Transvaginal color Doppler offers the potential to study uteroplacental circulation in early normal pregnancies and pregnancies associated with intrautine fibroids. A total of 62 patients (30 early pregnancies complicated by myoma and 32 normal pregnancies representing the control group) whose gestational age ranged from the 6th to the 14th week were examined. The equipment used was an Aloka color Doppler SSD-680 with 5.0 MHz curve-linear transvaginal transducer. The main uterine, radial and spiral arteries were identified in all patients. Peak systolic velocity and resistance index were measured and automatically calculated. Statistical analysis used was Student t-test. This study documents a physiological decrease in impedance in the uteroplacental circulation in pregnancy associated with fibroids, while the blood velocity of the radial arteries showed a significant increase between the 10th and 14th week of gestation.
经阴道彩色多普勒技术为研究早期正常妊娠及合并子宫平滑肌瘤妊娠的子宫胎盘循环提供了可能。共检查了62例患者（30例早期妊娠合并肌瘤，32例正常妊娠作为对照组），其孕周在6至14周之间。使用的设备是配备5.0 MHz曲线线性经阴道探头的阿洛卡彩色多普勒SSD - 680。所有患者均识别出子宫主要动脉、放射状动脉和螺旋动脉。测量并自动计算收缩期峰值流速和阻力指数。采用的统计分析方法是学生t检验。本研究记录了合并肌瘤妊娠时子宫胎盘循环阻抗的生理性降低，而放射状动脉的血流速度在妊娠第10至14周之间显著增加。
