Vascular Conditions in Singapore

Vascular conditions affect the arteries carrying blood to the body and the veins returning it to the heart. This overview brings together the condition guides from Andrew Choong Vascular Surgery in Singapore, including aortic disease, leg circulation, vein problems, blood clots and dialysis access.

Start with the relevant condition below, then explore its assessment and treatment options. A diagnosis does not automatically mean an operation: monitoring, medicines and changes to everyday habits can be important parts of care.

When should I seek urgent help?

In Singapore, call 995 for sudden severe chest, back or abdominal pain; severe breathlessness or collapse; stroke symptoms such as face drooping, one-sided weakness or speech difficulty; a suddenly cold, painful or weak limb; or heavy uncontrolled bleeding. Do not wait for a routine clinic appointment or an online reply. Seek emergency help even if stroke symptoms disappear.

New one-sided leg swelling or pain needs urgent medical assessment. A diabetic foot ulcer with poor circulation or gangrene needs immediate hospital assessment. New blackened tissue, or a foot wound with fever, rapidly spreading redness or signs of deep infection, also needs urgent hospital assessment. Each condition guide explains its particular warning signs.

Aortic and arterial conditions

Aortic disease and aortic awareness

The aorta is the main artery carrying blood from the heart. The aortic disease guide explains aneurysms, dissections and blockages, including surveillance and the choice between open, endovascular and hybrid repair. The separate aortic awareness guide covers warning signs, family history, screening conversations and follow-up.

For treatment comparisons, explore abdominal EVAR, thoracic TEVAR and the full Treatments Overview, including complex and open aortic repair.

Peripheral arterial disease and leg circulation

Peripheral arterial disease (PAD) can cause pain when walking, pain at rest or wounds that heal poorly. The guide explains assessment, medical care and when restoring blood flow may be considered. Related guides cover leg angioplasty and stenting, bypass surgery and diabetic foot and wound care.

Carotid artery disease

Carotid artery disease affects arteries in the neck that supply the brain. Learn about stroke warning signs, assessment and why not every narrowing requires a procedure. The carotid surgery and stenting guide explains the options considered for selected patients.

Vein conditions and venous ulcers

Varicose veins

Varicose veins may cause aching, heaviness, swelling or skin changes. The guide connects symptoms and duplex ultrasound findings with treatment choices. Dr Choong’s scan first, treatment second video article explains why understanding the pattern of reflux matters.

Chronic venous insufficiency and leg ulcers

Chronic venous insufficiency can lead to persistent swelling, eczema, skin discolouration and venous leg ulcers. This guide explains venous pressure, assessment of arterial circulation, appropriate compression and care for the underlying cause.

Post-thrombotic syndrome

Post-thrombotic syndrome describes persistent problems with venous drainage after a DVT. Read about ongoing heaviness, swelling and skin changes, and why new or suddenly worsening symptoms need assessment.

Deep-vein and lung blood clots

Deep vein thrombosis (DVT)

DVT is a clot in a deep vein, often in the leg or pelvis. The guide covers urgent symptoms, diagnosis, treatment and follow-up. The linked DVT treatment guide explains anticoagulant medicines and the role of procedures in selected circumstances.

Pulmonary embolism (PE)

A pulmonary embolism occurs when a clot blocks an artery in the lungs, often after travelling from a leg-vein DVT. The guide explains emergency assessment, treatment and recovery. New symptoms suggesting PE need prompt emergency assessment, even without leg swelling.

Dialysis access and fistula problems

The dialysis access and fistula guide explains fistulas, grafts and catheters, routine access care and warning signs. Treatment information is organised into planning and creating dialysis access and assessing and treating access problems.

Assessment and next steps in Singapore

How is a vascular condition assessed?

A consultation brings together symptoms, medical history, examination and appropriate investigations. Vascular ultrasound can help answer particular questions about arteries, veins or dialysis access; other conditions need different imaging. Bring previous scan reports, available images and a medication list.

Where can I compare treatments and learn more?

The Treatments Overview connects each condition with relevant options. For explanations in Dr Choong’s own words, browse the vascular health articles and videos. You can also read about Dr Andrew Choong and his vascular and aortic publications and book chapters.
