【摘要】 目的 评估MRI引导高强度聚焦超声(MRgHIFU)完全消融子宫肌瘤的可行性、安全性和远期疗效。方法 对43例(平均年龄41.4岁)共51个子宫肌瘤,平均大小为(7.1 ± 1.4)cm,均进行一次MRI引导高强度聚焦超声消融术。治疗后即刻MRI增强测量靶肌瘤的体积及其无灌注区的体积,子宫肌瘤无灌注区的完全覆盖靶肌瘤为完全消融。对完全消融的子宫肌瘤在治疗后3个月、6个月、1年、2年和3年通过MRI进行随访复查肌瘤的体积变化;在术前、3、6个月采用UFS QOL症状评分方法对患者症状评分,并随访3年观察其症状的变化。同时对这些肌瘤的特征、治疗后不良事件、聚焦超声能量及治疗效率等进行了分析。结果 经MRgHIFU治疗后肌瘤平均消融率为84.3% ± 15.7%(范围33.8% ~ 100%),肌瘤部分消融(消融率 < 90%)、几乎完全消融(消融率为90% ~ 99%)和完全消融的病例分别为23例、10例和10例,平均治疗时间为(2.2 ± 0.8)h(范围1.0 ~ 4.3 h),治疗后均未发生并发症。10例13个完全消融的肌瘤术前MRI均为T2低信号表现而其血供类型不同;超声治疗的能效因子(EEF)为:(3.6 ± 2.1)J/mm3(0.7 ~ 6.8 J/mm3)。治疗后3、6个月症状严重程度评分(SSS)分别为从术前的33.9 ± 7.1下降至16.6 ± 9.0和 8.1 ± 3.4(P < 0.01),1年或2年后10例患者的症状完全消失。治疗后3、6个月和3年肌瘤体积分别缩小39.5% ± 10.2%、59.1% ± 9.0%和93.3% ± 3.1%(P < 0.01)。治疗后3年随访肌瘤均未出现复发。结论 MRI引导高强度聚焦超声完全消融子宫肌瘤是可行的、安全的和有效的,MRI T2WI低信号肌瘤可在治疗后取得完全消融。
