1470 nm laser to treat Varicose veins are really prevalent in the United States. One from a couple 50 plus have varicose veins. Venous disease is really a spectrum of disease that ranges from spider veins to increasing degrees of venous insufficiency. In just one health survey, venous disease was found to be the 7th most popular cause of medical referral in the United States. Usually, the disease is limited to varicose veins and mild leg edema. However, with progressive levels of venous insufficiency the disease can manifest with increasing signs of leg pain, swelling, venous hemorrhage, venous eczema, lipodermatosclerosis (scarring) and venous ulcerations. Over 1 million Americans have venous stasis ulcers and over 100,000 seem to be totally disabled. Venous stasis ulcers certainly are a huge burden in the US medical system, costing an average of between 2.5 to 3 billon dollars and between 3 and 4 million lost work days each and every year. It is important to diagnose venous insufficiency at the start of its course and treat appropriately prior to the patient develops one of those mentioned complications. Patients with mild to moderate disease will complain of restless leg syndrome, night cramps, heavy or tired legs following the time or a burning or aching feeling inside the legs. Since the disease progresses, they may usually have signs and symptoms of increasing leg pain, swelling, venous hemorrhage, discoloration, superficial or deep phlebitis or leg ulcers. With progressive insufficiency, patients develop increasing levels of tissue damage and much more symptoms. In the past, all of that was offered to treat varicose veins was venous crossectomy and stripping. Patients were admitted for the hospital and placed under general anesthesia to have thevaricose veins and leg swelling. Recovery was few weeks and there were a large number of complications and a extremely high rate of recurrence within just a few years. Since the late 1990s minimally invasive procedures happen to be utilized to close varicose veins limiting patients discomfort, recovery and recurrence in comparison with vein stripping. Endovenous laser was Approved by the fda in January of 2002 for the treating of venous insufficiency of your greater saphenous vein. The initial lasers were from the 800 to 980 nm wavelength. These lasers were placed inside the vein and emit light in a wavelength which is absorbed primarily by water and hemoglobin. These lasers heat the blood as well as the vein wall. There may be debate about their approach to action however it is conjectured which they create micro-bubbles that then through conductive heat result in the vein wall to scar down and close shut. Because of the wavelength of light used in these lasers, there seemed to be a significant amount of tissue damage outside of the vein wall. People tended to have plenty of post procedure pain and bruising. The newer lasers in longer wavelengths 1300 to 1500nms emit light even closer the infrared spectrum which has higher water absorption. The 1470 wavelength laser has 40 times greater absorption in water than the older lasers and more specifically targets collagen within the vein wall. In studies comparing the 980 and 1470 lasers, the 980 laser caused deeper tissue damage which caused more pain and bruising and longer recovery for your patients. Also, the 1470 laser demonstrated more wall destruction plus a more homogenous destruction of the vein wall. Due to

its more specific absorption of water from the vein wall, the vein wall is heated and scarred shut. This limits the volume of damage away from the vein. In one study, one and three weeks post- laser, the destruction of tissue is a lot deeper within the 980 nm laser than the 1470 laser. However the 1470 laser causes more vein wall destruction. Patients given the 1470 laser have excellent results and hardly any post procedure pain or bruising. Treating the whole vein takes below half an hour. Patients need minimal local anesthetic and have almost no down time afterwards. Many people come back to their normal activities later that day or even the next. The 1470 laser has become offered by Cardiovascular Consultants of South Florida.
