Femur Lengthening in a Patient with a Pseudoaneurysm of the Superficial Femoral Artery Treated with Covered Stent

This case report presents a 29-year-old male patient who presented an articular distal femoral fracture sustained in a road traffic accident in Benin. After the different surgical procedures, the patient presents a knee stiffness and a shortening of the left leg of 7 cm. An ablation of osteosynthesis material and a Judet procedure was done. After this surgical intervention, the patient developed pain, pulsatile swelling of the left knee. A false aneurysm of the superficial femoral artery was evidenced, and a percutaneous endovascular procedure was performed. As a result of the important leg-length discrepancy, a femoral lengthening of 6 cm was performed using intramedullary skeletal kinetic distractor nail. We show that a 6 cm femur lengthening in a patient with a femur stent is possible using intramedullary nails provided that orthopedic and vascular surgeons monitor the patient in strict clinical and paraclinical followup conditions.
