This is a minimally invasive percutaneous treatment which is used to treat large benign thyroid swellings (goitre). The procedure is performed under aseptic conditions in the angiography suite. During the procedure, local anaesthesia (pain killer) is injected into the skin at the access site to prevent discomfort. An injection of a mild sedative is also given to ensure that you are comfortable and relaxed during the procedure.

A special needle which generates heat at its tip (RFA probe) is placed in the goitre under Ultrasound guidance and the heat is used to burn and shrink the goitre. This is ideal for patients with large thyroid swellings which appear unsightly.
