One hundred and thirteen (66.5%) women in this study had a normal intrauterine pregnancy with ages ranging 6 to 12 weeks of gestation. Fifty-seven (33.5%) patients were admitted to the hospital owing to clinically suspected abnormal early pregnancy. Dilatation and curettage were done on all women and tissue sample sent to the pathologist for a final diagnostic. Diagnosis of ectopic pregnancy was made on laparoscopy. Both ovaries were examined carefully by color Doppler in sonography in all patients. Color flow was used as a guide for pulsed Doppler exploration. Corpus luteum blood flow was defined as random, usually semilunar in appearance, dispersed vessels with very low impedance to blood flow. The resistive index and pulsatility index were calculated. Overall detection rate of corpus luteum blood flow in normal pregnancies was higher for the left ovary (62.6%) than for the right ovary (37.4%) (P < 0.01). The mean resistive and pulsatility indices from corpus luteum blood flow were not influenced by gestational age in normal pregnancy. The overall mean value for for resistive index was 0.452 +/- 0.04 and for pulsatility index 0.636 +/- 0.09. The overall detection rate of corpus luteum in abnormal pregnancies also was higher for the left ovary (56.7%) than for the right ovary (43.4%) (P < 0.01). The mean resistive indices from corpus luteum blood flow in patients with missed abortion was higher than in women with normal pregnancy (P < 0.01). Both resistive and pulsatility indices were higher in patients with incomplete or threatened abortion in comparison with normal pregnancy (P < 0.01). No statistically significant difference was seen in the case of anembryonic, molar, or ectopic pregnancy.
本研究中，113名（66.5%）女性为宫内正常妊娠，妊娠年龄在6至12周之间。57名（33.5%）患者因临床怀疑早期妊娠异常而入院。所有女性均接受了刮宫术，并将组织样本送检病理学家以进行最终诊断。通过腹腔镜检查诊断异位妊娠。所有患者均在超声检查中使用彩色多普勒仔细检查双侧卵巢。彩色血流用作脉冲多普勒探查的引导。黄体血流定义为随机出现，通常呈半月形，血管分散，血流阻抗极低。计算阻力指数和搏动指数。正常妊娠中，左侧卵巢黄体血流的总体检出率（62.6%）高于右侧卵巢（37.4%）（P<0.01）。正常妊娠中，黄体血流的平均阻力指数和搏动指数不受妊娠年龄影响。阻力指数的总体平均值为0.452±0.04，搏动指数为0.636±0.09。异常妊娠中，左侧卵巢黄体的总体检出率（56.7%）也高于右侧卵巢（43.4%）（P<0.01）。稽留流产患者黄体血流的平均阻力指数高于正常妊娠女性（P<0.01）。与正常妊娠相比，不全流产或先兆流产患者的阻力指数和搏动指数均较高（P<0.01）。在胚胎停育、葡萄胎或异位妊娠的情况下，未观察到统计学上的显著差异。
