A non-surgical option for an overactive or enlarged thyroid
TAE is a minimally invasive, image-guided procedure that reduces blood flow to the thyroid. It is done through a tiny puncture at the wrist or groin, with no cut on the neck.
An overactive or enlarged thyroid (goitre) can affect the whole body. Common signs include:
Losing weight even when you eat normally.
A fast, pounding or irregular heartbeat.
Shaky hands and feeling too warm.
Restlessness, irritability and trouble sleeping.
A visible lump or fullness at the front of the neck.
A feeling of food or pills getting stuck.
Pressure on the windpipe, often worse when lying down.
Tiredness and weak muscles.
TAE is a minimally invasive, image-guided procedure that reduces the blood supply to the thyroid gland. With less blood flow, an enlarged gland can shrink and its hormone production may settle over time.
A small catheter is passed through the wrist or groin and guided to the arteries that feed the thyroid. Tiny embolic particles are then delivered into them, with no incision on the neck.
General comparison. The right option depends on your thyroid condition, test results and health, so your doctor will advise you.
| TAE | Thyroid surgery | Radioiodine | |
|---|---|---|---|
| Approach | Catheter, small puncture | Surgery on the neck | Radioactive iodine dose |
| Cut on the neck | None | Yes | None |
| Thyroid gland | Kept, blood supply reduced | Partly or fully removed | Gland activity reduced |
| Hospital stay | Short | Typically longer | Usually none |
TAE may be considered if you:
Suitability is decided after a consultation, blood tests and imaging.
Thyroid blood tests and ultrasound, with other imaging if needed, assess your gland and its arteries.
A tiny catheter enters an artery at the wrist or groin, usually under local anesthesia.
Guided by X-ray imaging, tiny particles are delivered into the thyroid arteries to reduce blood flow.
You are monitored in hospital and most patients go home within about a day.
What to expect once you are home.
Neck soreness, mild discomfort or a low fever may occur temporarily. Most people resume light activities within a few days.
The gland gradually reduces in size and symptoms may improve. Your doctor will monitor your thyroid levels.
Regular thyroid blood tests and ultrasound are usually advised, and medicines may need adjusting.

Guidance before and after your procedure.
TAE is used to reduce the blood supply to an overactive or enlarged thyroid. Your doctor will tell you whether it suits your condition.
No. The catheter is inserted through a small puncture at the wrist or groin.
It is usually done under local anesthesia. Neck soreness, mild discomfort or a low fever can occur afterwards and is managed with medication.
Most patients stay a short time, often about a day. Your doctor will confirm this for you.
Possibly. Your thyroid levels are checked with blood tests after the procedure, and medicines may need to be adjusted.
The gland shrinks gradually over weeks to months, and symptoms may improve over this time.
Like any procedure, TAE has risks, such as neck pain, fever, a temporary change in thyroid symptoms or, rarely, injury to nearby structures. Your doctor will explain these and whether TAE is right for you.
Book a consultation to find out whether TAE is right for you.
