Arterial Embolization of the Shoulder

Struggling With Frozen Shoulder Pain?

Frozen shoulder—also called adhesive capsulitis—causes stiffness, deep shoulder pain, and limited movement that can last for months or even years.

If physical therapy, injections, or medications haven’t worked, Arterial Embolization of the Shoulder (AES) may offer relief without surgery.

Arterial Embolization of the Shoulder (AES) is a minimally invasive treatment that helps reduce chronic
shoulder pain that has not improved with other treatments.

What Is Frozen Shoulder Syndrome?

Frozen shoulder occurs when the connective tissue surrounding the shoulder joint becomes inflamed and tight. Over time, this inflammation leads to adhesions that restrict movement and cause persistent pain.

Common symptoms include:

Dull, aching pain deep in the shoulder
Stiffness and difficulty lifting the arm overhead
Loss of shoulder range of motion
Pain radiating down the front or side of the upper arm
Pain that worsens at night, especially when lying on the shoulder
Trouble reaching behind the back
Limited outward rotation of the arm
Muscle spasms
Shoulder weakness

What Is Arterial Embolization of the Shoulder (AES)?

Arterial Embolization of the Shoulder (AES) is a minimally invasive procedure used to treat frozen shoulder syndrome by targeting the inflammation causing pain and stiffness.

In frozen shoulder, abnormal blood vessels form around the shoulder joint capsule. These vessels fuel chronic inflammation, leading to pain, thickening of the joint capsule, adhesions, and reduced range of motion.

AES works by shutting down those abnormal vessels—while preserving healthy blood flow.

How AES Works

A small tube called a catheter is inserted into a blood vessel in the wrist under local anesthesia
Using real-time imaging, the catheter is guided to the abnormal blood vessels near the shoulder capsule
A medication is delivered to block these vessels, reducing excess blood flow
With inflammation reduced, pain decreases and movement improves
All healthy blood supply to the shoulder remains intact.

Why AES Is Different

Targets the source of inflammation, not just symptoms
No surgery or joint manipulation
Outpatient procedure
Same-day discharge
Faster recovery than surgical options

Is AES Safe?

Yes. Although AES is a newer treatment option, it is considered a safe and effective non-surgical alternative for patients with frozen shoulder syndrome.

The procedure is performed by our trained specialists using precise image guidance to maximize safety and accuracy.

What Is Recovery Like After AES?

You return home the same day
A driver is required after the procedure
Light activities may resume within one week
Avoid high-impact activities for at least two weeks
Recovery is typically much faster than surgical treatments.

How Quickly Does Pain Improve?

Pain relief may begin:

Immediately after AES, or
Within the first week

Many patients continue to notice gradual improvement in comfort and shoulder movement over the following weeks.

Does AES Provide Long-Term Relief?

Yes. Clinical outcomes show that 70- 90% of patients experience:

Significant pain reduction
Improved shoulder function
Increased range of motion

Is Arterial Embolization of the Shoulder Covered by Insurance?

Yes. Most health insurance plans cover AES.
Our team can help confirm your coverage before treatment.

Who Is a Good Candidate for AES?

You may be a good candidate if you:

Are between 30–80 years old
Have experienced frozen shoulder pain for more than 6 months
Have tried conservative treatments without improvement
Want to avoid shoulder surgery
Are not a good surgical candidate
Prefer a faster recovery with less downtime
