Thyroid Artery Embolisation in Singapore
Minimally Invasive Treatment for Selected Benign Thyroid Nodules and Goitres
Thyroid artery embolisation (TAE) is a minimally invasive endovascular treatment that reduces blood flow to selected areas of the thyroid gland. It may be considered for selected patients with benign thyroid nodules, multinodular goitre or enlarged thyroid tissue, particularly when the thyroid enlargement causes symptoms or cosmetic concerns.
During thyroid artery embolisation, a specialist guides a thin catheter through the blood vessels towards the arteries supplying the thyroid. Small embolic particles are then delivered into selected thyroid arteries to reduce blood flow to the targeted thyroid tissue.
Over time, reduced blood flow can cause the treated thyroid tissue or nodule to decrease in volume.
Thyroid artery embolisation is an emerging minimally invasive treatment and is not suitable for every patient. Treatment decisions depend on the thyroid condition, nodule characteristics, vascular anatomy, symptoms and available treatment alternatives.
At the Supreme Vascular and Interventional Clinic, vascular and interventional treatment is led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist.
With expertise spanning the brain and body, the Supreme Vascular and Interventional Clinic provides specialist-led vascular assessment, minimally invasive treatment and continuity of care under one roof.

What Is Thyroid Artery Embolisation?
Thyroid artery embolisation is a catheter-based treatment that reduces blood flow through selected arteries supplying the thyroid gland.
The thyroid receives blood through several arteries. Some thyroid nodules and enlarged thyroid glands have a substantial blood supply.
During TAE, a specialist uses detailed vascular imaging to identify the arteries supplying the targeted thyroid tissue.
Small embolic particles are then delivered through the catheter into selected thyroid arteries.
The particles reduce blood flow to the targeted tissue. Over time, this may cause the treated thyroid tissue or nodule to shrink.
Thyroid artery embolisation does not involve surgically removing the thyroid gland.
What Conditions May Be Treated With Thyroid Artery Embolisation?
Selected Benign Thyroid Nodules and Goitres
Thyroid artery embolisation may be considered for selected patients with benign thyroid disease, particularly when enlarged thyroid tissue causes symptoms or cosmetic concerns.
Potential applications include:
- Large benign thyroid nodules
- Symptomatic thyroid nodules
- Multinodular goitre
- Large benign goitres
- Goitres with substernal or retrosternal extension
- Selected functioning or hyperfunctioning thyroid nodules
Recent evidence and expert consensus suggest that TAE may be particularly relevant for selected patients with large-volume benign thyroid disease, including disease with substernal extension. Treatment decisions require specialist assessment and consideration of established alternatives.
How Does Thyroid Artery Embolisation Work?
Reducing Blood Flow to Targeted Thyroid Tissue
Before treatment, detailed thyroid and vascular imaging is performed to assess the thyroid, identify the target tissue and map its blood supply.
During the procedure, a small catheter is introduced into a blood vessel, usually through the wrist or groin. The catheter is carefully guided towards the arteries supplying the thyroid. Detailed imaging is used to identify the relevant thyroid arteries and surrounding blood vessels. Small embolic particles are delivered into selected thyroid arteries. Blood flow to the targeted thyroid tissue is reduced. The catheter is removed after the planned treatment is completed.
The treated thyroid tissue may gradually decrease in volume following embolisation. Follow-up imaging and thyroid function testing may be used to assess the treatment response.
Key Difference: Thyroid artery embolisation reduces blood flow to selected thyroid tissue rather than surgically removing the thyroid or directly heating the nodule.
When Might Thyroid Artery Embolisation Be Considered?
TAE may be considered for selected patients when thyroid enlargement or nodules are causing significant symptoms, cosmetic concerns or other clinical problems.
