ABSTRACT
Objective:To explore the safety and efficacy of high intensity focused ultrasound in the treatment of endometrioma. Methods:Sixteen typical patients with endometrioma received HIFU treatment.HIFU treatment was monitored by real-time ul- trasound.The changes of tumor-size and blood-supply of endometrioma before and after HIFU were evaluated by the CDFI or enhanced MRI,and symptoms changes were recorded in follow-up process.Results:After HIFU treatment,in all patients,tumor size shrank 57.16%,blood supply decreased,menstrual cycle and menstrual period decurtated,and menstrual volume decreased 50%.All the patients had a complete remission of menalgia and Hb test became normal level.All the patients had no serious syndrome.Conclusion:HIFU is safe and effective to treat endometioma.
