European Stroke Organisation guideline on endarterectomy and stenting for carotid artery stenosis

European Stroke Journal, 2021
Atherosclerotic stenosis of the internal carotid artery is an important cause of stroke. The aim of this guideline is to analyse the evidence pertaining to medical, surgical and endovascular treatment of patients with carotid stenosis.

Beneficial effect of carotid endarterectomy in symptomatic patients with high-grade carotid stenosis.

New England Journal of Medicine, 1991
BACKGROUND Without strong evidence of benefit, the use of carotid endarterectomy for prophylaxis against stroke rose dramatically until the mid-1980s, then declined. Our investigation sought to determine whether carotid endarterectomy reduces the risk of

Large-Eddy simulation of pulsatile blood flow [PDF]

, 2009
Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall.

A Recurrent CNN for Automatic Detection and Classification of Coronary Artery Plaque and Stenosis in Coronary CT Angiography [PDF]

IEEE Transactions on Medical Imaging, 2018
Various types of atherosclerotic plaque and varying grades of stenosis could lead to different management of patients with a coronary artery disease. Therefore, it is crucial to detect and classify the type of coronary artery plaque, as well as to detect
