Evaluation of the Safety of LipiodolⓇ Embolization in Symptomatic Digital Osteoarthritis Refractory to Conventional Treatment

The goal of this clinical trial is to evaluate the safety of arterial embolization using Lipiodol® in patients with symptomatic hand osteoarthritis refractory to conventional treatment. It will also learn about the efficacy of arterial embolization with Lipiodol® in reducing pain and improving hand function. The main questions it aims to answer are: * What are the side effects and complications associated with the Lipiodol® arterial embolization procedure? * Does arterial embolization reduce pain intensity and improve hand function? Researchers will evaluate patients over a 6-month period to assess the safety of Lipiodol® embolization and its impact on joint pain, swelling, and functional capacity. Participants will: * Undergo arterial embolization with Lipiodol® * Participate in regular follow-ups to monitor pain relief, hand function, and any side effects * Have imaging studies to assess changes in joint vascularisation and damage
