VenaSeal for Varicose Veins in Singapore Explained

Varicose Veins Treatment

If you’re dealing with varicose veins in your legs, you might be wondering if there’s a modern, less invasive solution. For many in Singapore exploring their options, VenaSeal can come up—but what exactly is it, and is it the right treatment for you?

At the Vascular and Interventional Clinic, our specialist vascular doctors have treated hundreds of patients with varicose veins, tailoring each treatment plan to the patient’s specific needs. Here, we break down everything you need to know about VenaSeal—from how it works to how it compares with other treatments.

WHAT is it

What Is VenaSeal Surgery?

VenaSeal is a non-surgical treatment for varicose veins that avoids heat or stripping of veins. Instead, it uses a medical adhesive to close problematic veins, redirecting blood flow to healthier ones. This positions it as a less painful and downtime-free solution for varicose vein

How Does VenaSeal Work?

VenaSeal involves the insertion of a tiny catheter into the affected vein. Through this, a small amount of medical adhesive is injected to seal the vein shut. Once sealed, blood naturally reroutes through healthy veins in your leg. Your body gradually absorbs the treated vein over time, typically within 6-12 months. The adhesive remains permanently in place, creating a durable seal that prevents the vein from reopening.This targeted approach means only the problematic vein receives treatment, leaving surrounding healthy tissue undisturbed.

Unlike heat-based procedures, VenaSeal doesn’t require tumescent anaesthesia, reducing discomfort and bruising.

Is VenaSeal Considered Surgery or a Minimally Invasive Procedure?

VenaSeal is not considered a surgery.

Unlike surgical vein stripping, which requires multiple incisions and general anaesthesia, VenaSeal requires only a single needle puncture—similar to having blood drawn. This minimally invasive procedure is performed under local anaesthesia in our clinic’s comfortable outpatient setting. Most patients walk out within an hour of treatment, resuming normal activities immediately. This stark contrast to surgical recovery, which can involve weeks of limited mobility, makes VenaSeal an attractive option for busy professionals and active individuals.

However, whilst minimally invasive, VenaSeal still requires expertise and precision. Our vascular specialists undergo specialised training to ensure optimal outcomes and patient safety throughout the procedure.

How Long Has VenaSeal Been Around?

VenaSeal received CE Mark approval in Europe in 2011 and FDA clearance in the United States in 2015.

It has been used in Singapore for several years, and it is a well-studied treatment. The technology continues evolving, with refinements in delivery systems and technique protocols enhancing patient comfort and treatment precision.

Our clinic stays current with these advances, ensuring you benefit from the most sophisticated VenaSeal techniques available.

VenaSeal vs. Other Treatments: Which Is Best?

Choosing between VenaSeal and alternative treatments depends on multiple factors including your vein anatomy, lifestyle requirements, and personal preferences. Each treatment option offers distinct advantages and limitations that merit careful consideration.

What is the difference between VenaSeal and sclerotherapy?

While both VenaSeal and sclerotherapy treat problematic veins, they serve fundamentally different purposes. 

VenaSeal treats the root cause by sealing larger faulty veins, while sclerotherapy focuses on smaller spider veins. Many patients combine both—VenaSeal first for underlying issues, followed by sclerotherapy for cosmetic results. The best choice depends on your vein size, symptoms, and treatment goals.

Key differences in features are as follows:

Feature VenaSeal Sclerotherapy
Primary Use
Treats larger varicose veins (venous insufficiency)
Treats spider veins & small varicose veins
Method
Medical adhesive (glue) seals veins
Chemical solution collapses veins
Treatment Approach
Addresses root cause (venous reflux)
Treats visible surface veins
No. of Sessions
Typically 1 session
Multiple sessions (usually 3-5)
Anaesthesia
Local anaesthetic
Usually none required
Procedure Time
30-60 minutes
15-30 minutes per session
Recovery Time
Immediate return to activities
1-2 days of reduced activity
Compression Stockings
Usually not required
Required (2-6 weeks)

Which is better?

Both VenaSeal and laser ablation (EVLA) are effective treatment options for varicose veins. However, patient experience and recovery differ considerably between these approaches.

EVLA uses heat energy to seal veins closed, requiring tumescent anaesthesia—multiple injections around the treated vein. This creates temporary numbness but can cause discomfort during administration. VenaSeal requires only single-point local anaesthesia, making the procedure more comfortable for needle-sensitive patients.

