patients were divided into four groups according to dichotomized LVFS and E/e’, the combination of low LVFS and high E/e’ was independently associated with AF.
Conclusions: In patients with ESUS after ICMs implantation, the LV characteristics of low LVFS and high E/e’ were associated with AF detection.

Abstract
Background Outcomes after mechanical thrombectomy (MT) for large vessel occlusion (LVO) were compared between stroke patients anticoagulated with direct oral anticoagulants (DOACs) and those anticoagulated with warfarin. MATERIALS AND METHODS From data for 2399 LVO stroke patients in a prospective, multicenter registry, patients with prior oral anticoagulation who underwent MT were analyzed. Angiographic outcomes included successful recanalization (modified Thrombolysis in Cerebral Infarction 2b/3). Clinical outcomes included modified Rankin Scale (mRS) score 0-2 at 3 months and symptomatic intracranial hemorrhage. RESULTS A total of 235 patients (95 women, median age 78 [interquartile range, 72-84] years) were included. Prescribed anticoagulants were DOACs in 61 patients and warfarin in 174 patients. Of patients on warfarin, 135 (77.6%) had a non-therapeutic therapy (international normalized ration [INR] ≤1.7). Patients on therapeutic warfarin (INR >1.7) had younger age and shorter onset to hospital arrival time than those on non-therapeutic warfarin and DOACs. The achievement of successful recanalization in warfarin groups was similar to the DOACs group, with an adjusted odds ratio (aOR) for therapeutic warfarin versus DOACs of 1.14 (95% confidence interval [CI], 0.27-4.89) and non-therapeutic warfarin versus DOACs of 0.92 (95% CI, 0.39-2.20), respectively. The frequency of mRS score 0-2 at 3 months in the therapeutic (aOR, 2.63; 95% CI, 0.86-7.98) and non-therapeutic warfarin (aOR, 1.77; 95% CI, 0.76-4.09) groups were similar to those in the DOACs group. There was no significant difference in symptomatic intracranial hemorrhage between groups. CONCLUSIONS Angiographic and clinical outcomes after MT were similar between patients anticoagulated with DOACs and warfarin.

Introduction: The correlation between the composition of thrombi retrieved by mechanical thrombectomy (MT) and stroke etiology is inconclusive. We describe a case with atherosclerotic components in thrombi retrieved by MT for acute internal carotid artery (ICA) occlusion. Case Presentation: A 69-year-old man with acute onset of global aphasia and right hemiplegia was transferred to our institute. His baseline National Institutes of Health Stroke Scale score was 24. Magnetic resonance imaging demonstrated acute ischemic stroke in the left parietal lobe. Magnetic resonance angiography revealed occlusion of the left ICA. MT was attempted for acute left ICA occlusion. The initial angiography showed occlusion of the proximal ICA, while intraprocedural angiography revealed a large thrombus that extended from the cervical ICA to the intracranial ICA. Successful reperfusion was achieved by five passes using stent retrievers and an aspiration catheter. A large volume of red thrombus was retrieved by each pass. The final angiogram showed successful reperfusion with modified Thrombolysis in Cerebral Ischemia grade 2b and severe stenosis in the proximal ICA. Neck magnetic resonance imaging showed severe left ICA stenosis with a vulnerable plaque. Hence, his stroke etiology was determined as large artery atherosclerosis. Histopathological examination of the retrieved thrombi revealed atheromatous components, including cholesterol clefts, foam cells, and a necrotic core. Conclusions: Atherosclerotic components in retrieved thrombi might provide useful clues for diagnosing stroke pathogenesis. Further studies are warranted to clarify the utility of assessing atheromatous components in retrieved thrombi in diagnosing stroke etiology.

