Infections associated with arterial reconstructions of the lower limbs are associated with high morbidity. This article reviews the risk factors for infection associated with this surgery and the preventive measures. These include smoking cessation and glycemic control preoperatively; avoiding unnecessary exposure to antibiotics or corticosteroids; optimal peripheral wound care; rigorous antisepsis and antibiotic prophylaxis in the operating theatre ; and finally, meticulous post-operative wound monitoring. The benefit of Staphylococcus aureus decolonization in vascular surgery is less clearly established than in cardiac and thoracic surgery, but it is still recommended in cases of implant placement or where there is a high risk of S. aureus infection, depending on the planned approach and type of surgery.
