摘　　要：目的 探讨彩色多普勒对早孕时妊娠部位血流检出率与妊娠着床部位关系 方法 应用美国HP-image Point对120例有停经史,尿妊娠试验阳性,自愿要求终止妊娠的患者作阴道超声检查(TVS)及腹部超声检查(TAS)。对妊娠部位血流流速和RI测量 结果 正常妊娠,孕4周+5天,能测到种植部位彩色血流,检出率92.8％,孕8-9周检出率为100％。结论 有停经史,宫内测及种植部位血流是诊断早孕的可靠依据。宫内未种植部位测及血流,有停经史,尿妊娠试验阳性,要高度怀疑宫外孕。Objective The assessment of the diagnosis of early pregnancy by color doppler Ultrasonography. Methods Transvaginal and abdominal Color Doppler(TVS,TAS) were performed in 120 pregnant women who volunteer to stop their pregnancy of the menstrual age ranged from the forth to the ninth week. Results With the combination of TVS and TAS detection, the diagnosis rate of early stage of pregnancy was obviously raised. The blood flow in the trophpblastic could be visualized with either TVS or TAS staring from as early as the forth or the fifth week. Flow velocity waveform was measured and results were analysis by calculation of resistance Index(RI). In addition, the higher value of the combination of TVS and TAS is good for the early diagnosis of ectopic pregnancy. Conclusion If the blood flow was neither detectable by TVS nor by TAS in the women whose urine test was positive for pregnancy and also with menopause history,the diagnosisof ectopc pregnancy should be significantly considered.
