摘要：Patients presenting with recurrence of anginal symptoms after saphenous vein bypass surgery pose an increasingly frequent challenge.In general, approximately 40％ to 50％ of saphenous vein graft (SVG) will become diseased or occluded within the first ten years after surgery[1] Because adverse clinical outcomes, such as high restenosis rates and distal embolization, have been reported, percutaneous coronary intervention (PCI) for SVG is not recommended as a first-line strategy.[2] Distal embolization occurs in 2％-17％ of patients despite advances in therapy, including the utilization of embolic protection device (EPD), which may lead to increased mortality at both short follow-up and midterm follow-up,[3] However, these patients often associated with inappropriate anatomic characteristics of native vessel intervention including calcification, tortuosity, abundant plaque burden, and complex chronic total occlusion (CTO) lesions.Moreover, repeat coronary bypass surgery is an option but is technically more demanding and is associated with a higher mortality.Therefore, it can sometimes result in SVG stenosis being the only intervention option.This is why the recanalization of SVG lesions, especially totally occluded lesions, remains one of the most challenging procedures in interventional cardiology.
