Sonography-guided OK-432 sclerotherapy for benign thyroid cysts

Abstract

Five of the 20 cases were excluded for various reasons. Eleven of the remaining 15 cases (73.3%) showed good responses (<10 mm in diameter), whereas the other 4 patients showed poor responses. All patients tolerated the therapy well, and no significant morbidity or complication occurred among patients treated by OK-432 sclerotherapy.
