“Expanded capillaries” are defined in medicine as telangiectasia, or visible skin lesions, caused by dilatation of small superficial venous blood vessels. They represent the initial stage of chronic venous insufficiency, so I can be a prelude to a subsequent varicose disease. Teleangectasis appears as red-purplish or bluish-red arborescence and locate more frequently at the level of the legs. This disease can be treated by the so-called “sclerotherapy”, ie the injection of a sclerosing substance inside the dilated vessel. This substance (polidocanol) irritates the vein and closes it, thus allowing its reabsorption. The product should be introduced through multiple injections, which in addition to treating the obvious capillary vessel, treat the main vessel that is the cause.
The treatment of varicose veins, although small as in the case of teleangectasia, requires several sessions, as it is not possible to use high concentrations of the sclerosing drug in a single session. It is also necessary to know that this venous pathology has evolutionary character, so it is possible to appear in the time of new “dilated veins”, even in the treated area. In order to minimize (but not completely!) This risk is therefore essential to perform prior to the treatment a specialist examination and an echocolor-Doppler venous examination, aimed at excluding a major varicose vein underlying.
