Radiofrequency ablation is a procedure in which heat is used to treat certain kinds of lesions. We use RFA most commonly for benign bone growths such as an osteoid osteoma.
Using a CT scan for guidance, a radiologist places a special hollow needle into the area of bone that requires treatment. Sometimes the doctor first biopsies the bone: a small piece is removed and sent to a laboratory for analysis.
Next, the doctor threads a tiny heating probe through the middle of the special needle. The probe is insulated, except for at its tip. A machine attached to the probe transmits heat to the tip, and the heated tip is used to destroy the tumor or lesion. The tumor or lesion is not removed; over time it will be replaced with scar tissue.
No. Your child will be given either intravenous sedation or general anesthesia.
One to two hours.
Most children immediately feel less pain after the procedure. If the needle-insertion site hurts, you may give your child over-the-counter pain medication.
The procedure is considered low-risk. However, potential complications include:
Your child will be able to go home on the same day. We will bring your child to the recovery area after the procedure. Once your child is awake and able to keep liquids down, you will be able to take him or her home.
Leave the bandage on for 24 hours. Then you may remove the clear bandage and gauze; do not remove the Steri-Strips® (white strips). If they haven’t fallen off after seven days, you may remove them.
Keep the site completely dry for the first 24 hours. After 24 hours, your child may have a sponge bath or shower, but continue to keep the area dry. (Keep water from the shower from falling directly on the entrance site.) Do not submerge the site in water (bath or pool) until the Steri-Strips have fallen off.
Your child can resume most activities the day after the procedure. Sometimes weight-bearing activities such as heavy lifting must be restricted. Please ask the doctor or other member of the Interventional Radiology team about returning to sports or strenuous activity, as this may depend on the area that was treated.
