The appearance of spider veins, wine stains, dilated veins on the legs and face causes significant discomfort to patients. Vascular pathology, one of the most acute problems in aesthetic medicine, requires a careful attitude and a competent approach on the part of the doctor to its diagnosis and treatment.

Currently, there are many modifications of lasers for the treatment of various vascular skin defects. They differ in the mechanisms of interaction of their radiation with tissues and, for the most part, are designed to solve specific problems.
Intact, healthy blood vessels are approximately 20 microns in diameter, while dilated ones increase to 100 microns (0.1 mm) or more. As a result, telangiectasias appear (popularly called vascular network or rosacea). The term telangiectasia (Latin tel, angio, ectasia) means an enlarged tip of the vessel. This is a congenital or acquired persistent expansion of capillaries, venules and arterioles within the choroid plexus in the subpapillary dermis.
Among the most common reasons for their appearance are the following:
- genetic predisposition;
- endogenous factors: liver disease, lipofibrous degeneration of subcutaneous fat, impaired venous outflow,
- blood clotting disorder;
- pregnancy;
- abuse of sun exposure and solariums;
- steroid use;
- taking hormonal drugs;
- deep skin peels.
Several methods are known to eliminate unwanted vessels:
1. With the help of therapeutic agents.
2. An electrocoagulation method that has been used frequently in the past but can lead to scarring, hyperpigmentation, and depigmentation.
3. Laser coagulation is one of the most effective non-surgical methods for removing unwanted vessels at the moment.
Advantages of laser technology
Today, a new generation Nd:YAG laser is used to solve a number of vascular problems – 1064. This is a laser that emits light in pulses from 10 to 50 milliseconds. Such impulses provide effective vascular coagulation. In addition, the laser is equipped with a skin cooling system, which prevents burns and provides the patient pain-free and comfortable.
Laser coagulation is based on the fact that a light beam penetrates the skin, is absorbed by blood hemoglobin, and is converted into heat, which seals the lumen of the vessel. The patient feels only a slight burning or tingling sensation.
Most often, patients who are concerned about spider veins on the face and legs, rosacea on the face, seek help. Complete or almost complete disappearance of facial telangiectasias is observed in 90% of patients. Dilated vessels of the cheeks are treated without problems. The most difficult to treat telangiectasias localized on the wings of the nose. This requires special care. According to statistics, 15% of patients with alar telangiectasias are resistant to treatment.
Disappearance of dilated vessels can be seen directly during laser treatment. Most pathological vessels (but not all) go away after the first treatment session. The patient's appearance is noticeably improved. Many patients are very satisfied with the result achieved after the first session. However, it may take 2 or 3 treatment sessions to remove all abnormal vessels.
Contraindications for laser photocoagulation are:
- exacerbations of various chronic diseases;
- presence of inflammatory processes in the area of the procedure;
- pregnancy and lactation;
- bronchial asthma;
- rheumatoid arthritis;
- hypertension from stage 3;
- diabetes mellitus;
- vitiligo;
- taking isotretinoins;
- connective tissue diseases;
- susceptibility to keloid scarring.
The advantages of the laser treatment method are that the risk of scarring and injury to surrounding tissues is minimal, and the healing period is significantly reduced. The method can be used in all age groups, as well as in patients with concomitant somatic pathology. The procedure takes little time, is bloodless, does not require anesthesia.
