Contemporary prevalence of carotid stenosis in patients presenting with ischaemic stroke

British Journal of Surgery, 2019
Carotid stenosis is a common cause of ischaemic stroke and transient ischaemic attack (TIA). Despite rising recognition and centralization of stroke services there has been a decline in interventions for carotid stenosis in recent years.

Secondary recurrent carotid stenosis [PDF]

Journal of Vascular Surgery, 1996
Recurrent carotid stenosis after carotid endarterectomy has been extensively reported. The occurrence, however, of another ipsilateral restenosis that requires a third carotid operation is rare. The purpose of this study was to evaluate possible risk factors and the most efficacious management of the patient with "secondary" recurrent carotid stenosis ...

Randomized Trial of Stent versus Surgery for Asymptomatic Carotid Stenosis.

New England Journal of Medicine, 2016
BACKGROUND Previous clinical trials have suggested that carotid-artery stenting with a device to capture and remove emboli ("embolic protection") is an effective alternative to carotid endarterectomy in patients at average or high risk for surgical ...

Inflated 3D Convolution-Transformer for Weakly-supervised Carotid Stenosis Grading with Ultrasound Videos [PDF]

arXiv, 2023
Localization of the narrowest position of the vessel and corresponding vessel and remnant vessel delineation in carotid ultrasound (US) are essential for carotid stenosis grading (CSG) in clinical practice. However, the pipeline is time-consuming and tough due to the ambiguous boundaries of plaque and temporal variation. To automatize this procedure, a

Management of patients with carotid stenosis [PDF]

Pathophysiology of Haemostasis and Thrombosis, 2002
Carotid atherosclerosis is one of the main risk factors for ischemic stroke. The annual risk of ipsilateral stroke for asymptomatic, albeit severe stenoses is as low as 1 to 2%, but increases to 13% in patients with recent ischemic symptoms. However the risk decreases after the first 2-3 years from the symptomatic episode, dropping to 3%.

Carotid artery stenosis

BMJ, 2010
Carotid endarterectomy is currently the most effective intervention to prevent stroke in patients with recent symptoms of carotid stenosis.1 2 It also prevents future stroke in younger patients (under 75 years) who have not yet had symptoms, as long as the risk of stroke and death from surgery is not more than 3% Patients naturally prefer carotid ...

Area-preserving mapping of 3D ultrasound carotid artery images using density-equalizing reference map [PDF]

IEEE Transactions on Biomedical Engineering, 67(9), 1507-1517 (2020), 2018
Carotid atherosclerosis is a focal disease at the bifurcations of the carotid artery. To quantitatively monitor the local changes in the vessel-wall-plus-plaque thickness (VWT) and compare the VWT distributions for different patients or for the same patients at different ultrasound scanning sessions, a mapping technique is required to adjust for the ...

Stratification of carotid atheromatous plaque using interpretable deep learning methods on B-mode ultrasound images [PDF]

, 2022
Carotid atherosclerosis is the major cause of ischemic stroke resulting in significant rates of mortality and disability annually. Early diagnosis of such cases is of great importance, since it enables clinicians to apply a more effective treatment strategy. This paper introduces an interpretable classification approach of carotid ultrasound images for

Carotid revascularization and medical management for asymptomatic carotid stenosis: Protocol of the CREST-2 clinical trials

International Journal of Stroke, 2017
Rationale Trials conducted decades ago demonstrated that carotid endarterectomy by skilled surgeons reduced stroke risk in asymptomatic patients. Developments in carotid stenting and improvements in medical prevention of stroke caused by atherothrombotic

Ophthalmic artery flow direction change predicts recurrence of ischemic stroke after carotid stenting: a longitudinal observational study

European Journal of Medical Research, 2023
Background and purpose The implantation of carotid artery stents prevents recurrent ischemic stroke in patients with carotid stenosis. This study aimed to investigate associations between change of ophthalmic artery flow (COAF) post carotid stenting and ...