Abstract
Introduction: The usefulness of the blind exchange with mini-pinning (BEMP) technique has recently been reported for mechanical thrombectomy in patients with stroke owing to medium vessel occlusion (MeVO). The Tron stent retriever can be delivered and deployed through a 0.0165-inch microcatheter. This retriever has potential as an effective and safe treatment for acute ischemic stroke (AIS) due to occlusion of the M2 segment of the middle cerebral artery (MCA). Here, we report the outcomes of the BEMP technique using Tron stent retrievers for M2 occlusion thrombectomy. Methods: Consecutive patients with AIS owing to M2 occlusion who underwent the BEMP technique using 2 × 15-mm or 4 × 20-mm Tron stent retrievers were included. The technique involves deploying a Tron stent retriever through a 0.0165-inch microcatheter, followed by microcatheter removal and blind navigation of a 3MAX or 4MAX aspiration catheter over the bare Tron delivery wire until the aspiration catheter reaches the clot. A Tron stent retriever is inserted into the aspiration catheter like a cork and subsequently pulled as a unit. We assessed procedural outcomes [first-pass expanded thrombolysis in cerebral infarction (eTICI) score 2c/3 and 2b/2c/3], safety outcomes [symptomatic intracranial hemorrhage (sICH)], and clinical outcomes (good outcome rate defined as modified Rankin Scale score 0–2 at 90 days and mortality at 90 days). Results: Eighteen M2 vessels were treated in 15 patients (six female, median age: 80 years, and median National Institutes of Health Stroke Scale score: 18). The BEMP technique was performed successfully in all cases. Whether to use a 3MAX or 4MAX catheter was determined by considering one of the following target vessels: dominant, non-dominant, or co-dominant M2 (3MAX, n = 9; 4MAX, n = 9). The first-pass eTICI 2c/3 and 2b/2c/3 rates were 47 (7/15) and 60% (9/15), respectively; sICH was not observed. Seven patients (47%) achieved good outcomes, and one patient (7%) died within 90 days. Conclusions: The Tron stent retriever was safely and effectively used in the BEMP technique for acute MCA M2 occlusion and can be combined with a 0.0165-inch microcatheter, which may be useful for treating MeVO, in general.

Abstract
Introduction: The pandemic of coronavirus disease 2019 (COVID-19) has had a significant impact on stroke healthcare, including the prehospital care system and in-hospital workflow. Japan experienced the outbreak of COVID-19, and the State of Emergency was declared during April 2020 and May 2020. The aim of the present study was to clarify the effect of the COVID-19 pandemic on a comprehensive stroke center in Japan. Methods: We retrospectively reviewed consecutive patients with acute ischemic stroke admitted in our institute between December 2019 and July 2020. The patients who underwent reperfusion therapy (intravenous thrombolysis and/or mechanical thrombectomy) were divided into the pre-COVID-19 period (December 2019 to March 2020) and the With-COVID-19 period (April 2020 to July 2020). Study outcomes were the number of stroke admissions in our institute, workflow time metrics, the frequency of modified Rankin Scale score 0–2 at discharge, and brain imaging modalities before reperfusion therapy in patients who underwent reperfusion therapy. Results: In our institute, the number of stroke admissions decreased during the State of Emergency and then increased after the lifting of the State of Emergency. Among patients who underwent reperfusion therapy (median age, 77 years; female 27%; median baseline National Institutes of Health Stroke Scale score, 10), times from hospital arrival to imaging [25 (21–33) min vs. 30 (25–38) min, P = 0.03] and to thrombolysis [38 (31–52) min vs. 51 (37–64) min, P = 0.03] were prolonged compared with the pre-COVID-19 period. There was no significant difference in the frequency of modified Rankin Scale score 0–2 at discharge between the two periods (32 vs. 45%, P = 0.21). The proportion of computed tomography vs. magnetic resonance imaging as an emergency brain imaging tool before reperfusion therapy changed, with computed tomography having become predominant in the With-COVID-19 period. Conclusions: In our institute, the number of stroke admissions, workflow time metrics, and imaging modalities for reperfusion therapy were affected by the COVID-19 pandemic.

