Abstract:
Objective To assess the efficacy of high intensity focused ultrasound (HIFU) for the ablation of feeding-artery in uterine fibroids.Methods A total of 45 women with uterine fibroids who had children accepted HIFU treatment.Color Doppler and contrast-enhanced ultrasound were used to target the supply vessels entered the fibroid.HIFU treatment was focused primarily on locations where supplying vessels entered the fibroid.Conventional ultrasound,color Doppler ultrasound,contrast-enhanced ultrasound and MRI were performed before and after HIFU treatment to observe the changes of imaging.Results After HIFU treatment,the volume of uterine fibroids decreased to certain extent.The blood signals decreased or disappeared in the treated regions.Bewteen two groups of the uterine fibroids diamete ≥5 cm and ＜5 cm,there were significant differences in the percentage of the nonperfusion regions in the volume of uterine fibroids (≥70％,P ＜0.05).Conclusions Ablation of feeding artery by HIFU is an effective treatment for the uterine fibroids.HIFU treatment is effective for the ablation of feeding-artery in uterine fibroids whose diameter less than 5 cm.
