  1. 1. Blood-Graft Interactions: With special reference to cellular immune-reactivity in vascular and endovascular surgery

    Author : Paul Swartbol; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Inflammatory responses; Immunology; Grafts; Vascular; Endovascular; Kirurgi; ortopedi; traumatologi; serology; transplantation; Immunologi; serologi;

    Abstract : The expression of surface adhesion molecules on white blood cells (WBC) and platelets, and the release of tumor necrosis factor-alpha (TNF-a) and interleukin-6 (IL-6) after incubation with expanded-polytetrafluoroethylene (ePTFE)- or woven Dacron grafts was determined. Both graft-materials induced alteration of the WBC adhesion molecule receptor and caused release of TNF-a and IL-6, higher for woven Dacron as compared to ePTFE. READ MORE

  2. 2. On cellular sources for intimal hyperplasia after vascular interventions

    Author : Stefan Mellander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : intimal hyperplasia; vascular intervention; smooth muscle cell; blood-born mononuclear cell; prosthetic graft; balloon injury; pig; rabbit;

    Abstract : Vascular interventions for the treatment of symptomatic atherosclerosis fail in up to 40 % of the cases during the first year. One important reason is the development of a narrowing process known as intimal hyperplasia (IH). The cells forming IH resemble smooth muscle cells (SMCs) from the media of the arterial wall.

  3. 3. Thrombolysis in vascular surgery

    Author : Linn Smith; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Background and aims: Thrombolysis is in common use in the treatment of acute forms of vascular disease. It may be used both systemically and locally, in the latter case through an endovascular approach, socalled catheter-directed thrombolysis. READ MORE

  4. 4. Vascular Wall Responses to Bypass Grafting - Studies in Mice

    Author : Klas Österberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Intimal hyperplasia; graft stenosis; smooth muscle cells; mice; cellular recruitment;

    Abstract : Abstract Vein grafts are frequently used in bypass surgery for treatment of coronary artery disease and lower limb ischemia. Unfortunately the long-term patency is impaired by vein graft stenoses due to intimal hyperplasia (IH). It is assumed that exaggerated intimal thickening is initiated by vessel wall injuries or local flow disturbances. READ MORE

  5. 5. Tissue engineering in blood vessels

    Author : Gisela Helenius; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Abstract : Severely occluded coronary- and peripheral arteries, caused by atherosclerotic plaques, are treated with bypass surgery. Autologous veins are the most commonly used replacement graft. Among the patients that need a vascular bypass, 5-10% lack appropriate replacement veins due to previous surgery of bad quality of the vessels. READ MORE
