EVLT or endovenous laser therapy is a minimally invasive non surgical way to get rid of varicose veins .In the endovenous laser treatment is a 30-45 min in office procedure with no downtime or scarring. EVLT for elimination of varicose veins is quickly becoming the gold standard treatment for truncal varicose veins. Treatment uses laser energy, which is simply a highly concentrated beam of light. Until a few years ago, the only option for removing bulging leg varicose veins was painful stripping surgery requiring hospitalization, scarring, general anesthesia and significant post-surgery conditions. Nowadays, endovenous ablation techniques have almost put an end to these painful surgeries.
Endovenous laser therapy is the minimally invasive Ultrasound guided procedures, where varicose veins are accessed and ablated from inside the veins by means of a laser energy source.Endovenous Laser Treatment (EVLT) is the system that is currently approved by the FDA for endovenous ablation procedures. The success rate for vein ablation using system ranges from 93-95 percent with minimal side-effects or complications. This success rate is much higher than the 85 percent for the older surgical ligation or stripping method.
EVLT involves actually entering the vein and treating the diseased vein from within. Hence the term “endovenous”. and there are accounts of this technique Using ultrasound technology, the diseased vein is identified and entered using real-time ultrasound guidance. At this point, local anesthesia (also called “tumescent anesthesia”) is injected around the vein using the ultrasound to guide us. This solution of local anesthesia serves two purposes. First, the vein itself as well as the surrounding tissues are anesthetized and become “numb”. Secondly, the fluid around the vein helps to protect the surrounding tissues from any collateral injury from the heat of the laser. This surrounding fluid acts as a “heat sink” to protect these tissues.
Now the small needle is entered in the long saphenous vein near your knee which usually causes the varicose veins Thus we enter the diseased vein with minimal trauma and risk to our patients. At this point a small catheter is inserted into the vein. This catheter is then advanced within the vein to treat the entire length of diseased vein. At this point, we are able to advance the laser fiber inside the catheter. The final position of the laser fiber is determined using the ultrasound once again. A laser light is emitted by the fibre as the fibre is pulled back by through the vein. The veins that are closed are superficial veins that handle less than five percent of body’s blood flow. The particular laser which we use the latest biolitec 1470 laser accomplishes this with much less heat than other lasers and radiofrequency devices. The laser we use, directly affects the collagen within the vein wall causing actual shrinkage of the vein which is visible at the one week follow-up visit.
At this point, a small butterfly bandage is applied to the I.V. site and the patient is able to walk out of our office and resume most activities with essentially no discomfort.
