目的探讨超声在子宫肌瘤射频治疗中的应用价值。方法术前超声确定肌瘤大小、部位,术中准确引导并动态观察射频针的位置,术后复查肌瘤大小及血流信号的变化情况。结果120例患者中肌瘤结节151个,其中26个黏膜下肌瘤,均取出或排出;98个壁间肌瘤,4个术后一个月内自行从阴道排出;94个壁间肌瘤和9个宫颈肌瘤及18个浆膜下肌瘤术后半年较术前缩小约70%～75%;1例浆膜下、多发子宫肌瘤(小于2cm)穿孔。结论超声在子宫肌瘤射频治疗术前筛查患者、术中定位、术后监测随访等均具有重要作用。 Objective To investigate the value of ultrasound in radiofrequency treatment of uterine fibroids. Methods The size, location and position of the fibroids were accurately determined by preoperative ultrasound. The position of the RF needle was accurately guided and observed dynamically. The size of fibroids and the changes of blood flow signals were reviewed. Results Of the 120 patients, 151 myoma nodules were found, of which 26 were submucosal fibroids, all of which were removed or excreted. Ninety-nine intramural fibroids were excreted in the vagina within four months after operation. Ninety-four intramural fibroids And nine cervical fibroids and 18 subserosa fibroids half a year after surgery to reduce about 70% to 75%; 1 subserosal, multiple uterine fibroids (less than 2cm) perforation. Conclusion Ultrasound in the screening of patients with uterine fibroids before radiofrequency treatment, intraoperative positioning, postoperative follow-up monitoring plays an important role.
