经阴道彩色多普勒血流显像对子宫肌瘤的子宫动脉血供的研究

分析了经病理诊断证实的子宫肌瘤102例的子宫动脉的血流动力学特点,并与30名正常成年女性进行对照。结果表明,子宫肌瘤组的血流速度增快,,外周阻力下降。RI,PI和A/B值等三项指标均明显低于正常对照组(P<0.05)。但RI值大于0.40,PI值大于1.0。作者认为,RI,PI和A/B值均不依赖声束与血流的夹角,尤其PI是以多点的均数进行计算,其误差更小。子宫动脉的血流动力学研究,将有助于对子宫肌瘤的生长速率、变性和癌前变的预测。这些参数的分析,对绝经期后子宫增大的高危人群中子宫平滑肌肉瘤的筛选具有一定价值。

Observations of the hemodynamics with a u-terine myoma by transvaginal color Doppler blood flow imaging.

This paper analysis the data of a uterine arteries hemodynamics of 65 cases with leiomyoma which were comformed bypathologic diagnosis, and compared with 30 normal adult women. Results suggest that blood flow velocity is increase and periphery, resistance is descent, in uterine myoma group. The RI,PI and A/B value are lower than normal control group(t<0. 005). ButRI>0. 4, PI>1. 0 were found in all of thepatients. Authors consider that RI, PI, and A/B value are independent on the angle of blood flow direction and ultrasound beam. Particularly, the PI is calculated on the mean of many points. Therefore, the PI is less susceptible to raridom error in the spec-tal measurements. A study on the hemody-namics of the uterine arteries have contributed predictive of growing rate, degeneration, and premalignant state. Analysis of multiparameter is valuable in the diagnosis of uterine sarcoma in high-risk groups such as postmenopausal patients with a rapidly enlarging uterus.
