Cyanoacrylate Glue Treatment for Varicose Veins and Recovery Time
Cyanoacrylate glue treatment is a minimally invasive option for treating varicose veins that differs from both traditional surgery and heat-based techniques. It is often discussed because recovery is typically straightforward, and compression stockings are not routinely required after the procedure.
For people comparing treatment options, it is helpful to understand how this approach works, the expected recovery timeline, and its limitations. Clear information allows patients to weigh practical factors such as comfort, aftercare, and suitability alongside clinical effectiveness.
This treatment is most commonly known in the UK as VenaSeal and is used to close faulty superficial veins that contribute to varicose veins and related symptoms.
Cyanoacrylate Glue Treatment
Cyanoacrylate glue treatment is described as non-thermal and non tumescent. This means it does not use heat to close the vein and does not require multiple injections of dilute local anaesthetic along the length of the leg.
The procedure has been assessed by the National Institute for Health and Care Excellence and is supported under Interventional Procedures Guidance IPG670. NICE states that the evidence supports its use for treating varicose veins, provided that standard arrangements for clinical governance, consent, and audit are in place.
In clinical practice, cyanoacrylate glue closure is used to treat incompetent superficial veins, most commonly the great saphenous vein, which is a frequent source of varicose veins in the legs.
NICE Pathway
NICE guidance for varicose vein management sets out a treatment sequence for people with confirmed truncal reflux. Endothermal ablation is usually recommended first. If this is unsuitable, ultrasound-guided foam sclerotherapy may be considered. Surgery is reserved for cases where less invasive options are unsuitable.
Cyanoacrylate glue closure is included within the NICE interventional procedure guidance rather than replacing this pathway. This distinction is important for patients, as it explains why glue treatment may be discussed as an option but is not always the default recommendation.
Procedural Principles
The procedure is carried out under ultrasound guidance. A small catheter is introduced into the affected vein through a tiny skin puncture, usually around the knee or lower thigh.
Once positioned correctly, small amounts of medical cyanoacrylate adhesive are delivered inside the vein. Gentle pressure is applied to bring the vein walls together, thereby allowing the adhesive to seal the vein.
After closure, blood is redirected through healthy veins. Over time, the treated vein becomes fibrosed and is gradually absorbed by the body.
Anaesthetic Requirements
Cyanoacrylate glue treatment usually requires a single injection of local anaesthetic at the catheter entry point. This contrasts with endovenous laser ablation and radiofrequency ablation, which typically require multiple injections along the vein length to protect surrounding tissues from thermal injury.
For some patients, particularly those sensitive to injections, this difference can be a relevant factor when comparing treatments.
Recovery Time and Daily Activities
Recovery following cyanoacrylate glue treatment is generally uncomplicated. Patients are usually encouraged to walk shortly after the procedure, often for ten to twenty minutes, to promote circulation.
Most people return to normal daily activities on the same day or the following day. Desk-based work is commonly resumed immediately. More physically demanding activity, including gym exercise, is often delayed for several days, depending on comfort and clinical advice.
It is common to experience local tightness or tenderness along the treated vein during early healing. This typically resolves as the vein closes and inflammation subsides.
Compression Stockings After Treatment
Compression stockings are not routinely required after cyanoacrylate glue treatment. This differs from thermal ablation and surgical procedures, in which compression is often recommended.
NICE guidance also notes that if compression is used following interventional treatment, it should not usually be continued for longer than seven days. Practice may vary, and in selected cases, a clinician may still advise compression based on symptoms or vein pattern.
Side Effects and Potential Risks
All medical procedures carry some risk. The most commonly reported side effect of cyanoacrylate glue treatment is a local inflammatory reaction along the treated vein. This may present as redness, tenderness, firmness, or a cord-like sensation. It is often described as phlebitis and is usually managed with simple anti-inflammatory medication if appropriate.
Allergic reactions to cyanoacrylate are uncommon but recognised. Patients should also be aware that the adhesive remains permanently within the sealed vein, encapsulated by surrounding tissue.
Other potential risks include bruising, infection, nerve irritation, and deep vein thrombosis. These complications are uncommon, and serious adverse events are rare when treatment is performed following appropriate assessment and technique.
NHS Availability
Although cyanoacrylate glue treatment is NICE approved, it is not routinely commissioned by the NHS. NHS funded varicose vein treatment is usually limited to patients with more advanced disease, such as skin damage, ulceration, or bleeding.
Where treatment is offered, endovenous laser ablation or radiofrequency ablation are more commonly used due to established service pathways and cost considerations. Local commissioning criteria vary between Integrated Care Boards.
Private Treatment
Cyanoacrylate glue treatment is therefore most often accessed through private healthcare in the UK. Availability, follow-up arrangements, and costs vary between providers.
As a general guide, private treatment costs typically range from £2,500 to £3,500 per leg, depending on vein anatomy, the extent of treatment required, and whether consultations and follow-up ultrasound scans are included.