Your specialist will consider:
- The size of the thyroid nodule or goitre
- Whether the thyroid lesion is benign
- The location of the thyroid tissue
- Whether there is substernal or retrosternal extension
- The blood supply to the thyroid
- Whether the nodule is functioning or hyperfunctioning
- Your thyroid hormone levels
- Your symptoms
- Your overall health
- Previous thyroid treatments
- The potential risks and benefits of TAE
- Whether surgery, thermal ablation, radioactive iodine or another treatment may be more appropriate
Not every thyroid nodule or goitre requires treatment.
A thyroid nodule also needs appropriate diagnostic assessment before a treatment such as TAE is considered.
Thyroid Artery Embolisation vs Other Thyroid Treatments
Understanding Your Treatment Options
Several treatment approaches may be considered for thyroid nodules and goitres depending on the underlying condition.
| Treatment Approach | How It Works |
|---|---|
| Monitoring | Monitors selected thyroid nodules that do not require immediate treatment |
| Medical Management | Uses medication to manage selected thyroid conditions or hormone abnormalities |
| Thyroid Artery Embolisation | Reduces blood flow to selected thyroid tissue using catheter-delivered embolic particles |
| Radiofrequency Ablation (RFA) | Uses controlled heat to destroy targeted thyroid nodule tissue |
| Radioactive Iodine | Uses radioactive iodine to treat selected functioning thyroid tissue |
| Surgery | Removes part or all of the thyroid depending on the condition |
The most appropriate treatment depends on the diagnosis, thyroid function, nodule characteristics, symptoms, size and location, as well as the patient's overall health.
Thyroid artery embolisation is an emerging treatment option and should be considered as part of an individualised treatment discussion rather than as a replacement for established treatments in every patient.
Thyroid Artery Embolisation vs Thyroid RFA
Two Different Minimally Invasive Approaches
Both thyroid artery embolisation and radiofrequency ablation can be used as minimally invasive treatments for selected benign thyroid nodules, but they work differently.
| Thyroid Artery Embolisation | Radiofrequency Ablation |
|---|---|
| Reduces blood flow to selected thyroid tissue | Uses controlled heat to destroy targeted thyroid tissue |
| Uses a catheter placed inside the blood vessels | Uses a specialised needle or probe placed directly into the nodule |
| Targets the arteries supplying the thyroid | Targets the nodule itself |
| May be considered for selected large nodules or goitres | Commonly used for selected symptomatic or cosmetic benign thyroid nodules |
| An emerging treatment approach | More established image-guided treatment for selected benign thyroid nodules |
The two procedures are not interchangeable, and treatment selection depends on the characteristics of the thyroid disease.
Potential Benefits of Thyroid Artery Embolisation
A Minimally Invasive Approach to Selected Thyroid Conditions
For appropriately selected patients, thyroid artery embolisation may provide several potential benefits.
Minimally Invasive Treatment
TAE is performed through the blood vessels using a catheter rather than through open thyroid surgery.
Can Target the Thyroid Blood Supply
Embolisation allows the specialist to target selected arteries supplying the thyroid tissue being treated.
May Reduce Thyroid or Nodule Volume
Reducing blood flow to targeted tissue may cause the treated nodule or enlarged thyroid tissue to decrease in volume over time. Studies have reported reductions in thyroid and nodule volume following TAE.
May Improve Pressure or Cosmetic Symptoms
For selected patients with large benign nodules or goitres, reducing thyroid volume may help improve symptoms related to enlargement or appearance.
May Provide an Alternative to Surgery for Selected Patients
TAE may be considered when surgery is less suitable or when a patient is seeking a minimally invasive approach, depending on the individual circumstances.
It is important to remember: Every thyroid condition is different. The potential benefits of TAE depend on the diagnosis, thyroid anatomy, vascular anatomy, treatment goals and overall health.
What Are the Potential Risks and Limitations?
Understanding the Risks of Thyroid Artery Embolisation
Thyroid artery embolisation is a specialised vascular procedure and carries potential risks.
Potential risks may include:
- Neck pain or discomfort
- Temporary swelling or inflammation
- Changes in thyroid hormone levels
- Temporary or persistent thyroid dysfunction
- Bleeding or bruising at the catheter access site
- Reaction to contrast dye
- Need for additional treatment
The thyroid has a complex blood supply and is located close to important structures in the neck. Careful vascular imaging and selective embolisation are therefore important during treatment.
