BACKGROUND AND PURPOSE: In patients with large vessel occlusions, endovascular treatment (ET) has been shown to be superior to intravenous thrombolysis (IVT) in recent trials. However, the effectiveness of ET in elderly patients is uncertain. METHODS: Using our stroke database, we compared the rates of good outcome (modified Rankin scale (mRS) ≤2), excellent outcome (mRS 0-1), poor outcome (mRS 5-6) at discharge, in-hospital death, infarct size, and symptomatic intracranial hemorrhage (SICH) in patients aged ≥80 years with distal intracranial carotid artery, M1 and M2 occlusions during two time periods...

The optimal treatment for patients with chronic symptomatic middle cerebral artery (MCA) total occlusion is not well established. In addition to medical therapy, vessel recanalisation with stenting has shown much promise, especially for patients with recurrent ischemic symptoms. Nevertheless, the incidence of symptomatic in-stent restenosis (ISR) is high, and is associated with an unfavorable prognosis. Drug coated balloons (DCBs) have been proven to be effective in treating and preventing ISR. However, the feasibility of DCBs for de novo intracranial atherothrombotic stenosis has not been previously described, especially for total occlusion lesions...

OBJECTIVE The role of venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH) is not well understood. The aim of this systematic review is to attempt to identify subsets of patients with IIH who will benefit from VSS based on the pressure gradients of their venous sinus stenosis. METHODS MEDLINE/PubMed was searched for studies reporting venous pressure gradients across the stenotic segment of the venous sinus, pre- and post-stent pressure gradients, and clinical outcomes after VSS. Findings are reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines...

BACKGROUND: Dual antiplatelet therapy (DAPT) associating aspirin + clopidogrel is commonly utilized in neurovascular interventions despite unpredictable clopidogrel efficacy with 4% to 50% of patients considered nonresponders. Ticagrelor is an antiplatelet agent with low resistance rates but unknown efficacy and safety in neurovascular patients. OBJECTIVE: To evaluate frequency of ischemic and hemorrhagic events in patients treated with aspirin and ticagrelor when associated with perioperative heparin bolus for unruptured aneurysms treated with intracranial stents...

Acute thrombotic occlusions of the large vessels, such as internal carotid artery, arms and legs arteries, and intracranial vessels, frequently require multiple techniques such as selective thrombolysis, manual aspiration, and stent retrievers for mechanical thrombectomy with combination of the mentioned techniques. Because of the massive thrombotic burden associated with these conditions, the response to systemic intravenous thrombolysis is poor. We present a case of a successful massive thrombi aspiration in a single attempt using an 8Fr guide catheter with aspiration syringe, subsequent ipsilateral middle cerebral artery mechanical thrombectomy, and axillary artery clot disruption attempt in a patient with acute ischemic stroke, right arm critical ischemia, and persistent atrial fibrillation...
