This study presents the case of a brain-injured patient whose pathological awakening after coma and absence of interaction led to a diagnosis of lack of consciousness when standard clinical scales were administered. However, we were able to demonstrate conscious perception in this patient from initial clinical assessments using the Motor Behaviour...

Background Emerging yet contrasting evidence from animal and human studies associates ischemic preconditioning with improvement of subsequent stroke severity, although long‐term outcome remains unclear. The purpose of this study was to analyze how preceding cerebral ischemic events influence subsequent stroke severity and outcome. Methods and Resu...

Introduction Systemic contraceptives increase the risk of ischemic stroke but little is known about the characteristics, mechanisms and long-term outcome post stroke of patients on hormonal contraception. We sought to To assess characteristics and outcome of acute ischemic stroke (AIS) in young women using systemic hormonal contraceptives (SHC) and...
Article
The majority of patients with Coronavirus disease 2019 (COVID-19) present mild to moderate illness and recover without hospitalization. Nevertheless, 5 % of cases require hospitalization in the intensive care unit, with 15 % of them showing severe central and peripheral nervous system manifestations. These patients should be considered high risk pa...
Article
Background Cervical artery dissection is a major cause of stroke in young people (aged <50 years). Historically, clinicians have preferred using oral anticoagulation with vitamin K antagonists for patients with cervical artery dissection, although some current guidelines—based on available evidence from mostly observational studies—suggest using as...

Cervical and transcranial Doppler (TCD) are widely used as non-invasive methods in the evaluation of acute ischemic stroke (AIS) patients. High-grade carotid artery stenosis induces haemodynamic changes such as collateral flow and a so-called post-stenotic flow pattern of the middle cerebral artery (MCA), which appears flattened, with a reduction o...
Article
Background and purpose: Computed tomographic perfusion (CTP) is useful in diagnosis of patients with transient focal neurological symptoms. In acute imaging of patients with a suspected transient ischemic attack (TIA), it remains unclear which patients develop focal perfusion abnormalities (FPA), that is, hypoperfusion or hyperperfusion. We aimed...

Background : Transcranial doppler (TCD) is widely used on acute ischemic stroke (AIS) patients. Pulsatility index (PI) is a rheological TCD parameter used in clinical assessment of intracranial hypertension and vascular recanalization. We studied the influence of precerebral stenoses and other variables on middle cerebral artery (MCA) PI in anterio...

Background and Objective Introduction Patients with diabetes may develop early cerebrovascular disease manifesting as a higher burden of atherosclerosis Hypothesis In an acute stroke population, we hypothesise significantly different neurosonological precerebral vessel characteristics between diabetics and non-diabetics. Methods We retrospectively...
Article
Secondary pseudotumor cerebri syndrome (SPCS) is defined as intracranial hypertension caused by factors other than an underlying infectious, malignant, or macroscopic structural brain lesion.¹ We report a case of exercise-induced SPCS due to decompensation of borderline venous return following bilateral jugular vein (JV) obstruction treated with ju...
Article
Introduction: Preconditioning improves acute ischemic stroke (AIS) outcomes in animals and possibly in humans. The influence of a preceding ischemic event (PIE), such as a TIA or AIS occurring at different intervals, sites and for different durations, needs to be studied in humans. Hypothesis: We aimed to identify whether a PIE can have a precondit...
Article
Background: Hairdresser-related ischemic cerebrovascular events (HICE) are attributed to compression of vertebral arteries or cervical artery dissections. We determined their frequency, mechanisms, localization and outcome in a pre-specified study. Methods: We prospectively collected ischemic strokes and transient ischemic attacks occurring in r...
Article

Medial temporal lobe abnormalities on DWI and functional imaging are occasionally observed in patients with transient global amnesia. We used CTP to study these patients during or briefly after resolution of their amnesic syndrome. From 2002 onward, patients satisfying clinical criteria for transient global amnesia who underwent CTP were included....
Article
BACKGROUND/AIMS: Portal vein embolization (PVE) is an accepted procedure, which, by redirecting portal vein flow toward specific hepatic segments, is able to pre-operatively increase the volume of the future liver remnant (FLR). The consequent reduction of liver dysfunction risk enables to extend the number of pa tients eligible for major hepatic...
