Intracranial atherosclerotic disease and resultant intracranial stenosis is a global leading cause of stroke, and poses an ongoing treatment challenge. Among patients with intracranial stenosis, those with hemodynamic compromise are at high risk for recurrent stroke despite medical therapy and risk factor modification. Revascularization of the hypoperfused territory is the most plausible treatment strategy for these high-risk patients, yet surgical and endovascular therapies have not yet shown to be sufficiently safe and effective in randomized controlled trials. Advances in diagnostic and therapeutic technologies have led to a resurgence of interest in surgical and endovascular treatment strategies, with a growing body of evidence to support their further evaluation in the treatment of select patient populations. This review outlines the current and emerging endovascular and surgical treatments and highlights promising future management strategies.

Design and early progress of the Comparison of Anticoagulation and anti-Platelet Therapies for Intracranial Vascular Atherostenosis (CAPTIVA) trial.
Int J Stroke

Medical University of South Carolina, Charleston, SC, USA.
Background: The usual antithrombotic treatment for symptomatic intracranial atherosclerotic stenosis (ICAS) consists of dual treatment with clopidogrel and aspirin for 90 days followed by aspirin alone but the risk of recurrent stroke remains high up to 12 months. The Comparison of Anticoagulation and anti-Platelet Therapies for Intracranial Vascular Atherostenosis (CAPTIVA) trial was designed to determine whether other combinations of dual antithrombotic therapy are superior to clopidogrel and aspirin.
Methods: CAPTIVA is an ongoing, prospective, double-blinded, three-arm clinical trial at over 100 sites in the United States and Canada that will randomize 1683 high-risk subjects with a symptomatic infarct attributed to 70-99% stenosis of a major intracranial artery to 12 months of treatment with (1) ticagrelor (180 mg loading dose, then 90 mg twice daily), (2) low-dose rivaroxaban (2.
Exploring in Ischemic Stroke and Moyamoya Disease: From Cellular Models to Clinical Insights.

Advances in stroke genetics have highlighted the critical role of rare genetic variants in cerebrovascular diseases, with emerging as a key player in ischemic stroke and Moyamoya disease (MMD). Initially identified as the primary susceptibility gene for MMD, -notably the p.R4810K variant-has been strongly linked to intracranial artery stenosis (ICAS) and various ischemic stroke subtypes, particularly in East Asian populations.

Department of Neurology, Shandong Provincial Hospital, Shandong University, Jinan, Shandong, China.
Objectives: To investigate the association of metabolic status newly defined or obesity with asymptomatic intracranial arterial stenosis (aICAS) among populations in rural China.
Methods: The cross-sectional study is based on the Rose asymptomatic IntraCranial Artery Stenosis (RICAS) cohort, which enrolled 2005 participants aged 40 years or older without a history of clinical stroke or transient ischemic attack. Metabolically healthy status (MH) was defined by a newly proposed criterion: (1) systolic blood pressure (SBP) < 130 mmHg and without antihypertensive medication; (2) a waist-to-hip ratio (WHR) below 1.
Shunt Dependency Syndrome Combined with Sinus Stenosis after Cyst-peritoneal Shunting of Arachnoid Cyst: A 20-year Rare Complication.

Department of Neurology, The Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.
Shunt dependence syndrome is a serious long-term complication characterized by symptoms and signs of increased intracranial pressure with normal-sized lateral ventricles after several years of arachnoid cyst-peritoneal shunting. It is easy to misdiagnose and overlook when combined with sinus stenosis, thus delaying treatment. Here, we present a 35-year-old man with an unexplained headache and binocular horizontal diplopia with high intracranial pressure.

Acute internal carotid artery occlusion (AICAO) can result in malignant cerebral edema and unfavorable patient outcomes. This study evaluated the utility of transcranial Doppler (TCD) in assessing contralateral flow compensation and predicting outcomes in patients with AICAO. We enrolled 51 patients within 6 h of symptom onset and conducted TCD examinations to evaluate collateral circulation.
