A 89‐year‐old male presented with severe untreatable pain and ischemic non‐healing ulcer in the left forefoot. The pre‐procedural angiograms showed multiple stenosis of the superficial femoral and popliteal arteries, occlusion of anterior tibial artery, tibio‐peroneal trunk (TTP) and distal posterior tibial artery (PTA), stenosis of the peroneal artery, and the patency of the medial plantar artery (MPA) as a single pedal artery, with very poor perfusion of the lateral aspect of the forefoot. The TTP and PTA were recanalized, and balloon angioplasty of superficial femoral artery and popliteal artery and peroneal artery was carried out. After unsuccessful antegrade attempts, the lateral plantar artery (LPA) was retrogradely recanalized performing the medial‐to‐lateral plantar loop, navigating from the deep branch of MPA to the plantar arch and reentering back in the common plantar artery through the LPA. Balloon angioplasty of LPA was performed though the retrograde and antegrade route. When the MPA is the single pedal artery, and the antegrade recanalization of the dorsalis pedis artery (DPA) and the LPA is not possible, the medial‐to‐lateral plantar loop is a feasible technique to recanalize the LPA retrogradely through the plantar arch.

Purpose: To report a new technique to reenter the common femoral artery (CFA) true lumen after retrograde recanalization of a superficial femoral artery (SFA) with flush ostial occlusion. Technique: The technique is demonstrated in a 76-year-old woman with critical limb ischemia previously submitted to several surgical revascularizations. A duplex ultrasound showed flush ostial occlusion of the SFA and patency of the anterior tibial artery at the ankle as the sole outflow vessel. After unsuccessful antegrade attempts to recanalize the SFA, a retrograde guidewire was advanced subintimally up to the CFA, without gaining reentry. A balloon catheter was inflated in the subintimal plane across the SFA ostial occlusion. Antegrade access to the distal CFA was achieved with a 20-G needle, which was used to puncture the balloon. A guidewire was advanced into the balloon and pushed forward while the collapsed balloon was pulled back to the mid SFA. The antegrade guidewire was externalized through a retrograde catheter, which was pushed in the CFA true lumen. A retrograde guidewire was advanced and externalized through the femoral sheath, establishing a flossing wire. The procedure was completed in antegrade fashion. Conclusion: The FORLEE technique is a cost-effective option to gain the CFA true lumen after subintimal retrograde recanalization of an ostial SFA occlusion.

Background: Charcot neuroarthropathy of the foot/ankle is a devastating complication of diabetes. Along with neuroarthropathy, osteomyelitis can occur which can result in amputation. This prospective study evaluated a limb salvage procedure as an alternative to amputation through surgical treatment of osteomyelitis of the midfoot or the ankle and stabilization with external fixation. Materials and Methods: Forty-five patients with Charcot arthropathy and osteomyelitis underwent debridement and attempted fusion with an external fixator. Chart and radiograph review was performed to assess the success of the fusion and eradication of infection. Results: Out of 45 patients, 39 patients healed using emergent surgery to drain an acute manifestation of the infection while maintaining the fixation for an average of 25.7 weeks. Two patients were treated with intramedullary nail in a subsequent surgical procedure. In four patients, the infection could not be controlled, therefore a major amputation was carried out. Conclusion: For select patients, external fixation proved to be a reasonable alternative to below-knee amputation. Level of Evidence: IV, Case Series

Purpose: To evaluate arterial patency and factors influencing outcomes after successful tibial artery angioplasty in patients with critical limb ischemia (CLI)....
