  Fact-checking   Autentic   DMCA   Report

The telangiectasias, also known as vascular spiders, are small red capillaries or red colored capillaries that appear on the surface of the skin, are very thin and branched and are more frequent on the piernas and on the face, especially on the nose, buttocks , chest and upper and lower extremities. Telangiectasias are more common among women and can indicate diseases such as: systemic lupus erythematosus, cirrhosis, scleroderma and syphilis.

These vessels can be seen at a glance and form a kind of “spider’s canvas” and, in most cases, they do not produce serious health problems or symptoms, being only an aesthetic discomfort, without embargo, in some women can produce pain the sensation of quemazón in the zone, especially during the menstrual period.

The main difference between the telangiectasias and the varices is their treatment, since it is the same suffering. Telangiectasias have a diameter of 1 to 3 mm and are more superficial, whereas varices have a diameter of 3 mm and affect larger and deeper vessels.



It is also important to note that the telangiectasias cannot develop into a varicose vein because they have reached their maximum distension, but it is possible to present telangiectasias and varices at the same time.

main causes

Although the telangiectasias can be seen at a glance, it is recommended to consult an angiologist to evaluate the circulation of the zone, identify the problem and suggest the best treatment. The doctor must differentiate the telangiectasias from the varices, as they require different treatments.

Some factors that favor the formation of these small vessels in the legs are:

  • Cases of telangiectasia in the family;
  • Remain in the same position for a long time;
  • Overweight or obesity;
  • Take the contraceptive pill, use the vaginal ring or another hormone;
  • advanced age;
  • alcohol consumption;
  • Genetic factors;
  • During the embarrassment, due to the increase in the volume of the window and the decrease in the venous return in the legs.

The telangiectasias are more visible in very pale skins, being more discreet in more tanned skins and dark, mulatto or black skins.



Diagnosis of telangiectasia

The diagnosis of telangiectasias is carried out through clinical observation, however, the angiologist could request other exams with the aim of ruling out related diseases that could be causing this problem. The exams that must be indicated are hematology, blood chemistry and liver function tests, as well as radiography, tomography or magnetic resonance imaging.

How is the treatment performed?

The telangiectasias in the legs must be treated by an angiologist, through the performance of a technique called sclerotherapy, which can be performed with microfoam. This technique is carried out in the medical office, and consists of the use of needles and a medication that is injected into the vessel to interrupt the flow of blood. This dries the vessels, cutting off the blood circulation in them.

The treatment for telangiectasias on the face is normally carried out using a laser.

In addition to this, it is important to complement the treatment with a diet and physical exercises guided by the doctor, as well as the use of compression measures. The doctor may recommend a hormonal control to prevent new vascular spiders from appearing, in addition to oral ascorbic acid intake and local dermabrasion.
