  1. 1. Thrombolysis in vascular surgery

    Författare :Linn Smith; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 2. Tissue engineering in blood vessels

    Författare :Gisela Helenius; Göteborgs universitet; []
    Nyckelord :tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Sammanfattning : 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. LÄS MER

  4. 3. Engineering the shape of bacterial cellulose and its use as blood vessel replacement

    Författare :Henrik Bäckdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering.; smooth muscle cells; bacterial cellulose; scaffold design; tubular fermentation; biocompatibility evaluation; Blood vessel; vascular graft;

    Sammanfattning : Tissue loss and organ failure are major health problems that impose great costs on society. Cardiovascular diseases are responsible for 36% of mortalities and the disease burden among adults over the age of 60. The single largest cardiovascular disease is atherosclerosis in the coronary artery. LÄS MER

  5. 4. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    Författare :Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. LÄS MER

  7. 5. Extracellular matrix-mediated signaling in the regulation of vascular smooth muscle cell phenotype and function

    Författare :Joy Roy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease is the leading cause of mortality in the world. Even though death rates are today dropping in the developed countries, disability due to the disease is rising worldwide. The major portion of cardiovascular disease associated deaths is due to occlusive atherosclerotic lesions. LÄS MER
