The EVLA Procedure
EVLA is a minimally invasive procedure where laser energy is delivered to the faulty vein that is normally stripped during surgery, causing it to close. There are many veins in the leg so after treatment the body simply re-routes the blood-flow through other healthy veins.
Once your veins have been checked using an ultrasound scanner you will be asked to lie on a treatment table so that the surgeon can get access to your leg.
The EVLA procedure usually takes about 45 minutes . No general anaesthesia is required, just a local anaesthetic. Your surgeon will insert a thin flexible fibre into the faulty vein. The laser emits thermal energy that will close the vein from the inside. Only minimal discomfort, if any, should be experienced.
