41 Accumulation of CLI Evidences CRITISCH registry BEST CLI BASIL 2 / BASIL trial OLIVE registry SPINACH registry

42 Take Home Message The SPINACH registry explores current clinical outcomes of CLI treatment in real world setting in JAPAN, which provides the data recommending how to select adequate revascularization option in respond to patient s general condition and foot lesion severity. In terms of foot lesion severity, WIfI system are very useful to judge the foot lesion conditions, and especially WIfI W grade and fi grade are very important factors to select revascularization procedure.
