Coimbatore: KMCH Hospital has introduced a treatment called “vena seal” for patients suffering with varicose veins. Varicose veins is a condition when the blood vessels taking impure blood from the leg to the heart get enlarged and leads to change in colour of foot. Earlier the only treatment available was a surgery to remove the impure vessels. Vena seal involved inserting a fine tube through a small needle puncture at the knee joint, with ultrasound guidance. The tube is then navigated across the length of the vein and then a medical grade glue is injected along the entire length of the vessel. This glue obliterates the vein permanently, which in turn removes the symptoms caused by varicose veins. tnn
