OVERVIEW
It is very critical to avoid moving the wire when advancing equipment over the wire. It is dangerous for the wire to move forward without knowledge of the interventional radiologist. Similarity if the wire moves back access into a specific anatomical space may be lost unnecessarily. It is for this reason that a pinch/push technique is implemented which involves pinching the wire and pushing the device that is being advanced to ensure that the wire does not move. The video below helps demonstrate this technique.
