VenaSeal Vein Glue Treatment in Singapore

VenaSeal is a branded medical cyanoacrylate adhesive system used to close selected superficial leg veins with symptomatic reflux. A catheter delivers the adhesive inside the vein under ultrasound guidance. Unlike radiofrequency or laser ablation, it does not use heat to achieve closure. Avoiding heat changes some aspects of treatment, but it does not make the procedure free of risk.

Who might consider vein glue?

The starting point is an assessment of varicose veins and venous reflux. A duplex scan should identify the vein responsible for the problem and assess the deep venous system. Symptoms, skin changes, vein anatomy, prior treatment and your preferences help determine whether intervention is worthwhile.

Glue can be one option when a suitable superficial trunk vein needs closure and a non-thermal approach is being considered. The decision should include your experience of medical adhesives and previous reactions, rather than focus only on fewer injections or recovery convenience. Dr Choong’s video article on scanning before treatment explains the assessment-first approach.

Why does allergy history matter?

The manufacturer lists previous hypersensitivity to its adhesive or cyanoacrylates as a contraindication. Acute superficial thrombophlebitis, migrating thrombophlebitis and acute sepsis are also listed contraindications. Tell the clinician about previous reactions, including any reaction after vein glue, wound glue or other adhesives, and provide details where possible.

An adhesive reaction history needs interpretation: different products contain different substances. Do not assume either that all glue allergies are identical or that an uneventful previous exposure rules out a future reaction. Suitability must be assessed against the actual product and your history.

What does the treatment involve?

After local anaesthetic at the access site, the specialist positions a catheter in the selected vein using ultrasound. Medical adhesive closes the vein internally. It remains in the treated vein; this is not a removable skin dressing. Thermal-ablation-style anaesthetic injections along the vein are generally not required for the glue closure itself.

Visible surface branches may need a separate approach, such as microphlebectomy or sclerotherapy. The proposed plan should identify whether branch treatment is included, deferred or unnecessary. The number of treatment steps depends on the findings, not on the brand name.

What complications are possible?

Inflammation, tenderness or redness can occur along the vein. Hypersensitivity reactions, including serious allergic reactions, are possible; an inflammatory reaction and an allergy may need different assessment. Persistent or worsening redness, itching, swelling, pain, fever or discharge should be reported rather than labelled as normal healing at home.

Other possible problems include bleeding, bruising, infection, skin discolouration, local tissue reactions, vein injury and DVT or pulmonary embolism. A foreign-material reaction can occasionally require further treatment. Closing the target vein does not guarantee complete symptom relief or prevent every future varicose vein.

How does glue compare with other options?

Thermal ablation avoids leaving adhesive but uses heat and protective local anaesthetic around the vein. Foam sclerotherapy uses a different chemical approach. Open surgery physically removes selected veins. These methods address overlapping but not identical situations; none is automatically the best choice for every patient.

Advice, activity measures, appropriate compression or observation remain reasonable in some circumstances. Ask which problem treatment is expected to improve and what is likely to happen if you decide against a procedure for now.

What should I expect afterwards?

Aftercare depends on the extent of treatment and any additional procedures. Some patients do not need compression after glue closure alone, while others may benefit from it. Ask for your own instructions on walking, work, exercise, travel and follow-up rather than assume a universal “no stockings” or “no downtime” rule.

Follow-up reviews symptoms and any suspected reaction or clot. New marked leg swelling requires prompt assessment. Breathing difficulty, facial or throat swelling, collapse, or chest pain with breathlessness needs emergency help: call 995 in Singapore.

Common questions

Is VenaSeal a name for every glue treatment?

No. It identifies a particular system. Ask which product is proposed and how its indications and risks apply to you.

Will every visible vein disappear?

No result can be promised. Discuss residual branches, skin changes and the possibility of further treatment before deciding.
