Sclerotherapy is a procedure used to treat varicose veins by injecting a solution directly into the affected veins. The solution irritates the vein walls, causing them to collapse and seal shut. The blood flow is then rerouted to healthier veins. Sclerotherapy is often performed on smaller varicose veins or spider veins and can be done in an outpatient setting with little to no downtime.

This technique is highly effective for treating varicose veins, providing relief from symptoms such as aching, swelling, and heaviness in the legs.
