WHAT ARE VARICOSE VEINS AND WHY ARE THEY FORMED

Varicose veins are veins that have dilated. They are veins that have withstood a pressure greater than normal for a while and are progressively transformed: their diameter increases, they stretch out and become tortuous.

These changes cause the blood that travels through these veins to progressively decreases its speed in its course towards the heart, and, on many occasions, the blood’s direction is reversed. In the lower limbs, during the standing position is when the veins support the greatest pressure, and that is why varicose veins are much more frequent in these areas than in the rest of the body.

There is also a genetic component, inherent to each patient, that determines the elasticity of the vein wall thus making certain people more prone than others to suffer these

In Clínica Premium we have the most advanced techniques required for the treatment of varicose veins. We also count on a general surgery department with specialists in cutting-edge techniques needed to eliminate varicose veins, thus offering great short-term and long-term results.

What are varicose veins and why do they form?

Varicose veins are veins that have been dilated, they are veins that have withstood a pressure greater than normal for a while and are progressively transformed: they increase in diameter, elongate and become tortuous. These changes cause the blood that travels through these veins to progressively slow down on its way to the heart, and in many cases, the direction of the heart is reversed. In the lower limbs, the standing position is where the veins bear the greatest pressure and, that is why, varicose veins are much more frequent in these areas than in the rest of the body.

There is also a genetic component, inherent in each patient, which determines the elasticity of the vein wall and which makes certain people more prone than others to present this problem.

What type of varicose veins exist and how are they treated?

Varicose veins can be classified according to their size and their treatment must be specific to each individual case.

The smallest so-called telangiectasias or varicose veins are spider veins that affect 30% of the population and usually have no symptoms. This type of varicose veins are best treated with the external vascular laser, which emits a high energy beam captured by the haemoglobin of varix, closing the diseased vessel

Medium-sized varicose veins are called reticular. These are varicose veins of approximately 2-4mms, located below the skin meaning they are often not visible to the naked eye and should be searched with a special light. The best treatment for this type of varicose veins is sclerosis with foam, an injection into varix with a substance that closes it and dries it to disappear later on.

Varicose veins which are larger than 8 mm are generally symptomatic varicose veins (heaviness, pain, swelling, changes in skin colour, etc.), meaning they are visible to the naked eye as thick cords under the skin. These varicose veins are usually related to valvular problems of the veins and are best treated with surgery, since it allows removing the varicose veins already formed and closing the defective valves, thereby solving the problem from the root and preventing the reappearance of new varicose veins over time. The best type of surgery for these cases is radiofrequency surgery or endoluminal laser, which goes inside the diseased varicose vein, closing it from inside with minimal incisions and discomfort for the patient.

Do you have to treat varicose veins even if they do not bother you?

Definitely yes. If an already formed varicose vein is allowed to evolve, it will grow exponentially. Due to the high pressure maintained by the varicose veins, its branches will expand and become new varicose veins, complicating the treatment by prolonging its duration and increasing the surface to be treated.

What happens if they are left untreated?

If the venous failure is sufficiently maintained over time and the varicose veins are ones with a valvular failure, the sustained and increasing dilatation of the diseased veins will affect valves that originally had no problems. Signs of venous insufficiency may appear such as oedema (swelling) in areas of decline and changes in skin colour, which becomes ochre due to the deposition of haemoglobin, secondary to the tearing of the small veins. The most severe cases arise venous ulcers; these are open wounds on the skin, generally above the ankle caused by a lack of oxygenation in the skin due to the very high venous pressure sustained in the area. However, even these serious cases can be solved by closing the valves that do not work through a surgical procedure, therefore, solving the problem from the origin and in a definitive manner.

If they close my veins with the treatment, where does the blood go?

This is a frequent question that arises when you do not fully understand the disease. What the treatment closes are not the veins, they are the varicose veins that are already sick and that are not doing their work, the blood they carry does not have the direction it should have, towards the heart, but instead, it has reversed the flow causing it to now go towards the feet. Therefore we close the veins that not only do not work well but in many cases, they overload (and in time they can spoil) veins that are doing their job.

What can I do to prevent having varicose veins?
  • Exercise regularly.
  • Lose excess weight
  • Avoid being a long time standing or sitting without taking a few steps.
  • Avoid high-temperature environments
  • Elevate the legs at noon (above the level of the heart) for half an hour.
  • Use of elastic compression stockings.
  • Showers with alternating hot-cold water
