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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Ultrasound evaluation of atherosclerosis and other cardiovascular sources of cerebral embolism

    Författare :Robert Wetterholm; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :stroke; atherosclerosis; aorta; echocardiography; ultrasound; IMT; MES; WHHL;

    Sammanfattning : The search for embolic sources has high priority in patients presenting with suspected cerebral embolism. Non-invasive cardiovascular ultrasound is frequently used to reveal the presence of carotid stenosis and cardiac disorders with embolic potential. LÄS MER

    Sammanfattning : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. LÄS MER
