Varicose Veins Recurrence After Surgery — Why It Happens & What To Do

"My laser was done two years ago and the veins are coming back. Why?" — this is one of the most distressing questions we hear at our clinic. The honest answer: varicose vein recurrence is real, but with modern technique it should be 5–8% at 5 years, not the 30%+ we used to see with old open surgery.

This evidence-based guide explains the real causes of recurrence after EVLT, RFA, VenaSeal or open surgery — and exactly what can be done if you are facing recurrent varicose veins.

How common is recurrence?

The 4 real causes of recurrence

1. Neovascularisation

The body responds to surgical trauma at the saphenofemoral junction by sprouting brand-new tiny veins (a process called neovascularisation). These new veins eventually dilate and become visible varicose veins. This is the #1 cause of recurrence after old-style open surgery — and the main reason we abandoned stripping in favour of laser/RFA/glue closures.

2. Incomplete original treatment

If the saphenofemoral junction (SFJ) or saphenopopliteal junction (SPJ) was not closed all the way to the deep vein — or if a major perforator vein or accessory vein was left untreated — reflux continues from day one. This shows up as "recurrence" within 6–12 months. Often the cause is operator inexperience or skipping a thorough pre-operative duplex Doppler.

3. New vein disease in different veins

Varicose vein disease is genetically driven. Even after a perfect EVLT of your great saphenous vein, you can develop reflux in a completely different vein 5–10 years later (small saphenous vein, anterior accessory saphenous vein, or perforators). This is "new disease", not true "recurrence" — but it looks the same to the patient.

4. Major lifestyle changes

Pregnancy, significant weight gain, jobs requiring long standing (teachers, surgeons, factory floor workers), and lack of exercise can all unmask new venous reflux that would otherwise have stayed dormant.

How to know if you actually have recurrence

Visible bulging veins are not the only sign of true recurrence. Get a specialist opinion if you have:

• New visible varicose veins on the same leg as before
• Return of leg heaviness or aching
• Re-appearance of ankle swelling
• Skin discolouration or itching over old vein paths
• A new venous ulcer on the ankle

The single most important test is a repeat duplex Doppler ultrasound — done by a vascular specialist, not a general radiologist. It will identify whether the recurrence is from the original vein, a new accessory vein, or a perforator.

Treatment options for recurrent varicose veins

Option 1: Redo EVLT or RFA

If the recurrence is in a clearly identifiable accessory or perforator vein, a fresh laser or RFA closure of that specific vein is the simplest and most effective option. Performed under local anaesthesia, walk-in / walk-out. Cost is similar to first-time treatment.

Option 2: Foam sclerotherapy

For smaller recurrent veins, ultrasound-guided foam sclerotherapy is excellent. A foamed sclerosant is injected directly into the recurrent vein under ultrasound guidance. Two to three sessions are usually required.

Option 3: Phlebectomy (mini-extraction)

For bulging surface varicosities, tiny needle-puncture extractions can be done under local anaesthesia. No stitches needed.

Option 4: VenaSeal glue

For redo cases where avoiding tumescent anaesthesia is preferred (especially for thin patients or anyone with previous complications), VenaSeal glue is an excellent salvage option.

Option 5: AngioJet or pharmaco-mechanical thrombectomy

Reserved for the rare situation of recurrence with extensive thrombosis.

How to prevent recurrence after first treatment

1. Choose a high-volume specialist — recurrence rates triple in the hands of low-volume operators.
2. Insist on pre-operative duplex Doppler done by a vascular specialist, not a generic ultrasound technician. This identifies all refluxing veins before treatment.
3. Make sure ALL refluxing segments are treated in the same sitting — skipping perforators is a common cause of early recurrence.
4. Wear compression stockings for the prescribed 2–4 weeks post-procedure.
5. Annual follow-up Doppler scan for the first 3 years — catches any new reflux while it is still small and easily treatable.
6. Maintain healthy weight, walk 30 minutes daily, avoid prolonged standing.
7. If planning pregnancy, wear graduated compression stockings throughout — pregnancy is the single biggest trigger for new venous reflux.

Conclusion

Modern varicose vein treatments have dramatically reduced recurrence rates from 30%+ (old open surgery) to 5–8% at 5 years (EVLT/RFA/VenaSeal). True recurrences are usually treatable in a single, simple second-time procedure — provided the cause is correctly identified by an experienced specialist with a high-quality Doppler scan.
