世界血栓日 | 什么是血栓？血栓是如何形成的？有哪些危害？一起来看！

Core Viewpoint - The articles highlight the significance of thrombosis, its formation, types, and the importance of prevention and early detection, especially in high-risk populations [1][3][9]. Group 1: Types of Thrombosis - Thrombosis is categorized into three main types: venous thrombosis, arterial thrombosis, and capillary thrombosis [1]. - Venous thrombosis includes deep vein thrombosis (DVT) and pulmonary embolism (PE), while arterial thrombosis encompasses acute coronary syndrome, atrial fibrillation, arterial ischemia, and stroke [1][6]. - DVT accounts for approximately 80% of venous thrombosis cases, making it the most prevalent form [6]. Group 2: Risk Factors and Formation - The formation of thrombosis is influenced by three key factors: damage to blood vessel walls, slow blood flow, and a hypercoagulable state of blood [3][4]. - High-risk groups include individuals over 60 years old, those with hypertension, diabetes, obesity, and those who experience prolonged immobility [6][10]. - Specific conditions such as prolonged sitting, especially in activities like playing mahjong or long flights, significantly increase the risk of DVT [6][10]. Group 3: Symptoms and Detection - Symptoms of DVT include swelling, pain, tenderness, redness, and skin changes in the affected limb [6][8]. - Two simple methods for self-assessment of DVT risk include measuring leg circumference and checking for tenderness in the calf [8]. Group 4: Prevention and Treatment - Preventive measures include regular movement, hydration, and a diet rich in fruits and vegetables while limiting meat and fats [4][11]. - Treatment options for PE include the placement of an interception device to prevent blood clots from reaching the lungs and minimally invasive techniques to dissolve clots [11].
