【摘要】：目的探讨MRI评价子宫肌瘤高强度聚焦超声消融术(HIFU)后盆底筋膜改变的价值。方法回顾性分析初次行HIFU治疗的283例子宫肌瘤患者的盆腔MRI及临床资料,观察盆腔筋膜水肿情况,记录HIFU治疗总能量、辐照时间。分析患者年龄、肌瘤情况(位置、类型、数量、体积)及HIFU治疗总能量、辐照时间与盆底筋膜改变的相关性。结果共201例(201/283,71.02%)患者HIFU后盆腔筋膜出现水肿,59.71%(169/283)为1度和2度。不同肌瘤位置患者术后盆底筋膜水肿程度差异有统计学意义(χ2=27.50,P=0.007)。患者年龄、肌瘤情况(数目、体积)与盆腔筋膜水肿程度无相关性(P均0.05);HIFU治疗总能量、辐照时间与盆腔筋膜水肿程度呈正相关(rs=0.288、0.317,P均0.001)。结论采用MRI可评价HIFU治疗子宫肌瘤引起的盆腔筋膜水肿,HIFU辐照时间、治疗总能量、子宫肌瘤位置是引起盆底筋膜水肿的主要影响因素。
[Abstract]:Objective to evaluate the value of MRI in evaluating the changes of pelvic floor fascia after high intensity focused ultrasound ablation (HIFU) of uterine leiomyoma. Methods the pelvic MRI and clinical data of 283 patients with uterine leiomyoma treated with HIFU for the first time were analyzed retrospectively and the pelvic fascial edema was observed. The total energy and irradiation time of HIFU were recorded. The patient's age, the condition of myoma (location, type, quantity, volume) and the total energy of HIFU treatment were analyzed. Results in 201 patients with HIFU, edema of pelvic fascia was found to be 59.71% and 2 degrees respectively. There were significant differences in the extent of fascia edema between patients with different sites of leiomyoma (蠂 227.50 P0. 007) after operation (蠂 227.50 P0. 007). There was no correlation between the number and volume of myoma and the degree of edema of pelvic fascia. There was a positive correlation between the irradiation time and the degree of pelvic fascial edema. Conclusion MRI can be used to evaluate the radiation time and total energy of HIFU in the treatment of pelvic fascial edema caused by uterine leiomyoma. The location of uterine leiomyoma is the main influencing factor of pelvic floor fascia edema.
