【Osteoarthritis of the Finger】【Transarterial Microembolization (TAME)】 Successful Case Sharing

Ms. S, 51 years old, had been experiencing pain in the second and fourth fingers of her right hand for over three years. After seeking medical attention, she was diagnosed with "distal interphalangeal joint degenerative arthritis." She received medication, but the pain did not significantly improve. Ms. S then visited the National Cheng Kung University Hospital Interventional Medical Center for further discussion with Bow Wang, M.D..

After discussion, Bow Wang, M.D. ultimately chose to perform "transarterial embolization (TAE) for Ms. S." Guided by X-ray fluoroscopy and under local anesthesia, a radial artery in the hand was punctured.

A microcatheter was inserted into the painful area. Under arterial angiography, a contrast agent was injected to locate the corresponding finger vein. Embolizing medication was then injected through the microcatheter. After the embolization was completed, the pain significantly improved two weeks after the treatment.

However, Bow Wang, M.D. cautioned that TAE for "digital osteoarthritis" has limitations. The main indication is a pain index exceeding 5 points, and patients who have not shown significant improvement after more than three months of various treatments.

This treatment is not suitable in the following situations:

1. Severe tendon or ligament damage or rupture

2. Pain accompanied by other nerve compression symptoms, such as numbness

3. Poor kidney function (eGFR < 30 mL/min/1.73m2)

4. Low platelet count, abnormal coagulation function

5. The patient is unable to lie flat for two hours.

6. Pregnancy

Treatment side effects may include local hematoma and bruising at the puncture site; temporary local discoloration at the embolization site may occur, which will improve and disappear within several days to a month.

It is recommended that patients undergo a detailed evaluation by a physician to confirm the true source of pain, and have a thorough discussion with their doctor and family to understand the treatment process and related precautions before receiving treatment for better assurance.
