Thumb Embolization
A Non-Surgical Solution for Basilar Thumb Arthritis. Thumb Embolization is a minimally invasive procedure that reduces pain from thumb arthritis by blocking tiny abnormal blood vessels in and around the arthritic joint. These abnormal vessels increase inflammation and nerve sensitivity.

Overview of Thumb Embolization
Basilar thumb arthritis (also known as CMC joint arthritis) affects the base of the thumb, where the first metacarpal bone meets the wrist. It’s one of the most common forms of arthritis in the hand—especially in women over 40.
As the cartilage in the joint wears down over time, the bones rub together, causing:
- Pain when pinching, gripping, or turning objects
- Swelling or tenderness at the base of the thumb
- Reduced hand strength and mobility
- Difficulty doing everyday tasks like opening jars, writing, or using tools
If you’ve tried splints, anti-inflammatories, injections, or physical therapy with little relief, you may be a candidate for Thumb Embolization—a cutting-edge, non-surgical treatment to reduce pain and improve function.
What Is Thumb Embolization?
Thumb Embolization is a minimally invasive procedure that reduces pain from thumb arthritis by blocking tiny abnormal blood vessels in and around the arthritic joint. These abnormal vessels increase inflammation and nerve sensitivity.
By stopping the blood supply to those problematic vessels, embolization:
- Decreases inflammation
- Reduces nerve-related pain
- Slows further joint irritation
- Helps restore better thumb function
This procedure is performed by our skilled vascular specialists using a tiny catheter and advanced imaging—no incisions or joint surgery needed.
Benefits of Thumb Embolization
- Non-surgical – No cutting, implants, or joint replacement
- Minimal downtime – Return to light activity within 1–2 days
- Significant pain relief – Often within 2–6 weeks
- Outpatient procedure – Done right in our vascular center
- Long-lasting results – Many patients see improvement for months or years
- Preserves joint structure – Avoids permanent joint alterations
This is a great option for patients who want to avoid surgery—or who aren’t candidates for surgical thumb reconstruction.
The Thumb Embolization Procedure
At Advanced Vascular Centers, Thumb Embolization is performed in a modern outpatient setting by experienced specialists. Here’s what to expect:
1. Consultation & Imaging
We’ll confirm your diagnosis using imaging (such as X-rays, MRI, or ultrasound) and evaluate blood flow to the arthritic thumb joint to locate the problematic vessels.
2. The Procedure
- You’ll receive local anesthesia at the catheter insertion site (usually the wrist or arm)
- A tiny catheter is inserted into an artery and guided with real-time imaging to the vessels supplying the base of the thumb
- A special embolic agent (microscopic particles) is injected to block abnormal blood flow to the inflamed joint
- The catheter is removed and a small bandage is applied—no stitches required
3. Recovery
- You’ll go home the same day
- Resume light hand use within 24–48 hours
- Avoid heavy gripping or pinching for a short period
- Pain relief begins within 2 to 6 weeks and improves over time
What Results Can I Expect?
Patients often report:
- Reduced pain during hand use
- Less swelling and joint sensitivity
- Improved grip strength
- Better range of motion and daily function
Clinical studies and international experience with hand embolization show promising results—with 70–90% of patients experiencing lasting pain relief.
Risks and Complications
Thumb Embolization is considered safe and low risk, especially when performed by a trained interventional specialist. However, as with any medical procedure, some risks exist.
Common, mild side effects:
- Bruising or soreness at the catheter site
- Temporary hand or thumb stiffness
- Mild swelling or fatigue in the hand
Rare complications:
- Non-target embolization (blockage of nearby vessels)
- Temporary numbness or tingling in the thumb
- Allergic reaction to contrast dye
- Infection at the catheter site (extremely rare)
Our team uses advanced imaging and specialized techniques to minimize these risks and ensure patient safety.
FAQS
What is Thumb Embolization?
Thumb Embolization is a minimally invasive, outpatient procedure that reduces chronic arthritis pain at the base of the thumb. It works by blocking abnormal blood vessels that fuel joint inflammation and nerve irritation—helping relieve pain and restore function without surgery.
How do I know if I’m a candidate?
You may be a candidate if you’ve been diagnosed with basilar (CMC joint) thumb arthritis, and conservative treatments like splints, anti-inflammatory medications, or steroid injections haven’t worked. A consultation and imaging at Advanced Vascular Centers will determine if you’re eligible.
Does the procedure hurt?
Most patients experience very little discomfort. The procedure is done using local anesthesia, and most people report only mild soreness afterward—similar to a blood draw or IV. There’s no need for general anesthesia or sedation.
How long does the procedure take?
The embolization usually takes about 45 to 60 minutes. After a brief recovery period, you’ll go home the same day and typically resume light hand use within 1–2 days.
When will I notice pain relief?
Many patients begin to feel less pain and stiffness within 2 to 6 weeks. Results often continue to improve over several months, as inflammation subsides and hand function improves.
Will the procedure affect the function of my thumb or hand?
No. The procedure is targeted only at the abnormal blood vessels causing inflammation—it doesn’t damage bones, tendons, or muscles. Most patients actually regain better grip strength and thumb mobility as pain decreases.
What are the risks or side effects?
Thumb Embolization is very safe. Minor side effects can include bruising, temporary hand soreness, or mild swelling. Rare risks include non-target embolization, temporary numbness, or contrast dye allergy, but these are uncommon with skilled care.
How long do the results last?
For many patients, relief from thumb embolization lasts months to years. While the procedure doesn’t reverse arthritis, it treats the root source of pain and inflammation, giving long-term improvement and often delaying or avoiding surgery.
