Telangiectasia - it is a local or common vascular dilation of small-caliber non-inflammatory origin, accompanied by the development of resistant cosmetic defect.Due to the fact that the morphological characteristics of telangiectasia a spot on the skin of star-shaped, this vascular pathology is often called "spider veins".Telangiectasia exclusively localized in the outer layers of the skin and often have a small size, which favors their removal by laser irradiation or sclerotherapy.
risk for vascular disease of the face up to 45 years of age, and children immediately after birth.According to international statistics, the majority of women with at least one birth in history, suffering telangiectasia.
Experts in the field of vascular surgery allow several etiopathogenetic theories of the origin telangiectasia.Some of them prefer to "hormone theory" according to which the expansion of the lumen of small caliber is the result of hormonal imbalance in
In addition, there are a number of dermatological pathologies profile, which can be the background for the development of telangiectasia, and these include: xeroderma pigmentosum, rosacea, radiation dermatitis.
Various embodiments of cardiovascular disease, are accompanied by small caliber vessels (Raynaud's disease, varicose veins), almost 100% of instigate the formation of telangiectasia.
Note that even completely healthy person not suffering from any vascular or skin disease may be formed telangiectasia due to the negative impact of trigger factors of risk in the form of direct exposure to sunlight that occurs when frequenting tanning, smoking and alcohol abuseat adynamia.
Experts in the field of vascular surgery at Etiopatogenetichesky share telangiectasias on the basis of primary (hereditary), which most often occur among pediatric patients, and secondary (developing on the background of any other disease).
main pathogenetic mechanism of formation of telangiectasia in the projection of the lower limbs is a violation of local blood circulation and increase the gradient of intravascular pressure, similar to varicose disease.The only difference is that when telangiectasia suffer small caliber vessels.
Symptoms and signs of telangiectasia
vascular telangiectasia can be placed on the skin of almost any part of the body, but there are "favorite" of the localization of vascular disease: the face, upper and lower limbs, and neck.
Since telangiectasia of the skin may occur as a result of destruction of small vessels both venous and arterial bed, there are many options of shapes, colors and sizes of skin cells.Telangiectasia, formed by local dilation of capillaries and arterioles, are bright red in color, well-defined star-shaped contours and disappear on palpation, which is a pathognomonic sign when they are identified.Telangiectasia venous type is characterized by the formation of many maroon spots with a bluish tint, towering above the surface of the skin.
telangiectasia most often are local, but in some cases skin lesions observed over a large area and the formation of a huge number of spots of different shapes, sizes and colors.In addition to general
specific manifestations telangiectasia may have some individual characteristics, which depend on the background of a pathology developed vasodilatation.For example, in systemic lupus erythematosus largely observed damage the small capillaries in the projection of nail ridges, combined with hyperpigmentation.Expansion vessels supplying the fingertips, in dermatomyositis is accompanied not only by the formation of telangiectasia, and severe pain in the area.
Essential generalized telangiectasia of the lower extremities different adverse progressive course and is characterized by the formation of small spots in the projection of the feet, which quickly spread to other parts of the body.
Telangiectasia neonates appear forming a so-called "marble skin" having the form of a grid of red, manifested in excessive physical or psycho-emotional activity.
Telangiectasia may have a tree, linear, star or spotting shape.Tree telangiectasia often localized on the skin of the lower limbs, and are located mainly on the face of the linear forms of the disease.
Telangiectasia children ages newborn found in more than 80% of cases and is a transient state compensatory, in most cases do not require medical intervention.The appearance of telangiectasia in these cases due to the presence of physiological balance embrionarnogo rudimentary vessels.In newborn infants, the favorite localization telangiectasia is the occipital region, different areas of the face, especially the lips.In the development of congenital telangiectasia plays an important role in the effects of the baby high estrogen levels mother.If ataxia telangiectasia, which is the immunodeficiency disease, in addition to the destruction of the skin of the child celebrated the defeat of the vascular bed of the internal organs.
