  2. 11. Perfusion Monitoring During Oculoplastic Reconstructive Surgery - Opportunities for Optimization of Surgical Techniques

    Author : Khashayar Memarzadeh; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Existing oculoplastic reconstructive surgical techniques are based on empirical knowledge and were established long before perfusion monitoring was possible. It is believed that an avascular graft should always be placed on a vascular bed or flap and also that the viable length of a flap depends on the width of its pedicle. READ MORE

  4. 12. On the use of light for the characterization and treatment of malignant tumours

    Author : Claes af Klinteberg; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diffusion equation; Aminolevulinic acid; Protoporphyrin IX; Photodynamic therapy; Fluorescence spectroscopy; Fluorescence imaging; Laser-Doppler perfusion imaging; Atom- och molekylärfysik; Atomic and molecular physics; Multiple scattering; Tissue optics; Tissue optical properties; Fysicumarkivet A:1999:Klinteberg;

    Abstract : Some aspects on the use of light for tissue characterization and treatment of malignant tumours are discussed within this thesis. The work presented aims at improving optical techniques for tissue characterization, especially to detect malignant and pre-malignant lesions. READ MORE

  5. 13. Laser Speckle Contrast Imaging in Reconstructive Surgery

    Author : Johan Zötterman; Simon Farnebo; Erik Tesselaar; Jacob Wikner; Henry Svensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : ObjectivesReconstructive surgery aims to restore function or normal appearance by reconstructing defective organs after trauma or disease. In patients undergoing reconstructive surgery, previous trauma, surgery or radiotherapy can result in compromised blood supply. READ MORE

  6. 14. Spinal cord oxygenation during thoracic aortic clamping in pigs

    Author : Anders Hellberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Thoracoabdominal aortic replacement; spinal cord ischaemia; cerebrospinal; intrathecal monitoring; oxygen tension; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Despite a dramatic reduction in the mortality associated with thoracoabdominal aorticreplacement during the past 40 years, spinal cord ischaemia that results in paraplegia remainsa serious complication. Simple and reliable intraoperative monitoring techniques are neededto detect impending neurological deficit in time to prevent permanent damage. READ MORE

  7. 15. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

    Author : Qiuxia Zhang; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

    Abstract : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. READ MORE
