Efficacy of radiation synovectomy (radiosynovectomy or radiosynoviorthesis) with yttrium-90 in exudative inflammation of synovial membrane of knee joints in patients with rheumatic diseases – preliminary report

摘要

ObjectivesHypertrophic and exudative synovitis of the knee is one of the earliest symptoms in rheumatic diseases. In the case of pharmacotherapy failure, other methods which directly remove the inflamed synovial membrane are used – synovectomies. Radiosynovectomy (RSV) is the radiopharmaceutical application of colloidal solution to joint cavities. In this study, the authors assessed the efficacy of knee radiosynovectomy with yttrium-90 (Y-90) in several groups of patients divided into certain rheumatic diseases.