There are a number of specific diseases associated with the development of telangiectasias localized on certain areas of the face.So, for scleroderma characterized by the formation of telangiectasia mottled form, which developed numerous amount on the skin of the face and can sometimes be quite large size of individual elements (diameter up to 7 mm).
haemorrhagic teleangietaziya that observed at Osler-Rendu disease, often accompanied by the formation of vascular extensions mucous membranes of the oral cavity, and can also be located in the nostrils.With long-term course of the disease, telangiectasia can be formed not only on the skin, and internal organs.
Hereditary telangiectasia may be accompanied by skin lesions of the face over a large area, but under no circumstances did not observe the formation of spots on the mucous membranes, which distinguishes it from hemorrhagic telangiectasia.
in pediatrics most common ataxia telangiectasia, which affects the skin of the face in the projection of the nasal septum, ears, palate and conjunctiva.When nevoid telangiectasia occurs specific lesion of the neck vessels, localized near the location of the nerve bundle.
Currently, experts in the field of cosmetology and vascular surgery offers a wide range of techniques, allowing to neutralize manifestations telangiectasia.One such method is sclerotherapy for quickly and effectively removing telangiectasia.The main advantage of sclerotherapy is its minimally invasive and easy to use.Manipulation involves injecting sclerosant into the lumen of the vessel, the effect of which is aimed at obliteration of the vessel.Of course, one of the steps is the formation of sclerotic obliteration connective strand, but over time the cord is subjected to self-resorption and does not require medical intervention.The field of application is venous telangiectasia sclerotherapy, while to eliminate capillary telangiectasia type this technique finds its application.
Like any medical procedure, sclerotherapy can be used in various versions, depending on the individual characteristics of the manifestations of telangiectasia.For example, in segmental telangiectasia sclerotherapy varicose veins produced several shows, and after its use in a patient can be observed the formation of a local hyperpigmentation, which is self-leveled within six months.
Mikroskleroterapiyu as a treatment option telangiectasia reticular veins of small caliber, should be combined with pre-cooled wraps to enhance the effect.In most cases, the complete obliteration of the vessel sufficiently applying two or three sessions.
If you select either option sclerotherapy should be aware that this manipulation belongs to the category of cosmetic procedures and eliminates the only symptoms telangiectasia.Over time telangiectasia can form in other parts of the body as the primary cause of their occurrence is not eliminated by sclerotherapy.
In a situation where telangiectasias localized on the face, often used in more modern method of disposal - laser photocoagulation, which involves the introduction of the vessel lumen special catheter equipped with a laser source.When exposed to the laser lumen is formed of a large number of steam bubbles which damage the inner shell of the vessel wall, thereby causing replacement by connective tissue lumen.Telangiectasia small caliber disappear after the first session of laser coagulation, while the larger sizes of "spider veins" require repeat treatments.
basic criteria that guide Estheticians when choosing a method to eliminate telangiectasias is the maximum efficiency and minimum adverse effects on the body.According to the requirements of the most consistent with the selective laser photocoagulation, which has become increasingly used in the treatment of telangiectasia.The basis of the method lies in the absorption of laser skin cells and the conversion of light energy into heat energy, accompanied by the electoral defeat of only the affected vessels, while the healthy surrounding tissues remain intact.Due to such a selective approach minimizes the possibility of the formation of coarse connective intradermal scarring that occur with other methods of treatment.With selective laser coagulation fails in 90% of cases resolve telangiectasia any location, and in generalized form there is a significant reduction in their size.
as preventive measures available to reduce symptoms of congenital telangiectasia, should be considered a modification of the patient's lifestyle, which implies drastic restrictions in the use of alcoholic beverages, smoking, avoiding hypothermia and exposure to direct sunlight.
Telangiectasia - a doctor will help ?In the presence or suspected development of telangiectasia should immediately consult a doctor such as a vascular surgeon and dermatologist.
