Lower extremity reconstruction with free flaps in patients with only peroneal artery runoff remains a challenge. Here, we present a novel technique for reconstruction of medial defects in the distal leg using a medial approach to the peroneal artery and a short interposition vein graft anastomosed end to side to the peroneal artery. A retrospective, single-center study was performed including all patients who underwent lower extremity reconstruction with free flaps anastomosed to the peroneal artery using a mini vein graft from November 2020 to March 2022. The primary outcome measure was limb salvage. Secondary endpoints were flap survival and postoperative complications. Seven patients received lower extremity free flap reconstruction with a mini vein graft to the peroneal artery. Flap loss rate was 0%. Limb salvage was achieved in five patients (71%). At 6-month follow-up, all patients were ambulatory. One patient died 1 month after surgery due to heart failure. Mini vein graft to the peroneal artery allows reliable and safe free flap reconstruction of distal leg defects in patients with only peroneal artery runoff.

Soft tissue reconstruction in the lower limbs presents a significant challenge, particularly when addressing defects in the distal third of the leg, ankle, and foot. The reverse sural flap reliant on the perforating branches of the peroneal artery has emerged as a versatile option, offering a solution for patients for whom microsurgical techniques are not feasible. Despite its advantages, the procedure carries inherent risks, especially in populations with underlying conditions, such as venous insufficiency, cardiovascular disease, and diabetes, as well as in elderly patients, where the likelihood of flap necrosis is elevated.

Background: Complex lower extremity defects are difficult to cover and often require multiple free tissue transfers. Chimeric anterolateral thigh free flaps (ALTF) and peroneal artery perforator free flaps (PAPF) have been designed specifically as an alternative for reconstruction with arterial end-to-side (ETS) anastomosis. We aimed to assess our institutional experience with this technique and to define its role in complex lower extremity reconstruction.

Background: Intermittent pneumatic compression (IPC) and neuromuscular electrical stimulation can improve deep vein hemodynamics in the lower limbs. We developed a new, small and convenient, and easy to wear common peroneal nerve electrical stimulator (CPNES) and to investigate the effectiveness and safety of CPNES intervention on deep venous hemodynamics.
Methods: Thirty healthy volunteers were recruited and randomly divided into group A and B.

Article Synopsis
- The reconstruction of lower extremity defects with bone or tendon exposure is challenging, and the peroneal artery perforator flap (PAPF) is an effective surgical option for addressing these issues.
- Accurate identification of the peroneal artery's branches and perforators is essential to optimize the flap design and ensure successful transplantation.
- The study highlights the use of preoperative digital subtraction angiography (DSA) and high-frequency ultrasound to visualize and locate anatomically significant branches, aiding in the precision of flap surgery.