Your specialist will discuss the potential benefits, risks and alternative treatment options before recommending TAE.
Recovery After Thyroid Artery Embolisation
What Can You Expect After Treatment?
Following thyroid artery embolisation, you will be monitored while your recovery and catheter access site are assessed. Some patients may experience temporary neck discomfort or other symptoms following treatment.
Thyroid artery embolisation (TAE) typically takes 1 to 2 hours to perform. Most patients are discharged home on the same day with a small bandage over the access site. During the first 24 to 48 hours, it is common to experience mild neck soreness or minor swelling in the lower neck. Patients can usually return to light daily activities and desk work within 1 to 3 days.
The thyroid or treated nodule does not necessarily shrink immediately. Changes in volume and symptoms may develop progressively over the following weeks and months.
Follow-up may include:
- Clinical assessment
- Thyroid ultrasound or other imaging
- Thyroid function tests
- Assessment of symptoms
- Monitoring of thyroid hormone levels
- Further treatment if required
Your specialist will provide personalised advice regarding medications, activity and follow-up.

Thyroid Artery Embolisation and Thyroid Function
Monitoring Thyroid Hormone Levels
Because the thyroid produces hormones that regulate metabolism and other important body functions, thyroid function is an important part of treatment planning. Depending on the underlying thyroid condition, TAE may affect thyroid hormone levels.
Patients with functioning or hyperfunctioning thyroid nodules may require particularly careful assessment of thyroid function before and after treatment.
Follow-up blood tests may therefore be recommended to monitor thyroid hormone levels and determine whether additional management is required.
TAE should not be viewed simply as a procedure to reduce thyroid size; the effect on thyroid function is also an important consideration when selecting patients for treatment.

Frequently Asked Questions About Thyroid Artery Embolisation
What is thyroid artery embolisation?
Thyroid artery embolisation (TAE) is a minimally invasive procedure that reduces blood flow to selected areas of the thyroid by delivering small embolic particles through the thyroid arteries.
What is thyroid artery embolisation used for?
TAE may be considered for selected patients with large benign thyroid nodules, multinodular goitres and other forms of benign thyroid enlargement, particularly when symptoms or cosmetic concerns are present.
Does thyroid artery embolisation remove a thyroid nodule?
No. TAE does not surgically remove the nodule. It reduces blood flow to selected thyroid tissue, which may cause the treated tissue to shrink over time.
Can TAE treat a benign thyroid nodule?
Yes. TAE is being used as an emerging minimally invasive treatment for selected benign thyroid nodules, particularly larger symptomatic nodules.
Is thyroid artery embolisation a treatment for thyroid cancer?
TAE is not a standard treatment for thyroid cancer. Its primary emerging applications are in selected benign thyroid disease, although research is continuing into other applications.
Can thyroid artery embolisation treat a goitre?
TAE may be considered for selected large or symptomatic goitres, including some multinodular goitres and goitres with substernal extension.
Is thyroid artery embolisation minimally invasive?
Yes. The procedure is performed using a catheter inserted into a blood vessel, usually through the wrist or groin.
How long does thyroid artery embolisation take?
The procedure duration varies depending on the size and anatomy of the thyroid condition and the complexity of the vascular treatment. TAE typically takes 1 to 2 hours to perform.
Will the thyroid shrink immediately after embolisation?
Reduction in thyroid or nodule volume generally develops progressively over time rather than immediately after the procedure.
Can TAE affect thyroid function?
Yes. Changes in thyroid hormone levels can occur, particularly when treating functioning or hyperfunctioning thyroid tissue. Thyroid function may therefore be monitored before and after treatment.
Is thyroid artery embolisation suitable for everyone?
TAE is an emerging treatment and is only appropriate for selected patients following detailed assessment of the thyroid condition, vascular anatomy, symptoms and alternative treatment options.
