Varicose veins require serious medical attention just like any other condition. This condition is treated not only for cosmetics but also to eliminate its signs and symptoms. Some of the signs and symptoms of varicose veins are itching in the veins, breeding from the varicose veins, twisted and swollen veins in the legs, hardened veins, inflamed skin, and intensified pain after sitting or standing. Several techniques such as varicose veins surgery, steam ablation, radiofrequency ablation and laser ablation can be used to treat varicose veins. In this article, we will explore explicitly varicose veins treatment by laser ablation.
What causes varicose veins?
Varicose veins are unusually large veins common in the legs. Arteries take blood from the heart to all the body organs and that blood returns to the heart through the veins. Veins have one-way valves which prevent blood from flowing backward when returning to the heart. Blood from the legs has to overcome gravity and hence requires extra energy. If the valves fail and leak, blood flows back in the legs causing varicose veins.
Laser ablation and how it works
Laser ablation is a technique of burning the surface by directing a laser beam into that surface. In varicose veins treatment by laser ablation, a laser beam is used to cauterize and seal off swollen varicose veins. This is how it works;
• The beam is directed to the desired location (regions with varicose veins),
• Laser energy is applied which heats the swollen blood vessels,
• The faulty veins then shrink and the legs gets back to their normal shape.
The main advantage of laser ablation is that it is less-invasive and its effective as it leaves no scars.
How is the procedure carried out?
The procedure should be done by a highly-trained varicose veins specialist to avoid mistakes. The patient organizes with the physician on the treatment basis; either outpatient or admission. This is how the procedure is carried out;
• The leg under treatment is cleaned and sterilized
• The physician may apply anesthetic cream over the swollen veins to avoid discomfort.
• The region where the catheter is to enter into the abnormal vein is numbed and an ultrasound transducer is used to track the path followed by the vein
• The laser fiber is placed in the catheter and its tip is uncovered by pulling the tube back slightly.
• Local anesthetic is injected around the swollen veins by the use of ultrasound guidance. Laser energy is then applied and the catheter is carefully pulled out.
• Pressure is applied to avoid bleeding and the opening left in the skin is bandaged.
That’s basically how the procedure is conducted. It takes a short time for the procedure to be complete.
