Endovenous Laser Ablation (EVLA), also known as Endovenous Laser Treatment (EVLT), is a minimally invasive procedure used to treat varicose veins. It involves the use of laser energy to heat and close the diseased veins, redirecting blood flow to healthier veins. This procedure has largely replaced traditional vein stripping surgery due to its effectiveness, quicker recovery, and lower complication rates.
