Objectives Adenomyosis is a common and refractory disease in gynecology. Preserving the uterus during treatment for adenomyosis remains a problem. High-intensity focused ultrasound (HIFU) is widely used in treatment of solid tumors. This study aimed to analyze patients with adenomyosis who were treated by HIFU and to preliminarily examine the characteristics of patients who are more suitable for HIFU to treat adenomyosis with reliable efficacy. Methods Over 2 years, 67 women who were diagnosed with adenomyosis and treated with HIFU at our gynecology department were included in this study. We investigated outcomes of their symptoms (dysmenorrhea and hypermenorrhea) and the volume of their uterine lesions. We also compared the patients’ clinical profiles. Results The women had a mean follow-up duration of 11.6 ± 0.46 months. In the numerical rating scale, used to assess the degree of dysmenorrhea, the score was significantly lower (mean difference: −1.94, 95% confidence interval: −2.704 to −1.176) 3 months after HIFU treatment compared with before treatment, then it remained stable for 3 to 12 months. Hypermenorrhea was reduced to a certain degree, with a mean difference of −0.54 (−1.01–0.02). Conclusions HIFU is a new noninvasive treatment method for adenomyosis that may help relieve dysmenorrhea.

Therapeutic application of ultrasound is of interest for a tumor treatment, thrombolysis, drag delivery, blood-brain barrier opening and so on. High-intensity focused ultrasound (HIFU) therapy has been developed as the noninvasive treatment deep cancers in particular. Issues as the defocusing and distortion of ultrasound in the body and the long treatment time in current HIFU should be resolved quickly. Numerical simulation is required for the early development of the advance HIFU system.

3082 Background: Chemotherapy-induced thrombocytopenia (CIT) contributes to treatment dose delay and/or modification, often resulting in poorer survival and disease progression. Compared with partial splenic embolization (PSE) and drugs, high-intensity focused ultrasound has the advantages as following: (1) it is a noninvasive treatment modality with potentially fewer adverse effects and complications; (2) the hospital stay and recovery time after treatment are short; (3) its cost is relatively low compared to surgery. The purpose of this work was to preliminarily investigate the efficacy and safety of high intensity focused ultrasound treatment of chemotherapy-induced thrombocytopenia (CIT) and hypersplenism. Methods: 26 patients with chemotherapy-induced thrombocytopenia and hypersplenism (15 male and 11 female; median age, 56 years; range, 51-66 years) were treated with ultrasound guided high-intensity focused ultrasound. Complications were recorded. Laboratory examination and magnetic resonance imaging were used to evaluate the efficacy. The spleen volume and ablation volume rate of the spleen were calculated by MRI after treatment. They were followed closely for at least 6 months. Results: After high-intensity focused ultrasound treatment, the MRI showed that the ablation area had turned into a non-perfused volume, the mean percent spleen ablation volume was 18.76% ± 6.1% (range, 11.17%-32.34%). After 6 months of HIFU ablation, the ablated area shrank evidently; the sunken spleen formed a lobulated shape and the splenic volume decreased. The platelet count increased 3-7 days after treatment and remained for 1-2weeks higher than baseline (53.33 ± 15.80 × 109/L). The white blood cell count and platelet count of the patients were substantially improved during the follow-up period. No substantial difference was observed in RBC counts between baseline and after treatment. In addition, symptoms such as epistaxis and gingival bleeding were ameliorated or even eliminated, and the quality of life was improved. Follow-up imaging showed a nonperfused volume in the spleen. Conclusions: For the first time to our knowledge, high-intensity focused ultrasound ablation was used to treat Chemotherapy-induced thrombocytopenia (CIT) and hypersplenism. High-intensity focused ultrasound ablation of the spleen may cause damage to a certain volume of the spleen parenchyma to achieve the purpose of hypersplenism treatment. High intensity focused ultrasound may be an effective and safe alternative for treatment of CIT and hypersplenism.
