Ruptured saphenous vein graft (SVG) aneurysm is a rare source of significant morbidity and mortality. SVG is a common technique of coronary artery bypass grafting (CABG), but vein graft aneurysm and ruptured SVG aneurysm have not received the required attention as only few case reports exist. We present the case of a 50-year old man with ruptured vein graft aneurysm who had significant postoper...

INTRODUCTION It has been suggested that endothelial dysfunction is critical to saphenous vein graft (SVG) occlusion. AIM To evaluate in vivo endothelium-mediated vasoreactivity in angiographically non-stenotic SVG. METHODS The group consisted of 31 patients (pts), aged 58.7+/-8.7 years, 54+/-38 months after coronary bypass surgery. In each patient one angiographically normal SVG was selecte...

OBJECTIVE To measure the serum erythropoietin (EPO) level in patients with saphenous vein grafts (SVGs) and to compare the EPO level in those with and without SVG disease. SUBJECTS AND METHODS The study included 85 consecutive patients with a history of coronary artery bypass graft surgery that underwent elective coronary angiography. Patients with >30% stenosis (diseased grafts) in at least ...

There is higher long-term failure of the saphenous vein graft (SVG) compared with the left internal mammary artery (LIMA) graft, which is affected by the hemodynamic environment. A comprehensive analysis of postoperative structure-function changes is important to study the atherogenesis in the SVG A comparison of morphometric and hemodynamic parameters was carried out between LIMA grafts and SV...

Background Patients with degenerated saphenous vein grafts (SVG) have a higher risk of developing no-reflow. The CHA2DS2-VASc score was established as no-reflow predictor in patients acute coronary syndrome (ACS). Objectives In our study, we aimed to assess the association between and after procedure short-term mortality SVG who underwent elective percutaneous intervention (PCI). Methods Our re...

OBJECTIVES To define long-term efficacy of different stent types in saphenous vein graft (SVG) interventions. METHODS In BASKET (Basel Stent Cost Effectiveness Trial), major adverse cardiac events (MACE), i.e. cardiac death, myocardial infarction and symptom-driven target vessel revascularization (TVR) were assessed after 18 months comparing drug-eluting stents (DES) versus bare metal stents ...

BACKGROUND Endovenous laser ablation (EVLA) is a treatment option for lower extremity varicose veins. In the present study, we investigate to the genetic changes and possibility of living tissue in the saphenous vein wall after the EVLA procedure. METHODS Eleven saphenous vein grafts were randomized in two groups: (1) 4 cm SVG segments of performed EVLA procedure in study group, (2) 4 cm segm...

The advancement of aircraft engines relies heavily on film cooling technology. To enhance the efficiency in high-pressure turbines, many passive flow control methods have been explored. Downstream hole, a semi-sphere vortex generator (SVG) decreases lateral dispersion coolant and increases cooling. better understand influence uncertainty SVG parameters such as compound angle, size, location, su...

This meta-analysis was undertaken to assess the efficacy and safety of drug-eluting stents (DESs) compared to bare metal stents (BMSs) in saphenous vein graft (SVG) interventions. DESs decrease the risk of target vessel revascularization in native coronary arteries compared to BMSs. The ideal treatment strategy in patients with SVG disease is unknown. A search of the published reports was condu...

BACKGROUND Although saphenous vein grafts (SVG) have been used from 1975 to treat coronary stenosis caused by Kawasaki disease, long-term results after more than 20 years remain unknown. METHODS AND RESULTS From 1981 to 1997, 13 patients underwent coronary artery bypass grafting using SVG (n=20). The age at operation ranged from 2 to 20 years (median 11 years), the age at latest angiography f...
