A Comprehensive Guide to Varicose Vein Treatment

Varicose veins develop when the valves inside them don’t work properly, causing blood to pool instead of flowing smoothly back to the heart. Luckily, there are many effective, minimally invasive treatments available today, such as Endovenous Radiofrequency Ablation (RFA) and Clarivein Mechanochemical Ablation (MOCA).

Varicose veins are those twisted, bulging veins that often appear blue or dark purple, typically on the legs. These veins develop when the valves inside them don’t work properly, causing blood to pool instead of flowing smoothly back to the heart. This can lead to discomfort, swelling, and more serious health problems if left untreated. Luckily, there are many effective treatments available today.

Understanding Varicose Veins

Varicose veins result from a condition called venous insufficiency. This happens when the valves in your veins fail, allowing blood to accumulate. Various factors contribute to this condition, including genetics, aging, prolonged standing or sitting, obesity, and pregnancy. People with varicose veins often experience symptoms that range from cosmetic concerns to pain, swelling, and even ulcers.

Current Treatment Options

Endovenous Radiofrequency Ablation (RFA)

One of the modern methods to treat varicose veins is Endovenous Radiofrequency Ablation (RFA) . During this procedure, a thin catheter is inserted into the vein under ultrasound guidance. Radiofrequency energy is then used to heat and seal the vein, redirecting blood flow to healthier veins. This technique is minimally invasive, has a short recovery time, and can be done as an outpatient procedure, making it a highly effective option.

Clarivein Mechanochemical Ablation (MOCA)

Another innovative treatment is the Clarivein Mechanochemical Ablation (MOCA), which uses a rotating catheter and a sclerosant solution to collapse and seal the vein without heat. This reduces the risk of thermal injury. MOCA is particularly suitable for sealing veins below the knee, offering less pain and a quicker recovery.

Ultrasound-Guided Foam Sclerotherapy

Ultrasound-Guided Foam Sclerotherapy involves injecting a foam sclerosant into the vein under ultrasound guidance. The foam causes the vein to close and gradually disappear. This method is minimally invasive and effective for smaller veins, providing a quick and simple solution.

VenaSeal (Medical Adhesive or “Super Glue”)

VenaSeal is another advanced treatment option where a medical adhesive is used to seal the vein. The body then absorbs the sealed vein over time. This procedure is minimally invasive, does not require compression stockings after treatment, and allows for a quick recovery.

Ambulatory Phlebectomy

Ambulatory Phlebectomy is a procedure where small incisions are made to remove varicose veins close to the skin surface. This method is effective for immediate removal of big bulging surface veins, leaves minimal scarring, and is usually performed at the same time as the venous reflux procedure.

Compression Therapy

Compression therapy involves wearing compression stockings to improve blood flow and reduce symptoms. It is also used post-operatively for 2-4 weeks to reduce bruising and aid in a faster recovery. Do note that the use of compression stockings alone does not definitively treat the underlying venous reflux.

Lifestyle Changes

Making certain lifestyle changes can significantly improve vein health and help manage varicose veins. Regular exercise is crucial as it improves circulation. Maintaining a healthy weight reduces the pressure on your veins, and avoiding prolonged periods of standing or sitting helps prevent blood from pooling in the legs.

Post-Treatment Care

After undergoing treatment for varicose veins, proper post-treatment care is essential for optimal recovery. Wearing compression stockings can help reduce swelling and aid in recovery. Elevating your legs can also improve circulation and reduce swelling. Staying hydrated and maintaining a balanced diet supports overall vein health. Regular follow-ups with your healthcare provider are important to monitor your progress and prevent recurrence.

Risks and Considerations

While modern treatments for varicose veins are generally safe, there are potential risks to be aware of. These include infection at the treatment site, rare occurrences of nerve damage, recurrence of varicose veins, and allergic reactions to sclerosants or adhesives. Your vascular surgeon will have a more detailed discussion with you about this prior to any procedure.

Does MediSave Cover Varicose Vein Treatment in Singapore?

MediSave may be used for varicose vein treatment in Singapore when the condition is medically indicated, such as when symptoms and duplex ultrasound confirm venous reflux. Minimally invasive treatments such as RFA, ClariVein, VenaSeal, ultrasound-guided sclerotherapy or mini phlebectomies may be claimable when performed as an approved surgical or day surgery procedure (with an appropriate TOSP code). Purely cosmetic spider vein treatment is generally not MediSave-claimable.

Do Compression Socks Help Restless Legs? When They Work and When They Don’t

Compression socks may help restless or uncomfortable legs when symptoms are linked to venous pooling, swelling, varicose veins, or chronic venous insufficiency. They are not a cure for true neurological Restless Legs Syndrome, but they can reduce heaviness, aching, crampy tightness, and night-time discomfort in selected patients. If restless legs come with swelling, visible veins, or ankle skin changes, a vascular assessment may be useful.

What Happens to Varicose Veins After Treatment?

After varicose vein treatment, the diseased vein is usually closed, sealed, or removed so blood can
reroute through healthier veins. The treated vein may still be visible or feel firm at first, but over weeks
to months, the body gradually breaks it down. Symptoms such as heaviness, aching, and swelling
often improve earlier than the visible appearance. Full cosmetic results take time, and some patients
may need staged treatment for remaining surface veins or spider veins.

Can a Varicose Vein Burst? What to Do If It Bleeds

Yes, a varicose vein can burst and bleed, especially when the vein is large, under pressure, and covered by thin or fragile skin. If this happens, lie down, raise the leg, and apply firm direct pressure over the bleeding point with a clean cloth or dressing. Even if the bleeding stops, you should arrange an urgent vascular surgeon review because the underlying venous reflux may still be present, and bleeding can recur.

Why Are My Ankles Swollen? Common Causes, Hidden Risks, and When to Worry

Most ankle swelling is related to gravity and fluid pooling- often from prolonged standing/sitting, salty meals, weight gain, pregnancy, or vein-related pooling (chronic venous insufficiency). If swelling is persistent, worsening, associated with ankle skin itch/discolouration, or improves noticeably with leg elevation, venous reflux becomes the most likely culprit. If swelling is sudden and one-sided, painful, red/warm, or you have breathlessness or chest discomfort, seek urgent medical assessment.
