The Massachusetts General Hospital Neuroradiology Division employed an experience and evidence based approach to develop a neuroimaging algorithm to best select patients with severe ischemic strokes ...

Background and purpose Large vessel occlusion (LVO) is a major cause of acute ischemic stroke (AIS). Identifying its underlying etiology, particularly intracranial atherosclerotic stenosis (ICAS), is ...

Background The impact of parent artery stenosis on the treatment of intracranial aneurysms by using flow diversion (FD) remains unknown. This multicenter retrospective study aimed to evaluate the ...

Background Blood urea/creatinine (U/Cr) ratio is considered to be an ideal biomarker of dehydration. We investigated the association between the U/Cr ratio trajectory and delayed cerebral ischemia ...

Paediatric neurointervention (PNI) markedly differs from adult neuro-intervention, requiring highly subspecialized clinical skills, knowledge, and techniques. Minimum standards of practice are well ...

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 ...

Endovascular recanalization of non-acute intracranial occlusion in the setting of recurrent stroke is a frontier of neurointervention that has not been well explored. Careful consideration and ...

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 The cumulative impact of radiation dose reduction strategies in acute hospital settings remains underreported. This study quantifies and compares cumulative radiation exposure in patients ...

Background Although recently presented randomized trials have failed to prove an overall benefit of mechanical thrombectomy (MT) for patients with medium vessel occlusions (MeVOs), questions remain ...

Background Endovascular treatment (EVT) failures and early reocclusions in stroke often result from arterial wall disease, incomplete thrombus withdrawal, or acute endothelial injury. Intracranial and ...

Background The ability to differentiate intracranial atherosclerotic disease (ICAD) related large vessel occlusion (LVO) from embolism is critical for stroke management. We hypothesized that the ...
