Three cases of complications after high-intensity focused ultrasound treatment in unmarried women

High-intensity focused ultrasound (HIFU) has been regarded as a non-surgical, minimally invasive therapeutic option for patients who prioritize uterus-conservation. Although many studies have shown that HIFU therapy is a safe and effective treatment of uterine fibroid, not all fibroids are suitable for HIFU due to risks of serious complications. We experienced three cases of complications after the HIFU ablation for huge uterine fibroids, including two cases of rapid myoma enlargement and one case of heavy vaginal bleeding.
