  2. 11. Symptomatic Carotid Stenosis - optimal timing of surgical treatment

    Author : Sofia Strömberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid endarterectomy; carotid artery stenosis; stroke; transient ischemic attack; ocular transient ischemic attack;

    Abstract : Abstract In patients with symptomatic carotid artery stenosis is convincing evidence that carotid endarterectomy (CEA) confers maximum benefit if performed within 14 days from index event. Patients with TIA or minor stroke have an increased risk of early recurrent stroke in the first weeks after the index event, then declining over months. READ MORE

  4. 12. Ultrasonic Methods for Quantitative Carotid Plaque Characterization

    Author : Erik Widman; Matilda Larsson; Mark L. Palmeri; KTH; Karolinska Institutet; Karolinska Institutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Cardiovascular Disease; Carotid Artery; Elasticity; ex vivo; in vivo; Phantom; Plaque; Polyvinyl Alcohol; Pulse Wave Imaging; Shear Wave Elastography; Speckle Tracking; Stroke; Ultrasound; Medical Technology; Medicinsk teknologi; Atherosclerosis;

    Abstract : Cardiovascular diseases are the leading causes of death worldwide and improved diagnostic methods are needed for early intervention and to select the most suitable treatment for patients. Currently, carotid artery plaque vulnerability is typically determined by visually assessing ultrasound B-mode images, which is influenced by user-subjectivity. READ MORE

  6. 14. Ultrasound Image Analysis for Automated Classification of Atherosclerotic Plaque in the Human Carotid Artery

    Author : Peter Holdfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; dynamic programming; carotid artery; Java program; image segmentation; ultrasound images; intima-media thickness; atherosclerotic plaque;

    Abstract : Cardiovascular diseases, caused by atherosclerosis, is one of the most common causes of death in the industrialized world. Two risk factors, that both can be assessed with ultrasound, are the Intima-Media Thickness (IMT) in the arterial wall and the composition of the atherosclerotic plaque. READ MORE

  7. 15. Carotid Artery Wall Layer Dimensions during and after Pre-eclampsia : An investigation using non-invasive high-frequency ultrasound

    Author : Tansim Akhter; Tord Naessen; Anna-Karin Wikström; Henry Nisell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systemic lupus erythematosus; normal pregnancy; pre-eclampsia; high-frequency ultrasound; common carotid artery; intima media ratio; cardiovascular disease.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Pre-eclampsia is associated with increased risk of cardiovascular disease (CVD) later in life. The ‘gold standard’ for estimating cardiovascular risk - ultrasound assessment of the common carotid artery intima-media thickness (CCA-IMT) - does not convincingly demonstrate this increased risk.
