BACKGROUND/AIM: We aimed to investigate the role of Shearwave Elastography (SWE) in the evaluation of response to uterine artery embolization (UAE) in patients with uterine leiomyomas.
SWE images of the dominant uterin leiomyomas were obtained before and 1.5 months after performing UAE in 33 women suffering from symptoms due to leiomyomas (menometrorrhagia, bulk related symptoms, pelvic pain). Leiomyomas were also evaluated by 2 observers for location and longest diameter in axial plane. Interobserver agreement in the quantitative SWE analysis was calculated using intraclass correlation coefficients.
Thirty-three women (mean age, 39.7 years; range, 31–48 years) were examined with SWE 1.5 months after UAE. After treatment, 3 patients (9.1%) had fever, 1 patient had nausea and 29 patients (87.9%) had no complications. The post UAE stiffness measurements of leiomyomas (mean SWE ± SD = 13.34 ± 3.9kPa) were significantly lower than the pre UAE measurements (mean SWE ± SD = 17.16 ± 4.8kPa) (P < 0.001). There was excellent agreement between the 2 blinded observers in SWE measurements.
SWE values of leiomyomas after UAE significantly decreased. SWE, with its high reproducibility, could become a useful tool in the follow up of uterin leiomyomas after UAE.
背景/目的：我们旨在研究剪切波弹性成像（SWE）在评估子宫肌瘤患者子宫动脉栓塞术（UAE）反应中的作用。
对 33 名因子宫肌瘤（月经过多、肿块相关症状、盆腔疼痛）而出现症状的女性进行 UAE 前后 1.5 个月的优势子宫肌瘤的 SWE 图像采集。观察者 2 名还对肌瘤在轴位上的位置和最长直径进行评估。采用组内相关系数计算定量 SWE 分析的观察者间一致性。
33 名女性（平均年龄 39.7 岁；范围 31-48 岁）在 UAE 后 1.5 个月进行 SWE 检查。治疗后，3 名患者（9.1%）出现发热，1 名患者出现恶心，29 名患者（87.9%）无并发症。子宫肌瘤 UAE 后的僵硬测量值（平均 SWE ± SD = 13.34 ± 3.9kPa）明显低于 UAE 前的测量值（平均 SWE ± SD = 17.16 ± 4.8kPa）（P < 0.001）。两名盲法观察者在 SWE 测量方面具有很好的一致性。
UAE 后子宫肌瘤的 SWE 值显著降低。SWE 具有很高的可重复性，可能成为 UAE 后子宫肌瘤随访的有用工具。