Post-treatment recovery favours VenaSeal clearly. Laser patients must wear compression stockings for 1-2 weeks and may experience bruising, swelling, or temporary skin discolouration. VenaSeal patients avoid compression requirements and typically experience minimal bruising.

“Better” depends on your priorities and circumstances. VenaSeal (glue) offers superior patient comfort and convenience, whilst laser ablation provides longer-established track record and potentially better insurance coverage. VenaSeal excels in patient experience metrics. 

The single-puncture approach, immediate return to activities, and elimination of compression stockings appeal to many patients. Business travellers, athletes, and parents with young children particularly value these conveniences. 

Laser ablation demonstrates excellent clinical outcomes with extensive long-term data. Some insurance providers show preference for laser treatment due to its established history and clinical evidence base. Anatomical considerations may influence choice too. 

Certain vein configurations respond better to specific treatments. Tortuous or superficial veins might favour VenaSeal’s precise adhesive delivery, whilst straight, deeper veins may suit laser energy distribution. The “best” treatment aligns with your specific needs, anatomy, and preferences. Our specialists evaluate these factors comprehensively, recommending the approach most likely to achieve your desired outcomes.

Who Is a Candidate for VenaSeal?

Sclerotherapy techniques have a good safety profile when performed by a qualified vascular specialist. But, like any medical procedure, it carries some risks and potential side effects.

Most side effects are mild and temporary, resolving without intervention as your body heals from the treatment. However, being aware of potential complications enables you to follow post-treatment instructions carefully and seek appropriate care if needed.

Who Should Not Use VenaSeal?

VenaSeal is not suitable for everyone. Key contraindications include:

  • Active infections near the treatment site
  • Pregnancy and breastfeeding
  • Deep vein thrombosis (DVT) history
  • Current blood clotting disorders
  • Severe peripheral artery disease
  • Known adhesive allergies (cyanoacrylate sensitivity is an absolute contraindication)
  • Very small vein diameters (less than 3mm cannot accommodate the catheter system)

Your specialist will assess circulation thoroughly and may recommend patch testing for adhesive sensitivity in uncertain cases. Alternative treatments like sclerotherapy often work better for smaller vessels or high-risk patients.

Can VenaSeal Treat Spider Veins or Recurrent Varicose Veins?

VenaSeal primarily targets larger varicose veins and their source vessels rather than spider veins. The catheter system requires adequate vein diameter—typically 3mm or larger—to function properly. Spider veins, measuring 1mm or less, fall outside VenaSeal’s intended application.

Recurrent varicose veins present varying challenges depending on previous treatment types. Patients with previous surgical stripping may have ideal anatomy for VenaSeal, as the main problematic veins remain accessible. However, those with previous thermal ablation may have scarring that complicates catheter placement.

Our specialists use advanced imaging to map your venous system comprehensively, identifying all treatable vessels and planning optimal treatment sequences. This thorough approach maximises long-term success whilst minimising treatment sessions.

Is VenaSeal Safe for Everyone?

While generally safe, VenaSeal should be used under the guidance of a vascular specialist.

A full clinical assessment, including duplex ultrasound, is necessary to determine suitability.

PROS & CONS

Benefits & Disadvantages of VenaSeal

Every medical treatment involves trade-offs between benefits and limitations. Here’s a balanced view of what you can expect from VenaSeal.

Single Puncture approach to Varicose Veins

Pros: Minimally Invasive, No Compression Stockings Needed

  • Single-puncture approach eliminates multiple incisions and reduces infection risks
  • No heat, so less pain and bruising
  • No need for multiple injections of local anaesthetic
  • Patients can typically return to normal activity on the same day
  • No need to wear compression stockings in most cases
Risks of VenaSeal: Allergic Reactions

Cons: Nerve Damage Risk, Cost, and Long-Term Effects

  • Higher upfront cost compared to laser
  • Possible risk of allergic reaction to the glue
  • Rare cases of phlebitis (inflammation) or nerve irritation
  • Long-term data is still being gathered compared to decades of laser use

Procedure & recovery

What to Expect: The VenaSeal Procedure & Recovery

Understanding the VenaSeal experience from procedure through recovery helps set appropriate expectations and reduces anxiety about treatment. Here’s a look at what the process involves and how soon you can get back on your feet.

