Clinical results of ultrasound-guided intra-arterial embolization targeting abnormal neovessels for plantar fasciitis: 66 cases with up to 4 years of follow-up.

BACKGROUND

Plantar fasciitis (PF) is the most common cause of chronic heel pain, affecting young and older patients.

METHODS

This retrospective study included patients with PF refractory to conservative treatment who underwent intra-arterial embolization of abnormal neovessels. All patients received temporary embolic material through a needle percutaneously inserted into the posterior tibial artery. The numeric rating scale (NRS) pain score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and procedure-related adverse events were evaluated.

RESULTS

Between January 2020 and February 2022, 66 patients with PF were treated with intra-arterial embolization without major adverse events. The NRS pain score improved significantly, and the AOFAS score increased from 65.8 pre-treatment to 92.8 at 1 year post-treatment. The treatment effect was maintained until the final follow-up (mean duration: 30.9 months).

CONCLUSIONS

Ultrasound-guided intraarterial embolization using temporary embolic material may be effective for PF.
