Radiofrequency Ablation (RFA)

A Proven, Minimally Invasive Treatment for Varicose Veins

What Is Radiofrequency Ablation (RFA)?

RFA is a non-surgical, ultrasound-guided procedure used to treat Varicose veins caused by venous reflux (backward blood flow).

Instead of removing the vein, RFA:

Targets the root cause (faulty vein valves)

Uses heat generated by radiofrequency energy

Closes the problem vein safely and permanently

The treated vein is gradually absorbed by the body over time.

Who Is RFA Recommended For?

RFA may be recommended if you have:

A Doppler ultrasound evaluation helps determine whether RFA, EVLT, or another option is best for your specific condition.

Medium to large Varicose veins

Confirmed venous reflux on Doppler ultrasound

Leg pain, heaviness, or fatigue

Swelling around ankles or calves

Skin changes caused by vein disease

Symptoms that worsen by evening

How Does RFA Work? (Step-by-Step)

Ultrasound Mapping

The faulty vein is identified and mapped using Doppler ultrasound.

Local Anesthesia

The treatment area is numbed, you remain awake and comfortable.

Catheter Placement

A thin catheter is inserted into the vein through a tiny needle puncture.

Radiofrequency Energy Delivery

Controlled heat is applied along the vein wall, sealing it shut.

Blood Rerouting

Blood automatically flows through healthy veins.

Same-Day Discharge

You can walk immediately and go home the same day.

What Happens to the Closed Vein?

After RFA:

No important blood flow is lost — healthy veins take over naturally.

The sealed vein no longer carries blood

It gradually shrinks and is absorbed by the body

Symptoms improve as circulation normalizes

Patient Guide & Frequently Asked Questions

Is RFA Painful?

Most patients report minimal discomfort.

The procedure is done under local anesthesia

You may feel mild pressure or warmth

Post-procedure soreness is usually mild and temporary

Most people resume normal activities within 24–48 hours.

Recovery After RFA

After the procedure:

You are encouraged to walk immediately

Compression stockings may be advised for a short period

Normal daily activities can resume within 1–2 days

Strenuous exercise may be avoided temporarily

Follow-up ultrasound confirms successful closure

Most patients return to work quickly.

Is RFA Safe?

Yes. RFA is:

Widely used across the world

Backed by strong clinical evidence

Considered a first-line treatment for Varicose veins

When performed by trained specialists, complications are rare.
