Purpose: To evaluate the mid-term clinical outcomes of transcatheter arterial embolization (TAE) for adhesive capsulitis (AC) resistant to medical treatments.

Materials and methods: This is a prospective analysis performed between February 2016 and February 2020. Inclusion criteria for TAE were shoulder pain, restriction of movement and no response to conservative treatment for at least 3 months. Demographic variables, risk factors, technical aspects, adverse events, changes by visual analogue scale (VAS) for pain and physical examination before and after TAE were assessed.

Results: This study included 40 patients with AC (35 women and 5 men; mean age 50 ± 9 years old). Abnormal vessels were observed in 31/40 (77.5%) procedures. As embolic agent, imipenem/cilastatin was used. The mean follow-up was 21.2 ± 10.5 months. Significant differences were obtained in terms of pain reduction before and 6 months after TAE with the median visual analogue scale (VAS) of 8 vs. 0.5, P = 0.0001. Substantial differences were found regarding mobility in flexion and abduction before and 6 months after embolization, respectively (79.5° ± 18.5° vs. 133° ± 24.5°, P = 0.0001; 72.4° ± 18.8° vs. 129.7° ± 27.9°, P = 0.0001). No complications occurred. Complete recovery was obtained in 37/40 (92.5%) patients and partial recovery in 2/40 (5%). No clinical recurrence appeared.

Conclusions: Clinical results of transcatheter arterial embolization with imipenem/cilastatin are effective and stable in the mid-term follow-up for patients presenting with AC resistant to conservative treatments.
