%X La radiosinovectom¨ªa es una forma local de radioterapia utilizada como tratamiento de segunda l¨ªnea en el manejo de artropat¨ªas inflamatorias y no inflamatorias con respuesta insatisfactoria a la terapia sist¨¦mica o local con corticoesteroides. Tiene una eficacia similar a la sinovectom¨ªa quir¨²rgica, con las ventajas de ser un tratamiento de menor costo, menos cruento y con menor tiempo de convalecencia. Su eficacia es mayor en artropat¨ªas inflamatorias caracterizadas por sinovitis, como la artritis reumatoide y artritis cr¨®nica juvenil, con compromiso mono u oligoarticular y en articulaciones de extremidades superiores. Existen m¨²ltiples is¨®topos que se pueden utilizar en suspensiones coloidales, siendo el sulfuro coloidal de renio-186 el utilizado para la articulaci¨®n radiocarpiana. Una t¨¦cnica de administraci¨®n adecuada es fundamental para el ¨¦xito del tratamiento, siendo la inyecci¨®n con gu¨ªa ultrasonogr¨¢fica adecuada para articulaciones de volumen peque o, instancia en la que la colaboraci¨®n del m¨¦dico radi¨®logo entrenado es fundamental. Radiosynovectomy is a local form of radiotherapy used as second-line treatment in the management of inflammatory and non-inflammatory arthropathies with unsatisfactory response to local or systemic corticosteroid therapy. Its efficacy is similar to that of surgical synovectomy, with the advantages of being a low-cost and minimally- invasive treatment that requires a shorter recovery time. Its efficacy is greater in the treatment of inflammatory arthritis characterized by synovitis, such as rheumatoid arthritis and juvenile chronic arthritis with mono/ oligoarticular involvement, especially in upper extremity joints. A number of isotopes can be used in colloidal suspensions. Rhenium-186-sulphide colloid is currently indicated for the treatment of medium-sized joints. The ultrasound-guided injection is suitable for small joints, such as wrist. For proper and safe use and administration of this technique the collaboration of a trained and experienced radiologist is critical to successful treatment.
