Is there a single best treatment for varicose veins?

No — and a recommendation made before an ultrasound should be treated with caution. Each technique suits particular vein diameters, depths and shapes. The duplex scan maps your anatomy, and the technique is chosen to fit it; for one patient that points to heat-based ablation, for another to adhesive closure or a non-thermal method.

Do I need an operation in the traditional sense?

Usually not. Most varicose veins today are treated through a needle puncture under local anaesthesia, walk-in walk-out. Open surgery — ligation and stripping — still has a place for selected anatomy, but it is the exception rather than the default.

Can everything be done in one visit?

The consultation, the duplex ultrasound and the treatment plan happen in a single visit. Treatment itself is usually scheduled separately, and where it is sensible to combine steps — closing the truncal vein and removing surface branches in one sitting — that is planned deliberately, so most patients need one or two treatment sessions rather than a long series.

Choosing a Varicose Vein Treatment

Stockings, sclerotherapy, heat, glue, MOCA, echotherapy or surgery — how the options compare, and how the scan decides which fits you.

Start with the scan, not the treatment

Every option below treats a different part of the same problem — leaking valves in the superficial veins. Which one fits you is decided by a duplex ultrasound: which vein is leaking, how large it is, how straight it runs and how deep it sits. In my clinic that scan is done during the consultation itself, I read every scan, and the findings — not a standard menu — drive the recommendation. International practice supports this sequence: the European Society for Vascular Surgery's 2022 guidelines recommend duplex ultrasound as the first-line investigation, and endovenous treatment ahead of open surgery when a truncal vein is the source.

The options at a glance

Treatment	Anaesthesia	Entry	Stockings after	Back to routine
Endovenous ablation (RFA/laser)	Tumescent local along the vein	One puncture	Usually yes	Typically within days
VenaSeal	Single local puncture	One puncture	Usually not needed	Typically within days
MOCA	Single local puncture	One puncture	Usually yes, short period	Typically within days
HIFU echotherapy	None, or local for comfort	No puncture	Anatomy-dependent	Same day for most
Sclerotherapy	None — very fine needles	Fine needles	Usually yes	Same day for most
Microphlebectomy	Local	1–2 mm nicks	Usually yes, short period	Days
Ligation & stripping	General or regional	Incisions	Yes	Longer — typically a week or two

These are process facts, not a scoreboard — the right row for you depends on the scan, and the honest comparison of trade-offs happens at consultation.

The conservative rung

Compression stockings, leg elevation and exercise control symptoms and slow progression, but they do not close a leaking vein. They are the right first step when symptoms are mild, when surgery must wait, or when a definitive procedure is not wanted.

Closing the leaking truncal vein

This is the definitive step for most people with true varicose veins:

Endovenous ablation (RFA/laser) — the heat-based workhorse with the longest follow-up data. Requires tumescent anaesthesia along the vein.
VenaSeal — medical adhesive; a single puncture, no tumescent anaesthesia, usually no stockings afterwards.
Mechanochemical ablation (MOCA) — rotating wire plus sclerosant; non-thermal, useful for below-knee segments.
HIFU echotherapy — fully non-invasive, no skin puncture at all; newer, with evidence still accumulating, and anatomy-dependent.

Clearing the visible veins

Microphlebectomy removes bulging surface veins through 1–2 mm nicks, often in the same sitting as ablation.
Sclerotherapy — liquid for spider veins, ultrasound-guided foam for larger residual branches.

Where open surgery still fits

Saphenofemoral ligation and stripping — the traditional operation — is now reserved for selected cases: veins too large, too tortuous or too close to the skin for catheter techniques, or anatomy where previous treatment has changed the options. It remains a sound operation in the right vein; it is simply no longer the default.

Putting it together

Most treatment plans combine a truncal treatment with a finishing treatment, sequenced over one or two visits. If you have been quoted a single technique without a scan, the honest answer is that nobody yet knows whether it is the right one. An ultrasound-based consultation settles the question — and the plan — in one visit.
