Purpose We sought to determine the diagnostic agreement between the revised ultrasonography approach by the German Society of Ultrasound in Medicine (DEGUM) and the established Society of Radiologists in Ultrasound (SRU) consensus criteria for the grading of carotid artery disease. Materials and methods Post-hoc analysis of a prospective multicenter study, in which patients underwent ultrasonography and digital subtraction angiography (DSA) of carotid arteries for validation of the DEGUM approac...

Infection with the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) leads to a previously unknown clinical picture, which is known as COVID-19 (COrona VIrus Disease-2019) and was first described in the Hubei region of China. The SARS-CoV-2 pandemic has implications for all areas of medicine. It directly and indirectly affects the care of neurological diseases. SARS-CoV-2 infection may be associated with an increased incidence of neurological manifestations such as encephalopathy ...

Purpose The German Society of Ultrasound in Medicine (DEGUM) recently revised its multiparametric criteria for duplex ultrasonography (DUS) grading of internal carotid artery (ICA) disease. We determined the diagnostic accuracy of the revised DEGUM criteria for ultrasonography grading of ICA disease in a prospective multicenter study. Materials and Methods We evaluated consecutive patients who underwent digital subtraction angiography of the extracranial carotid arteries at four tertiary care ho...

RationaleOptimal secondary prevention of embolic stroke of undetermined source is not established. The current standard in these patients is acetylsalicylic acid, despite high prevalence of yet undetected paroxysmal atrial fibrillation.AimThe ATTICUS randomized trial is designed to determine whether the factor Xa inhibitor apixaban administered within 7 days after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of new ischemic lesions documented by brain...

Aims Variability in responsiveness to clopidogrel is a clinical problem in secondary prevention after cerebral ischaemia which has been suggested to be linked to competitive metabolization of clopidogrel and cytochrome P450 (CYP) 3A4-oxidated statins such as simvastatin. We assessed the hypothesis that simvastatin, in contrast to CYP 2C9-metabolized fluvastatin, reduces clopidogrel-mediated platelet inhibition. Methods We performed a randomized, double-blind, double-dummy, two period crossover s...

BACKGROUND: In secondary prevention after ischemic stroke variability in individual responsiveness to clopidogrel is a clinically relevant problem. Among possible mechanisms that may contribute to this phenomenon, clopidogrel-statin interactions are discussed. Particularly, competitive metabolization of lipohilic statins (i.e. simvastatin) and clopidogrel by cytochrome P450 (CYP) 3A4 was suggested to reduce the inhibitory effect of clopidogrel on platelet aggregation. In contrast, hydrophilic fl...
