OBJECTIVES We evaluated the early and mid-term (18-month) clinical events in a consecutive series of patients undergoing a nonstaged multiple saphenous vein grafting (SVG) intervention with stents as compared with a single SVG stent procedure. BACKGROUND Saphenous vein graft angioplasty has been limited by high rates of distal embolization, myocardial infarction, restenosis and late mortality...

Percutaneous intervention carries a higher risk of distal embolization and poorer outcome in saphenous vein grafts (SVG) than in native coronary vessels. Embolic protection devices (EPD) have demonstrated value in decreasing the risk of embolization and post-procedural enzymes elevation after SVG intervention. Although there is ample evidence to support the routine use of EPD for SVG interventi...

A new XML technology, called Scalable Vector Graphics (SVG) will bring the fast and highresolution vector graphics that we currently enjoy in the print world to the Web. SVG overcomes the shortcomings of existing pixel-based web graphics and contains more sophisticated features, such as scripting, gradients, animation, filter effects, and interactivity. It’ll integrate seamlessly with tradition...

This paper tries to make some spatial extensions to W3C’s Scalable Vector Graphics (SVG) Specification to support SVG-based spatial information representation and analysis in the Web environment. Based on the theory of spatial data modeling, this paper attempts to find a theoretical foundation for SVG-based spatial information representation. And then, based on this theoretical foundation, we p...

OBJECTIVES We sought to examine saphenous vein graft (SVG) lesions that fail within the first year after operation. BACKGROUND Saphenous vein grafts remain patent for approximately 10 years; however, up to 15% to 20% of SVGs become occluded within the first year. METHODS We studied 100 patients who underwent percutaneous coronary intervention (PCI) for early (<1 year post-implantation) SVG ...

Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVG) with metallic stents is associated with a high rate of restenosis (19–21%) and target vessel failure in the long-term follow-up [1]. Potentially, implantation of a bioresorbable vascular scaffold (BVS) (ABSORB, Abbott Laboratories) into the stenotic SVG may be an alternative to metallic stents [2]. Although the effectivenes...

Percutaneous coronary intervention (PCI) of saphenous vein graft (SVG) is associated with higher adverse event rates, lower procedural success, and inferior longterm patency rates compared with native vessel PCI. The ability to comply with dual antiplatelet therapy, and whether the patient will need an interruption in dual antiplatelet therapy, should be considered when deciding whether to impl...

A man showed a 90% narrowing at the origin of a saphenous vein graft (SVG) 6 years after bypass surgery. After 4 days of intravenous thrombolytic therapy the narrowing in the SVG disappeared completely. Thus, late stenosis of SVG can be caused by thrombosis not superimposed on organic narrowing.

SVG (Scalable Vector Graphics) is expected to be a new standard for graphic data on the Internet. In the near future, many maps on the Internet will be formatted as SVG. SVG-formatted maps are relatively easy to be understood by machines because of their internal design structures compared with image-formatted maps which have been mainly used as graphics on the Web. This paper introduces backgr...

OBJECTIVES The aim of this study was to examine the incidence of clinical events after implantation of the TAXUS Express (Boston Scientific Corporation, Natick, Massachusetts) paclitaxel-eluting stent in saphenous vein graft (SVG) lesions in an unselected patient population. BACKGROUND Saphenous vein grafts have 1-year occlusion rates of 12% to 20%, with >50% failure by 7 to 10 years. Many di...
