Radiofrequency Ablation
(RFA)
Reasons for Procedure TOP
This procedure is used to destroy abnormal tissue that may be causing health problems. It may be used to treat:
- Tumors— to reduce their size
- Cardiac arrhythmias— to destroy areas of the heart that cause uneven or fast heartbeats
- Benign prostatic hyperplasia (BPH)—to remove extra prostate tissue
- Severe snoring and/or sleep apnea —to remove excess tissue at the back of the mouth and throat
- Severe nerve pain
- Varicose veins —removes veins that cause problems

Possible Complications TOP
Problems are rare, but all procedures have some risk. Your doctor will go over some problems that could happen such as:
- Excess bleeding

What to Expect TOP
Prior to Procedure
The care team may meet with you to talk about:
- Anesthesia options
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
- Fasting before the procedure, such as avoiding food or drink after midnight the night before
- Whether you need a ride to and from the procedure
- Tests that will need to be done before the procedure
Anesthesia
Local anesthesia will be used—the area will be numbed.
If this is done as part of another surgery, you may have:
- General anesthesia—you will be asleep, or
- Spinal anesthesia—you will be numb from the belly down
Description of the Procedure TOP
The exact steps will depend on where the tissue is located. A probe is applied to the area. Or the probe may be passed through a small tube to the area. Imaging such as a CT scan, ultrasound, or MRI scan will help guide the doctor to the area.
A small amount of electricity is passed through the tube. This heats and destroys the tissue. The probe may also be used to destroy other areas of tissue.
How Long Will It Take? TOP
About 10 to 60 minutes
Will It Hurt? TOP
Pain after the procedure depends on the location and amount of tissue. Medicine and home care help
Average Hospital Stay TOP
Some may leave the hospital on the same day. Others will need to stay overnight so the doctor can check them.
Post-procedure Care TOP
Most return to normal activities within a few days.

- Signs of infection, such as fever and chills
