| 目 的 探讨超声引导下射频消融（RFA）治疗中子宫肌瘤的三维彩色血流分组及回声水平对消融时间、消融针数的影响。
方 法 对48例行RFA治疗的子宫肌瘤患者进行分组，根据三维彩色血管能量成像将其分为乏血供组、富血供两组，再根据回声水平的不同，分为高回声组、低回声组及混合回声组，分别记录每组消融时间、消融针数并比较整个治疗过程的消融时间、消融针数是否存在差异。
结 果 两组中高回声组平均消融时间及平均消融针数均明显低于低回声组，混合回声组处于两者之间，差异均有统计学意义（p＜0.05）。同一回声水平组比较，乏血供组的平均消融时间明显低富血供组；乏血供组的平均消融针数明显少于富血供组，两组比较平均消融时间及平均消融针数差异均有统计学意义（p＜0.05）。
结 论 RFA治疗中与乏血供高回声的子宫肌瘤相比较，富血供低回声组子宫肌瘤消融时间相对长、消融针数相对多。可指导操作者在RFA治疗时，对不同类型的子宫肌瘤进行有针对性的布针消融，预计消融时间及消融针数，避免消融不彻底或消融过度。 |

| Abstract: |
| ABSTRACT Objective To investigate the effects of 3D color doppler grouping and echo level in the RFA treatment guided by ultrasound of uterine fibroids on ablation time and numbers of needle.
Methods The 48 patients with uterine fibroids treated by RFA were divided into hypovascular and hypervascular groups according to 3D color power angiography, and into hyperechoic, hypoechoic and mixed groups according to echo level. Record the ablation time and numbers of needle of each group, and discuss if there is difference in the whole treatment.
Results The mean ablation time and numbers of needle of hyperechoic group were significantly lower than those of hypoechoic group, and those of mixed group were between hyperechoic and hypoechoic groups. The differences were statistically significant(p<0.05). At the same echo level, the mean ablation time and numbers of needle of hypovascular group were significantly lower than those of hypervascular group. The differences were statistically significant(p<0.05).
Conclusions Compared with hypovascular and hyperechoic uterine fibroids in RFA treatment, the ablation time of hypervascular and hypoechoic uterine fibroids was longer and the numbers of needle were more. This can guide the operator targeted arrange the needles in RFA treatment according to different types of uterine fibroids, and predict ablation time and numbers of needle to avoid insufficient or excessive ablation. |
