Why Do Blood Clots Form?
Dr Andrew Choong explains Virchowâs triad: slow blood flow, a greater tendency to clot and injury to the vessel lining. He relates these three factors to situations such as surgery, immobility and other blood clot risks.
What Is a Blood Clot?
Dr Andrew Choong explains the difference between normal clotting after an injury and a clot that blocks a blood vessel. This introduction covers deep vein thrombosis, pulmonary embolism and clots affecting arterial circulation.
Modern Blood Clot Removal for DVT

Dr Andrew Choong describes an assessment for peripheral arterial disease, from walking symptoms and pulse checks to wounds and blood-flow tests. He explains why treatment should match the symptoms, scan findings and overall health of the patient.
Sepsis, Foot Wounds and Poor Circulation
Dr Andrew Choong explains why infection and poor blood flow can be a dangerous combination in a foot wound. This World Sepsis Day video highlights sepsis warning signs and why diabetes can make the seriousness of a wound harder to recognise.
Can Walking Improve Your Circulation?
Dr Andrew Choong explains how walking can help arterial circulation and the calf muscle pump that returns venous blood to the heart. He also identifies warning signs, including rest pain and non-healing wounds, that should not simply be walked off.
Why Do Foot and Leg Wounds Not Heal?
Dr Andrew Choong explains why a wound may struggle to heal when arterial blood supply or venous drainage is impaired. The video distinguishes reduced incoming blood flow from the raised vein pressure associated with venous reflux.
Leg Pain When Walking: Could It Be Claudication?
Dr Andrew Choong explains three questions about leg pain that starts with walking, improves with rest and returns when walking resumes. This pattern can suggest claudication, a symptom of peripheral arterial disease.
Diabetes, Artery Health and Foot Care
Dr Andrew Choong explains how diabetes can affect artery health and why circulation matters when a foot wound develops. This World Diabetes Day video introduces ankle pressure testing and arterial duplex ultrasound.

What Is Endovascular Surgery?
Dr Andrew Choong explains how endovascular treatment works inside arteries or veins through a small access point. He introduces the roles of balloons, stents, aortic stent grafts and catheter-based blood clot removal.
What Is a Duplex Ultrasound?
Dr Andrew Choong explains how ultrasound images show blood vessel structure while Doppler assesses blood flow. Duplex combines both, helping investigate narrowed arteries, venous reflux and possible blood clots.
Arteries and Veins: What Is the Difference?
Dr Andrew Choong explains how arteries carry blood away from the heart while veins return it. He compares walking pain from narrowed leg arteries with the swelling and end-of-day discomfort associated with venous reflux.
