Vascular surgery includes various surgical procedures and sites. Infec
tious risk is low but with a high functional risk and a high mortality
rate. Infection rik factors are numerous. Among them the incision in
the Scarpa's triangle is at the first place. Antimicrobial prophylaxis
in vascular surgery has shown its efficacy whatever the agent. The se
cond generation cephalosporins are the most logical, with a duration o
f administration of less than 24 hours. In case of re-operation glycop
eptides have shown their efficacy.
