Genicular Artery Embolization to Reduce Pain Associated With Unilateral Mild to Moderate Osteoarthritis

"Genicular artery embolization (GAE) is a new, minimally invasive investigational not yet approved therapy. In previous studies, this procedure has provided pain relief in patients with mild to moderate OA in the short to midterm. We will be utilizing the Terumo Hydropearl® microspheres particle beads during the GAE procedures. The procedure will take place utilizing fluoroscopic and ultrasound guidance. Following catheterization of the femoral artery, angiography of the affected limb will be performed to define the genicular arterial anatomy. Genicular arteries demonstrating abnormal vascularity and corresponding to the site of the patient's pain will be catheterized and embolized using microspheres. Prior to and after embolization, parametric imaging will be performed utilizing proprietary software to quantify changes in blood flow to the target area~The intended use of the Terumo Hydropearl® microspheres device is to embolize the geniculate artery branch."
