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

Phase 1
Recruiting
Conditions
Osteoarthritis
Interventions
Drug: embolization therapy
Registration Number
NCT06611007
Lead Sponsor
University Hospital, Grenoble
Brief 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

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

A PeriCam PSI device (Perimed, Sweden) will be used to assess skin perfusion in both hands. The image size will be set at 30 x 20 centimetres and the acquisition speed at one image per second. 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.
