Methicillin-Resistant Staphylococcus aureus Infection to a Stent Graft in the Superficial Femoral Artery

Endovascular therapies for peripheral artery disease have become widespread, but the risk of device infection, though rare, must be considered. Prompt management is essential to preserve the patient's limb and life. A 79-year-old man presented with intermittent claudication and resting pain in his left leg and underwent multiple endovascular treatments targeting the lesion in the left superficial femoral artery. After treatment, he developed fever, swelling, and pain in his right thigh. Further evaluation revealed an infection of a previously implanted stent graft in the right superficial femoral artery, necessitating surgical removal of the graft. Stent graft infections, though uncommon, can have severe consequences. Prevention and early detection are critical, but diverse patient and lesion backgrounds often complicate this process. This case highlights the potential risks of infections in implanted devices for peripheral artery disease and underscores the importance of proper management.