Abstract
BACKGROUND We aimed to identify the large ischemic core (LIC) volume ranges in acute ischemic stroke patients that can benefit from mechanical thrombectomy (MT). METHODS Consecutive patients within 24 hours of onset of anterior circulation ischemic stroke with large vessel occlusion and ischemic core volumes of 70-300 mL were included from our single-center prospective database from March 2014 to December 2019. Subjects were divided into three groups by baseline ischemic core volume (A: 70-100 mL; B: 101-130 mL; C: >130 mL). We compared modified Rankin Scale (mRS) score 0-2 at 3 months and parenchymal hematoma between patients receiving MT and standard medical treatment (SMT), and determined clinically treatable core volume ranges for MT. RESULTS Of 157 patients (86 women; median age, 81 years; median ischemic core volume, 123 mL), 49 patients underwent MT. In Group A (n=52), MT patients (n=31) showed a higher proportion of mRS 0-2 at 3 months (52% vs 5%, P<0.05) versus SMT, respectively. Group B (n=36) MT patients (n=14) also had a higher proportion of mRS 0-2 at 3 months (29% vs 9%, P=0.13) versus SMT, respectively. In Group C (n=69), only four patients received MT. The 95% confidence intervals for the probability of mRS 0-2 at 3 months in patients with MT (n=49) versus SMT (n=108) intersected at 120-130 mL. CONCLUSIONS Ischemic core volumes between 70 and 100 mL may benefit from MT. The treatable upper core limit is approximately 120 mL in selected patients with LIC of 70-300 mL.

Abstract
Background and Purpose: To determine whether acute major-vessel occlusion (MVO) predicts atrial fibrillation (AF) in cryptogenic stroke (CS) patients, we analyzed the association between acute MVO and AF detected by insertable cardiac monitoring (ICM). Methods: We conducted a retrospective, multicenter, observational study of patients with CS who underwent ICM implantation between October 2016 and March 2018. In this analysis, we included follow-up data until June 2018. We analyzed the association of MVO with AF detected by ICM. Results: We included 84 consecutive patients with CS who underwent ICM implantation. The proportion of patients with newly detected AF by ICM was higher in patients with MVO than in those without (41% [12/29] vs. 13% [7/55], p < 0.01) within 90 days of ICM implantation. The MVO was associated with AF after adjustment for each clinically relevant factor. Conclusions: MVO was independently associated with AF detection in patients with CS, which suggests that MVO may be a useful predictor of latent AF. It is therefore essential to actively assess latent AF in patients with CS presenting with MVO.

Abstract
Aim:
This study aimed to investigate the diagnostic yield of 7-day Holter monitoring for detecting covert atrial fibrillation (AF) in patients with recent embolic stroke of undetermined source (ESUS) and to identify the pre-entry screening biomarkers that had significant associations with later detection of AF (clinicaltrials.gov. NCT02801708).
Methods:
A total of 206 patients who have recent ESUS without previously documented AF underwent Holter electrocardiography using a chest strap-style monitor. External validation of biomarkers predictive of AF was performed using 83 patients with ESUS who were implanted with insertable cardiac monitors.
Results:
The 7-day Holter monitoring started at a median of 13 days after the onset of stroke. AF was detected in 14 patients, and three of these showed a single AF episode lasting <2 min. The median time delay to the first documented AF was 50 h. Each of serum brain natriuretic peptide ≥ 66.0 pg/mL (adjusted odds ratio 5.23), atrial premature contractions (APCs) ≥ 345 beats (3.80), and APC short runs ≥ 13 (5.74) on 24-h Holter prior to the 7-day Holter showed a significant association with detection of AF, independent of age and physiological findings in this derivation cohort, and all of these showed a significant association in the validation cohort (adjusted odds ratio 6.59, 7.87, and 6.16, respectively).
Conclusions:
In recent ESUS patients, the detection rate of AF using the 7-day Holter monitoring was 6.8% (95% CI 4.1%–11.1%). Brain natriuretic peptide, APC count, and APC short runs in the standard clinical workup seemed to be predictors of covert AF.

