目的探讨彩超在不同大小子宫肌瘤子宫动脉栓塞治疗后疗效观察中的应用价值。方法症状性子宫肌瘤患者68例,分为A组35例(子宫肌瘤最大径≤5cm)和B组33例(5cm<子宫肌瘤最大径<8cm),分别于子宫动脉栓塞治疗后3、6个月和12个月行超声检查,观察肌瘤的大小、内部回声及血流信号变化情况,比较治疗前后肌瘤体积缩小率和临床症状改善率。结果子宫动脉栓塞治疗后检查发现,子宫肌瘤的缩小率A组明显优于B组(P<0.05),两组中低回声组的子宫肌瘤缩小率最高,其次为等回声组和高回声组。临床症状的改善率A组亦明显优于B组。结论子宫肌瘤最大径≤5cm的症状性子宫肌瘤患者子宫动脉栓塞治疗后疗效较好,其中超声表现为低回声的效果更佳。 Objective To investigate the clinical value of color Doppler ultrasound in the treatment of uterine fibroids with different size and uterine artery embolization. Methods Sixty-eight patients with symptomatic uterine leiomyoma were divided into group A (n = 35), group B (n = 35), group B (n = 33) and group B , 6 months and 12 months underwent ultrasound examination to observe the size of the fibroids, internal echo and blood flow changes in the signal, before and after treatment of fibroids volume shrinkage and clinical symptom improvement rate. Results After uterine artery embolization examination, the reduction rate of uterine fibroids in group A was significantly better than that in group B (P <0.05). The shrinkage rate of uterine fibroids was the highest in both groups, followed by the group of equal echo and hyperechoic group. The improvement rate of clinical symptoms was also significantly better in group A than in group B. Conclusion Uterine fibroids in patients with uterine fibroids less than 5cm in diameter in the treatment of uterine artery embolization better curative effect, including ultrasound showed hypoechois better.
