Visible veins on hands the disease or cosmetic defect?

It is believed that wrists always reflect the age of a person is much more objective than the skin on the face. Often this problem bothers women, used to monitor their appearance. However, experts familiar with the structure of the venous system, swollen veins on the hands a lot more "talk" about physical activity, living conditions, transferred, and existing chronic diseases.

The veins in hands — the most convenient and affordable choice for medical procedures (blood sampling for research, administering medicines). In emergency cases, the status and availability of veins depends on the possibility of rendering assistance. After the tourniquet on the shoulder of the blood in the lower parts (hands, forearm) overfills venous vessels and causes them to protrude above the surface of the skin. This point is used for insertion of the needle. Then relax the harness, and the drug is injected into the blood.

The structural features of the veins on the hands

In comparison with the veins of the lower limbs veins of the hand have their similarities and peculiarities. General properties:

  • location at two depth levels (surface and deep system);
  • the presence of a valve apparatus, which help to hold the blood flow;
  • the existence of anastomoses between the deep and superficial blood vessels;
  • the influence of innervation on the diameter of the vessel, General or local loss of a liaison with nerve fibers contributes to the loss of tone.

The differences:

  • wall veins on the hands is thinner, contains fewer muscle tissue and collagen, therefore, quickly loses its elasticity;
  • the length of the arms shorter than legs, so the distance from the heart to the peripheral point on the fingers of the hand less significant, so the suction action of the right atrium, superior Vena cava, the diaphragm, which more helps in pumping the blood towards the heart;
  • a smaller number of valves on the inner wall (only 20 instead of 25 feet), it reduces the role of their participation in the support of blood flow against the hydrostatic pressure, if the arms are in a lowered position;
  • wrists are not surrounded by the same powerful muscles in the lower extremities, contributing to pushing the blood up, therefore harder to overcome any obstacles by external pressure or internal structure.

Given the mechanisms do not all work the same.

What causes the pathology?

Common diseases that contribute to atony and distension of the veins on the stagnant hand, can be:

  • symptoms of heart failure, particularly right ventricular type, the falling force of suction of the right heart, superior Vena cava;
  • focal changes in the brain in stroke, ischemic attacks,causing the violation of innervation of the vein walls;
  • disease cervical-thoracic spine, from which motor and sensory nerve fibers to the upper extremities.

Expansion of the venous network occurs when hormonal changes caused by pregnancy, early menopause. Influence levels of estrogen and progesterone.

Correlation of mental and emotional stress, stress with swelling of the veins.

Varicose veins of the upper extremity occurs less frequently than legs. Causes combine genetic predisposition with acquired throughout life (obesity, reduced physical activity). Varicose veins progresses and captures the swollen veins on the hands, on the forearms.

In the presence of varicose veins of the patient concerned:

  • pain and heaviness in the arms;
  • numbness of the fingers;
  • you have to sleep at night with curled up hands.

Chronic foci of infection (carious teeth, sinusitis, women's diseases) contribute to the accession of inflammation of the walls of the veins (thrombophlebitis). In this case appear:

  • local disease of the seal;
  • redness of the skin;
  • local edema and swelling of the skin;
  • body temperature rises.

Inside the veins, the formation of a blood clot.

A complication of thromboembolism in the superior Vena cava is particularly life-threatening for people with heart disease, if the embolus can go into the left chamber through the open hole between the Atria or ventricles.

Thrombosis frequently complicates the course of childbirth, infectious diseases, limb injury, impaired cerebral circulation.

Species — migratory thrombophlebitis is more common for men. The affected vein is surrounded by areas of inflamed tissue, the process changes the location, leaving behind brown spots on the skin.
