Getting to the clinic
Dr Andrew Choong practises at Mount Elizabeth Novena Specialist Centre, on Irrawaddy Road in the Novena medical cluster. The nearest MRT is Novena station on the North-South Line (NS20), a short walk from the building with largely sheltered routes — convenient for patients with leg swelling or limited mobility who would prefer to avoid a long walk outdoors.
Several bus services run along Thomson Road and the surrounding Novena streets. If you come by taxi or ride-hailing, ask to be dropped at the Mount Elizabeth Novena Specialist Centre / Irrawaddy Road entrance, near the lifts serving the specialist suites. Mount Elizabeth Novena provides a paid visitor carpark for those driving. As the Novena area is busy on weekdays, allow extra time at peak periods, and consider dropping a less mobile patient at the entrance before parking.
What deep vein thrombosis care covers
Dr Choong is a vascular and endovascular surgeon whose practice spans aortic disease, peripheral arterial disease, carotid artery disease, varicose veins, dialysis access and venous thromboembolism. For deep vein thrombosis (DVT) he offers endovascular treatments such as catheter-directed thrombolysis and mechanical thrombectomy in selected patients.
- Deep vein thrombosis, a blood clot usually forming in the deep veins of the leg.
- Endovascular clot treatments such as catheter-directed thrombolysis and mechanical thrombectomy in selected cases.
- Venous thromboembolism more broadly, including its assessment and management.
- Other venous conditions such as varicose veins and chronic venous disease.
- Wider vascular work including aortic, peripheral arterial, carotid and dialysis-access surgery.
DVT matters because a clot can cause leg swelling and pain and, in some cases, travel to the lungs. Many cases are managed with blood-thinning medication, but in selected patients procedures to remove or dissolve the clot may be considered. The right approach depends on the clot, the symptoms and the individual.
What to expect at a consultation
A consultation begins with a detailed history of your symptoms, when they started, and any risk factors such as recent surgery, immobility, travel, previous clots or relevant family history. The surgeon will ask about leg swelling, pain and skin changes.
Examination includes assessing the affected leg for swelling, tenderness and skin changes, and checking the circulation. Ultrasound scanning of the veins is commonly used to confirm a clot and assess its extent, and further imaging may be arranged in selected cases. You will then discuss the findings and options, which may include blood-thinning medication, compression, and in some patients endovascular procedures, with an explanation of the benefits and considerations of each.
Preparing for your appointment
- Photo identification, and any GP or polyclinic referral letter.
- Previous records, scans and reports, including any ultrasound already performed.
- A current medication and supplement list, especially any blood thinners.
- Recent blood results if available.
- A written list of symptoms and questions, including dates relevant to the clot.
- Loose clothing so the legs can be examined easily.
After your consultation and follow-up
You should leave understanding your diagnosis and plan, including how any medication should be taken and for how long. Reports from scans are usually available within a few days. DVT and venous conditions often need review to monitor symptoms, check the response to treatment and decide on the duration of blood thinning, so follow-up is an important part of care. Continuity helps manage the risk of recurrence and any longer-term effects, and you may seek a second opinion at any time.
Seek urgent attention for sudden breathlessness, chest pain or coughing up blood, which can indicate a clot that has travelled to the lungs and is a medical emergency, as well as for sudden, severe leg swelling and pain.
Booking, referrals and fees
As a private specialist, Dr Choong can usually be seen without a referral, though a GP or polyclinic letter may help with continuity and with subsidies if you are later directed to public services. For eligible procedures, MediSave, MediShield Life and Integrated Shield Plans may apply within set limits, while consultations are generally out of pocket. As coverage depends on your plan and the specific procedure, confirm fees and claimable items with the clinic in advance.
Common questions
How is a DVT diagnosed?
An ultrasound scan of the leg veins is the usual test to confirm a clot and assess its extent, alongside examination and history.
Is DVT always treated with surgery?
No. Many cases are managed with blood-thinning medication. Endovascular procedures to remove or dissolve a clot are considered only in selected patients.
Why is DVT potentially serious?
A clot can cause leg swelling and pain and, in some cases, break off and travel to the lungs, which is why prompt assessment and treatment matter.
How long will I need to take blood thinners?
The duration depends on the cause and your individual risk. The surgeon will advise and review this over time.
Can I prevent a DVT from coming back?
Steps such as staying active, keeping well hydrated, moving during long journeys and following the recommended treatment can help reduce risk. Your surgeon will advise on measures suited to your situation.
Are endovascular clot treatments suitable for everyone?
No. Catheter-directed thrombolysis and mechanical thrombectomy are considered only in selected patients, based on the clot, symptoms and overall health, and many cases are managed with medication alone.
