What is the cause of capillary dilation in children?

Children are the hope of a family and the future of the motherland. Therefore, every family will give special care and attention to their children. What should parents do if their children have any disease? What causes capillary dilation in children? Is it a serious disease? I think this is a question that all mothers would like to know. Mom, please take a good look at the following explanation. Let's see what happens then.

Telangiectasia in children is a congenital weakness of the capillary walls that prevents them from contracting. Telangiectasia in children usually occurs on the face, neck, back of the head, and scalp at birth or shortly after birth. It can be unilateral and scattered, or bilateral and multiple. In children, capillary dilation initially presents as a light red, dark red, or purple-red lesion of varying sizes on the skin or mucous membranes, ranging from the size of a needle tip to a limb or half of the trunk. The color deepens after crying, with clear boundaries and various shapes, not protruding above the skin, but higher in some areas. After compression, the lesion partially or completely fades and the surface becomes smooth.

In children, telangiectasia is seen with large, irregular, dilated blood vessels with thin walls. Laboratory examination showed anemia, which may be aggravated by repeated bleeding, and coagulation tests were normal. There is pulmonary arteriovenous fistula. Peripheral blood picture shows erythrocytes, normal coagulation time and platelets, and slightly reduced coagulation factor V. Children's telangiectasia gradually develops into telangiectasia on the skin and mucous membranes, and even internal bleeding. Experiments: There are no special abnormalities. Children's telangiectasia has a clear family history and is generally not difficult to diagnose.

Telangiectasia is a persistent dilation of small blood vessels. The dilated blood vessels are mostly small veins or arterioles, which appear as red, thread-like, reticular or star-shaped lesions on the skin and fade when pressed. In normal people, slight dilation of capillaries can be seen on both sides of the nose and cheekbones due to wind and sun exposure, which is within the normal range. However, if a larger area of ​​dilation occurs, it is a manifestation of certain diseases.

If children's capillary dilation is not caused by certain disease factors or long-term use of hormone drugs, it may generally be caused by certain physical factors, such as long-term exposure to wind and sun, living in plateau areas, etc. If the scope is not large or the symptoms are not obvious, you can ignore it. If the symptoms are more serious, dual-wavelength pulsed dye laser (dual-wavelength vascular lesion workstation) can be used for treatment. Using this technology, the child will not feel pain and the effect is reliable.

It seems that living habits also have a great impact on children's capillary dilation. For those children who often live on the prairie, their living environment is different because of their different living habits. Because of the different living environment on the prairie, it is easy to get cold and windy. Therefore, children living on the prairie are prone to capillary dilation. Now you know what causes capillary dilation in children.
