Introduction
This advice sheet has been produced to give you information about extravasation of radio-graphic contract material.
Radiotherapy Department
As part of your Radiotherapy planning (CT) scan we were required to use an injection of contrast media (dye) into one of your veins. Sometimes, during this procedure an extravasation (leak) may occur. This occurs when the contrast material (dye) used to optimise your treatment planning scan, leaks out of the vein into the surrounding tissue. When this happened, you may have felt some pain or tightening around the injection site.
This advice sheet aims to explain what you may see / feel and what you should do following an extravasation incident. It is not meant to replace discussion between you and the healthcare team. If after reading it you require further explanation please discuss this with the relevant person who has been caring for you.
You will have been observed for approximately two hours after the extravasation incident occurred and a pressure bandage may have been applied. Before you leave the department a doctor will explain what has happened and what further signs to look out for.
