What are the three major factors for high risk of VTE?

VTE generally refers to venous thromboembolism. There is no clinical concept of "three major factors for high risk of venous thromboembolism." In general, high risk of venous thromboembolism may be associated with factors such as immobility, tumors, thrombophilia, surgery, and shock. The specific analysis is as follows:

1. Immobility

If a patient remains bedridden for a prolonged period, blood flow becomes extremely slow and venous return may even be obstructed due to external pressure, leading to blood stasis. This can result in a high risk of venous thromboembolism. It is recommended that patients engage in regular physical activity to reduce the risk of venous thromboembolism.

2. Tumors

Patients with tumors are also at high risk of venous thromboembolism because tumors themselves create a hypercoagulable state. Patients with cancer should receive anticoagulation therapy based on their individual conditions. Medications such as warfarin sodium tablets or rivaroxaban tablets may be used under medical guidance.

3. Thrombophilia

If a patient has thrombophilia, they are more likely to be at high risk for venous thromboembolism. Thrombophilia is usually diagnosed through specialized testing, followed by appropriate treatment.

4. Surgery

After surgery, patients often need prolonged bed rest, which leads to blood pooling and slowed circulation, increasing the risk of venous thromboembolism. This risk is particularly evident after major surgeries, orthopedic surgeries, and cardiac surgeries. Additionally, the use of pain medications post-surgery may further increase the risk of thrombosis.

5. Shock

In patients with shock, poor circulation and sluggish blood flow increase the risk of venous thromboembolism. This risk is especially prominent in cases of septic shock or severe trauma, which are significant risk factors for thrombus formation.

Besides the above, other contributing factors may include long-term bed rest, thrombocytopenia, and certain drug therapies. For patients at high risk of venous thromboembolism, preventive measures should be strengthened, including early mobilization, use of anticoagulant medications, and maintaining a light, healthy diet.