Requirement Of Duplex Ultrasound
Duplex ultrasound scanning is essential before any varicose vein treatment. It confirms the presence of venous reflux, identifies the source vein, and maps vein anatomy.
For glue treatment, ultrasound also confirms that the vein is suitable for catheter delivery and helps avoid treating surface veins alone when deeper reflux is driving symptoms. This approach aligns with NICE recommendations for diagnosis and treatment planning.
Comparison With Other Varicose Vein Treatments
Cyanoacrylate glue treatment is one of several effective options for treating varicose veins. Each approach has advantages and limitations, and suitability depends on vein anatomy, symptoms, and patient preference.
| Feature | Cyanoacrylate Glue (VenaSeal) | Endothermal Ablation (EVLA or RFA) | Ultrasound Guided Foam Sclerotherapy | Surgery (Ligation and Stripping) |
|---|---|---|---|---|
| Typical Target Vein | Straight truncal veins such as the great saphenous vein | Truncal reflux veins | Selected truncal or tributary veins | Truncal veins with extensive varicosities |
| Energy Or Agent Used | Cyanoacrylate adhesive | Heat energy | Sclerosant foam | Surgical removal or disconnection |
| Anaesthetic Pattern | Usually one local injection | Multiple local injections | Minimal local anaesthetic | General or regional anaesthetic |
| Compression After Treatment | Not routinely required | Often advised | Often advised | Often advised |
| Return To Normal Activity | Same day or next day | One to three days | One to three days | One to two weeks |
| Common Early Effects | Inflammation or tenderness | Bruising and tightness | Bruising and staining | Bruising and wound discomfort |
| NICE Position | IPG supported under governance | First line in CG guidance | Used if endothermal unsuitable | Used if other options unsuitable |
Patient Suitability and Limitations
Cyanoacrylate glue treatment may be suitable for patients with straight truncal vein reflux that can be catheterised. It may also be considered for individuals who are unable to tolerate compression stockings or who prefer a non-thermal approach.
It may not be appropriate for patients with very tortuous veins or a known allergy to cyanoacrylates. These factors are identified during ultrasound assessment.
Assessment and Decision Making
Treatment choice should be based on symptoms, clinical findings, ultrasound results, and individual preference. A balanced discussion of all suitable options supports realistic expectations and informed consent.
VenaSeal From Vein Solutions
VenaSeal is among the treatment options available at Vein Solutions. Assessment includes clinical review and duplex ultrasound to confirm suitability and determine whether glue closure or an alternative method is more appropriate.
Vein Solutions provides treatment in a regulated clinical setting, allowing patients to discuss recovery expectations, potential risks, and alternatives before making a decision.

FAQS
Is cyanoacrylate glue treatment safe?
Cyanoacrylate glue treatment has been assessed by NICE and is considered safe and effective when used with appropriate clinical governance, consent, and follow-up. As with all medical procedures, it carries risks that should be discussed during the assessment.
Is cyanoacrylate glue treatment available on the NHS?
Although NICE approved, cyanoacrylate glue treatment is not routinely funded by the NHS. NHS treatment for varicose veins is usually reserved for people with more advanced disease, such as skin damage or ulcers, and commonly uses laser or radiofrequency treatment instead.
Does the glue stay in the body?
Yes. The cyanoacrylate adhesive remains permanently within the treated vein. The vein becomes sealed and is gradually surrounded by scar tissue. This typically does not cause problems, but patients should be aware of it before treatment.
Will I need compression stockings after treatment?
Compression stockings are not routinely required after cyanoacrylate glue treatment. In some cases, a clinician may still recommend stockings for comfort or symptom control, but this is not standard practice.
Is the procedure painful?
Most people report minimal discomfort. Usually, only one local anaesthetic injection is needed at the entry point. Some tenderness or tightness along the treated vein can occur afterwards and usually settles over time.
How long does recovery take?
Many people return to normal daily activities on the same day or the next. Walking is encouraged straight away. More strenuous exercise is often delayed for a few days, depending on comfort and clinical advice.
Are there side effects?
The most common side effect is a local inflammatory reaction along the treated vein, which may cause redness, tenderness, or firmness. This often settles with time and may be treated with anti-inflammatory medication if appropriate. Bruising and infection are uncommon.
Can everyone have glue treatment?
No. Glue treatment is not suitable for all vein patterns. Very twisted veins or a known allergy to cyanoacrylates may make this option unsuitable. Duplex ultrasound scanning is needed to confirm suitability.
Will treating one vein stop all varicose veins from coming back?
Treating a faulty vein improves symptoms and appearance related to that vein. However, venous disease can progress over time, and new veins may develop. Follow-up and long-term vein care remain essential.
Is ultrasound assessment necessary?
Yes. Duplex ultrasound is essential before any varicose vein treatment. It confirms the source of reflux and helps ensure the most appropriate treatment is chosen.
