Genicular Artery Embolization (GAE) for the Treatment of Chronic Post Knee Arthroplasty Pain

"Embozene Microspheres are manufactured by Varian Medical Systems (Palo Alto, CA). These microspheres are non-resorbable hydrogel microspheres coated with polyzene-F. Embozene microspheres are approved for use in treating arteriovenous malformations, hypervascular tumors such as uterine fibroids and hepatomas, and prostatic arteries in patients with benign prostatic hyperplasia.~One of the causes of chronic pain in the setting of a knee arthroplasty may be increased blood flow to the specific area(s) of pain. The purpose of this procedure is to reduce blood flow (embolize) to specific parts of the knee which are contributing to your pain.~This procedure is performed by infusing the Embozene particles into specific knee arteries (genicular arteries) in the region of knee pain."