Abstract
Objective Internal carotid artery (ICA) dissection is known to cause binary types of stroke, cerebral infarction, and subarachnoid hemorrhage (SAH). However, it is rare that these two pathologies take place in a clinical scenario. We report a case of ICA dissection with ischemic onset, which was followed by SAH on the same day during diagnostic angiography. Case Presentation A 60-year-old woman with chronic hypertension rapidly developed right hemiplegia. She had been suffering from slight headache and abnormal sensation in the right limbs 1 week before the ictus. MRI demonstrated small acute infarctions in the left middle cerebral artery (MCA) territory. The left ICA was not visualized on MRA. Diffusion-perfusion mismatch was indicated by the automated image postprocessing system. Endovascular recanalization was planned to prevent the progression of cerebral infarction. After advancing a 5MAX ACE, initial left ICA angiography was performed, resulting in extravasation of contrast medium from the C2 segment of the left ICA. 3D rotational angiography revealed left ICA dissection of the C2 segment. To secure hemostasis, the patient underwent internal trapping at the C1 and C2 segments of the left ICA. Collateral flow to the left MCA via an anterior communicating artery was observed. On day 28, the patient was transferred to a rehabilitation hospital with right hemiplegia and motor aphasia. Conclusion In cases of tandem lesions with preceding neurological symptoms, ICA dissection should be considered as one of the causes. Careful injection of contrast medium may be necessary if ICA dissection is strongly suspected.

Abstract
BACKGROUND Patients with vascular Ehlers-Danlos syndrome (EDS) occasionally suffer from arterial dissection. Eagle syndrome, which is caused by an elongated styloid process and also causes arterial dissection, is difficult to diagnose and could sometimes be overlooked. Little is known of the coexistence of these two diseases, and treatment strategy is not established. Here, we present a case of bilateral internal carotid artery (ICA) dissection due to Eagle syndrome in a patient with vascular EDS. CASE PRESENTATION A 30-year-old man was admitted to our hospital because of sudden onset of mild sensory disturbance in his left limbs. He had a history of Ehlers-Danlos syndrome (EDS) and also had left cervical internal carotid artery (ICA) dissection 3 years before. Diffusion-weighted imaging showed acute cerebral infarcts in the right hemisphere. Cervical computed tomography angiography (CTA) revealed the right ICA narrowing at the cervical portion in addition to the previous left cervical ICA dissection. Cervical magnetic resonance imaging (MRI) revealed double-lumen and intramural hematoma at the narrowing portion of the right cervical ICA, which indicates arterial dissection. CT also revealed bilateral elongated styloid processes which are close to each side of cervical ICA. We diagnosed him as bilateral ICA dissection due to bilateral Eagle syndrome. Considering vascular complications due to vascular EDS, we performed closer follow-up with transoral carotid ultrasonography (TOCU). In 4 months, his right ICA dissection gradually improved without stroke recurrence or deterioration of dissection. CONCLUSIONS Since patients with vascular EDS easily develop arterial dissection, Eagle syndrome may be overlooked. Clinicians should consider Eagle syndrome in the case of vascular EDS with extracranial ICA dissection and close follow-up should be prioritized in cases of Eagle syndrome with vascular EDS.

Abstract
Scleromyxedema (SME) is characterized by widespread waxy papules on the skin, with mucin deposits in the upper dermis. Twenty-one SME cases of myopathy have been reported; of the cases, six showed vacuolar formation, and two showed mucin deposition. We report the first case of SME with mucin-associated vacuolated fibers. A 45-year-old woman with SME developed progressive proximal muscle weakness. Muscle biopsy revealed myopathic changes with numerous vacuoles linked to mucin in the affected muscle fibers, which were heavily immunostained for fibroblast growth factor 2 (FGF2). Despite repeated high dose oral prednisolone and intravenous immunoglobulin administrations, muscle weakness recurred continuingly, culminating in death due to congestive heart failure. Immunotherapy was partly effective in our case, although it was refractory. Treatment responsiveness in patients with SME myopathy varied; however, due to its rarity, the mechanism remains to be elucidated. To address this issue, we investigated muscle specimens immunohistochemically and detected marked upregulation of FGF2 in the affected muscle fibers of our patient. FGF2, a strong myogenesis inhibitor, may exert a suppressive effect on muscle fiber regeneration, which may have conferred refractoriness to our patient's SME myopathy.

