Endovenous: A Laser Therapy to Diagnose Varicose Vein

Endovenous laser treatment is an effective method to treat varicose vein. This minimally invasive treatment uses ultrasound-guided or radiofrequency technique to burn varicose vein (abnormally enlarged veins) in the legs. As in the normal condition blood circulates from the heart to legs via arteries which contain one-way valves so the blood returns from legs against gravity. In this disease, when veins become varicose, valves don’t work properly and allow blood to flow backward and be enlarged. They are subject to high pressure when standing or walking and become painful.

There are some common uses when endovenous treatment is used. Its procedure is used to alleviate the symptoms occurred by the enlarged nonfunctional veins. The usual symptoms of varicose vein include swelling, aching pain, skin irritation or ulcer, inflammation, aching pain etc.

The endovenous ablation uses radiofrequency or laser energy to close off the faulty vessels and diverts blood flow to nearby healthy veins. During the treatment procedure, a catheter bearing a laser fibre is inserted into the great saphenous vein (GSV) or small saphenous vein (SSV) through a small puncture. Under the ultrasound guidance, the catheter is advanced to the level of the groin or knee crease. The laser is activated whilst the catheter is slowly withdrawn. This method is less painful than vein ligation and stripping surgery. The treatment procedure can be performed by giving local anesthesia or a light sedative. Usually it can be finished in 1 and 2 hours, and recovered within a shorter time.

Studies show that endovenous laser treatment for varicose vein closes vein up to 98% of the time. Other than that, patient can also go through other methods such as sclerotherapy or radiofrequency treatment, even vein surgery is recommended in some cases.
