Capillary bleeding

Introduction Capillary hemorrhage refers to small red blood that oozes from the surface of the wound and does not show significant bleeding from the blood vessels. This bleeding can often stop automatically. In daily life, we often see a part of people's facial redness, and the naked eye can see an expansion of capillaries, some of which are red or purple-red spots, spots, lines or stellate damage, this is the capillary Vasodilatation, commonly known as blood red silk. It is a kind of skin damage that occurs on the face or the trunk. Most of them are acquired. Some patients are congenital. Facial telangiectasia is the main cause of beauty. It is mostly caused by women. The clinical manifestation is the filament of the face. , spotted, star-shaped or flaky erythema.

Cause

Climate and environmental factors, long-term living in a relatively harsh living environment, such as the thin air of the plateau, skin hypoxia, resulting in increased erythrocyte number of vascular compensatory expansion, long-lasting vasoconstriction dysfunction caused by permanent telangiectasia. Or long-term contact with wind, cold, hot sailors, chefs, farmers and athletes.

Stimulation of physical factors, such as stimulation of temperature changes, makes the tolerance of capillaries exceed the normal range, causing telangiectasia and rupture. Excessive sun exposure, chronic photodermatitis caused by dry skin, dry skin, etc.

Abuse of cosmetics or long-term "skin monthly treatment", and improper skin loss caused by sequelae, the acidic components of skin rejuvenation products destroy the protective effect of the stratum corneum and the elasticity of capillaries, causing the capillaries to expand or rupture.

Complications of certain local or systemic diseases.

Several common capillary hemorrhagic diseases:

Allergic purpura is a common allergic bleeding disorder. Mainly involving the capillaries. No thrombocytopenia and coagulopathy. In addition to skin purpura, there may be abdominal, joint and kidney involvement.

Telangiectasia

In daily life, we often see some people's facial skin reddish, and the naked eye can see a series of dilated capillaries, some of which are red or purple-red spots, spots, lines or stellate damage, this is the capillary Vasodilatation, commonly known as hemorrhagic retinal hemorrhage, is most common in retinal capillary lesions, mainly due to capillary endometrial damage, increased permeability and blood exudation.

Differential diagnosis

Differential diagnosis of capillary hemorrhage:

1, pulse bleeding: dark red blood, rapid and continuous outflow from the wound. The method of stopping bleeding is roughly the same as that of capillary hemorrhage, but it is necessary to apply a bandage with a little pressure; when it is not too much venous bleeding, the above method can generally achieve the purpose of hemostasis.

2, pulse bleeding: the fierce, bright red color, with the heart beat and sprayed. Aortic bleeding can cause death in a few minutes and needs to be sent to the hospital for emergency treatment.
