a and b: initial runoff prior to revascularization showing high grade stenoses of the proximal segment and a chronic occlusion of the middle and distal segment of the popliteal artery; preserved tibio-peroneal trunc and peroneal artery as well as anterior tibial artery, the latter, however, with a small caliber and impaired distal runoff to the foot; well preserved middle and distal segment of the posterior tibial artery as target vessel for restoring flow to the foot while maintaining perfusion of the peroneal artery; c: failed subintimal recanalization with the 0.014″ CTO wire and 0.018″ support catheter; d: targeted re-entry at the level of the tibio-peroneal trunc to enable further revascularization of the posterior tibial artery; e and f: angioplasty of the popliteal artery and placement of two Supera® stents; g: successful antegrade probing of the proximally occluded posterior tibial artery and subsequent angioplasty; h and i: final result after successful revascularization
