Due to its minimal invasiveness and quick recover time, Closure or Venefit (technically referred to as Radiofrequency Ablation) has been adopted as one of the most widely used techniques for treating varicose veins.
Previously, doctors used invasive, violent procedures known as vein stripping, whereby, a diseased vein is literally stripped from the patient’s legs. This procedure was very painful and the patient couldn’t resume normal activity for weeks. Closure, however involves minimal pain, can be completed in 30 to 45 minutes and has you up on your feet immediately.
First, an ultrasound is used to locate and map the diseased vein. Once mapped, the skin is numbed and a small incision is made for the catheter. With the guidance of the ultrasound, the catheter is fed up the length of the vein and then slowly withdrawn. While moving down the vein, the catheter emits a small dose of radiofrequency energy, which heats the walls of the vein. As the vein walls heat up, they slowly collapse and the entire vein becomes “sealed off”. The body then diverts blood flow to other veins and the painful throbbing and swelling disappears.
