Popliteal entrapment syndrome (PES) can be a rare cause of chronic or acute lower limb ischemia. PES is characterized as an abnormal relationship between the neurovascular and tendomuscular structures within the popliteal fossa. This mallocation may lead to progressive injury of the popliteal artery. In the case of a 7-year-old boy, PES led to a popliteal artery aneurysm (PAA) with a concomitant acute embolization into the peripheral arteries of the lower limb. Embolectomy and resection of the PAA with interposition of a saphenous graft did not establish a durable therapy. Six months after the operation, we observed a recurrence of the PAA (within the saphenous interposition graft). Only the lateralization (here, of the graft) into an orthotopic location led to long-term success. PES is a progressive disease in which surgical transposition of the popliteal artery with or without saphenous interposition is the treatment of choice.
