  2. 1. Arterial mechanics : noninvasive identification of constitutive parameters and residual stress

    Author : Jonas Stålhand; Gerhard A. Holzapfel; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis concerns the mechanical modelling of arteries, and particularly a method to identify parameters describing the mechanical properties using only clinically obtainable in vivo measurements. The artery is modelled as a fibre reinforced, incompressible, thick-walled cylinder subjected to large deformations and a residual stress field. READ MORE

  4. 2. Pulse-Synchronous Intramuscular Pressure Oscillations

    Author : Andreas Nilsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compartment syndrome; chronic anterior compartment syndrome; intramuscular pressure; pulse-synchronous oscillations in intramuscular pressure; ; intramuscular arterial pulsations; fiber-optic technique;

    Abstract : Background Intramuscular pressure (IMP) is measured in studies of tissue nutrition and in the diagnosis of compartment syndromes. Patients with compartment syndromes have an elevated IMP due to increased volume in a muscle compartment. READ MORE

  5. 3. Acute, ambulatory and central blood pressure measurements in diabetes

    Author : Magnus Wijkman; Fredrik Nyström; Carl Johan Östgren; Toste Länne; Jan Östergren; Linköpings universitet; []
    Keywords : Ambulatory blood pressure; Arterial stiffness; Central blood pressure; Diabetes; Hypertension.;

    Abstract : Background: In patients with diabetes, high blood pressure is an established risk factor for cardiovascular disease. The aim of this thesis was to explore the associations between blood pressure levels measured with different techniques and during different circumstances, and the degree of cardiovascular organ damage and subsequent prognosis in patients with diabetes.

  6. 4. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus

    Author : Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cerebrospinal fluid; CSF dynamics; Intracranial pressure; Pulse pressure; Normal pressure hydrocephalus; Posture; Predictive tests; Mathematical modelling; Magnetic resonance imaging; Infusion tests;

    Abstract : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). READ MORE

  7. 5. Idiopathic Normal Pressure Hydrocephalus : Cerebrospinal Fluid Tap Test and Magnetic Resonance Imaging as Preoperative Prognostic Investigations

    Author : Johan Virhammar; Elna-Marie Larsson; Katarina Laurell; Kristina Giuliana Cesarini; Magnus Tisell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; normal pressure hydrocephalus; NPH; cerebrospinal fluid disorders; dementia; MRI; CSF tap test; CBF; ASL; Neurology; Neurologi; Neurosurgery; Neurokirurgi; Radiologi; Radiology;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a condition with dilated cerebral ventricles but intracranial pressure within normal limits. The symptoms of gait impairment, cognitive decline and urinary incontinence develop gradually. Treatment with shunt insertion results in improvement in eight out of ten patients. READ MORE
