Information for patients
This leaflet can be made available in other formats including large print, CD and Braille and in languages other than English, upon request.
You have had a CT scan, with a contrast injection. This leaflet describes how to manage the extravasation of contrast.
What is extravasation?
Contrast (X-ray dye) is given to you through a cannula (fine tube) in a vein, usually in your arm or hand. Extravasation is when the dye leaks out under your skin instead of going into your vein. This is rare.
What will happen next?
If this happens, it may sting around the area and it can be painful. The Radiographer will remove the cannula and will massage your arm.
A cold compress (a small ice pack that helps to ease pain) will be put on to the area and your arm will be elevated. The area may be swollen and painful for around 30 minutes.
If the scan was not completed, the Radiographer will talk to you about placing another cannula to complete the test. This can be postponed until another day if you prefer.
Can I do anything at home?
Yes, you can do the following:
- Massage the area.
- If there is swelling, keep the arm elevated as much as possible. This will help reduce the swelling.
- You can use an ice pack or bag of frozen vegetables. This can be placed over the area for no more than 15 minutes at a time. Never place ice directly on to your skin, as this can cause frostbite. Use a tea towel to wrap around and protect the skin.
- If it is painful, you may want to consider taking painkillers.
Is there anything I need to look out for?
In most cases, the injury is minor and does not need follow up or treatment. However, in a small number of cases, the injury to your skin is more severe and you will need to seek medical attention.
If you experience any of the following symptoms, you should attend your local Emergency Department and take this leaflet with you:
- The pain becomes more severe and your usual pain relief does not control the pain.
- There is increased swelling to the area.
- There is a change in sensation to the area or you get ‘pins and needles’.
- The skin changes colour.
- There is ulceration or blistering of the skin around the affected area.
