A personal welcome
Welcome. I Am Dr Andrew Choong
Vascular, endovascular, venous and aortic surgeon in Singapore
I am a senior vascular, endovascular and aortic surgeon with over 20 years of international experience. Trained in the United Kingdom and Australia, I care for patients from Singapore, across Asia and around the world.
My practice covers the full spectrum of vascular disease - from varicose veins, deep vein thrombosis (DVT) and peripheral arterial disease (PAD) to complex aortic aneurysms, dissections, carotid artery disease and dialysis access.
My philosophy is simple: evidence-based, patient-centred and clearly explained. Whether you need reassurance, treatment, or a second opinion for a complex vascular problem, I am here to help.
My Patient Philosophy
“You are at the heart of everything I do”
Navigating vascular conditions can feel overwhelming. My role is to guide you with clarity, compassion and expertise - offering options grounded in evidence, experience and a commitment to outcomes that matter to you.
Five commitments
What that means in practice
One surgeon looking after you from start to finish. You see Dr Choong at your consultation, for your scan review, in theatre and at every follow-up. Please feel free to call; if WhatsApp or email is easier for you, that works just as well.
Fees are discussed openly before any treatment, and you receive a written estimate. Insurance panel arrangements are on the insurance page.
Your surgeon throughout.
Dr Choong looks after you personally from the first conversation to the last follow-up. You won’t be passed to a colleague you haven’t met.
Reach Dr Choong directly.
WhatsApp him on +65 9027 8636, or call the clinic on +65 9376 8688. Unless he is operating, he aims to reply to WhatsApp messages within the hour; messages sent late at night are answered the next morning. Emails are answered the same day.
Seen the same day when it’s urgent.
If your problem is urgent, Dr Choong will see you the same day, including outside clinic hours, usually at the Urgent Care Centre at Mount Elizabeth Novena Hospital, or at another private hospital if that is more practical. Message or call to arrange it.
If symptoms are sudden or severe, such as chest pain, breathlessness, collapse, or a leg that is suddenly cold, pale or numb, call 995 or go straight to the nearest emergency department; do not wait for a reply.
Planning a trip to Singapore.
Send your scans and letters before you travel. Once Dr Choong has everything he needs, he aims to reply within 24 hours with a written provisional view, so you know whether a visit is needed, what it would involve and roughly how long you would stay. Interpreting in Bahasa Indonesia and other languages can be arranged through the hospital.
A second opinion, when you want one.
If you’ve been told you need treatment for an aortic aneurysm or dissection, a blood clot or another vascular condition and would like it reviewed, Dr Choong is glad to help, whether or not you go on to treatment here. Once all your scans and reports are in, he aims to give you a full written opinion within 48 to 72 hours.
My professional background
Experience Behind Your Care
Personal care, supported by more than two decades of clinical practice, research and specialist leadership. Not sure what to look for in a specialist? Read how to choose a vascular surgeon in Singapore.
Clinical Experience
Over 20 Years of Vascular, Endovascular, Venous and Aortic Surgical Practice
I began my surgical career in London in 2003, training in the vascular units at St Mary’s and Charing Cross Hospitals, Imperial College London. I then completed an international fellowship at the Royal Brisbane and Women’s Hospital in Australia, followed by consultant posts at King’s College Hospital, London, and the National University Heart Centre Singapore, where I was also Associate Professor of Surgery. I now operate at private hospitals across Singapore from my clinic at Mount Elizabeth Novena.
This experience spans assessment, open surgery and endovascular treatment - procedures performed inside blood vessels.
For my national service during the pandemic, I received the COVID-19 Resilience Medal from the Prime Minister’s Office of Singapore.
Research and Expertise
A Foundation of Evidence-based Medicine
My research spans vascular, endovascular, venous and aortic surgery. Alongside clinical practice, I have completed doctoral research, written peer-reviewed papers and book chapters, and contributed to international aortic research.
For you, evidence-based care means a clear discussion of the available options, their benefits and risks, and how they relate to your health and priorities.

Conditions & treatments
Find the Care You Need
Start with the problem you are concerned about. Your assessment and any investigations guide the treatment discussion.
Aortic Aneurysm and Dissection
Assessment, surveillance and treatment planning for enlargement or tears in the aorta, including complex disease and second opinions.
Varicose Veins and Venous Disease
Advice for visible veins, aching, swelling and skin changes. Understand the role of ultrasound and the treatment options suited to your veins.
Leg Circulation, Diabetic Foot and Wounds
Assessment for peripheral arterial disease, walking pain and wounds that are slow to heal, with treatment directed at the underlying circulation problem.
DVT and Blood Clots
Understand deep vein thrombosis, pulmonary embolism and the role of medicines or procedures in selected patients. Sudden symptoms need prompt medical assessment.
Carotid Disease and Stroke Prevention
Review of carotid narrowing and individual stroke risk, including when medicines, surgery or stenting may be considered.
Dialysis Access
Planning a fistula or graft, checking an existing access and assessing problems that may affect dialysis.
Vascular Screening and Scans
Our vascular lab offers targeted vascular screening and scans, including abdominal aortic aneurysm screening and assessment of arteries, veins and dialysis access. Learn how vascular ultrasound helps guide your care.
Urgent symptoms: Sudden severe chest or back pain, breathlessness, stroke symptoms or a suddenly cold, painful limb need emergency care. Call 995 in Singapore; overseas, seek local emergency care. Do not wait for a website reply.
Complex aortic disease
Careful Planning for the Aorta
I assess the options for each patient, including surveillance, open repair, endovascular approaches such as EVAR, TEVAR and complex stent-grafts, and hybrid repair combining open surgery with endovascular treatment. The appropriate approach depends on your anatomy, symptoms and individual risk; not every aneurysm needs an operation.
Your next step
Preparing for Your Consultation
Appointments, Records and Payment
Bring relevant reports, scan images and a medication list. The Clinic Team can help arrange your consultation, discuss self-payment questions and check the insurance arrangements that may apply to your policy.
Travel and Second Opinions
If you are travelling for a consultation, send your scans and letters before booking travel: once Dr Choong has everything he needs, he aims to reply within 24 hours with a written provisional view. For a second opinion, he aims to give a full written opinion within 48 to 72 hours of receiving all your scans and reports. An in-person assessment or further tests may still be needed.
