What Is Radio Frequency Ablation?
Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat varicose veins and chronic venous insufficiency. It uses controlled heat generated by radiofrequency energy to close off diseased veins, redirecting blood flow to healthier veins.
What Preparation Is Required?
Preparation is simple. You may be asked to:
- Avoid applying lotions or oils to your legs on the day of treatment
- Wear loose, comfortable clothing
- Stay well-hydrated and eat a light meal before your appointment
- Avoid caffeine on the day of your appointment
Your provider will give you any additional instructions prior to your procedure.
Can I Take My Current Medications?
Most medications can be continued as usual. Be sure to inform your provider if you are taking blood thinners or medications that affect circulation.
What Happens During Radiofrequency Ablation?
The procedure is performed using local anesthesia. A small catheter is inserted into the affected vein using ultrasound guidance. If you would prefer to be asleep or sedated during the procedure, please inform your doctor as soon as possible so appropriate arrangements can be made.
Radiofrequency energy is then delivered through the catheter, gently heating and sealing the vein closed. While the procedure itself usually takes about 5 minutes, you should plan for a total visit time of one to two hours to allow for preparation, waiting, and recovery.
Patients usually experience minimal discomfort and remain awake throughout.
What If the Procedure Treats the Problem Vein?
Once the treated vein is closed, blood is naturally rerouted to healthier veins. Over time, the treated vein is absorbed by the body, improving both symptoms and appearance.
What Happens After the Procedure?
After treatment:
- You will be asked to walk immediately
- Compression stockings may be worn for a period of time
- Most patients return to normal activities the same day
You may experience mild bruising or tightness along the treated vein, which typically resolves quickly.
If you need to travel for more than 2 hours at a time during the week after your procedure, please let your doctor know. Special instructions may be provided based on your individual circumstances.
What Are the Possible Complications?
RFA is a safe and effective treatment. Rare complications may include:
- Bruising or discomfort
- Skin irritation or burns
- Nerve irritation
- Blood clots
Contact your provider if you experience severe pain, swelling, or redness.
