Surgery to treat varicose veins:
- Microsurgery: A more modern technique in which only the affected paths are eliminated through minimal incisions. Microsurgery is performed under local anesthesia and does not require hospital stay, recovery is almost immediate.
- Sclerotherapy: An injection technique, it consists of producing irritation of the inner walls of the vein, closing the vein. For example, like a healed cord, the sclerosed vein without blood inside appears virtually invisible. Sclerosis can be achieved in two ways:
- Chemical sclerosis: Liquid chemical substances are introduced that irritate the wall of the vein and makes it sclerose, you can also use foams to increase the contact surface and irritate the endothelium causing a more complete sclerosis.
- Laser or photoesclerosis: A laser is a beam of light of a single color. The cells that have that color absorb the luminous energy, warm-up, and end up being destroyed by this heating. This destruction does not affect the surrounding tissues. Varicose veins heat up the red blood cells and, by transmitting this heat to the endothelium, cause it to sclerose. Various forms of laser application can be differentiated:
- Surface Laser: Applied from the outside, through the skin, and mainly treats varicose veins, spider veins, and small superficial veins.
- Endolaser or internal laser: A thin optical fiber is inserted into the vein, closing the affected vein during its travel. It does not allow its use in excessively tortuous veins and some other cases.
Three-step therapy: With this technique the external laser is combined with chemical sclerosis and allows to apply in big, tortuous veins without producing damages to the skin.
