Tumour Embolisation in Singapore
Minimally Invasive Treatment to Reduce Blood Supply to Selected Tumours
Tumour embolisation is a minimally invasive procedure that reduces or blocks the blood supply to a selected tumour.
The procedure uses a thin catheter to reach blood vessels supplying the tumour. Small embolic materials are then delivered through the catheter to reduce blood flow to the targeted area.
Depending on the type, location and characteristics of the tumour, embolisation may be used as a treatment on its own or as part of a broader treatment plan.
At the Supreme Vascular and Interventional Clinic, treatment is planned around the individual patient's diagnosis, imaging findings and overall treatment goals.
Care is led by Dr. Manish Taneja, providing specialist image-guided and interventional expertise with a continuum of care under one roof.

What Is Tumour Embolisation?
Tumour embolisation is a minimally invasive treatment that reduces the blood supply to a selected tumour.
Many tumours receive blood through identifiable arteries. During embolisation, a specialist guides a thin catheter through the blood vessels from the groin or wrist area until it reaches the arteries supplying the tumour. Doctors inject or guide these embolic materials through a catheter to stop bleeding, shrink tumors, or close off dangerous blood vessel flaws.
Small particles or other embolic materials can then be delivered through the catheter to reduce or block blood flow to the targeted vessels. The treatment is designed to target the tumour's blood supply while preserving blood flow to surrounding healthy tissues as much as possible.
The exact approach depends on the type, location, size and blood supply of the tumour.

How Does Tumour Embolisation Work?
Targeting the Blood Supply to a Tumour
Your specialist first reviews your diagnosis and relevant imaging. The blood vessels supplying the tumour are identified.
A small catheter is introduced through a blood vessel usually through the groin or wrist area. The catheter is carefully guided towards the vessels supplying the tumour using imaging.
Angiography helps confirm the blood supply and treatment position. Embolic material is delivered into selected tumour-feeding vessels.
Blood flow to the targeted tumour is reduced or blocked.
The catheter is removed and the access site is monitored after treatment.


When Might Tumour Embolisation Be Considered?
Tumour embolisation may be considered for selected tumours where the blood supply can be identified and safely targeted. The procedure may have different roles depending on the individual diagnosis.
For some patients, embolisation may:
- Reduce the blood supply to a tumour
- Help control bleeding associated with a tumour
- Be used before another tumour treatment
- Make another procedure safer or more manageable
- Form part of a broader multidisciplinary treatment plan
Whether embolisation is appropriate depends on the tumour type, location, blood supply, imaging findings and overall treatment objectives.
Your specialist will assess these factors before recommending treatment.
Tumours That May Be Considered for Embolisation
Tumour embolisation can be used in selected situations involving different types of tumours.
Depending on the individual case, embolisation may be considered for:
- Selected liver tumours
- Hypervascular tumours
- Selected kidney tumours
- Selected bone or soft-tissue tumours
- Tumours associated with significant blood supply
- Tumours where reducing blood flow may support another treatment
Not every tumour is suitable for embolisation.
A detailed assessment of the tumour's blood supply and surrounding anatomy is important before treatment.
Tumour Embolisation Before Surgery
Reducing Blood Supply Before Another Treatment
In some circumstances, tumour embolisation may be performed before surgery or another tumour-directed treatment.
Reducing blood flow to a highly vascular tumour may help reduce bleeding during a subsequent procedure. Whether pre-operative embolisation is appropriate depends on the tumour and the planned treatment.
The decision may involve coordination between the interventional specialist and other members of the patient's treating team.
Potential Benefits of Tumour Embolisation
A Targeted, Minimally Invasive Approach
For appropriately selected patients, tumour embolisation may offer several potential benefits.
Minimally Invasive
Treatment is performed through a small catheter rather than open surgery.
Targeted Treatment
Embolic material is delivered into selected vessels supplying the tumour.
Reduces Tumour Blood Supply
The procedure is designed to reduce blood flow to the targeted tumour.
Can Support Other Treatments
Embolisation may sometimes be performed before surgery or another tumour-directed treatment.
Image-Guided Precision
Angiography allows the specialist to identify the tumour's blood supply and guide treatment precisely.
Individualised Treatment
The embolisation approach is tailored to the tumour's location, blood supply and treatment objectives.
Tumour Embolisation vs Tumour Ablation
Understanding the Difference
Tumour embolisation and tumour ablation are different interventional treatments.
| Treatment | How It Works | Access Method | Primary Treatment Approach |
|---|---|---|---|
| Tumour Embolisation | Reduces or blocks blood flow to the tumour | Groin or wrist catheter (Transarterial) | Targets the tumour's blood supply |
| Tumour Ablation | Uses energy to destroy targeted tumour tissue | Directly through the skin (Percutaneous) | Directly destroys tumour tissue |
In some cases, interventional treatments may be combined or incorporated into a broader treatment plan.
The appropriate approach depends on the tumour type, location, size, blood supply and overall treatment objectives.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Tumour embolisation is minimally invasive, but as with any medical procedure, there are potential risks and considerations.
These may include:
- Temporary discomfort
- Bruising or tenderness at the catheter access site
- Nausea or fatigue
- Temporary fever or flu-like symptoms
- Reaction to contrast material
- The possibility of requiring additional treatment
The specific risks depend on the tumour, its blood supply, the embolisation technique and the patient's overall health.
Your specialist will explain the expected benefits, potential risks and available alternatives before treatment.
Recovery After Tumour Embolisation
What Can You Expect After Treatment?
Recovery varies depending on the tumour being treated, the extent of embolisation and the patient's overall health. The active embolization procedure typically takes 1 to 2 hours (sometimes up to 3 hours for complex arterial networks or multiple tumors). Because tumour embolisation is minimally invasive instead of surgical cuts, recovery is relatively fast compared to open surgery.
After treatment, you may be advised to:
- Rest for a period after the procedure
- Monitor the catheter access site
- Follow medication instructions
- Maintain appropriate hydration when advised
- Gradually return to normal activities
- Attend follow-up appointments
- Complete recommended imaging or blood tests
Some patients may experience temporary fatigue, discomfort, nausea or fever following embolisation. Depending on the size and location of the tumor, you may go home the same day or require an overnight hospital stay (1 to 2 days) for observation.
Your specialist will provide personalised recovery instructions based on your treatment.
