ABSTRACT
The chapter discusses case presentations to review some of the scenarios that may be encountered during interventional procedures. Interventional radiology is playing an increasingly important role in patient care. Its efficacy is widely accepted, and there is a low incidence of complications with most procedures. None the less, complications clearly do occur, and it is imperative that all medical personnel who deal with interventional radiology are aware of what can go wrong, how to prevent complications, and how to treat them should they arise. Vasovagal reactions can occur with any intervention. They clearly occur after the injection of contrast agents, but they also arise in response to needle sticks or even to anxiety alone. They are often heralded clinically by nausea, diaphoresis and light-headedness. In any situation in which the patient is experiencing a reaction, vital signs should be obtained.