Most patients report little to no pain during the treatment. Adhesive delivery creates no sensation whatsoever. Unlike thermal treatments that may cause burning sensations, VenaSeal’s mechanical closure process is completely painless. The entire treatment typically takes 30-45 minutes, with most time spent on preparation and positioning.

Recovery is rapid. Most patients resume normal activities immediately after treatment, including walking, driving, and working. The single puncture site typically heals within 24-48 hours. Many patients return to work the next day. Mild tenderness or bruising can occur but usually resolves within a few days.

VenaSeal’s greatest convenience advantage is eliminating compression stocking requirements. Unlike thermal ablation or surgical treatments requiring 1-2 weeks of tight compression, VenaSeal patients can avoid stockings entirely. This benefit particularly appeals to patients in Singapore’s tropical climate, where compression garments can be uncomfortable. The freedom from compression requirements allows normal clothing choices and activities immediately after treatment.

However, your doctor may still recommend them depending on your case.

“Permanent” requires qualification, however. VenaSeal permanently seals treated veins, but cannot prevent new varicose veins from developing in other locations. Venous disease often progresses over time, potentially affecting previously healthy veins years after treatment. The treated vein undergoes permanent structural changes. 

Your body gradually absorbs the sealed vein over 6-12 months, whilst the adhesive remains in place indefinitely. This process creates permanent elimination of the treated vessel. Success depends heavily on treating the correct veins initially. Comprehensive evaluation identifying all sources of venous reflux ensures optimal long-term outcomes. Incomplete treatment may result in continued symptoms from untreated vessels.

COSTS

Cost of VenaSeal and Is It Worth It?

Financial considerations play a crucial role in treatment decisions, especially for procedures that may not receive full insurance coverage. Let’s look at what to expect in Singapore.

How Much Does VenaSeal Cost?

The cost of VenaSeal in Singapore can vary depending on the severity of your vein condition.

According to the Ministry of Health’s fee benchmarks, the surgeon’s fee for VenaSeal typically ranges from $4,900 to $7,300

Treatment costs in Singapore vary based on the procedure type, clinic setting, and extent of treatment required. To give a sense of cost, the table below outlines how VenaSeal compares to other common vein treatments in terms of estimated surgeon’s fees.

Does Insurance or Medisave Cover VenaSeal?

Medisave coverage for Venaseal is available when the treatment is deemed medically necessary. Conditions like painful varicose veins with documented symptoms may qualify for partial coverage.

Private insurance coverage varies widely between policies and providers. Some comprehensive health insurance plans cover medically necessary vein treatments, whilst others exclude these procedures entirely or have specific limitations.

To qualify for insurance coverage, you typically need documentation of symptoms like pain, swelling, skin changes, or functional impairment rather than purely cosmetic concerns.

Pre-approval from insurance providers is recommended before proceeding with treatment to understand your coverage.

FAQs about VenaSeal

Once sealed, the treated vein becomes fibrotic and is gradually absorbed by the body over time. Blood naturally reroutes through healthier veins, improving circulation.

The cosmetic improvement develops gradually as the treated vein fades from view. Initially, you might see a firm cord beneath the skin where the vein was located. This cord softens and becomes less visible over several months as your body absorbs the vein tissue.

The risk of deep vein thrombosis with VenaSeal is extremely low. Nerve damage is also rare, especially since the procedure avoids thermal injury.

Blood Clot Risk (Very Low):

  • Lower risk than surgery: Superficial vein treatment carries much less risk than deep vein procedures
  • No deep vein impact: Sealed veins don’t affect critical circulation; deep veins remain unaffected
  • Preventive advantage: Adhesive seals veins permanently rather than creating clot-prone areas

Nerve Damage Risk (Extremely Rare):

  • Mostly temporary: Most reported symptoms resolve within weeks to months
  • Permanent damage: Extremely rare, typically associated with unusual anatomy
  • Risk management methods: Advanced ultrasound guidance and careful technique minimise risks

That said, every vascular treatment carries some risk, which your specialist will explain.

Determining whether VenaSeal represents your best treatment option requires comprehensive evaluation of multiple factors. Your specific anatomy, lifestyle requirements, medical history, and personal preferences all influence this decision.

VenaSeal is ideal for those seeking a fast, low-downtime solution with minimal discomfort. That said, each patient is different. At the Vascular and Interventional Clinic, we take a comprehensive look at your condition to recommend the best treatment—be it VenaSeal, laser, or another approach.
