What is EndoVenous Laser Ablation (EVLA/EVLT)?
EVLA stands for Endovenous Laser Ablation. It is often called EVLT, or Endovenous Laser Therapy. It is a method of treating varicose veins using laser under local anaesthetic – and has many advantages over the old and out of date stripping method of surgery.
‘Endovenous’ means ‘inside the veins’ – or ‘from inside the vein’ in this case. ‘Laser’ is a sort of energy transmission by light – it actually stands for ‘Light Amplification by the Stimulated Emission of Radiation’. ‘Ablation’ is a term meaning to destroy. Therefore EVLA means that laser is used to destroy the veins from the inside.
This minimally invasive procedure has become a first-line treatment for varicose veins and venous insufficiency, offering a safer, more effective alternative to traditional surgical methods.
How Does It Work?
EVLA is performed under local anaesthetic as a ‘Walk-in, walk-out’ technique. To perform EVLA, the surgeon needs a map of the veins to show which ones are the problem. This map is made using Duplex Ultrasound.
The EVLT procedure begins with an interventional radiologist inserting a catheter into the varicose vein. Using ultrasound to see inside the patient, the doctor guides the catheter through the vein. A laser at the end of the catheter heats the walls of the vein, which closes it. This causes blood to stop flowing through the vein.
During the 45-minutes procedure, a laser catheter is inserted into the defective vein. This is usually performed under local anesthesia using ultrasound guidance. The 1470 laser heats the lining within the vein, damaging it and causing it to shrink, and seal shut.
The 1470nm diode laser energy is preferentially absorbed in the intracellular water of the vein wall and in the water content of blood. The irreversible photo-thermal process induced by the 1470 laser energy results in a complete occlusion of the treated vein.
Why Use EVLA?
Varicose veins are often thought to be the lumpy veins that people see on their legs. Although these veins can be seen in some people with vein problems, these visible varicose veins are not the real problem. They are just a sign of the underlying major problem – venous reflux or ‘vein pump failure’.
Unfortunately, when the valves stop working in these main veins, the valves cannot be fixed. Therefore, to stop the blood from flowing the wrong way down the veins and causing damage, we need to close the veins completely.
EVLT/EVLA is a new way to treat varicose veins EVLT without surgery. Instead of ligating and removing abnormal veins, it treats varicose veins EVLT using 1470nm laser energy to deliver targeted heat directly into the vein, causing it to collapse and eventually be reabsorbed by the body.
Advantages include: In-office procedure performed in less than an hour; No hospital stay; Requires just 1 small incision; Instant relief from symptoms; Quick recovery with minimal post-procedural pain; Can resume normal activities immediately.
What is the Difference Between EVLA and EVLT?
The terms EVLA (Endovenous Laser Ablation) and EVLT (Endovenous Laser Treatment) both refer to laser procedures used to treat varicose veins, but the difference lies primarily in the terminology rather than the procedure itself. Here’s how they differ:
1. Terminology Difference:
EVLA (Endovenous Laser Ablation):
“Ablation” refers to the destruction or closure of the vein. This is the process where laser energy is used to heat and seal the vein shut, causing it to collapse and close.
EVLA emphasizes the ablative nature of the treatment, focusing on the process of destroying the vein from within.
EVLT (Endovenous Laser Treatment):
“Treatment” is a more general term, covering the entire procedure of using a laser to treat varicose veins. It can refer to any laser-based therapy used to address the vein issues, including the ablation technique.
EVLT may be used more broadly in some contexts to describe the process of treating varicose veins with laser energy.
2. In Practice:
In most medical contexts, EVLA and EVLT refer to the same laser therapy used to treat varicose veins.
Both procedures involve inserting a laser fiber into the vein through a catheter, then applying laser energy to heat and close the vein, causing it to seal and be reabsorbed by the body.
The outcomes and procedure for both terms are largely the same: successful closure of the affected vein, rerouting blood flow to healthier veins.
3. Clinical Use:
EVLA is commonly used when referring to the ablative action, particularly in scientific or medical literature
EVLT may be used in broader or more marketing-oriented contexts when talking about the overall treatment process.
FAQ
Q: Is general anesthesia required?
There is no need for a General Anaesthetic – in fact using General Anaesthetic to perform Endovenous Laser Ablation adds risk and extra cost.
Q: What types of veins can be treated?
The veins suitable for treatment include Great Saphenous Vein (GSV), Small Saphenous Vein (SSV), and Anterior Accessory Saphenous Veins (AASV).
Q: Does this treat surface bulging?
EVLA does NOT treat bulging surface varicosities directly — these are addressed after main trunk treatment through additional procedures like phlebectomy or sclerotherapy.
Q: How long does recovery take?
Quick recovery with minimal post-procedural pain; Can resume normal activities immediately.
