Vein graft (SVG) stenting
Vein grafts are used during bypass surgery to bypass the blood flow through narrowed coronary arteries. These are mostly taken from leg and used in the heart. Over a period of time, the vein grafts itself can get narrowed and cause chest pain. An angiogram of the graft will confirm this and this may require intervention in the form of angioplasty. Vein graft angioplasty is challenging, as the walls of veins are different from arteries. There is also high risk of clots going down the graft during ballooning process. This requires expertise and also special devices to prevent this happening and to get good result from angioplasty.
