High Middle Cerebral Artery Wall Shear Stress in Branch Atheromatous Disease: A Computational Fluid Dynamics Analysis.
J Atheroscler Thromb
January 2025
Department of Neurology, National Cerebral and Cardiovascular Center.
Aim: Branch atheromatous disease (BAD), characterized by the occlusion of perforating branches near the orifice of a parent artery, often develops early neurological deterioration because the mechanisms underlying BAD remain unclear. Abnormal wall shear stress (WSS) is strongly associated with endothelial dysfunction and plaque growth or rupture. Therefore, we hypothesized that computational fluid dynamics (CFD) modeling could detect differences in WSS between BAD and small-vessel occlusion (SVO), both of which result from perforating artery occlusion/stenosis.

Background: Adjacent bony structures may directly rub the carotid artery during swallowing or head and/neck movement. Long-term repeated stimulation might be considered to be a potential risk factor for carotid atherosclerotic plaque formation, development, and hazard. we defined the process as "Osteal Kneading".

Acute retinal ischemia, including central retinal artery occlusion (CRAO), is recognized as a stroke equivalent by the American Heart Association/American Stroke Association (AHA/ASA), necessitating immediate multidisciplinary evaluation and management. However, referral patterns among ophthalmologists remain inconsistent, and evidence-based therapeutic interventions to improve visual outcomes are currently lacking. CRAO is associated with a significantly elevated risk of subsequent acute ischemic stroke (AIS), particularly within the first week following diagnosis, yet the role of intravenous thrombolysis (IVT) in this setting remains controversial.

We report a case of persistent consciousness disturbance due to non-convulsive status epilepticus (NCSE) following a successful mechanical thrombectomy (MT). A 98-year-old female with atrial fibrillation presented with impaired consciousness and right hemiparesis 6 hrs after her last known well state. Magnetic resonance angiography revealed occlusion of the left internal carotid artery, necessitating MT to achieve complete recanalisation.

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.
