What Are EVLA and EVRF?
Modern treatment of varicose veins has advanced significantly, moving away from traditional open surgery to minimally invasive, image-guided procedures. Two of the most commonly used techniques today are:
- EVLA (Endovenous Laser Ablation)
- EVRF (Endovenous Radiofrequency Ablation)
Both methods are safe, effective, and widely practiced in advanced vascular centres.
How the Procedure Is Performed
Although EVLA and EVRF use different energy sources, the basic procedure is very similar.
Step 1: Inserting the Probe
A thin laser or radiofrequency probe (wire) is gently inserted into the affected vein.
- The probe runs along the entire length of the diseased vein
- Placement is done under imaging guidance for accuracy
Step 2: Connecting to the Machine
- In EVLA, the probe is connected to a laser machine
- In EVRF, the probe is connected to a radiofrequency (RF) generator
Step 3: Closing the Vein
Once activated:
- Heat energy is delivered from inside the vein
- The vein walls collapse and seal shut
- Blood is naturally rerouted to healthy veins
Over time, the closed vein is absorbed by the body.
Why These Treatments Are Effective
Both EVLA and EVRF:
- Treat the root cause of varicose veins (faulty vein valves)
- Are minimally invasive
- Require only local anaesthesia
- Allow patients to walk shortly after the procedure
There are no large cuts or stitches, making recovery fast and comfortable.
EVLA vs EVRF: Is One Better Than the Other?
Both techniques have excellent success rates when:
- Performed by experienced doctors
- Using high-quality equipment
- Proper patient selection is done
The choice between EVLA and EVRF depends on:
- Vein anatomy
- Disease severity
- Doctor’s expertise
