Abstract: | PurposeTo evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for the treatment of chronic inflammatory joint pain via systematic review and meta-analysis.Materials and MethodsMEDLINE and EMBASE databases were searched for studies reporting outcomes in patients with chronic inflammatory joint pain treated with TAE. Meta-analyses of pain score changes, changes in proportions of patients on analgesic medications, range of motion changes, technical success rates, and adverse events rates were performed. Subgroup analyses were conducted with respect to pain site (knee versus shoulder).ResultsFourteen observational studies, which included 346 patients, were reviewed. The pooled technical success rate was 95.8%, and no major adverse events were observed. The pooled mean difference in pain score at 1 week was 3.1. At 1, 3, and 6 months, the difference in score was 4.0, 4.2, and 5.1, respectively. At 1 year, the difference was 5.5. Subgroup analysis demonstrated that shoulder embolization was associated with greater reduction of pain than knee embolization at 3 and 6 months (P < .001 and P = .018, respectively), whereas there was no significant difference between the sites at 1 month (P = .734). The pooled proportions of patients on analgesic medication at baseline and at 1, 3, 6, and 12 months were 81.1%, 36.3%, 42.3%, 28.2%, and 22.4%, respectively. The pooled estimated increase in the range of motion among patients who underwent shoulder embolization was 55.6° for anterior elevation and 64.7° for abduction.ConclusionsTAE is an effective and safe therapeutic option for patients with chronic inflammatory joint pain. |
