Scientists Invented a Method for Treating Varicose Veins: Blood Boiling
A group of Russian scientists has concluded that blood boiling due to laser radiation is the main factor for successful treatment of varicose veins in humans. According to the scientists, further study of this process will help simplify this medical technology and make it more affordable for the public. The results of the scientific work were published in the journal Quantum Electronics.
Blood boiling in the vein under the influence of radiation is the main factor that ensures the therapeutic effect of the laser, scientists believe.
Co-author of the article Artem Kiselev reports that varicose veins have been treated with lasers for about 20 years, but the physical principle of this method was not fully understood. It is generally believed that the therapeutic effect (denaturation or closure of veins) occurs due to damage to the endothelium — the inner cells of the vessel walls.
"Our studies have shown that the endothelium is damaged due to the thermal effect on the blood. Boiling blood creates volumetric hot jets, which cause the vein wall to begin to close."
Currently, most phlebologists work with specialized equipment that treats veins with a laser using a circular optical fiber. If subsequent studies confirm that vein treatment occurs precisely due to blood boiling, simpler and cheaper optical fibers could be used for this procedure. According to the scientist, this research will eventually allow the development of more accessible technologies for laser treatment of varicose veins.
Researchers from the School of Biomedicine of FEFU and the Russian Academy of Sciences (from Moscow, Vladivostok, and Chernogolovka) participated in the work.
