EVLT (Endovenous Laser Therapy)
EVLT (Endovenous laser therapy), also known as endovenous laser ablation, is a procedure that uses heat from a laser to reduce varicose veins. Varicose veins are swollen and enlarged ones, most common in the legs. Varicose veins can form when the valves in your veins are damaged, which interferes with blood flow. Too much blood accumulates in the veins over time. Under your skin, the veins may bulge, twist, and protrude. They can also cause leg pain, cramping, or swelling.
A laser is a device that sends a beam of radiation in the form of light. It closes and shrinks the varicose vein, leading to scar tissue formation within the vessel. This closes off the vein, and then the blood flows through other nearby veins.
