Our vascular system is a complex network of veins and arteries that branch out like tree roots to carry blood between the body’s extremities and the heart. Particularly in the legs, blood has to flow against gravity to return to the heart, where it can be oxygenated and recirculated throughout the body. To keep blood flowing in one direction, veins have tiny valves that open and close to prevent blood from back flowing. Venous insufficiency, or vein disease, can develop when these valves become weakened or damaged, causing blood to flow backward toward the feet. This backward flow of blood can lead to a condition known as varicose veins.

Non-thermal sclerosant vein closure is considered one of the least invasive forms of varicose vein treatment and tends to be the chosen method of treatment when larger veins are involved. A vein specialist injects a foam solution into part of the diseased vein, causing it to collapse in on itself with no serious side effects. Because non-thermal sclerosant vein closures use a chemical rather than heat to seal the affected vein, the procedure involves fewer injections along the length of the treated vein. As such, patients usually experience fewer side effects, reduce the risk of damage to surrounding nerves or structures, and recover faster than other forms of treatment.
