  2. 11. Noninvasive assessment of cerebral circulation before, during and after carotid surgery

    Author : Helene Zachrisson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal carotid artery disease; cerebrovascular hemodynamics; Carotid thrombendarterectomy; Duplex ultrasound; transcranial Doppler; Internal carotid artery disease;

    Abstract : Non-invasive ultrasound investigations were evaluated in patients with carotid artery stenosis in comparison with radiological disease gradations and perioperative blood pressure measurements. The aim was to assess cerebrovascular hemodynamics before, during and after carotid thrombendarterectomy (CEA) in relation to the clinical outcome of the surgical intervention. READ MORE

  4. 12. Carotid artery disease : plaque features and vulnerability

    Author : Fisnik Jashari; Michael Henein; Per Wester; Christine Kremer; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carotid atherosclerosis; ultrasound; plaque features; echogenicity; calcification; surface plaque irregularities; subclinical atherosclerosis; cerebrovascular symptoms; Cardiology; kardiologi; cardiovascular disease; hjärt- och kärlforskning;

    Abstract : Background: Atherosclerosis is an important cause of stroke. Ultrasound offers the convenience of real-time and detailed assessment of carotid plaque features as well as arterial wall thickening and composition. READ MORE

  5. 13. Vascular dementia - classification and clinical correlates

    Author : Ulla Andin; Lund Psykiatri; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psychosomatics; Psychiatry; clinical psychology; Medicine human and vertebrates ; falls; clinical course; hypertension; orthostatic hypotension; dizziness; cerebrovascular disease; Alzheimer?s disease; Neuropathological subgroups; cardiovascular disease; Psykiatri; klinisk psykologi; psykosomatik; Medicin människa och djur ;

    Abstract : During the period (1976-1995) a total of 175 consecutive patients (m 88/f 87) with neuropathologically verified vascular dementia (VaD) were examined. 22 patients with pure Alzheimer's Disease (AD) were also studied. All patients were diagnosed and followed at the Department of Psychogeriatrics (Lund University Hospital). READ MORE

  6. 14. Strategies for assessing health risks from two occupational cohorts within the domain of northern Sweden

    Author : Ove Björ; Tohr Nilsson; Håkan Jonsson; Lena Damber; Per Gustavsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cohort; mortality; incidence; risk; rate; cancer; cerebrovascular diseases; exposure; occupational; mining; industry; worker; Poisson regression; Cox regression; SMR; causal inference; G-estimation; Occupational and Environmental Medicine; arbets- och miljömedicin; epidemiologi; Epidemiology;

    Abstract : Background: Studies based on a cohort design requires access to both subject-specific and period-specific information. In order to conduct an occupational cohort study, access to exposure information and the possibility and permission to link information on outcomes from other registers are generally necessary.

  7. 15. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

    Author : Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

    Abstract : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. READ MORE
