Radiofrequency Ablation (RFA) in Singapore
Minimally Invasive Radiofrequency Treatment for Selected Conditions
Radiofrequency Ablation (RFA) is a minimally invasive treatment that uses controlled radiofrequency energy to heat and treat targeted tissue or nerves.
The technique can be used for different medical conditions depending on the location and purpose of treatment. In pain management, RFA may be used to target selected nerves that are responsible for transmitting pain signals. In other applications, controlled thermal energy can be used to treat abnormal tissue, such as selected thyroid nodules or incompetent veins associated with varicose veins.
At the Supreme Vascular and Interventional Clinic, care is led by Dr Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist. The appropriate RFA technique is selected according to the condition being treated, the anatomy involved and the patient's individual circumstances.
With expertise spanning the brain and body, our clinic in Singapore provides specialist-led vascular and interventional assessment, minimally invasive treatment and continuity of care under one roof.

What Is Radiofrequency Ablation?
Radiofrequency Ablation is a minimally invasive technique that uses radiofrequency energy to generate controlled heat at a targeted area.
Depending on the application, the energy can be used to:
- Target selected nerves responsible for transmitting pain
- Treat selected abnormal or unwanted tissue
- Close incompetent veins
- Reduce the volume or activity of selected thyroid nodules
RFA is performed differently depending on the condition being treated. Imaging such as ultrasound or other appropriate imaging techniques may be used to accurately guide the treatment.
How Does Radiofrequency Ablation Work?
A specialised probe or catheter is positioned at the area being treated using image guidance. Controlled radiofrequency energy is then delivered to the targeted tissue or nerve.
The effect of the treatment depends on its purpose. For pain management, RFA is used to interrupt pain signalling from selected nerves. For conditions such as thyroid nodules or varicose veins, the controlled thermal energy is used to treat the targeted tissue or vein.
The specific technique, equipment and treatment settings vary according to the condition and anatomy being treated.
Radiofrequency Ablation Treatments at the Supreme Vascular and Interventional Clinic
What Conditions Can Be Treated With RFA?
RFA has applications across several areas of medicine. At the Supreme Vascular and Interventional Clinic, it may be considered for selected patients with:
Pain Conditions
RFA can be used to target selected nerves involved in transmitting pain signals. It may be considered for certain types of:
- Knee pain
- Shoulder pain
- Back pain
- Neck pain
- Joint-related pain
- Nerve-related pain
- Other selected chronic pain conditions
Thyroid Nodules
RFA can be used to treat selected benign thyroid nodules by applying controlled heat to the nodule, with the aim of reducing its volume and associated symptoms.
Varicose Veins
RFA is also used as an endovenous treatment for selected varicose veins caused by incompetent or refluxing veins. A catheter delivers controlled thermal energy to the affected vein, causing it to close and allowing blood to be redirected through healthier veins.
RFA for Selected Tumours
Radiofrequency ablation may be used in interventional oncology to treat selected tumours using controlled heat. A specialised probe is guided into the tumour using imaging, and radiofrequency energy is delivered to heat and destroy the targeted tissue.
RFA may be considered for selected tumours depending on their type, size, location and relationship with nearby organs and structures. It may be used as part of a broader cancer treatment strategy or when surgery is not the most appropriate option.
Radiofrequency Ablation for Pain Management
Targeted Treatment for Selected Pain Conditions
In pain management, RFA is used to target specific nerves that contribute to pain transmission.
It does not directly repair or remove the underlying joint or tissue problem. Instead, the objective is to reduce pain signalling from selected nerves supplying the affected area.
RFA may be considered for appropriately selected patients with persistent pain affecting areas such as the knee, shoulder, back or neck.
Knee and Shoulder Pain
For selected patients with chronic knee or shoulder pain, RFA may target nerves supplying the affected joint.
The treatment may be considered when pain persists despite conservative treatment or when other interventions have not provided sufficient relief.
Back and Neck Pain
RFA may be considered for selected spinal or facet-joint-related pain where specific nerves have been identified as contributing to the symptoms.
Image guidance is used to accurately identify and treat the targeted nerves.
Nerve-Related Pain
Where a specific nerve is contributing to pain, diagnostic nerve blocks may sometimes be used to help determine whether RFA is appropriate.
The suitability of RFA depends on the underlying cause and pattern of pain.
RFA for Thyroid Nodules
RFA can be used to treat selected benign thyroid nodules without conventional surgery.
A specialised probe is inserted into the thyroid nodule under ultrasound guidance. Controlled radiofrequency energy is delivered to the targeted tissue, causing thermal treatment of the nodule. Over time, the treated nodule can decrease in size. RFA may be considered for selected patients who have symptomatic or enlarging benign thyroid nodules.
RFA for Varicose Veins
RFA is an established endovenous treatment for selected varicose veins caused by venous reflux.
A thin catheter is inserted into the affected vein under ultrasound guidance. Radiofrequency energy is delivered along the vein, causing it to close. Blood is then redirected through healthier veins.
The suitability of RFA depends on the underlying venous anatomy and pattern of reflux.
Potential Benefits of Radiofrequency Ablation
Minimally Invasive Treatment Using Controlled Energy
For appropriately selected patients, RFA may offer several potential benefits.
Minimally Invasive
RFA is performed through a small access point rather than conventional open surgery.
Image-Guided
Ultrasound or other imaging techniques can help accurately position the probe or catheter and target the intended treatment area.
Controlled Treatment
Radiofrequency energy can be delivered in a controlled manner to the targeted tissue, vein or nerve.
Different Medical Applications
RFA can be used for selected pain conditions, benign thyroid nodules and venous disease.
Can Be Tailored to the Condition
The technique, treatment area and energy delivered can be adjusted according to the condition and individual anatomy.
Generally Shorter Recovery
Because RFA is minimally invasive, recovery may be shorter than conventional surgical approaches, depending on the procedure performed.
What Are the Potential Risks and Limitations?
Understanding the Risks of RFA
RFA is generally well tolerated, but potential risks vary considerably depending on what is being treated.
These may include:
- Temporary pain or discomfort
- Bruising or swelling
- Temporary numbness or altered sensation
- The possibility of requiring additional treatment
The specific risks associated with RFA for pain, thyroid nodules and varicose veins are different. These will be discussed as part of the assessment and treatment planning process.
Recovery After Radiofrequency Ablation
What Can You Expect After Treatment?
Recovery varies depending on the condition being treated and the type of RFA performed.
Many procedures involve a relatively short recovery period, although patients may receive specific instructions regarding:
- Physical activity
- Care of the treatment or access site
- Pain management
- Monitoring for swelling or other symptoms
- Follow-up imaging or appointments
Some RFA treatments can be performed as day procedures, while others may require additional observation depending on the clinical circumstances.
Your recovery plan will be tailored to the treatment you receive. Your specialist will provide personalised aftercare instructions based on your procedure.
Recovery After Radiofrequency Ablation for Varicose Veins
You can usually walk and go home immediately after the procedure. Most people resume normal light activities within 1–2 days. Symptom relief (less aching/heaviness) is often felt within a few days to a week. Complete visible disappearance or shrinking of the vein usually takes about 4 to 6 weeks as your body reabsorbs the sealed tissue.
Recovery After Radiofrequency Ablation for Thyroid Nodules
It is performed using local anesthesia, and you can usually return home after an hour of observation. Most patients return to normal activities the next day. Unlike veins, which seal shut quickly, a treated thyroid nodule shrinks slowly as the body cleans up the ablated tissue. You can expect a 50% to 80% size reduction over 6 to 12 months.
