Varicose Vein Treatment Options: What Each One Does and How They Fit Together
Modern vein treatment is rarely a single procedure. It is a plan built from a scan, usually combining one method to close the source and another to clear the visible veins.
Short answer: varicose veins are treated by closing the refluxing vein that feeds them and, where needed, removing or shrinking the visible surface veins. The source is usually closed from the inside with heat (radiofrequency or laser ablation), medical glue or ultrasound-guided foam; the surface veins are cleared with microphlebectomy or foam. Traditional stripping surgery is reserved for veins unsuitable for keyhole methods. Compression stockings relieve symptoms but do not change the reflux. The combination is decided on a duplex ultrasound.
What is the principle behind all vein treatment?
Varicose veins are the downstream result of a leaking valve higher up, usually in the great or small saphenous vein. Treating only the visible veins without closing the source gives a short-lived result, because the pressure simply finds the next tributary. Every modern plan therefore has two parts: close the source, then deal with the branches. The scan identifies the source; the surgeon chooses the tools.
What are the options?
| Option | What it does | Typical role | Anaesthetic and recovery |
|---|---|---|---|
| Compression stockings | Squeeze the leg to reduce pooling and symptoms | Symptom relief, pregnancy, while awaiting treatment, after procedures | None; worn daily |
| Radiofrequency ablation (RFA) | Catheter heats and seals the refluxing trunk | Closing a straight saphenous vein | Local anaesthetic along the vein; desk work in 1 to 3 days |
| Endovenous laser ablation (EVLA) | Laser fibre heats and seals the trunk | As for RFA | As for RFA |
| Medical glue (VenaSeal) | Adhesive seals the trunk without heat | Closing a trunk where heat or anaesthetic injections are a concern | Single local injection; usually no stockings; same or next day |
| Ultrasound-guided foam sclerotherapy | Foamed chemical irritates the vein lining so it closes | Tributaries, recurrent veins, tortuous veins, bleeding veins; sometimes small trunks | Injections only; may need repeat sessions |
| Microphlebectomy | Removes surface veins through 2 mm punctures | Clearing visible bulging veins, usually with trunk closure | Local anaesthetic; bruising for 1 to 2 weeks |
| Surgery (ligation and stripping) | Ties and removes the trunk through small incisions | Veins unsuitable for keyhole methods; some recurrent cases | Usually general or spinal anaesthetic; longer recovery |

What do the guidelines recommend?
The European Society for Vascular Surgery 2022 guideline and NICE CG168 both recommend endovenous thermal ablation as the first-line treatment for a refluxing great or small saphenous vein, with foam sclerotherapy or surgery when thermal ablation is unsuitable. The ESVS guideline also recognises non-thermal methods such as cyanoacrylate glue as an alternative. Compression stockings are recommended for symptom relief and after procedures, but not as a substitute for treating reflux in people who are suitable for intervention. Treating tributaries at the same time as the trunk, rather than waiting to see whether they settle, is supported by trial evidence showing fewer later procedures.
How are treatments combined?
A typical plan for a leg with a refluxing great saphenous vein and several bulging tributaries is ablation of the trunk, by radiofrequency, laser or glue, with microphlebectomy of the larger tributaries at the same sitting and foam for any smaller ones. A leg with reflux only in a tributary, or with recurrent veins after previous treatment, may need foam alone. A leg with both saphenous trunks refluxing may be treated in one session or two. These decisions are made on the scan and discussed before anything is booked.
What is recovery like?
After keyhole treatment under local anaesthetic you walk out of the day-surgery unit, and walking is encouraged from the first day. Tightness and bruising along the treated vein are normal for one to two weeks. Most people return to desk work within a few days and to full exercise within two weeks, with heavy lifting and long flights deferred for a short period. Stockings are worn for a week or two after heat or foam treatment and often not at all after glue. A check scan at around six weeks confirms the vein has closed. Dr Choong's recovery guide covers the week-by-week detail.
Common questions about varicose vein treatment options
Can I just have the visible veins removed?
If the scan shows no reflux in the saphenous trunks, yes: microphlebectomy or foam alone is appropriate. If a trunk is refluxing, removing the surface veins without closing it tends to lead to new veins within a year or two, so the trunk is usually treated first or at the same time.
Do I need a general anaesthetic?
Not for the keyhole methods. Radiofrequency, laser, glue, foam and microphlebectomy are all done under local anaesthetic, with light sedation available if you prefer. Only traditional stripping surgery routinely needs a general or spinal anaesthetic.
Is one leg treated at a time?
Both legs can often be treated in one session under local anaesthetic if the plan for each is straightforward. Where two trunks and many tributaries are involved, splitting treatment into two sessions keeps each one comfortable and short.
Are the treated veins needed for anything later?
No. The superficial veins that are treated are already failing and are carrying blood the wrong way. The deep veins, which do the real work of returning blood to the heart, are left untouched, and the body reroutes flow through them.
Scan first, then decide
Which combination suits you depends entirely on what is happening beneath the surface. A duplex ultrasound at a first visit maps which veins are faulty, usually on the same day, and you leave with a plan. Read about what a first visit for varicose veins involves, or arrange one:
