摘要

Purpose

The study reports the initial experience in transarterial embolization (TAE) using an ethiodized oil-based emulsion for patients with refractory shoulder pain, focusing on safety, pain reduction, and functional improvement.

Methods

This is a retrospective, multicenter study including 23 patients treated with TAE using an ethiodized oil-based emulsion between April 2021 and May 2024. Clinical outcomes were assessed using visual analog scale (VAS) scores for pain (0–100 mm) and QuickDASH (0–100) scores (Disability of the Arm, Shoulder and Hand) for functionality. Adverse events were recorded and classified.

Results

The primary etiology of shoulder pain was adhesive capsulitis (61%), followed by bursitis (39%). Median follow-up was 87 days (range: 27–1088 days). Mean VAS score decreased from 65 mm (± 22) at rest, and 82 mm (± 13) during mobilization to 30 mm (± 27) at rest, and 36 mm (± 24) during mobilization at the last follow-up (p < 0.05). Mean QuickDASH score improved from 67 (± 17) pre-procedure to 43 (± 25) post-procedure (p < 0.05). No major complications occurred, and minor adverse events included one radial artery thrombosis (4%) and one puncture site hematoma (4%).

Conclusion

TAE of the shoulder using an ethiodized oil-based emulsion is safe and effective, warranting further investigation in larger studies.
