The EVLA procedure takes about 45 minutes and is performed in a treatment room with you lying on a treatment table.. 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 due to the local anaesthetic that is administered along the length of your vein.
