Vasins on the legs (telangiectasia): causes and what to do

Telangiectasia, also known as vascular spiders, are small red or purple capillary 'vessels' that appear on the surface of the skin, very thin and branched, more frequent on the legs and face, especially on the nose, neck, chest and upper and lower extremities, being more evident in fair-skinned people. Telangiectasia is more common in women and can be indicative of some diseases, such as systemic lupus erythematosus, cirrhosis, scleroderma and syphilis, for example.

These vases can be seen with the naked eye and form a kind of 'spider's web' and in most cases these vases do not cause serious he alth problems or symptoms, being thus only an aesthetic discomfort, however in some women they can cause pain or burning in the area, especially during menstruation.

The main difference between spider veins and varicose veins is their size, because they are exactly the same disease. Vessels are between 1 and 3 mm, being more superficial, while varicose veins are larger than 3 mm and affect larger and deeper blood vessels. A varicose vein cannot become a varicose vein because it has already reached its maximum point, but what can happen is that the person has both spider veins and varicose veins at the same time.

Main causes

Although these small vases can be observed with the naked eye by the person himself, it is recommended to consult the angiologist so that he can evaluate the circulation in the region, identify the problem and suggest the best treatment. The doctor must identify the spider vein, differentiating it from varicose veins, because they need different treatments.

Some factors that favor the formation of these spider veins on the legs are:

  • Having affairs in the family;
  • Standing in the same position for a long time, as with hairdressers, teachers and shop assistants;
  • Being overweight;
  • Taking birth control pills or using the vaginal ring or other hormone;
  • Advanced age;
  • Alcohol consumption;
  • Genetic factors;
  • During pregnancy due to increased belly volume and decreased venous return in the legs.

Vessels on the legs especially affect women and are more visible on very fair skin, becoming more disguised when the skin is more tanned and in skin tones of brunettes, mulattos or blacks.

How the treatment is done to dry the pots

The spider veins on the legs can be eliminated by the angiologist, through a technique called sclerotherapy, also known as “foam applications”.This technique can be done in a doctor's office and uses needles and a drug that is injected into the vessel to stop the flow of blood. This dries out these spider veins, eliminating the path of blood circulation. Treatment for telangiectasias on the face is usually done with a laser.

The entire treatment can be complemented by diet and physical exercises guided by the doctor, as well as the use of elastic stockings. The doctor may also recommend hormonal control to prevent the appearance of new spider veins, and the interruption of the contraceptive pill may be recommended, for example, in addition to the use of oral ascorbic acid and local dermabrasion.

How is the diagnosis

The diagnosis of telangiectasia is made through laboratory and imaging tests that are indicated with the aim of ruling out other related diseases.Therefore, the doctor recommends performing a blood test, tests to assess liver function, X-ray, tomography or magnetic resonance imaging.
