Minimally Invasive Varicose Vein Treatment: How Foam Sclerotherapy Works?
Varicose veins are a common yet bothersome condition affecting millions worldwide. These enlarged, twisted veins, typically seen in the legs, are often accompanied by pain, swelling, and discomfort.
While traditional varicose vein surgery was once the only solution, advances in medical technology have led to the development of minimally invasive varicose vein treatments, including foam sclerotherapy, endovenous laser therapy (EVLT), and radiofrequency ablation (RFA).
These treatments offer patients effective results with significantly less downtime than conventional surgery.
This blog will explore foam sclerotherapy, a widely used and highly effective minimally invasive treatment for varicose veins. We will also compare it to EVLT and RFA, highlighting their advantages and differences.
Minimally invasive varicose vein treatments
1- Foam sclerotherapy: How does foam sclerotherapy work?
Foam sclerotherapy is a non-invasive treatment option for varicose veins and smaller spider veins.
It involves injecting a unique foam solution directly into the problematic vein.
This foam irritates the vein lining, causing it to collapse and seal shut. Over time, the body absorbs the vein, and blood flow is rerouted to healthier veins. This treatment is a preferred choice for many individuals due to its simplicity, effectiveness, and minimal recovery time.
Foam sclerotherapy offers a compelling alternative to traditional varicose vein surgery, as it doesn’t require incisions or stitches, eliminating the discomfort and lengthy recovery time.
Advantages of foam sclerotherapy
- Minimally invasive: Foam sclerotherapy is a non-surgical treatment requiring no cuts or stitches.
- Quick recovery time: Since foam sclerotherapy is minimally invasive, patients can generally return to their daily activities almost immediately. There is minimal downtime, unlike traditional surgery, where recovery may take weeks.
- Cost-effective: Foam sclerotherapy can be more affordable than traditional varicose veins surgery. The varicose veins surgery cost for traditional methods can be quite high due to hospital stays and anaesthesia fees, while foam sclerotherapy is typically more economical.
- Effective for small to medium-sized veins: Foam sclerotherapy is most effective for treating smaller varicose and spider veins, significantly improving appearance and discomfort.
While foam sclerotherapy is highly effective for many, some patients may benefit from additional treatments like EVLT or RFA, especially if they have larger, deeper varicose veins.
2- EVLT (Endovenous Laser Therapy)
Endovenous Laser Therapy (EVLT) is another minimally invasive option for treating varicose veins. EVLT utilises laser energy to target and seal off problematic veins. A thin laser fibre is threaded through a small incision, delivering heat to close the vein from the inside.
Like foam sclerotherapy, EVLT has become a popular choice for treating varicose veins due to its minimally invasive nature and relatively short recovery period.
While EVLT is highly effective for many people, radiofrequency ablation (RFA) has gained popularity in recent years due to several key advantages.
3- Radiofrequency Ablation (RFA) for Varicose Veins
RFA (Radiofrequency ablation) is a modern, minimally invasive procedure that utilises radiofrequency energy to close up varicose veins. RFA involves inserting a catheter into the vein, where radiofrequency energy is used to heat and collapse the vein from within.
The body then absorbs the treated vein, and blood flow is redirected to healthier veins. RFA offers several advantages over EVLT. One of the biggest benefits is that RFA tends to cause less pain during and after the procedure.
While EVLT uses laser energy, which can sometimes lead to more discomfort due to the heat, RFA uses radiofrequency, which is generally less painful for patients. RFA also has a higher success rate for larger veins and can provide quicker recovery times.
Advantages of RFA over EVLT
- Less pain and discomfort: One of the primary reasons many patients prefer RFA over EVLT is that it tends to cause less pain and discomfort during and after the procedure. Radiofrequency energy is often less irritating to the tissues surrounding the vein than the heat generated by lasers.
- Faster recovery time: Patients who undergo radiofrequency ablation typically experience a shorter recovery period than those with EVLT. This means less time off work and a quicker return to normal activities, making RFA a convenient option for those with busy lifestyles.
- Higher success rates for larger veins: RFA is particularly effective for treating larger veins, where endovenous laser therapy may be less effective. The radiofrequency energy used in RFA is well-suited to treating these larger veins, ensuring a higher success rate.
- Longer-lasting results: RFA and EVLT have long-term benefits, but studies have shown that RFA may offer slightly better results for large varicose veins, with lower recurrence rates over time.

Other minimally invasive varicose vein treatments
Aside from foam sclerotherapy, EVLT, and RFA, there are other minimally invasive varicose vein treatments available, such as:
- Ambulatory phlebectomy: A procedure where small varicose veins are removed through tiny incisions using specialised tools.
- Ultrasound-guided sclerotherapy: For veins that are deeper and not visible, ultrasound guidance is used to inject the sclerosing agent accurately.
- VenaSeal: VenaSeal utilises a medical adhesive to seal off the affected veins. This unique glue bonds the vein walls together, halting blood flow through the damaged veins and redirecting it to healthier vessels. Over time, the body will naturally absorb the closed veins, causing them to disappear.
As varicose veins aren’t always visible on the surface, an ultrasound will be used to map the veins that need treatment and guide the procedure. The doctor will then use a catheter to apply the medical adhesive to the targeted veins.
Varicose vein removal surgery recovery time
The recovery time for minimally invasive treatments like foam sclerotherapy, RFA, and EVLT is significantly shorter than that for traditional varicose vein surgery.
For most patients, recovery is quick, with the ability to return to work and light activities within a few days. However, avoiding strenuous exercise for a few weeks, post-treatment is recommended.
Minimally invasive varicose vein treatments, such as foam sclerotherapy, EVLT, and RFA, have revolutionised how varicose veins are treated. These options provide patients with effective treatments and minimal recovery time, enabling them to get back to their routine quicker and with fewer risks compared to traditional surgery.
Whether you’re seeking the best treatment for varicose veins or are concerned about the varicose veins surgery cost, these treatments provide excellent alternatives to traditional methods.

FAQ’S
1. What is the least invasive treatment for varicose veins?
The least invasive treatments are sclerotherapy and foam sclerotherapy.
2. What is the best treatment for varicose veins without surgery?
The best non-surgical treatments include sclerotherapy, foam sclerotherapy, and endovenous ablation procedures (like EVLT and RFA). These minimally invasive options treat varicose veins effectively with minimal downtime.
3. How painful is a VenaSeal procedure?
The VenaSeal procedure is generally considered to be low in pain. Since it uses a medical adhesive instead of heat or lasers, patients do not experience the burning or discomfort commonly associated with other varicose vein treatments.
The process requires only a local anaesthetic and one needle prick for access, and most patients report minimal discomfort during the procedure. Additionally, recovery time is quick, and there is typically no need for compression stockings.
4. What is varicose vein surgery cost?
The type of procedure, the clinic or hospital, the severity of the condition, and the patient’s location can all affect the cost of varicose vein surgery.
