Highlights from the Asian Society for Vascular Surgery 2025
Looking back at ASVS 2025 in Singapore, Dr Andrew Choong reflects on open aortic surgery, artificial intelligence and shared learning - and what these discussions mean for informed, individualised vascular care.
Aortic Dissection Warning Signs: Think Aorta! Get a Contrast CT
Aortic dissection may cause sudden severe chest, back or abdominal pain, but it can also mimic other emergencies. Dr Andrew Choong explains warning signs, urgent assessment and the role of contrast CT when dissection is suspected.
World Patient Safety Day: Safer Vascular Care Starts Early
Safer vascular care starts with careful assessment and a clear treatment goal. Dr Andrew Choong explains why symptoms, scans, individual risks and patient preferences should guide decisions about monitoring, medication and surgery.
Keyhole Vascular Treatment | Endovascular Surgery
Endovascular surgery treats blood vessels from the inside through a small access point. Dr Andrew Choong explains balloons, stents, stent-grafts and clot-removal devices, and why suitability depends on the condition and scan findings.
Poor Leg Circulation?
What happens during an assessment for poor leg circulation? Dr Andrew Choong explains the symptom history, foot examination and blood-flow tests that guide individual treatment for peripheral arterial disease in Singapore.
Varicose veins: scan first, treatment second
Similar-looking varicose veins can have different causes beneath the surface. Dr Andrew Choong explains how vascular ultrasound identifies venous reflux and guides a treatment plan that matches your symptoms and scan findings.
What Is Linked to 11 Million Deaths a Year? Sepsis, Foot Wounds and Poor Circulation
A foot wound can become dangerous when infection and poor circulation occur together. Dr Andrew Choong explains sepsis warning signs, why diabetes can mask pain, and when a worsening wound needs urgent assessment in Singapore.
Can Walking Improve Your Circulation???
Walking can help arteries and veins in different ways. Dr Andrew Choong explains structured walking for stable claudication, the calf muscle pump, practical ways to build a routine and warning signs that should never simply be walked off.
DVT Warning: Red, hot, swollen painful leg
New one-sided leg swelling, pain or warmth may be a DVT and needs urgent assessment. Dr Andrew Choong explains possible symptoms, pulmonary embolism warning signs, risk factors and how venous ultrasound helps investigate a suspected blood clot.
What Is a Duplex Ultrasound? Vascular Surgeon Explains
Ultrasound gives the image, Doppler assesses blood flow, and duplex combines both. Dr Andrew Choong explains how vascular ultrasound investigates reflux, narrowed arteries and possible clots, what happens during the scan and how the findings guide care.
EVAR for Aortic Aneurysms: A Pipe Within a Pipe
EVAR uses a stent graft inside the aorta to treat a suitable aneurysm. Dr Andrew Choong explains the pipe-within-a-pipe idea, how suitability is assessed, the role of follow-up scans and why screening decisions should reflect individual risk.
Why Do Some Foot and Leg Wounds Not Heal?
A wound that is slow to heal may reflect poor arterial blood supply, venous reflux or other health factors. Dr Andrew Choong explains why foot and leg wounds need assessment beyond dressings, including warning signs requiring urgent help.
When Is Leg Swelling Not Just Water Retention? 2 of 2
Learn how duplex ultrasound helps assess venous swelling, why improvement with compression does not prove the cause, and when one-sided swelling needs urgent care.
When Is Leg Swelling Not Just Water Retention? 1 of 2
Swollen legs can reflect systemic illness, a local problem or venous reflux. Understanding the cause matters more than calling it water retention.
Why Varicose Veins Feel Worse at the End of the Day
Evening aching and heavy legs can reflect pressure building in veins with leaking valves. Learn how movement, assessment and ultrasound can help clarify the cause.
Arteries vs Veins: What’s the Difference?
Arteries supply blood and veins return it. Learn why walking pain, heaviness and swelling can point to different circulation problems.
Aortic Aneurysm Screening: Why Men Over 55 Should Know This
Aortic aneurysms may cause no symptoms. Learn how age, smoking and family history guide an individual discussion about abdominal ultrasound screening.
Varicose Veins Are Not Just Cosmetic
Varicose veins can reflect faulty valves and venous reflux, not just a change in appearance. Dr Andrew Choong explains aching, swelling and skin changes, how ultrasound helps, and when to seek a vascular assessment in Singapore.
Leg Pain When Walking? It Could Be Claudication | Dr Andrew Choong
Leg pain that repeatedly starts with walking and settles with rest may be claudication. Dr Andrew Choong explains three useful questions, how peripheral arterial disease is assessed and when circulation symptoms need urgent attention.
September is Vascular Disease Awareness Month | Signs & Symptoms
Leg pain when walking, swollen legs or slow-healing wounds can be signs of vascular disease. Dr Andrew Choong introduces the September vascular health series and explains when symptoms need assessment or urgent help.
