Study summary

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

  33. Change From Baseline in Ghent University Scoring System (GUSS) at Month 6

    The Ghent University Scoring System (GUSS) is a radiographic scoring method specifically developed to evaluate joint damage in hand osteoarthritis. It focuses on assessing both structural damage and remodeling features visible on hand X-rays. Erosive progression and signs of repair or remodelling are scored by indicating the proportion of normal subchondral bone, subchondral plate and joint space on an 11-point rating scale (range 0-100 with 10 unit increases). A lower score indicates greater damage or remodeling. The total score is the sum of these 3 scores for the joint under consideration.

The wavelength chosen will be 785 nm and the laser head will be positioned between 15 and 20 centimetres above the hands (with a resolution of \~ 6.9 pixels/ cm2). Cutaneous blood flow in the areas of interest will be expressed as PU (perfusion unit) and/or CVC (cutaneous vascular conductance). The area of interest will be the whole hand and the area around each hand joint.

    Time frame: Before embolisation and 0, 15, 30, 45, 60, 75, 90, 105 and 120 minutes post embolisation
