Safety and efficacy of sequential intra-arterial and intravenous administration of tirofiban during the periprocedural period of stenting in perforator-rich intracranial arteries

Background Tirofiban is widely used in ischemic stroke, but its safety and efficacy during stenting of perforator-rich intracranial arteries are unclear. We speculate that prophylactic use of an intra ...

Use of CT perfusion to select patients with medium and distal vessel occlusions for thrombectomy: multicenter retrospective analysis

Background Early infarct growth rate (EIGR) provides a dynamic view of stroke progression. Use of CT perfusion (CTP) and EIGR has been thoroughly studied in large vessel occlusions, but not in distal ...

Reinitiating anticoagulation in chronic subdural hematomas: does adding middle meningeal artery embolization add value? A multi-institutional, multinational database study

Background The safety of early anticoagulation in chronic subdural hematoma (cSDH) patients treated with surgery, with or without middle meningeal artery embolization (MMAE), remains unclear. This ...

Salvage endovascular treatment for intracranial restenosis

Background Endovascular treatment (EVT) is an important treatment for symptomatic intracranial atherosclerotic stenosis (sICAS). However, restenosis limits its long-term efficacy, and some patients ...

Artificial intelligence-assisted middle meningeal artery embolization for chronic subdural hematoma with overlay visualization

The effectiveness of middle meningeal artery (MMA) embolization for chronic subdural hematoma is well established,1–3 and distal and multibranch penetration of embolic agents is recognized as a key ...

Outcomes of combined mechanical thrombectomy versus stent retriever or contact aspiration in acute ischemic stroke: an updated network meta-analysis

Background For large vessel occlusion (LVO) ischemic strokes, three major techniques of mechanical thrombectomy (MT) have demonstrated efficacy. Here we compare the safety and efficacy of stent ...

Intracranial pressure is affected by head rotation: effect of dynamic jugular stenosis on lumbar puncture opening pressure

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 ...

Occlusion site and outcomes in intra-arterial tenecteplase after successful endovascular therapy: a secondary analysis of the ANGEL-TNK trial

Background Endovascular thrombectomy achieves macroreperfusion in large vessel occlusion (LVO) stroke, but only one-quarter of patients had excellent functional outcome. Adjunct intra-arterial (IA) ...

Short-term safety of dual versus single antiplatelet therapy in flow diversion for distal intracranial aneurysms: results from the DART trial

Background and purpose Flow diverters (FDs) have become one of the primary treatments for intracranial aneurysms (IAs). However, their use in distal IA has been associated with higher complication ...
