   Sammanfattning : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. LÄS MER

3. 2. Vascular Wall Responses to Bypass Grafting - Studies in Mice

   Författare :Klas Österberg; Göteborgs universitet; []
   Nyckelord :Intimal hyperplasia; graft stenosis; smooth muscle cells; mice; cellular recruitment;

   Sammanfattning : 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. LÄS MER

4. 3. 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.

5. 4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

   Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER

7. 5. Anterior cruciate ligament reconstruction : Anatomic and biomechanical considerations of graft placement and fixation

   Författare :Lars Good; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : This study, comprising 7 separate papers, is concerned with the mechanical causes of graft failure after intraarticular reconstruction of the anterior cruciate ligament (ACL). The study is predominantly experimental in design, but a clinical follow-up is also included to test a causal hypothesis of secondary graft elongation. LÄS MER
