Representative angiograms of Global Limb Anatomic Staging System (GLASS) stage II disease patterns. The target arterial path (TAP) is outlined in yellow. Left panel, TAP includes the anterior tibial (AT) artery. Femoropopliteal (FP) grade is 1 (superficial femoral artery [SFA] occlusion <5 cm). Infrapopliteal (IP) grade is 2 (two focal stenoses of AT artery, total length <10 cm). Right panel, TAP includes the peroneal artery. FP grade is 0 (no significant stenosis). IP grade is 3 (chronic total occlusion of peroneal artery, 3ā10 cm).