Abstract
BACKGROUND Patency of the middle cerebral artery (MCA) in acute ischemic stroke with internal carotid artery (ICA) occlusions is associated with less severe stroke and favorable outcomes. However, thrombus migration to distal intracranial vessels may lead to unfavorable outcomes. We investigated the influence of thrombus migration on clinical outcomes in patients with ICA occlusions and patent MCA. MATERIALS AND METHODS We retrospectively analyzed patients with acute ischemic stroke compromising ICA occlusions and patent MCA who were consecutively admitted to our hospital between January 2006 and March 2016. Thrombus migration was assessed (1) by analyzing the discrepancies in arterial occlusion sites between initial imaging and follow-up imaging and (2) by analyzing how occlusion sites changed during endovascular therapy. RESULTS Thirty-eight patients (mean age: 74.9 years; 23 men, 15 women, median National Institutes of Health Stroke Scale score = 7.5) with ICA occlusions and patent MCA were ultimately included. We identified 10 patients (26%) with thrombus migration (spontaneous: 3; during endovascular therapy: 7). Patients with thrombus migration had higher rates of unfavorable functional outcomes (modified Rankin Scale scores 3-6 at 90 days) than those without thrombus migration (90% vs. 39%, p < .01). Multivariate analysis showed that thrombus migration was independently related to unfavorable functional outcomes (odds ratio, 42.9; 95% confidence interval, 1.5-1211.0; p = .03). CONCLUSION Thrombus migration in cases of ICA occlusion with patent MCA is associated with poor prognosis. Careful monitoring is required under these conditions even if the initial clinical presentation is mild.

Abstract
OBJECTIVE To determine whether frequent premature atrial contractions (PAC) predict atrial fibrillation (AF) in cryptogenic stroke patients, we analyzed the association between frequent PACs in 24-h Holter electrocardiogram recording and AF detected by insertable cardiac monitoring (ICM). METHODS We retrospectively analyzed a database of 66 consecutive patients with cryptogenic stroke who received ICM implantation between October 2016 and March 2018 at 5 stroke centers. We included the follow-up data until June 2018 in this analysis. We defined frequent PACs as the upper quartile of the 66 patients. We analyzed the association of frequent PACs with AF detected by ICM. RESULTS Frequent PACs were defined as >222 PACs per a 24-h period. The proportion of patients with newly detected AF by ICM was higher in patients with frequent PACs than those without (50% [8/16] vs. 22% [11/50], p < 0.05). Frequent PACs were associated with AF detection and time to the first AF after adjustment for CHADS2 score after index stroke, high plasma -B-type natriuretic peptide (BNP; >100 pg/mL) or serum -N-terminal pro-BNP levels (>300 pg/mL), and large left atrial diameter (≥45 mm). CONCLUSION High frequency of PACs in cryptogenic stroke may be a strong predictor of AF detected by ICM.

Abstract
Background and purpose:
There are risks of recurrent stroke and systemic embolism during the early period after mechanical thrombectomy (MT) especially in patients with hemorrhagic transformation because of delayed initiation of anticoagulants. We assessed the rate of early recurrent embolism (ERE) after MT and the effect of intracranial hemorrhage on ERE.
Methods:
Patients who underwent MT for acute ischemic stroke in our institution between January 2014 and July 2019 were retrospectively reviewed. ERE was defined as symptomatic recurrent stroke and systemic embolism within 14 days after MT. A multivariable logistic regression model with prespecified covariates including anticoagulants within 48 hours after MT was constructed to determine the association between ERE and parenchymal hemorrhage (PH) within 36 hours (SITS-MOST definition). Adjustment for differences in baseline characteristics between patients with and without PH was performed using the inverse probability of treatment weighting (IPTW).
Results:
A total of 300 patients (mean age, 75.4 years; female patients, 49%; median baseline National Institutes of Health Stroke Scale score, 18 [IQR, 12-25]) were included. ERE was observed in 12 of 300 patients (8 strokes and 4 systemic embolisms; 4.0%; 95% confidence interval [CI], 2.3 to 9.3). The median time from MT to ERE was 6.5 days (IQR, 3-8) and no ERE occurred before PH. Patients with PH were not likely to be initiated anticoagulants within 48 hours after MT (41 % vs. 77%,
p
< 0.01). In multivariable analysis, PH was significantly associated with an increased risk of ERE (unweighted odds ratio, 5.61; 95% CI, 1.25 to 25.27,
p
= 0.025). After weighting for IPTW, PH remained an independent predictor of ERE (weighted odds ratio 6.20, 95% CI, 1.05 to 36.57,
p
= 0.044).
Conclusions:
ERE occurred in about 4% of patients after the MT. Our results reveal a dilemma that intracranial hemorrhage after reperfusion therapy may increase the risk of recurrent embolism.

