World Thrombosis Day 2025
Learn the key signs of deep vein thrombosis and pulmonary embolism on World Thrombosis Day. Early detection saves lives. A quick 60-second guide from a vascular surgeon in Singapore.
World Thrombosis Day — Blood Clots in 60 Seconds
Today is World Thrombosis Day. Here is a quick 60-second explainer on blood clots.
One in four people worldwide die from conditions caused by thrombosis. Blood clots often form silently, most commonly in the legs as a deep vein thrombosis (DVT). When blood flow slows — after surgery, long flights, illness or immobility — a clot can develop.
The danger is when a clot breaks loose and travels to the lungs. This is called a pulmonary embolism (PE). Together, DVT and PE are known as venous thromboembolism (VTE). Around 60% of VTE occurs in hospital, making it the leading preventable cause of hospital-related death.
In clinical practice, especially here in Singapore, vascular surgeons can remove the clot, restore blood flow, and prevent long-term damage using minimally invasive endovascular techniques. But awareness remains the key: recognising symptoms early saves lives.
Know the signs and symptoms of a blood clot:
• Leg swelling
• Pain or tenderness
• Leg discoloration
• Sudden shortness of breath
• Chest pain
• Fainting or feeling light-headed
• A racing heartbeat
If these symptoms appear, seek urgent medical attention.
