TAME Micro-arterial Embolization FAQ: Cost, Hospitalization, Recurrence, and Postoperative Rehabilitation

TAME (Transcatheter Arterial Microembolization) is used to treat chronic pain associated with abnormal microvascular proliferation.
Its original method was catheter-based C-TAME (standard type), which later evolved into ultrasound-guided s-TAME (simplified type). XIYI performs catheter-based C-TAME, using the GE OEC 3D mobile C-arm with cone-beam CT (3D tomography), performed by Director Lu Bing-sheng, and holds the trademark license for Okuno Clinic in Taiwan.

This page compiles the most frequently asked questions in outpatient clinics, providing answers for each question first, with links to corresponding articles for details that require closer examination. Whether you are suitable for treatment must be evaluated and decided by a doctor.

What is TAME?

An interventional treatment for chronic inflammatory pain. Injured, strained, or degenerated tissues may grow abnormally proliferated microvessels, accompanied by newly formed nerve endings that continuously send out pain signals; TAME reduces blood flow in these vessels, aiming to reduce the source of pain signals. For a complete explanation of the principles, applicable conditions, and treatment process, please see "What is TAME (Transcatheter Arterial Microembolization)?".

What is the difference between C-TAME and s-TAME?

The difference lies in the method of entry and positioning. C-TAME is the original standard method, performing selective embolization using microcatheters under angiography guidance, which can handle deeper areas or areas with complex vascular pathways; s-TAME is a simplified version developed later, completed by ultrasound-guided injection, used for more superficial areas. The division of labor between the two is based on the depth of the area, and which one is actually suitable is determined by the doctor based on imaging; some clinics in the market only offer one of them, so it is worth asking clearly before evaluation. For a complete comparison and selection criteria, please see "What is the difference between C-TAME and s-TAME?".

Who needs a careful evaluation by a doctor first?

Those who are allergic to contrast media or medications, have poor renal function, are taking anticoagulants or antiplatelet drugs, and whose pain location is close to vital blood vessels, need to be evaluated by a doctor first to see if they are suitable and which method is suitable. For a detailed discussion of the four groups of people and pre-operative evaluation, please see "Who is not suitable for TAME (Transcatheter Arterial Microembolization)?".

I am taking anticoagulants, can I do it?

Please inform your doctor of your current medications first, and do not stop taking medications on your own. Whether medication needs to be adjusted and for how long will be determined by the doctor based on your medication type and the original indications. This is something that will definitely be asked during the evaluation, so please bring your medication list with you to the consultation room.

How is the treatment performed? Is hospitalization required?

Hospitalization is not required. Both C-TAME and s-TAME are outpatient procedures: C-TAME involves percutaneous insertion of a microcatheter under local anesthesia, followed by embolization of the target vessel under image guidance; s-TAME is completed by injection under ultrasound guidance. The patient is awake during the process, and after completion, will be observed in the clinic with pressure applied to the puncture site to stop bleeding, and return home on the same day.

Is it covered by National Health Insurance? How is the fee calculated?

Currently, it is a self-pay item. The cost varies depending on the treatment site, scope, and the method used (C-TAME or s-TAME). It will be explained after the evaluation and before the treatment, and will not be informed only on the day of the procedure.

How long is the recovery period after treatment?

The puncture site usually heals within a few days, and it is recommended to avoid lifting heavy objects or weight-bearing activities for one to two weeks after the procedure.

The response time of the treated area varies from person to person. Some people feel changes within a few weeks, while others need longer, which will be followed up and evaluated by the doctor. Actual activity restrictions will vary depending on the site, method, and work type, and will be explained before treatment.

I have had PRP or hyaluronic acid injections, can I still do TAME?

Yes, past injections do not affect eligibility for evaluation. However, please bring your treatment records, such as what was injected, how many times, what the reaction was at that time, and how long the effect lasted. These are very useful for determining the source of pain.

Will the effect last? Will it recur?

The effect varies by person and site, and there are cases where improvement is limited. Abnormal blood vessels may regenerate, and if symptoms reappear in the future, the doctor can evaluate whether repeated treatment is appropriate. Any claim that it is definitely effective or will definitely not recur is invalid.

Should it be paired with physical therapy after treatment?

It is recommended to combine them. TAME addresses the link of abnormal blood vessels, but joint mobility and muscle strength still need to be established through physical therapy, which also helps reduce the chance of recurring pain. Please follow the recommendations of your doctor and therapist.

How to evaluate if I am suitable?

If your pain has persisted for more than half a year, and the effects of medication, physical therapy, or injections are limited, you can conduct a pre-evaluation through LINE first. Please bring your past imaging data (X-ray, MRI, ultrasound) and treatment records during your visit, and the doctor will confirm the source of pain before discussing the suitable method.
