Introduction: 12,000 infrainguinal bypass grafts are performed annually in the UK. Despite improvements in surgical technique, outcomes remain suboptimal: 20% of above knee grafts require intervention to maintain patency by 3 years. Only antiplatelet agents have been demonstrated thus far to improve graft survival. 80% of graft failure is as a result of intimal hyperplasia, an inflammatory process characterised by the proliferation and migration of vascular smooth muscle cells. Toll Like Receptors (TLR), part of the innate immune system, have been implicated in atherosclerosis formation but no

The most common cause of vein bypass graft failure in the postoperative period of 1 month to 1 year is stenosis, which occurs in up to 30% of arterial reconstructions. This thesis investigates the intimal hyperplasia underlying such lesions using a laboratory model. The first chapter reviews the current literature regarding vein graft stenoses and is followed in Chapter 2 by a brief introduction to tissue and organ culture and their usefulness as investigative research tools. Before embarking on a study of a pathological condition, Chapter 3 studies the structure of the "normal" long saphenous

Cardiovascular diseases (CVD) remain the most common cause of death in the United States. Additionally, peripheral artery disease affects thousands of people each year. A major underlying cause of these diseases is the occlusion of the coronary or peripheral arteries due to arteriosclerosis. To overcome this, a number of vascular interventions have been developed including angioplasty, stenting, endarterectomies and bypass grafts. Although all of these methods are capable of restoring blood flow to the distal organ after occlusion, they are all plagued by unacceptably high restenosis rates. Wh

Restenosis due to intimal hyperplasia is a major clinical problem that compromises the success of angioplasty and endovascular surgery. The pathogenesis of restenosis is multifactorial, involving such events as endothelial injury, inflammation, platelet activation, and hyperplasia of the intima, primarily due to vascular smooth muscle cell replication (vSMC). The incidence of intimal hyperplasia varies in different risk populations, e.g., diabetic patients, up to 35% of whom require bare metal stent implantation; clinical evidence has shown that this value is reduced but continues to cause pro

H2S is a biologically relevant signaling gas that is endogenously produced throughout the body.

However, many small molecule H2S donors suffer from poor solubility, low stability, and lack of control over H2S release rates. As a result, there has been an increasing interest in utilizing supramolecular materials for exogenous H2S delivery.

Une complication fréquente de cette intervention est la resténose intra-stent qui mène à une nouvelle obstruction de la lumière artérielle. Cette pathologie repose sur le processus d'hyperplasie intimale, combinaison d'une inflammation locale et d'une modulation phénotypique des cellules musculaires lisses (CML) de la paroi artérielle. Afin de pallier à cette pathologie, les stents ont été recouverts d'agents anti-prolifératifs. Bien qu'efficace dans la prévention de la resténose, l'utili

Streszczenie:
Saphenous vein graft disease represents an unresolved problem in coronary artery bypass grafting. After surgery, progressive modification in the vein wall occurs, leading to occlusion of the graft lumen. This process, called intima hyperplasia, involves the participation of vein-resident cells as well as the recruitment of vein-extrinsic cells. Arterial wall strain has recently emerged as one of the factor that can contribute to the pathogenesis of the vein graft disease. Therefore, in collaboration with Department of Bioengineering, Politecnico di Milano we developed a culture system for the

Peripheral vascular grafts are used for the treatment of peripheral arterial disease and arteriovenous grafts for vascular access in end stage renal disease. The development of neo-intimal hyperplasia and thrombosis in the distal anastomosis remains the main reason for occlusion in that region. The local haemodynamics produced by a graft in the host vessel is believed to significantly affect endothelial function. Single spiral flow is a normal feature in medium and large sized vessels and it is induced by the anatomical structure and physiological function of the cardiovascular system. Grafts

The main methods to treat coronary artery disease are percutaneous transluminal coronary angioplasty, with or without stent implantation. But within the following 6 months after the operation, nearly 30 - 50％ of the patients have coronary restenosis. Previously, reports showed that cannabinoid system might play a role in the treatment of atherosclerosis. Delta-9-tetrahydrocannabinol, or 6a, 7, 8, 10a-tetrahydro-6,6,9-trimethyl-3-pent

(ENGLISH) Background: The investigation of the immunosuppression usage in cardiovascular surgery and interventional cardiology is, at present, concentrated on three main topics: 1) influence on intimal hyperplasia of coronary and peripheral vascular reconstructions 2) influence on rejection of allogeneic vascular grafts and 3) influence on intimal hyperplasia of coronary arteries after endovascular interventions. Modern immunosuppressive drug FK506 (Tacrolimus) could have a positive effect for these indications. In experimental study, FK506 inhibited rejection of arterial allografts and also i
