Representative angiograms of Global Limb Anatomic Staging System (GLASS) stage III disease patterns. The target arterial path (TAP) is outlined in yellow. Left panel, TAP includes the peroneal artery. Femoropopliteal (FP) grade is 4 (superficial femoral artery [SFA] disease length, 10–20 cm; popliteal stenosis <5 cm; heavily calcified). Infrapopliteal (IP) grade is 2 (stenosis of tibioperoneal trunk and proximal peroneal <10 cm). Right panel, TAP includes the anterior tibial (AT) artery. FP grade is 4 (popliteal chronic total occlusion extending into trifurcation). IP grade is 3 (chronic total occlusion of target artery origin).
