How does Endovenous Laser Ablation work?
In this procedure the laser energy damages the vein walls. This shrinks the vein and closes the faulty vein off so blood cannot flow through it. The closed vein eventually disappears as the body reabsorbs it over time.
What Happens During the EVLA Procedure
- The first step is that your veins are marked out on your legs by our specialist doctor.
- Then the area is fully anaesthetised to prevent any pain or discomfort during the procedure.
- Next a small catheter is placed into the affected vein and a needle is placed inside the catheter.
- A laser fibre is then passed through the catheter and into the vein and strategically positioned with ultrasound guidance, so that the laser tip is just below the top end of the vein. The laser fibre is connected to our state-of-the-art Endovenous Laser Machine.
- Before the laser machine is turned local anaesthetic is placed at strategic points all along the vein. This ensures complete comfort and a completely painless procedure.
- Then the Endovenous Laser Machine is turned on and this activates the laser fibre. It is then slowly withdrawn by an automatic pull back device, thereby destroying the full length of the vein. As the area is fully anaesthetised no pain is felt.
You will be allowed to go home almost immediately after your procedure. We will apply a bandage to the area where the laser fibre was inserted, and you will need to wear the bandages for the first 48 hours post treatment. You will also need to wear special compression socks for 7 days post treatment to help aid recovery and prevent side effects. Will also recommend walking a minimum of 30 minutes each day for 4 weeks after treatment.
Endovenous laser ablation is an extremely low risk procedure. Patients may experience some bruising and discomfort for a few days to weeks, but it should not impact your daily life.
