1470 nm laser to take care of veins



Varicose veins are incredibly prevalent in the usa. One out of a couple over 50 have varicose veins. Venous disease is really a spectrum of ailment that ranges from spider veins to increasing degrees of venous insufficiency. In just one health survey, venous disease was discovered being the 7th most common reason for medical referral in the usa. Usually, the disease has limitations to varicose veins and mild leg edema. However, with progressive degrees of venous insufficiency the condition 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 care system, costing around between 2.5 to 3 billon dollars and between 3 and 4 million lost work days each year. It is essential to diagnose venous insufficiency at the beginning of its course and treat appropriately prior to the patient develops one of these brilliant mentioned complications.

Patients with mild to moderate disease will complain of restless leg syndrome, night cramps, heavy or tired legs following the time or perhaps a burning or aching feeling in the legs. As being the disease progresses, they are going to often times have signs of increasing leg pain, swelling, venous hemorrhage, discoloration, superficial or deep phlebitis or leg ulcers. With progressive insufficiency, patients develop increasing degrees of tissue damage and a lot more symptoms.

Before, all that was open to treat varicose veins was venous crossectomy and stripping. Patients were admitted to the hospital and placed under general anesthesia to offer the varicose veins and vascular disease. Recovery was a few weeks and then there were a lot of complications plus a quite high rate of recurrence within just a couple years. Considering that the late 1990s minimally invasive procedures have been used to close varicose veins limiting patients discomfort, recovery and recurrence compared with vein stripping.

Endovenous laser was FDA approved in January of 2002 for the treating of venous insufficiency from the greater saphenous vein. The original lasers were in the 800 to 980 nm wavelength. These lasers were placed within the vein and emit light inside a wavelength that is certainly absorbed primarily by water and hemoglobin. These lasers heat the blood along with the vein wall. There is certainly debate concerning their means of action yet it is conjectured that they can create micro-bubbles that then through conductive heat result in the vein wall to scar down and close shut. Due to the wavelength of light employed in these lasers, there was a lot of tissue damage away from the vein wall. People tended to get 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 in comparison to the older lasers and more specifically targets collagen in 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 the patients. Also, the 1470 laser demonstrated more wall destruction as well as a more homogenous destruction of your vein wall. For its more specific absorption of water inside the vein wall, the vein wall is heated and scarred shut. This limits the amount of damage beyond the vein. In just one study, one and 3 weeks post-laser, the destruction of tissue is a lot deeper inside the 980 nm laser compared to 1470 laser. However the 1470 laser causes more vein wall destruction. Patients given the 1470 laser have excellent results and basically no post procedure pain or bruising. Treating the complete vein takes below half an hour. Patients need hardly any local anesthetic and possess very little down time afterwards. Many people get back to their normal activities later that day or perhaps the next. The 1470 laser has become offered at Cardiovascular Consultants of South Florida.
