  1. 1. 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

  2. 2. Imaging Studies of Olfaction in Health and Parkinsonism

    Author : Charalampos Georgiopoulos; Elna-Marie Larsson; Maria Engström; Nil Dizdar; Helene Zachrisson; Asta Kristine Håberg; Linköpings universitet; []

    Abstract : Olfactory loss is a common non-motor symptom of Parkinson’s disease (PD), often preceding the cardinal motor symptoms of the disease. The aim of this thesis was to: (a) evaluate whether olfactory examination can increase diagnostic accuracy, and (b) study the structural and functional neural basis of olfactory dysfunction in PD with different applications of Magnetic Resonance Imaging (MRI).

  3. 3. Lower limb venous incompetence and the effect of radiofrequency ablation versus open surgery : Focus on haemodynamics, quality of life and health economic aspects

    Author : Oskar Nelzén; Helene Zachrisson; Toste Länne; Johan Skoog; Gunnar Plate; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic venous incompetence; Varicose veins; Radiofrequency ablation; High ligation stripping Duplex ultrasound; Strain-gauge plethysmography; Quality of Life; Health economic evaluation;

    Abstract : Chronic venous incompetence (CVI) is a common condition, and varicose vein treatment is one of the most-common surgical procedures performed worldwide. Common symptoms of CVI are pain, cramps, itching, feeling of leg heaviness and venous claudication. Advanced CVI can lead to skin changes, eczema and venous ulcers. READ MORE

  4. 4. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

    Author : Johan Skoog; Toste Länne; Marcus Lindenberger; Helene Zachrisson; Ola Eiken; Linköpings universitet; []

    Abstract : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. READ MORE

  5. 5. Ultrasound Assessment and Vascular Mechanics in Takayasu Arteritis and Systemic Lupus Erythematosus

    Author : Christina Svensson; Helene Zachrisson; Christopher Sjöwall; Per Eriksson; Andreas P. Diamantopoulos; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Takayasu arteritis (TAK) and systemic lupus erythematosus (SLE) are inflammatory diseases that primarily affect young women. TAK is a rare vasculitis that affects the aorta and its main branches, whereas SLE is a chronic autoimmune disease that effects multiple organs. READ MORE
