Varicose veins: Causes and treatments

Vascular medical treatment

Although varicose veins in the legs can be cosmetic problem, especially among women as they tend to suffer more from this condition, there is luckily an easy solution. In fact, varicose veins can be treated without surgery or with minimally invasive surgery.

At Nordetia we are going to explain what varicose veins are and how they are treated. 

What are varicose veins?

Varicose veins are veins which have enlarged and twisted, and they may appear to be blue or purple in colour beneath the skin. They are most commonly found in the legs but can also be found in other parts of the body. They are more common among women than men.

Why do they appear?

Varicose veins usually appear because the veins are swollen and have lost their valve function to take blood to the heart , the build-up of blood makes the veins  broader and twisted. There are other cases, although less common, in which varicose veins are the result of a venous thrombosis which has causes the vein’s circulation to be blocked. 

The risk factors related to varicose veins are being a woman, spending too much time on your feet, old age, pregnancy, obesity, or a family history of varicose veins.


How are they treated?

In the case of varicose veins there are different vascular medicine techniques, which is the specialist medicine that prevents, diagnoses, treats, and monitors those patients with this condition. 

The techniques used are the following:


Sclerotherapy is a non-surgical treatment for varicose veins. It consists of injecting a medicine (liquid or microfoam in the varicose veins, modifying their internal layers, to cause a swelling which then results in them closing. One of the benefits of this treatment is that it is 100% effective, even in the case of larger varicose veins. 

Endovascular techniques

Endovascular techniques also allow for varicose veins to be treated without surgery. The techniques also involve injecting a microfoam or fitting a catheter in the varicose vein, removing it as the procedure advances. These techniques are some of the most advanced around today when it comes to treating larger varicose veins. 


Phlebectomy is a microsurgical technique to remove varicose veins, which involves making a few minimal incisions that do not require stitches or leave any scarring. It is essentially a minimally invasive procedure. 

It is also important to bear in mind that a phlebectomy is done with local anaesthetic and does not require a scalpel. The patient does not have to be hospitalized, nor rest for days (only 12 hours), or even take any sick leave, as they can return to their normal routine the following day.

Care and recovery

The recommendations to follow after the varicose vein treatment will depend on the type of treatment undergone. For example, in the case of sclerotherapy or endovascular techniques, the patient will have to walk around for 20 to 30 minutes in the case of the former or 30 to 45 minutes in the case of the latter. In turn, following phlebectomy the patient will need to rest for 12 hours.

On the other hand, following sclerotherapy the patient will have to apply compression but only in some cases (when recommended by a specialist). However, this will always be required, but only for a certain time only, in the cases of phlebectomy and endovascular techniques (unless the treatment is with a VenaSeal glue). 

With any of these treatments, it is recommended that a cream with Vitamin K be applied to help remove any bruising that may appear after treatment.

Finally, rest will only be needed in the case of phlebectomy (12 hours), and with thermal ablation techniques (which are included among the endovascular techniques, in which case the recovery time will be for however long your specialist advises).
