Background and Purpose- The benefit of endovascular therapy in extended time windows has been demonstrated in patients with anterior circulation large vessel occlusion ischemic stroke and favorable imaging profile. We evaluated whether collaterals and thrombus burden influence the associations between revascularization, time-to-treatment, and outcome in endovascular therapy-treated patients with basilar artery occlusion. Methods- We retrospectively analyzed clinical and imaging data of consecutive endovascular therapy-treated patients with basilar artery occlusion included in the multicenter Basilar Artery Treatment and Management Collaboration. ⋯ In logistic regression analysis (adjusted for age, National Institutes of Health Stroke Scale, and time-to-treatment ≤6/>6 hours), revascularization was associated with good outcome in patients with favorable BATMAN score (odds ratio, 15.8; 95% CI, 1.4-175; P=0.02) or PC-CS (odds ratio, 9.4; 95% CI, 1.4-64; P=0.02). In patients who achieved revascularization, early (time-to-treatment ≤6 hours) but not late treatment was associated with improved outcome in patients with unfavorable BATMAN score (18/52 [35%]; odds ratio, 15; 95% CI, 1.9-124; P=0.01) or PC-CS (16/44 [36%]; odds ratio, 5.5; 95% CI, 1.4-21; P=0.01). Conclusions- Revascularization is associated with good outcome in patients with basilar artery occlusion with good collaterals and less extensive occlusion, even >6 hours after onset.

Background and Purpose- Predicting malignant middle cerebral artery (MCA) infarction can help to identify patients who may benefit from preventive decompressive surgery. We aimed to investigate the association between the ratio of intracranial cerebrospinal fluid (CSF) volume to intracranial volume (ICV) and malignant MCA infarction. Methods- Patients with an occlusion proximal to the M3 segment of the MCA were selected from the DUST (Dutch Acute Stroke Study). ⋯ CSF/ICV was independently associated with malignant MCA infarction in 3 multivariable models: (1) with age and admission National Institutes of Health Stroke Scale (odds ratio, 3.3; 95% CI, 1.1-11.1), (2) with admission National Institutes of Health Stroke Scale and poor collateral score (odds ratio, 7.0; 95% CI, 2.6-21.3), and (3) with terminal internal carotid artery or proximal M1 occlusion and poor collateral score (odds ratio, 7.7; 95% CI, 2.8-23.9). The performance of model 1 (areas under the receiver operating characteristic curves, 0.795 versus 0.824; P=0.033), model 2 (areas under the receiver operating characteristic curves, 0.813 versus 0.850; P<0.001), and model 3 (areas under the receiver operating characteristic curves, 0.811 versus 0.856; P<0.001) improved significantly after adding CSF/ICV. Conclusions- The CSF/ICV ratio is associated with malignant MCA infarction and has added value to clinical and imaging prediction models in limited numbers of patients.

Background and Purpose- Evidence on the natural history of hemorrhagic moyamoya disease is still insufficient. We investigated the incidence of recurrent intracranial bleeding, mortality, and risk factors for rebleeding in patients with moyamoya disease. Methods- A total of 128 conservatively managed patients with hemorrhagic presentation and complete follow-up data were included. ⋯ Conclusions- Rebleeding events were common and the main cause of death in patients with hemorrhagic moyamoya disease. The risk of rebleeding steadily increased during long-term follow-up. Smoking was a risk factor for rebleeding, and hypertension was associated with increased mortality.

Randomized Controlled Trial Multicenter Study
Rapid Neurologic Improvement Predicts Favorable Outcome 90 Days After Thrombectomy in the DEFUSE 3 Study.
Background and Purpose- Thrombectomy in late time windows leads to improved outcomes in patients with ischemic stroke due to large vessel occlusion. We determined whether patients with rapid neurological improvement (RNI) 24 hours after thrombectomy were more likely to have a favorable clinical outcome in the DEFUSE 3 study (Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke 3). Methods- All patients who underwent thrombectomy in DEFUSE 3 were included. ⋯ RNI was a favorable prognostic sign following late-window thrombectomy in DEFUSE 3. Clinical Trial Registration- URL: https://www.clinicaltrials.gov. Unique identifier: NCT02586415.

Background and Purpose- We sought to evaluate the available literature to determine whether primary seizure prevention with antiepileptic drugs reduces the risk of poor outcomes and clinically relevant seizures among adult patients with spontaneous intracerebral hemorrhage. Methods- Meta-analysis of observational studies and randomized controlled trials evaluating the use of any antiepileptic drug for primary seizure prevention among adult (≥18 years) patients with spontaneous intracerebral hemorrhage. The primary end point was poor clinical outcome at the longest recorded follow-up, defined as either a high (>3) modified Rankin Scale score or all-cause mortality during follow-up if the modified Rankin Scale score was not recorded. ⋯ Overall, the use of antiepileptic drugs was not associated with a high Rankin Scale or all-cause mortality (odds ratio: 0.99; 95% CI, 0.66-1.49) or incident seizures (odds ratio: 0.89; 95% CI, 0.52-1.51) at the longest recorded follow-up time. Conclusions- The use of antiepileptic drugs as primary prevention among adult patients with spontaneous intracerebral hemorrhage is not associated with improved neurological function during long-term follow-up. Future studies should focus on the preventive use of distinct antiepileptic agents among patients at high risk of both seizures and poor outcomes.
