What is an image-guided drainage? 

It is a procedure to remove a collection of fluid from an organ or area within the body.  

On arrival in the Imaging Department, you will be asked to change into a hospital gown. You will be taken into the procedure room where the examination will be explained to you by the Consultant Radiologist, and you may ask any questions that you may have about the scan.  

The procedure is performed under local anaesthetic as a day case – patients will not need to undergo a general anaesthetic. You will be required to lie in a position which best gives access to the fluid collection. Images will be taken to best visualise the collection, either using CT or ultrasound, depending on what is the most appropriate for your collection. 

The skin is cleaned with an antiseptic and then numbed with a local anaesthetic. Once this has taken effect, a drainage needle will be inserted into your skin. You may feel pressure but should not feel pain. 

Small collections or fluid may be aspirated through the catheter, and the catheter removed altogether. For larger collections, it may be necessary to place a larger drainage tube into the collection and attach it to the skin with a special dressing so that the fluid can drain over hours/days. Should this be the case, this will be discussed with you prior to your appointment. 

After the procedure 

You be taken back to the ward for monitoring. If you experience any pain after the procedure, paracetamol may be taken to alleviate any discomfort.  

How long will the procedure take? 

The appointment will last approximately 30–60 minutes; however, your post-procedure rest time may vary depending on the type of drainage undertaken. Please allow a few hours in the Hospital.
