Importance: The addition of direct thrombin inhibitors or glycoprotein platelet inhibitors to intravenous thrombolysis in patients undergoing endovascular thrombectomy for acute ischemic stroke may improve reperfusion rates and clinical outcomes.
Objective: To investigate the safety and efficacy of these agents.
Design, Setting, And Participants: This was a preplanned cohort analysis from the Multi-Arm Optimization of Stroke Thrombolysis (MOST) randomized clinical trial, which lasted from 2019 to 2023 with a 90-day follow-up.
The surgical or endovascular treatment of patients with asymptomatic atherosclerotic carotid artery stenosis has become controversial, given the advances in medical treatment since the original pivotal trials establishing efficacy for surgical endarterectomy. The ECST-2 (European Carotid Stenosis Trial-2) recently reported no benefit of revascularization procedures over modern medical treatment alone. In addition, its findings extend to lower-risk symptomatic patients.

Methods: A post hoc analysis of medically treated patients enrolled in the CMOSS trial (Carotid or Middle Cerebral Artery Occlusion Surgery Study; URL: https://www.clinicaltrials.
Background: Obtaining timely informed consent is a key barrier in acute ischemic stroke clinical trial recruitment. Electronic consent (eConsent) allows electronic delivery and documentation of the informed consent process, which may optimize recruitment. eConsent in acute ischemic stroke clinical trials, however, is limited and understudied.

To minimize variability, structured tools like the Rankin Focused Assessment and central adjudication are recommended. This study compares local versus centrally adjudicated mRS scores in the MOST trial (Multi-Arm Optimization of Stroke Thrombolysis).
View Article and Find Full Text PDFBackground: Whether the long-term benefit of stroke prevention when stenting is added to medical therapy (MT) over MT alone for symptomatic severe intracranial artery stenosis offsets the perioperative risks of the stenting has not been directly evaluated in a randomized trial. We aimed to compare the long-term (>3 years) effect of stenting versus MT alone in patients with symptomatic severe intracranial artery stenosis in a randomized trial.
Methods: We extended the follow-up of 358 subjects enrolled in a multicenter, open-label, randomized trial conducted at 8 centers in China.
Background And Purpose: Whether differences in stenosis degree affect treatment selection in patients with intracranial artery atherosclerotic stenosis (ICAS) still remains unclear. This study explores the impact of stenosis degree on outcomes of stent placement compared with medical therapy alone in patients with symptomatic intracranial artery stenosis.
Materials And Methods: Patients with a TIA or nondisabling ischemic stroke, attributed to 70%-99% stenosis of a major intracranial artery, were included.
Background: Underlying intracranial stenosis is the most common cause of failed mechanical thrombectomy in patients with acute ischemic stroke with large vessel occlusion. Adjunct emergent stenting is sometimes performed to improve or maintain reperfusion, despite limited data regarding its safety or efficacy.
Methods: We conducted a prospective multicenter observational international cohort study.

Background And Objectives: First-line therapy for most intracranial dural arteriovenous fistulas (dAVFs) is endovascular embolization, but some require microsurgical ligation due to limited endovascular accessibility, anticipated lower cure rates, or unacceptable risk profiles. We investigated the most common surgically treated dAVF locations and the approaches and outcomes of each.
Methods: The Consortium for Dural Arteriovenous Fistula Outcomes Research database was retrospectively reviewed.
Background: The efficacy of percutaneous transluminal angioplasty and stenting (PTAS) relative to medical management in treating symptomatic intracranial arterial stenosis (ICAS) varies based on the qualifying artery. This study aims to evaluate PTAS compared with medical therapy alone in cases of ICAS involving the internal carotid artery (ICA), middle cerebral artery (MCA), vertebral artery (VA) and basilar artery (BA).
Methods: This study involves a thorough pooled analysis of individual patient data from two randomised controlled trials, evaluating the efficacy of PTAS in comparison to medical management for symptomatic ICAS with different qualifying arteries.
Background: Intravenous thrombolysis is a standard treatment of acute ischemic stroke. The efficacy and safety of combining intravenous thrombolysis with argatroban (an anticoagulant agent) or eptifibatide (an antiplatelet agent) are unclear.
Methods: We conducted a phase 3, three-group, adaptive, single-blind, randomized, controlled clinical trial at 57 sites in the United States.
Background: Whether the safety and efficacy of percutaneous transluminal angioplasty and stenting (PTAS) is significantly different from that of medical treatment alone for symptomatic intracranial arterial stenosis (ICAS) is debatable. A study was undertaken to determine the safety and efficacy of both treatments for symptomatic ICAS.
Methods: This preplanned pooled individual patient data analysis included 400 participants treated with PTAS and 409 treated with medical treatment alone in two large multicenter randomized clinical trials (SAMMPRIS and CASSISS).
Ischemic stroke can arise from the sudden occlusion of a brain-feeding artery by a clot (embolic), or local thrombosis. Hemodynamic stroke occurs when blood flow does not sufficiently meet the metabolic demand of a brain region at a certain time. This discrepancy between demand and supply can occur with cerebropetal arterial occlusion or high-grade stenosis but also arises with systemic conditions reducing blood pressure.

Conversion is the rare transformation of a low-grade dAVF to a higher grade. Factors associated with increased risk of dAVF conversion to a higher grade are poorly understood.
View Article and Find Full Text PDFBackground: Transcarotid artery revascularization (TCAR) is an interventional therapy for symptomatic internal carotid artery disease. Currently, the utilization of TCAR is contentious due to limited evidence. In this study, we evaluate the safety and efficacy of TCAR in patients with symptomatic internal carotid artery disease compared with carotid endarterectomy (CEA) and carotid artery stenting (CAS).
View Article and Find Full Text PDFThis comprehensive literature review focuses on acute stroke related to intracranial atherosclerotic stenosis (ICAS), with an emphasis on ICAS-large vessel occlusion. ICAS is the leading cause of stroke globally, with high recurrence risk, especially in Asian, Black, and Hispanic populations. Various risk factors, including hypertension, diabetes, hyperlipidemia, smoking, and advanced age lead to ICAS, which in turn results in stroke through different mechanisms.
View Article and Find Full Text PDFImportance: Prior trials of extracranial-intracranial (EC-IC) bypass surgery showed no benefit for stroke prevention in patients with atherosclerotic occlusion of the internal carotid artery (ICA) or middle cerebral artery (MCA), but there have been subsequent improvements in surgical techniques and patient selection.
Objective: To evaluate EC-IC bypass surgery in symptomatic patients with atherosclerotic occlusion of the ICA or MCA, using refined patient and operator selection.
Design, Setting, And Participants: This was a randomized, open-label, outcome assessor-blinded trial conducted at 13 centers in China.
Objective: Despite the adoption of same-day outpatient surgical procedures in some specialties, it remains common practice to admit patients for monitoring after elective endovascular treatment of brain aneurysms to monitor for complications. The necessity of such monitoring has not been fully characterized. Here, the authors reviewed the utilization of imaging during posttreatment hospitalization, a surrogate measure for workup of suspected complications requiring hospital resources, to infer the value of inpatient monitoring after endovascular aneurysm treatment.

Introduction: Intracranial atherosclerotic stenosis (ICAS) is a common cause of stroke worldwide. However, whether the treatment options for symptomatic ICAS is stent placement or medical therapy alone is still controversial. At present, three multicentre randomised controlled trials (RCTs) have been published, but their research designs are also slightly different and the conclusions are not completely consistent.
