Radiofrequency Ablation (RFA)

What Is Radiofrequency Ablation?

Radiofrequency Ablation (RFA) is a minimally invasive, image-guided procedure used to treat venous insufficiency and problematic veins that are not functioning properly. This technique uses controlled heat delivered through a thin catheter to gently close the affected vein.

At California Vein Institute, RFA is performed with a focus on precision and patient comfort, helping redirect blood flow to healthier veins and improve overall circulation.

How RFA Works

In healthy veins, one-way valves help move blood back toward the heart. When these valves weaken, blood can flow backward and pool in the veins, leading to symptoms such as swelling, heaviness, and visible varicose veins.

During RFA:

A small catheter is inserted into the affected vein using image guidance
Controlled radiofrequency energy is delivered to the vein wall
The vein gently collapses and seals closed
Blood is naturally redirected to nearby healthy veins

This targeted approach allows treatment of the underlying cause of venous insufficiency without the need for traditional surgery.

What Conditions Can RFA Treat?

Radiofrequency ablation is commonly used to treat:

Chronic venous insufficiency (CVI)
Venous reflux
Larger varicose veins associated with underlying vein dysfunction

Your physician will determine whether RFA is appropriate based on your symptoms, imaging results, and overall vein health.

What to Expect During the Procedure

RFA is typically performed in an outpatient setting and is designed to be efficient and well-tolerated.

During treatment:

The area is numbed with local anesthesia
A thin catheter is guided into the affected vein
Radiofrequency energy is applied in a controlled manner
The catheter is removed once the vein has been treated

The procedure usually takes less than an hour, depending on the number of veins being treated.

Recovery and Results

Because RFA is minimally invasive, recovery is generally straightforward. Most patients are able to return to normal daily activities within a short period of time, although specific instructions will be provided based on your care plan.

Following treatment, patients may notice improvement in leg swelling and heaviness, a reduction in vein-related discomfort, and a gradual improvement in the appearance of visible veins. These results develop over time as circulation improves and treated veins are absorbed by the body.

Benefits of Radiofrequency Ablation

RFA offers several advantages compared to more traditional surgical approaches:

Minimally invasive, image-guided treatment
Performed in an outpatient setting
Targeted treatment of affected veins
Reduced downtime for many patients
Designed to improve circulation and relieve symptoms

Is RFA Right for You?

Radiofrequency ablation may be recommended if you are experiencing:

Persistent leg swelling or heaviness
Symptoms related to venous insufficiency
Visible varicose veins linked to underlying vein dysfunction

A consultation and diagnostic imaging can help determine whether RFA is an appropriate option for your condition.
