How microsclerotherapy works
As with all sclerotherapy, microsclerotherapy works by injection of a sclerosant solution into a thread vein, killing it.
Thread veins of the legs are very thin walled veins, with walls that are only one or two cells deep. A sclerosant solution is a liquid that contains a substance that kills cells.
When the thread veins of the legs are treated with microsclerotherapy, the optimal strength of sclerosant solution is selected and then this is injected into the tiny thread vein. As the thread vein is so small, blood is pushed out and the sclerosant solution is able to act on the vein wall, killing the cells.
Immediately after the injection has finished, the thread vein should be pressed upon to stop from re-entering it. The best results occur when this pressure is then kept on for 14 days and nights, usually by using graduated pressure stockings. Some people do not like to use this compression but research has shown the results to be less good with the absence of compression hosiery.
After 14 days and nights, the compression stockings can be removed but in many cases the area that was injected can still look red and inflamed. This does not mean that the treatment has been unsuccessful but instead shows that the dead vein is being removed by the body by a process of inflammation.
Over the course of three months, the dead vein is slowly eaten away and 12 weeks after the microsclerotherapy injections, the end result can be seen. If thread veins are still visible, further treatment may be needed.
