Background This study evaluated the performance of the newer-generation Emboguard Balloon Guide Catheter (EBGC) in treating anterior circulation large vessel occlusions (LVOs). Methods A prospectively ...

Results The analysis included 18 330 patients readmitted within 90 days post-MT, with 63.7% readmitted to index hospitals and 36.3% to non-index hospitals. Readmission to the index hospital was not ...

Background Aneurysm wall enhancement (AWE) on vessel wall imaging (VWI) scans is a robust biomarker for aneurysmal vulnerability. This study aimed to explore the association of different sleep ...

Background Whether rescue intracranial stenting (RIS) should be performed in patients with vertebrobasilar occlusions (VBO) refractory to endovascular mechanical thrombectomy (MT) remains an open ...

Objective To improve early diagnosis of patients who have basilar artery occlusion (BAO) and to provide evidence for treatment decisions based on clinical characteristics, treatment strategies, and ...

Background Studies suggest head positioning may impact cerebral venous outflow by creating dynamic stenosis in the internal jugular veins (IJVs) in susceptible individuals. Objective To examine the ...

Background Predicting the final infarct after an extended time window mechanical thrombectomy (MT) is beneficial for treatment planning in acute ischemic stroke (AIS). By introducing guidance from ...

Cerebral arteriovenous malformations (AVMs) are an uncommon type of central nervous system vascular anomaly that have the potential to rupture and cause intracranial hemorrhage. AVM hemorrhagic risk ...

Background and purpose Collateral blood flow to the affected cerebral territory in acute ischemic stroke may modify the effect of intravenous alteplase treatment (IVT) prior to endovascular treatment ...

Background A critical evaluation of the US Food and Drug Administration (FDA) recommendation to avoid intracranial stent placement (ICAS) within 7 days of a qualifying cerebral ischemic event. Methods ...

Results 134 patients were enrolled from 10 stroke centers. The primary endpoint was reached in 97 patients (81.5%, 95% CI 74.5% to 88.5%). In patients who failed the primary endpoint, TICI 2b/3 was ...
