  1. 6. Resuscitative endovascular balloon occlusion of the aorta : Physiology and clinical aspects of an emerging technique

    Författare :Mitra Sadeghi; Tal M. Hörer; Kristofer F. Nilsson; Per Skoog; Kjell Jansson; Kevin Mani; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; REBOA; trauma; hemorrhage; partial REBOA; Ischemia reperfusion injury; blood pressure titration; endtidal cabondioxide; traumatic inflammatory response;

    Sammanfattning : Traumatic hemorrhagic shock is a major cause of death worldwide. Patients enter the fatal triad of hypothermia, acidosis and coagulopathy and die quickly due to cardiovascular collapse. Ideally, procedures should be performed at the injury scene to prevent this fatal event. LÄS MER

  3. 7. Inhibition of smooth muscle cell proliferation after balloon injury

    Författare :Bojan Cercek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Smooth muscle cell proliferation is an important part of the arterial response to injury Insulin like growth factor-I (IGF-I) is involved in regulation of cell proliferation and hypopituitarism is associated with decreased vessel wall response to injury. We investigated the role of vascular IGF-I in vessel wall response to injury. LÄS MER

  4. 8. On cellular sources for intimal hyperplasia after vascular interventions

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

    Sammanfattning : 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.

  5. 9. The role of the adventitia and perivascular tissue for the formation of intimal hyperplasia

    Författare :Per Fogelstrand; Göteborgs universitet; []
    Nyckelord :Intimal hyperplasia; adventitia; perivascular tissue; smooth muscle cells; fibroblasts; balloon injury; vein graft; artificial graft;

    Sammanfattning : Symptomatic atherosclerosis is commonly treated with balloon angioplasty or bypass surgery. About 30% of the interventions will re-narrow within a year due to restenosis and graft-stenosis. Thickening of the luminal layer, the intima, is an important component in these side-effects.

  7. 10. Resuscitative Endovascular Balloon Occlusion of the Inferior Vena Cava (REBOVC) : Experimental and clinical studies

    Författare :Maria B. Wikström; Kristofer F. Nilsson; Tal M. Hörer; Pirkka Vikatmaa; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retrohepatic inferior vena cava; trauma; injury; hemorrhagic shock; endovascular; REBOVC;

    Sammanfattning : Juxtahepatic venous injuries often cause life-threatening hemorrhagic shock, the mortality is high and new management methods are needed. The aims were to explore endovascular methods for retrohepatic vascu-lar isolation, their effects on survival, hemodynamics, metabolism, end-organ damage and bleeding, and if ultrasound and anatomical land-marks could be used to guide placement of resuscitative endovascular balloon occlusion of the inferior vena cava (REBOVC).
