The Global Vascular Guideline on chronic limb threatening ischemia (CLTI) proposes the Global Limb Anatomic Staging System (GLASS), a new angiographic scoring system to quantify the anatomic severity of infrainguinal disease in CLTI patients. However, GLASS validation still needs to be completed, and the infrapopliteal (IP) target artery pathway (TAP) was easily influenced by the procedures. Thus the IP target artery could be selected either as the least diseased artery based on angiography or prospectively based on the angiosome concept. So the investigators aim to evaluate its correlation with clinical outcomes after revascularization.
