Formation of thrombosis and its risk factors

In daily life, we often hear this kind of situation. A good person wakes up in the morning, is half-length numb, and speaks unclearly. When he goes to the hospital for examination, it is a “brain stalk”; one day someone has finished the surgery and recovered very well. Ready to go to the toilet after lunch on the day before discharge, sudden chest pain and shortness of breath, fell in the bathroom, and then unconscious, expert consultation is considered postoperative “pulmonary embolism.” These scenes have a common “murderer” — the blood clot. So do you know what a blood clot is? How was it formed? What factors can form a thrombus? Today we will tell you about the blood clots.

How is the thrombus formed?

A thrombus is a small piece of blood that forms on the surface of the endovascular surface of the cardiovascular system or at the site of repair. In a variable fluid-dependent type, the thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. The blood clot is commonly referred to as a “blood clot”. It plugs the passage of blood vessels in various parts of the body like a …

Types of thrombosis and its harms to people

In recent years, blood clots have become more and more common in our lives, and have even become a chronic disease that seriously threatens people’s health. So what are the types of thrombus? What are the hazards? Let’s take a look together.

Thrombosis classification

  1. White thrombus (pale thrombus). It occurs in areas with rapid blood flow (such as arteries, ventricles) or during periods of rapid blood flow during thrombosis (such as the beginning of a mixed-blood clot, the head of a propagating thrombus). Microscopically, the white thrombus is mainly composed of many platelet-shaped trabeculae that are clustered in a coral-like shape. Many neutrophils adhere to the surface and form a leukocyte layer, which is presumably attracted by the chemotaxis of cellulose disintegration products. The platelet trabeculae form a network of cellulose due to the action of activated coagulation factors, and the mesh contains a small number of red blood cells. The naked eye is grayish white, the surface is rough and corrugated, and the material is hard and closely connected to the blood vessel wall.
  2. Mixed thrombus. The main part of the continuous thrombus of the vein (body) is a layer of red and white streaks, which is a mixed
