目的 探讨超声造影(Contrast Enhanced Ultrasound,CEUS)及三维彩色能量成像(three dimensional color power angiography, 3D-CPA)指导射频消融(radiofrequency ablation,RFA )治疗子宫肌瘤的应用价值。方法 98例拟行RFA治疗的子宫肌瘤患者,随机分为2组:CEUS组46例及3D-CPA组52例,CEUS组术前行超声造影,记录达峰期肌瘤增强程度。3D-CPA组术前行三维超声成像,记录肌瘤血流分级情况及供血血管走行,两组术后均行超声造影,比较两种方法指导下术后2h肌瘤完全消融率,术后3个月体积缩小率是否存在差异。结果 ①CEUS组与3D-CPA组中血管分布密集情况。②两种方法指导下A组与D组、B组与E组治疗后病灶完全消融率无统计学差异(P > 0.05),C组与F组完全消融率有统计学差异(P < 0.05)。?术后3个月CEUS组中肌瘤平均体积小率逐渐下降,差异有统计学意义,3D-CPA组亦然,但两种方法分别指导消融,在术后平均体积缩小率上无统计学差异(P > 0.05)结论3D-CPA同CEUS技术均能较好的指导病灶内具有丰富血管的肌瘤进行射频消融,但3D-CPA成像对细小血管的显示低于CEUS,两种检查方法分别指导射频消融,临床价值无差异。 |

Abstract: |
Objective To investigate the application value of contrast enhanced ultrasound(CEUS) and three-dimensional Color Power Angiography(3D-CPA)in the treatment of radiofrequency for uterine fibroids.Methods 98 cases of patients with uterine fibrods to RFA therapy,Randomly divided into two groups:46 cases of CEUS group and 52 cases of 3D-CPA group,the patients of CEUS group were performed on contrast-enhanced ultrasound before the operation ,recording the degree of enhancement during the peak.The patients of 3D-CPA group were performed on three-dimensional ultrasound,recording fibroids blood flow classification and blood vessels walking,two groups were performed on contrast-enhanced ultrasound after the operation.Compare the differences of the two methods under the guidance of the uterine fibroid of hours postoperatively completed ablation rate and the months postoperatively shrinkage rate. Rusults ①The ascular distribution density of 3D-CPA group and CEUS group. ②Under the guidance of the uterine fibroid ,the differences of completed ablation rate between A group and D group ,B group and E group were no statistically signicant. (P>0.05) The differences of completed ablation rate between C group and F group were statistically signicant(P<0.05). ?The months postoperatively shrinkage rate of uterine fibroids in CEUS group was gradual declining,the differences was statistically signicant,as so as 3D-CPA group,but the differences of the two methods in guiding radiofrequency ablation were no statistically signicant respectively(P>0.05). Conclusion 3D-CPA and CEUS all can better guide has rich blood vessels inside the lesions of fibroids for radiofrequency ablation,but 3D-CPA showed below CEUS of poor blood vessels.Guiding radiofrequency ablation with the two methods respectively,the application value was no difference. |
