Radiofrequency Ablation and Laser Treatment for Varicose Veins

Radiofrequency ablation (RFA) treats a faulty superficial vein by using controlled heat to close it from within. It is considered when backward blood flow, or reflux, contributes to varicose-vein symptoms or skin changes. The aim is to address a source of abnormal flow, rather than remove every visible vein. Blood returns through other functioning veins.

Who may benefit from radiofrequency ablation?

A duplex ultrasound maps the superficial veins, examines the deep veins and relates the findings to aching, heaviness, swelling or skin damage. A refluxing saphenous vein may be suitable for closure, but its course, depth and relationship to nearby nerves matter. A prominent vein or a scan result alone does not establish a need for treatment.

The consultation also considers previous clots or vein procedures, medicines, pregnancy, mobility and overall health. Watch Dr Choong’s explanation of why the scan comes before treatment. If symptoms are mild or have another cause, advice and observation may be more appropriate.

What does RFA involve?

A specialist introduces a catheter into the selected vein using ultrasound guidance. Local anaesthetic around the vein helps provide comfort and protect surrounding tissue while the catheter delivers heat. The vein is closed internally; it is not stripped out through the leg. The anaesthetic and care setting are discussed for the individual plan.

Bulging surface branches may need microphlebectomy or sclerotherapy, either during the same treatment episode or later. Knowing which veins each part of the plan addresses helps explain why closing one vein may not immediately change every visible branch.

How does endovenous laser ablation differ?

Endovenous laser ablation (EVLA), also called EVLT, uses laser energy rather than radiofrequency energy to generate heat inside the vein. Both belong to the thermal-ablation family and use imaging to guide treatment. Both require attention to nearby tissue and nerves.

The useful comparison is how each method fits your anatomy, symptoms and treatment goals. The word “laser” does not itself establish a better result, and a preference for one device should not replace an explanation of the proposed benefit and relevant risks.

What are the alternatives?

Walking, avoiding prolonged stillness, leg elevation and appropriately selected compression can help some symptoms. Compression does not repair faulty valves and needs assessment when arterial circulation is impaired. For intervention, alternatives include cyanoacrylate vein glue, foam injections and open vein surgery. Each has different practical requirements and limitations.

What risks should I understand?

Possible problems include bruising, discomfort, inflammation along the treated vein, altered skin sensation, nerve injury, skin staining, burns, infection or bleeding. Clot may extend towards a deep vein, or a DVT may occur. Pulmonary embolism is a serious possible complication. These risks are assessed alongside the expected benefit, including any personal clotting history.

A treated vein may reopen, and reflux can develop elsewhere. Successful closure on a scan does not guarantee that all swelling or discomfort will resolve.

What happens during recovery and follow-up?

Walking is commonly part of recovery, with individual advice about dressings, compression, exercise, work, driving and travel. Additional branch treatment and your medical history can change those instructions. Obtain a written plan rather than assume that a return-to-work claim applies to your job.

Follow-up assesses symptoms and any concern about closure or thrombosis; ultrasound timing depends on the procedure and risk profile. New marked swelling, worsening pain, fever or concerning skin changes need prompt advice. Sudden breathlessness, chest pain with breathlessness or collapse requires emergency help: call 995 in Singapore.

Common questions

Will I still need the vein?

The assessment checks whether the proposed target is a faulty superficial vein and whether other drainage is adequate. Previous thrombosis, deep-vein obstruction or potential future use of a vein can affect the plan.

Can both legs be treated together?

This is an individual decision. Ask how the extent of treatment would affect walking, support at home and clot-risk planning.
