Clarivein is the latest minimally invasive technique used to treat varicose veins. This procedure uses a technique called mechano-chemical ablation to non-surgically eliminate incompetent veins. A skinny wire is painlessly placed inside the vein. The wire rotates at a high speed that damages the intima combined with injection of liquid sclerotherapy to complete venous. The combination is a very efficient and painless way to seal the vein.