Abstract
Background: To maximize the effect of intravenous (IV) thrombolysis and/or endovascular therapy (EVT) for acute ischemic stroke (AIS), stroke centers need to establish a parallel workflow on the basis of a code stroke (CS) protocol. At Kokura Memorial Hospital (KMH), we implemented a CS system in January 2014; however, the process of information sharing within the team has occasionally been burdensome. Objective: To solve this problem using information communication technology (ICT), we developed a novel application for smart devices, named “Task Calc. Stroke” (TCS), and aimed to investigate the impact of TCS on AIS care. Methods: TCS can visualize the real-time progress of crucial tasks for AIS on a dashboard by changing color indicators. From August 2015 to March 2017, we installed TCS at KMH and recommended its use during normal business hours (NBH). We compared the door-to-computed tomography time, the door-to-complete blood count (door-to-CBC) time, the door-to-needle for IV thrombolysis time, and the door-to-puncture for EVT time among three treatment groups, one using TCS (“TCS-based CS”), one not using TCS (“phone-based CS”), and one not based on CS (“non-CS”). A questionnaire survey regarding communication problems was conducted among the CS teams at 3 months after the implementation of TCS. Results: During the study period, 74 patients with AIS were transported to KMH within 4.5 h from onset during NBH, and 53 were treated using a CS approach (phone-based CS: 26, TSC-based CS: 27). The door-to-CBC time was significantly reduced in the TCS-based CS group compared to the phone-based CS group, from 31 to 19 min (p = 0.043). Other processing times were also reduced, albeit not significantly. The rate of IV thrombosis was higher in the TCS-based CS group (78% vs. 46%, p = 0.037). The questionnaire was correctly filled in by 34/38 (89%) respondents, and 82% of the respondents felt a reduction in communication burden by using the TCS application. Conclusions: TCS is a novel approach that uses ICT to support information sharing in a parallel CS workflow in AIS care. It shortens the processing times of critical tasks and lessens the communication burden among team members.

Abstract
A significant number of patients with minor or mild stroke symptoms on initial presentation subsequently develop neurological deterioration and poor clinical outcomes at hospital discharge. The presence of an underlying large vessel occlusion is a strong predictor of both clinical worsening and poor outcome. Although patients with a low baseline National Institutes of Health Stroke Scale (NIHSS) could have been included in some randomized controlled trials, the benefits of the mechanical thrombectomy for patients with a low NIHSS score are unknown. The causes of neurological deterioration in patients with underlying large vessel occlusion are heterogeneous, but include collateral failure, and no straightforward mechanisms are found in the majority of cases. Patients with internal carotid artery occlusion, but with a patent middle cerebral artery (MCA), can occasionally have good collateral circulation and develop only minor or mild stroke. These patients exhibit collateral MCA flow via the circle of Willis despite ipsilateral internal carotid artery occlusion. However, thrombus migration may cause occlusion of collateral MCA flow, leading to dramatic neurological deterioration. Careful observation and detailed assessment are required for the management of these patients. Recent studies have examined the efficacy and optimal timing of thrombolysis or mechanical thrombectomy for patients with minor or mild stroke. Herein, we review the mechanisms of neurological deterioration, and the efficacy of reperfusion therapy, for patients with minor or mild stroke.
