Laser removal of spider veins

Spider nevus is a relatively special phenomenon of capillary dilation. After it appears, it is generally recommended to go to the dermatology department of the hospital for further diagnosis. If spider nevus is diagnosed, the cause must be found out to see whether it is caused by liver disease or by the secretion of adolescent hormones. If it is the latter, you may consider using laser to remove the spider nevus. In addition, physical therapy can also use high-frequency electrocautery, diathermy or microwave therapy for treatment, and the effect is also very good.

1. The principle of laser removal of spider nevus

Because the blood flow direction of spider nevus is from the central point to the surrounding capillary branches, if the central part is compressed, the blood flow will be blocked and the spider nevus will disappear due to ischemia. So, how to remove spider nevi? The principle of laser treatment is to use the hemoglobin in the blood vessels to selectively absorb the energy released by lasers of a specific wavelength, causing damage and complete destruction of the blood vessels, while the surrounding normal skin tissue absorbs very little. Therefore, the ideal effect of eliminating vascular skin lesions without leaving scars can be achieved.

two,   What are spider nevi?

Spider nevi often appear on the face, neck, and chest, but some people may also have spider nevi in ​​other parts of their body. Spider nevus appears as a small round hemangioma with a central diameter of less than 2 mm. It has many capillaries and branches extending outward, and looks like a red spider lying on the skin. If you press the central erythema with a pin head, the surrounding capillaries will fade and return to normal after the pressure is removed.

3. Causes of spider nevus formation

Spider nevi are a sign of disease. Spider nevi are common in acute or chronic hepatitis or cirrhosis. When the liver is diseased, its ability to inactivate estrogen decreases, resulting in a large accumulation of estrogen in the body, causing the dilation of small arteries in the body and the appearance of spider nevi. When liver function deteriorates, the disease increases; when liver function improves, the disease changes from bright red to dark red and then disappears. However, it should be pointed out that the presence of spider nevi does not necessarily lead to cirrhosis. Spider nevi are also a normal physiological phenomenon. Women in adolescence are at the peak stage of growth and development. There is a large amount of estrogen in their bodies, and some spider nevi may appear. This is a normal physiological phenomenon. As we age, estrogen secretion gradually decreases and spider nevi will gradually disappear. This disease can also be seen in pregnant women, usually appearing within the 2nd to 5th month after pregnancy and disappearing after delivery.

4. What to do about spider nevus

Spider nevi themselves are not harmful to the human body, but if spider nevi are found, you should go to the hospital immediately to check your liver function and liver B-ultrasound to rule out malignant tumors and various diseases that cause liver failure. The laser treatment method for spider nevi utilizes the principle of photothermal separation and the selective characteristics of laser, and applies solid pulsed multi-wavelength laser. Since the laser does not forcibly remove the pigment but treats through the skin, it is safe and effective for the treatment of spider nevi and will not leave scars.
