Positional transient loss of consciousness and hemispheric deficits in the setting of severe four-vessel extracranial cerebrovascular disease

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
Carotid artery stenosis typically causes hemispheric neurologic effects by atheroembolism. Nonhemispheric symptoms, such as syncope, are generally not attributable to extracranial carotid disease.

Beyond Venous Inflammation: Vessel Wall Imaging of Intracranial Arteries in Neuro‐Behçet's Syndrome

European Journal of Neurology, Volume 33, Issue 8, August 2026.
ABSTRACT Background Neuro‐Behçet syndrome (NBS) is a heterogeneous inflammatory disorder in which venous involvement is well recognized, while intracranial arterial pathology remains insufficiently characterized. Conventional luminal imaging methods are limited in detecting early or isolated arterial wall abnormalities.

A Loop That Matters—An Unusual Case of Bow Hunter’s Syndrome

Brain Sciences, 2022
Bow Hunter’s syndrome (BHS), also known as rotational vertebral artery occlusion (VAO), is a rare entity in which vertebral artery is reversibly compressed due to rotation or extension of the head, causing vertebrobasilar insufficiency.

Long QT Syndrome Type 5 With Coexisting KCNE1 and RYR2 Variants: A Diagnostic Ambiguity

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Long QT syndrome (LQTS) predisposes to syncope and sudden cardiac death. Type 5 LQTS, linked to KCNE1 variants, is rare. A teenage female presented with recurrent syncope. ECG showed QTc 485 ms. Genetic testing identified KCNE1 and RYR2 variants. Beta‐blockers and ICD prevented events.

Osseous Variants of the Cervical Spine with Potential Pathological Significance: Possible Evidence of Vertebrobasilar Insufficiency in a Skeletal Sample from the Post-Classical Cemetery of Corfinio (12th–15th Centuries CE, L’Aquila, Italy)

Heritage
The vertebral arteries supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of the brain. These arteries are susceptible to deformation from external factors such as muscular, ligamentous, or bony structures, and any ...

The Epidemiology and Clinical Presentation of the Acute Imbalance Syndrome (AIS)—A Systematic Review and Meta‐Analysis

European Journal of Neurology, Volume 33, Issue 6, June 2026.
ABSTRACT Objectives The acute imbalance syndrome (AIS) refers to acute‐onset and persistent vertigo, dizziness and/or imbalance without nystagmus, reflecting a subset of the acute vestibular syndrome (AVS) with or without nystagmus. While AVS with nystagmus is well characterized and the approach to these patients is validated, much less is known about ...

Juvenile Bow Hunter's Stroke without Hemodynamic Changes

Clinical Medicine Insights: Case Reports, 2010
Bow hunter's stroke (BHS) is a cerebrovascular disease caused by occlusion of the vertebral artery (VA) on head rotation. BHS is generally associated with hemodynamic changes, often leading to vertebrobasilar insufficiency symptoms, such as vertigo and ...

Tenecteplase Versus Alteplase for First‐Pass Reperfusion in Basilar Artery Occlusion Stroke Thrombectomy

Annals of Neurology, Volume 99, Issue 3, Page 692-704, March 2026.
Objective The first‐pass effect (FPE), defined as excellent reperfusion after a single attempt, is associated with improved outcomes in large vessel occlusion stroke. We evaluated whether intravenous tenecteplase (TNK) compared with alteplase (TPA) increases the likelihood of FPE in basilar artery occlusion (BAO).
