  1. 1. Harvesting of Saphenous Vein for Coronary Artery Bypass Grafting : An Improved Technique that Maintains Vein Wall Integrity and Provides a High Early Patency Rate

    Author : Domingos Souza; Kjell Rådegran; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Saphenous vein; coronary bypass; endothelium; nitric oxide; patency rate; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Abstract : The primary aim of this thesis was to modify saphenous vein (SV) harvesting technique and evaluate its clinical importance. A new "no touch" (NT) technique of SV preparation was developed where the vein is harvested with a pedicle of surrounding tissue, which protects the vein from spasm therefore obviating the need for distension.

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

    Author : Mats Dreifaldt; Domingos Souza; Lars Norgren; Mats G. Karlsson; Michael R. Dashwood; Anders Jeppson; Örebro universitet; []

    Abstract : 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. READ MORE

  3. 3. No touch vein harvesting technique for coronary artery by-pass surgery : impact on patency rate, development of atheroscleosis, left ventricular function and clinical outcome during 16 years follow-up

    Author : Benny Johansson; Eva Swahn; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; coronary artery disease; coronary artery bypass grafting; vein grafts; no touch vein harvesting technique; intravascular ultrasound; echocardiography; clinical outcome; revascularization; outcome analysis; angina pectoris; myocardial infarction; mortality; randomized trial; Surgery; Kirurgi;

    Abstract : This thesis was based on a prospective randomized trial which was started in 1993 to compare the no touch (NT) with the conventional (C) technique of saphenous vein harvesting for CABG.In paper I, was demonstrated superior patency for the NT grafts at short-term (1.5 years; 95,6% vs 89%; p < 0,05) and long-term follow-up (8.

  4. 4. Hepatic and Portal Vein Thrombosis : studies on epidemiology and risk factors

    Author : Rupesh Rajani; Sven Almer; Tomas Lindahl; Dominique-Charles Valla; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Budd-Chiari syndrome (BCS) i.e. thrombosis in the hepatic veins and/or inferior vena cava, and portal vein thrombosis (PVT) are rare disorders. Epidemiological data are scarce and previous reports have been from highly specialised referral centres. READ MORE

  5. 5. Hyaluronan and the receptor CD 44 in the heart and vessels : a study in normal and pathological conditions

    Author : Martin Hellström; Anna Engström-Laurent; Bengt Johansson; Lena Jonasson; Umeå universitet; []
    Keywords : hyaluronan; CD44; heart; Rat; cardiac hypertrophy; artery; vein; human; Medicine; medicin;

    Abstract : Tissues are not solely composed of cells. The extracellular matrix is important for the cell well-being and cell-cell communication. The glycosaminoglycan hyaluronan (HYA) is a widely distributed extracellular matrix (ECM) component. READ MORE
