To evaluate whether the assessment of tubal blood flow can indicate the side of the total pregnancy.
Using transvaginal color Doppler ultrasonography, we measured blood flow in the total arteries on both sides in 46 women with early ectopic pregnancy. We compared the resistance index (RI) and pulsatility index (PI) values of the tubal artery flow on the tubal pregnancy side to the contralateral side.
The Resistance index (RI) and Pulsatility index (PI) values were lower at the tubal pregnancy side in 70% and 61%, respectively, when compared with the contralateral side. However, in the mean values of RI and PI the difference between the sides was not statistically significant. During the follow up in cases with spontaneous resolution between-side difference was often subjected to changes.
Assessment of tubal blood flow by using transvaginal color Doppler sonography to the evaluation of the side of tubal pregnancy has limited clinical value.
评估输卵管血流评估能否提示妊娠侧别。
采用经阴道彩色多普勒超声，测量46例早期异位妊娠女性双侧输卵管动脉血流。比较输卵管妊娠侧与对侧输卵管动脉血流的阻力指数（RI）和搏动指数（PI）值。
与对侧相比，输卵管妊娠侧的阻力指数（RI）和搏动指数（PI）值分别在70%和61%的病例中较低。然而，RI和PI的均值在两侧之间差异无统计学意义。在自然转归病例的随访过程中，两侧差异常发生变化。
经阴道彩色多普勒超声评估输卵管血流对判断输卵管妊娠侧别具有有限的临床价值。
