The main principle of laser vein treatment is sending strong bursts of light into the defective vein, which then induces laser energy internally to shrink and seal off the vein walls. Activity of is taken over by the normal veins in the region and they compensate the circulation, thus enabling return to normal and healthy circulation patterns.
Endovenous laser ablation (EVLA), the official name assigned to the laser treatment process, lays focus on thermal destruction of the tissues of the defective vein. Laser energy, via means of a laser of varying wavelengths including 810, 940, 980, 1064 and 1320 nm, is delivered to the defective segment inside the vein through a laser fiber, previously passed through a sheath to the target region. The laser, when fired, it transmits thermal energy to the blood and other cells in the vein, causing irreversible localized venous tissue damage. The laser is fired at regular intervals until the entire circumference of the target vein is destroyed under the effect of the excess thermal energy being radiated into the blood and vein cells. This procedure is highly efficient and post procedure side effects are minimal. Recovery time after the operation ranges for 2 days to 2 weeks depending on the individual undergoing the process.
