1. 6. No-Touch Saphenous Veins in Coronary Artery Bypass Grafting : Long-term Angiographic, Surgical, and Clinical Aspects

   Författare :Ninos Samano; Domingos Souza; Håkan Geijer; Torbjörn Ivert; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Computed tomography angiography; coronary artery bypass grafting; left internal thoracic artery; no-touch harvesting technique; patency; saphenous vein; Kirurgi; Surgery;

   Sammanfattning : Ischemic heart disease is currently the leading cause of death globally. Coronary artery bypass grafting (CABG) is considered the best treatment for many patients and its success depends on the long-term patency of the conduits. LÄS MER

3. 7. 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

   Författare :Benny Johansson; Eva Swahn; Örebro universitet; []
   Nyckelord :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;

   Sammanfattning : 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. 8. Endothelin and angiotensin II receptors in human coronary arteries and bypass grafts - Alterations in cardiovascular disease

   Författare :Angelica Wackenfors; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; vasoconstriction; receptors; cardiovascular disease; human; coronary arteries;

   Sammanfattning : Angiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis, the contractile Ang II and endothelin receptors were examined in endothelium-denuded human coronary arteries and in bypass grafts (the left internal mammary artery and the saphenous vein), with focus on receptor alterations in cardiovascular disease.

5. 9. 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

7. 10. Endothelial function and dysfunction in coronary artery bypass grafting

   Författare :Ulf Lockowandt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :CABG; Endothelin; Endothelin-blockers; endothelium; lactate; off-pump CABG; prostacyclin; radial artery; unstable angina pectoris;

   Sammanfattning : The integrity of the endothelium is of importance for short- and long-term results following coronary artery bypass grafting (CABG). In this thesis different factors of the endothelial role in the regulation of vascular tone in relation to various current aspects of CABG have been investigated. LÄS MER
