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

Abstract

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. Level of evidence: IV.
