1. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta
Abstract : 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. READ MORE

2. Vascular Wall Responses to Bypass Grafting - Studies in Mice
Abstract : 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. READ MORE

3. The role of the adventitia and perivascular tissue for the formation of intimal hyperplasia
Abstract : 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.

4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis
Abstract : 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. READ MORE

5. Anterior cruciate ligament reconstruction : Anatomic and biomechanical considerations of graft placement and fixation
Abstract : 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. READ MORE
