    Sammanfattning : Treatment for varicose veins (VV) is insufficiently evidence based and recurrence rates are high. The aim of this thesis was to study the long-term results after VV surgery, risk factors for recurrences and the effect of preoperative duplex scanning on recurrence rate, quality of life (QoL) and costs.

  5. 4. Conduits in coronary artery bypass grafting surgery : Saphenous vein, radial and internal thoracic arteries

    Författare :Mats Dreifaldt; Domingos Souza; Lars Norgren; Mats G. Karlsson; Michael R. Dashwood; Anders Jeppson; Örebro universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac surgery; Coronary artery bypass; Saphenous vein; Radial artery; Internal thoracic artery; Vasa vasorum; Nitric oxide; Graft patency; Medicine; Medicin;

    Sammanfattning : A novel technique for saphenous vein (SV) graft harvesting, the No-touch technique (NT), has been developed at the Dept. of Cardiovascular surgery, Örebro University hospital. With NT the SV is harvested with a pedicle of surrounding tissue. This avoids graft spasm and eliminates the need for distension. LÄS MER

  7. 5. Wide-angle scanning wide-band phased array antennas

    Författare :Anders Ellgardt; Martin Norgren; Lars Josefsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis considers problems related to the design and the analysis of wide-angle scanning phased arrays. The goals of the thesis are the design and analysis of antenna elements suitable for wide-angle scanning array antennas, and the study of scan blindness effects and edge effects for this type of antennas.
