ClosureFast in Singapore
Radiofrequency Treatment for Varicose Veins and Venous Reflux
ClosureFast is a specialised radiofrequency catheter system used for the minimally invasive treatment of selected veins affected by venous reflux.
The system delivers controlled radiofrequency energy to the inside of the affected vein. The resulting heat causes the vein to close, allowing blood to redirect through healthier veins. ClosureFast is therefore a radiofrequency ablation technique rather than a separate category of treatment.
At the Supreme Vascular and Interventional Clinic, treatment is planned according to your symptoms, ultrasound findings, vein anatomy and individual treatment goals.
Care is led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist, providing specialist vascular expertise from the brain to the body and continuity of care under one roof.

What Is ClosureFast?
ClosureFast is a specialised catheter used to perform radiofrequency ablation (RFA) for selected veins affected by venous reflux.
Varicose veins can develop when valves within the veins become weak or damaged. Instead of directing blood efficiently back towards the heart, blood can flow backwards and pool within the affected vein.
This is known as venous reflux.
ClosureFast uses controlled radiofrequency energy to heat the vein wall. The treated vein closes and blood is redirected through healthier veins.
Over time, the body naturally processes the closed vein.
How Does ClosureFast Work?
Closing the Faulty Vein Using Radiofrequency Energy
An ultrasound examination is first used to identify the affected vein and map the pattern of venous reflux.
A thin ClosureFast catheter is inserted into the vein through a small access point. The catheter is positioned within the targeted section of the vein under ultrasound guidance.
Radiofrequency energy is delivered through the catheter to heat the vein wall in controlled treatment segments.
The heat causes the vein wall to contract and the treated vein to close. The catheter is removed once treatment is complete. Blood then continues to flow through healthier veins.
When Might ClosureFast Be Recommended?
ClosureFast may be considered when ultrasound confirms that an underlying vein is contributing to venous reflux and symptomatic varicose veins.
Your specialist will consider:
- Your symptoms
- The appearance and extent of your varicose veins
- Ultrasound findings
- The location of venous reflux
- The anatomy of the affected vein
- Your medical history
- Previous vein treatments
- Your treatment goals
- Whether another treatment may be more appropriate
Not every varicose vein requires treatment, and ClosureFast is not suitable for every patient.
A specialist assessment and ultrasound evaluation are important before treatment is recommended.
Potential Benefits of ClosureFast
Minimally Invasive Radiofrequency Treatment
For appropriately selected patients, ClosureFast may provide several potential benefits.
Minimally Invasive
Treatment is performed through a small catheter entry point rather than surgically removing the vein.
Controlled Radiofrequency Energy
The catheter delivers controlled thermal energy to the targeted vein.
Ultrasound Guided
Imaging allows the specialist to identify the affected vein and guide the catheter accurately.
Treats the Underlying Refluxing Vein
The treatment targets the faulty vein responsible for abnormal blood flow rather than simply treating visible surface veins.
Established Radiofrequency Approach
ClosureFast is a specialised catheter system used to perform endovenous radiofrequency ablation.
Can Form Part of a Broader Treatment Plan
Additional treatments may be considered for remaining varicose veins depending on the patient's venous anatomy and treatment needs.
ClosureFast vs Other Varicose Vein Treatments
Understanding Your Options
ClosureFast is one approach to treating selected veins affected by venous reflux. The most appropriate treatment depends on your ultrasound findings, vein anatomy, symptoms, medical history and treatment goals.
| Treatment | How It Works |
|---|---|
| ClosureFast | Uses radiofrequency energy to heat and close the affected vein |
| EVLA | Uses laser energy to heat and close the affected vein |
| VenaSeal™ | Uses medical adhesive to seal the affected vein |
| Foam Sclerotherapy | Uses an injected sclerosant to close selected veins |
| Ambulatory Phlebectomy | Removes selected superficial varicose veins through small skin openings |
ClosureFast vs EVLA
Both ClosureFast and endovenous laser ablation are forms of thermal ablation. ClosureFast uses radiofrequency energy, while EVLA uses laser energy to generate heat within the affected vein.
Both treatments can be used to close selected refluxing veins. Your specialist can determine which approach is appropriate based on your individual venous anatomy and clinical circumstances.
ClosureFast vs VenaSeal™
ClosureFast and VenaSeal use different methods to close the affected vein. ClosureFast uses controlled radiofrequency heat. VenaSeal uses a medical adhesive to seal the vein without thermal energy.
Both are minimally invasive approaches for selected patients with venous reflux. The appropriate treatment depends on the patient's condition, vein anatomy and individual treatment goals.
What Are the Potential Risks and Limitations?
Understanding the Risks of ClosureFast
ClosureFast is minimally invasive, but like any medical procedure it carries potential risks.
Potential risks may include:
- Bruising
- Tenderness
- Swelling
- Temporary tightness along the treated vein
- Skin irritation
- Temporary changes in sensation
- Inflammation of the treated vein
- Rare nerve irritation or injury
- Recurrence or development of new varicose veins
- Need for additional treatment
Your individual risks depend on your medical history, vein anatomy and the treatment performed.
Your specialist will discuss the potential benefits, risks and alternatives before treatment.
Recovery After ClosureFast
What Can You Expect After Treatment?
Recovery varies between patients. The ClosureFast™ procedure (Radiofrequency Ablation or RFA) is a minimally invasive, outpatient treatment for chronic venous insufficiency and varicose veins. Because it relies on thermal energy delivered through a small catheter rather than surgical vein stripping, the recovery is fast and downtime is minimal. The treatment can last from 45-60 minutes. The actual radiofrequency heating process takes only 3 to 5 minutes (delivered in 20-second heating cycles per segment of the vein).
After ClosureFast treatment, you may be advised to:
- Walk regularly
- Avoid prolonged sitting or standing
- Follow access-site care instructions
- Take medication when required
- Wear compression if recommended
- Gradually return to normal activities
- Attend follow-up appointments
Temporary bruising, tenderness or tightness along the treated vein can occur during recovery.
Follow-up ultrasound may be recommended to assess the treated vein and surrounding circulation.
On the first day, you are encouraged to walk 15 to 20 minutes immediately following the procedure, after which you can safely drive home and resume light daily activities. Most patients are able to return to work and their normal daily routines the very next day.
Your specialist will provide personalised recovery instructions according to your treatment.
