Background: Acute intracranial occlusion of the internal carotid artery (ICA) can be distinguished into (a) occlusion of the terminal ICA, involving the proximal segments of the middle or anterior cerebral artery (ICA-L/-T) and (b) non-terminal intracranial occlusions of the ICA with patent circle of Willis (ICA-I). While patients with ICA-L/-T occlusion were included in all randomized controlled trials on endovascular therapy (EVT) in anterior large vessel occlusion, data on EVT in ICA-I occlusion is scarce. We thus aimed to evaluate effectiveness and safety of EVT in ICA-I occlusions in comparison to ICA-L/-T occlusions. Methods: A large international multicentre cohort was searched for patients with intracranial ICA occlusion treated with EVT between 2014 and 2023. Patients were stratified by ICA occlusion pattern, differentiating ICA-I and ICA-L/-T occlusions. Baseline factors, technical (modified thrombolysis in cerebral infarction (mTICI) scale) and functional outcomes (modified Rankin scale [mRS] at 3 months) as well as rates of (symptomatic) intracranial hemorrhage ([s]ICH) were analyzed. Results: Of 13,453 patients, 1825 (13.6%) had isolated ICA occlusion. ICA-occlusion pattern was ICA-I in 559 (4.2%) and ICA-L/-T in 1266 (9.4%) patients. Age (years: 74 vs 73), sex (female: 45.8% vs 49.0%) and pre-stroke functional independency (pre-mRS ⩽ 2: 89.9% vs 92.2%) did not differ between the groups. Stroke severity was lower in ICA-I patients (NIHSS at admission: 14 [7–19] vs 17 [13–21] points). EVT was similarly successful with respect to technical (mTICI2b/3: 76.1% (ICA-I) vs 76.6% (ICA-L/-T); aOR 1.01 [0.76–1.35]) and functional outcome (mRS ordinal shift cOR 1.01 [0.83–1.23] in adjusted analyses. Rates of ICH (18.9% vs 34.5%; aOR 0.47 [0.36–0.62] and sICH (4.7% vs 7.3%; aOR 0.58 [0.35–0.97] were lower in ICA-I patients. Conclusion: EVT might be performed safely and similarly successful in patients with ICA-I occlusions as in patients with ICA-L/-T occlusions. © European Stroke Organisation 2024.

(Figure presented.) © European Stroke Organisation 2024.; Background and aims: Previous observational data indicate that young adults treated with intravenous thrombolysis (IVT) for acute ischemic stroke have more favorable outcomes and less complications when compared to older adults. Given the limited data on this topic, we aimed to provide more evidence on clinical outcomes and safety in such patients, using a large international thrombolysis registry. Methods: In this prospective multicenter study, we used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry from 1998 to 2020. Patients who received endovascular treatment (EVT), as only treatment or in addition to IVT, were not included in this cohort. Using multivariable regression models, we compared thrombolysed young patients aged 18–49 years with those aged ⩾50 years with regards to the following outcomes: favorable outcome in stroke survivors (modified Rankin Scale ⩽2), symptomatic intracranial hemorrhage (sICH) according to European Cooperative Acute Stroke Study II (ECASS II) criteria, and three-months all-cause death. Results: Of the 16,651 IVT treated patients, 1346 (8.1%) were 18–49 years. Young adults in TRISP were more often male (59.6% vs 54.0%), had a lower median NIHSS score on admission, 7 (4–13) versus 8 (5–15), and had less cardiovascular risk factors except for smoking (42.0% vs 19.0%) when compared to older patients. When compared to thrombolysed patients aged ⩾50 years, a favorable functional outcome was more likely in young adults: 81.9% versus 56.4%, aOR 2.30 (1.80–2.95), whilst sICH 1.6% versus 4.6%, aOR 0.45 (0.23–0.90) and death 2.3% versus 14.2%, aOR 0.21 (0.11–0.39) were less likely. Conclusions: Intravenous thrombolysis in young adults is independently associated with higher rates of favorable outcomes and lower rates of complications. © European Stroke Organisation 2024.

Purpose:Mowat-Wilson syndrome (MWS) is a genetic disease characterized by distinctive facial features, moderate to severe intellectual disability, and congenital malformations, including Hirschsprung disease, genital and eye anomalies, and congenital heart defects, caused by haploinsufficiency of the ZEB2 gene. To date, no characteristic pattern of brain dysmorphology in MWS has been defined.Methods:Through brain magnetic resonance imaging (MRI) analysis, we delineated a neuroimaging phenotype in 54 MWS patients with a proven ZEB2 defect, compared it with the features identified in a thorough review of published cases, and evaluated genotype-phenotype correlations.Results:Ninety-six percent of patients had abnormal MRI results. The most common features were anomalies of corpus callosum (79.6% of cases), hippocampal abnormalities (77.8%), enlargement of cerebral ventricles (68.5%), and white matter abnormalities (reduction of thickness 40.7%, localized signal alterations 22.2%). Other consistent findings were large basal ganglia, cortical, and cerebellar malformations. Most features were underrepresented in the literature. We also found ZEB2 variations leading to synthesis of a defective protein to be favorable for psychomotor development and some epilepsy features but also associated with corpus callosum agenesis.Conclusion:This study delineated the spectrum of brain anomalies in MWS and provided new insights into the role of ZEB2 in neurodevelopment. © 2016 American College of Medical Genetics and Genomics.

Background and Purpose This study aimed to investigate the effect of endovascular treatment (EVT, with or without intravenous thrombolysis [IVT]) versus IVT alone on outcomes in patients with acute ischemic stroke (AIS) and intracranial large vessel occlusion (LVO) attributable to cervical artery dissection (CeAD). Methods This multinational cohort study was conducted based on prospectively collected data from the EVA-TRISP (EndoVAscular treatment and ThRombolysis for Ischemic Stroke Patients) collaboration. Consecutive patients (2015–2019) with AIS-LVO attributable to CeAD treated with EVT and/or IVT were included. Primary outcome measures were (1) favorable 3-month outcome (modified Rankin Scale score 0–2) and (2) complete recanalization (thrombolysis in cerebral infarction scale 2b/3). Odds ratios with 95% confidence intervals (OR [95% CI]) from logistic regression models were calculated (unadjusted, adjusted). Secondary analyses were performed in the patients with LVO in the anterior circulation (LVOant) including propensity score matching. Results Among 290 patients, 222 (76.6%) had EVT and 68 (23.4%) IVT alone. EVT-treated patients had more severe strokes (National Institutes of Health Stroke Scale score, median [interquartile range]: 14 [10–19] vs. 4 [2–7], P<0.001). The frequency of favorable 3-month outcome did not differ significantly between both groups (EVT: 64.0% vs. IVT: 86.8%; ORadjusted 0.56 [0.24–1.32]). EVT was associated with higher rates of recanalization (80.5% vs. 40.7%; ORadjusted 8.85 [4.28–18.29]) compared to IVT. All secondary analyses showed higher recanalization rates in the EVT-group, which however never translated into better functional outcome rates compared to the IVT-group. Conclusion We observed no signal of superiority of EVT over IVT regarding functional outcome in CeAD-patients with AIS and LVO despite higher rates of complete recanalization with EVT. Whether pathophysiological CeAD-characteristics or their younger age might explain this observation deserves further research. © 2023 Korean Stroke Society.
