The type of pathology and the current therapeutic tendencies justify that endovenous therapy is the most frequently selected one. Although it has multiple advantages, it bears with it a series of infectious type complications (bacterial infections, phlebitis and thrombophlebitis). Even though bacterial infections in peripheral intravascular vessels have a low occurrence rate, which some authors list as between 1 and 2%, in central intravascular vessels, their occurrence is usually higher. Phlebitis is one of the complications most frequently associated with the use of peripheral intravascular catheters.
