Foam Sclerotherapy in Melbourne: A Practical Treatment Guide
Many people live with visible or uncomfortable leg veins for years. Although some seek treatment for cosmetic reasons, varicose veins can also cause aching, swelling, skin changes and, in more advanced cases, venous ulcers.
Most modern varicose vein procedures are minimally invasive and performed outside hospital. This guide explains foam sclerotherapy and how it compares with laser, radiofrequency and vein glue for people in Melbourne and regional Victoria.
Foam sclerotherapy involves injecting a foamed medicine, called a sclerosant, into a vein. The medicine irritates the vein lining, causing the vein to close and gradually become less visible. This is general information, not medical advice. Treatment suitability depends on an assessment by a registered doctor.
Your treatment options at a glance
Healthdirect lists sclerotherapy, laser or ablation therapy, and surgery among the main treatment options. Duplex ultrasound is commonly used to confirm the diagnosis and map blood flow. Conservative measures, including regular walking, leg elevation, weight management where relevant and graduated compression stockings, may also help relieve symptoms.
When a procedure is appropriate, the main options include:
Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA), which use heat inside the vein to seal it.
Ultrasound-guided foam sclerotherapy (UGFS), which closes veins using an injected medicine.
Cyanoacrylate glue closure, a non-thermal alternative that seals the vein with medical adhesive.
Microphlebectomy, in which bulging surface veins are removed through small incisions.
For confirmed truncal reflux, where faulty valves affect a main superficial vein, NICE recommends offering endothermal ablation first. Foam sclerotherapy may be considered when endothermal treatment is unsuitable, followed by surgery when foam is also unsuitable. During pregnancy, NICE advises against interventional treatment except in exceptional circumstances. Compression may instead be used for symptom relief.
Where foam sclerotherapy fits
Sclerotherapy can use either a liquid or a foam. Foam is created by mixing the sclerosant with a small volume of gas. This helps it displace blood and remain in contact with the vein wall. RadiologyInfo notes that foam sclerotherapy may be used to close larger superficial veins.
In practice, foam is commonly used for spider veins, reticular veins, small to medium tributaries branching from the main veins, and some recurrent veins after earlier treatment. Australian consumer medicine information for Aethoxysklerol, a polidocanol product, describes its use for certain varicose veins. It also stresses the importance of following compression and walking instructions after treatment.
Who is, and isn't, a candidate
Foam may suit people with symptomatic tributary veins or those who need follow-up treatment after ablation of a main vein. It is generally avoided during pregnancy, in people with a known allergy to the sclerosant, and when there is acute deep vein thrombosis or an infection near the treatment area.
Duplex ultrasound mapping is an important first step. Two people with similar-looking veins can have different patterns of reflux. Treating visible surface veins without addressing an underlying faulty vein may lead to disappointing or short-lived results.
What to expect, step by step
A typical pathway begins with a consultation, medical history and duplex ultrasound. The clinician then marks the veins and performs a series of injections. Ultrasound guidance is used for veins that cannot be clearly seen from the surface. When researching foam sclerotherapy Melbourne, ask whether duplex ultrasound mapping is performed and who interprets the results. Compression is usually applied immediately afterwards, followed by a short walk.
RadiologyInfo notes that a sclerotherapy session commonly takes about 30 to 45 minutes. More than one session may be needed, depending on the number and size of the veins. Your doctor should explain the expected treatment plan and why staged sessions may be appropriate.
Aftercare and recovery
Compression is a common part of aftercare. Cleveland Clinic describes wearing support stockings for three to seven days and avoiding hot baths and saunas for 48 hours. The 2022 European Society for Vascular Surgery guidelines suggest considering compression after foam sclerotherapy or thermal ablation, with the duration tailored to the patient. Instructions can therefore differ between clinics and procedures.
Most people can walk on the day of treatment and return to desk work soon afterwards. Follow the treating clinician's advice about exercise, travel and compression. Contact the clinic promptly if you develop worsening leg pain, swelling in one calf, chest pain, breathlessness, or new visual or neurological symptoms.
Results and limitations
RadiologyInfo reports that sclerotherapy may eliminate 50 to 80 per cent of injected veins per session, which helps explain why staged treatment is common. Fine veins may improve within several weeks, while larger veins can take several months to fade.
A treated vein may remain closed, but recanalisation, where blood flow returns through the vein, can occur. New varicose veins can also develop over time because treatment does not remove the underlying tendency to venous disease. Further review or treatment may therefore be needed.
Risks and side effects, in plain English
Common effects include bruising, tenderness and temporary brown staining along the treated vein. Fine red vessels can also appear near an injection site, a reaction sometimes called matting. Less common but more serious complications include deep vein thrombosis and pulmonary embolism. Temporary visual disturbances and migraine-like headaches have also been reported after foam treatment.
Bring a complete medication list to your consultation. Tell the doctor about allergies, previous blood clots, clotting conditions, migraine with aura and planned long-haul travel so these factors can be considered in the risk assessment.
How foam compares with EVLA, RFA and glue
Evidence generally favours thermal ablation for reflux in the main superficial veins. A 14-year randomised follow-up comparing endovenous laser ablation, surgical ligation with stripping, and foam sclerotherapy for great saphenous vein reflux found poorer long-term outcomes for foam. In contrast, joint US venous guidelines recommend mini-phlebectomy or ultrasound-guided foam sclerotherapy for symptomatic tributary veins. It can also help to compare varicose vein treatments in light of ultrasound findings and a clinician's assessment.
Together, these findings suggest that foam is a practical option for tributaries, smaller veins and follow-up treatment. Using foam alone for main-vein reflux may carry a greater chance of retreatment. The appropriate option still depends on ultrasound findings, symptoms, medical history and a clinician's judgement.
Medicare and cost questions in Victoria
Medicare rebates apply only when the relevant eligibility conditions are met. At the time of writing, MBS item 32500 requires demonstrated reflux of at least 0.5 seconds, excludes treatment performed solely for cosmetic reasons and limits the number of eligible sclerotherapy treatments within a 12-month period. Item descriptions can change, so check the current wording on MBS Online or ask the clinic which items it expects to claim.
Many vein services are delivered outside hospital, and out-of-pocket costs are common. Before booking, request written financial information covering the consultation, ultrasound, procedure, compression garments and follow-up appointments.
How to choose a Melbourne clinic and what to ask
Ask the following questions before agreeing to a treatment plan:
Is the treating doctor registered with AHPRA, and what experience do they have in venous disease?
Is duplex ultrasound mapping performed on site, and who interprets the results?
Does the clinic offer several treatment methods, or is its recommendation limited by available equipment?
What compression is recommended, and how long should it be worn?
When is follow-up scheduled, and is a review scan included?
What happens if a possible complication develops, including how the clinic assesses suspected DVT?
If you're comparing Melbourne providers, information published by clinics such as Vein Doctors can help you understand how foam sclerotherapy is performed. Your suitability, expected costs and Medicare eligibility should still be confirmed during an individual consultation.
