FAIRFAX, Va., June 15, 2020 /PRNewswire/ -- A new nonsurgical treatment decreases errant blood flow in the

shoulder to quickly reduce pain and improve function in patients with adhesive capsulitis, also known as "frozen

shoulder," according to research presented during a virtual session of the Society of Interventional Radiology's

2020 Annual Scientific Meeting on June 13. Frozen shoulder gradually causes significant pain and stiffness of the

shoulder joint in an estimated 200,000 people in the U.S. each year. The symptoms are often treated with physical

therapy or pain medications, until they resolve within one to three years.

In this Phase II FDA-approved Investigational Device Exemption clinical trial on arterial embolization of the

shoulder (AES), interventional radiologists inserted a catheter through a pinhole-sized incision in patients' wrists

that was used to feed microsphere particles into as many as six arteries in the shoulder to reduce inflammation.

The treatment was conducted on an outpatient basis and took approximately one hour. Each patient's pain,

disability, and blood flow in the shoulder were measured before and after the treatment using three scales, in

addition to MRI imaging to visualize the shoulder joint.

The treatment was successfully completed in 16 patients whose symptoms had not responded to conservative

treatment over 30 days. Minor adverse events such as temporary skin discoloration were reported in nine patients.

One month later, researchers followed the progress of 11 patients and found that pain significantly decreased after

AES (-57 mm on the Visual Analog Scale) and improved physical function in all patients (+28 mm on the Single

Assessment Numeric Evaluation and +30 mm on the American Shoulder and Elbow Surgeons Shoulder Score).

Additional progress was reported at the three-month follow up.

Lead author, Sandeep Bagla, MD, CEO of Vascular Interventional Partners, NOVA, noted that this treatment is still

investigational and that conservative therapies should still be considered first. Additionally, there are several

important limitations of the research, including small sample size and lack of control arm.

Additional information about the clinical trial is available at ClinicalTrials.gov, using the identifier NCT03676829.

The trial is funded through Terumo Medical Corporation, a medical device company.
