目的探讨早期妊娠合并绒毛膜下血肿的治疗效果及超声对妊娠结局的预测价值。方法 209例早期妊娠及先兆流产孕妇经阴道超声检查发现绒毛膜下血肿,按面积比例法分为轻、中、重三种程度,据初次检查时间将孕妇分为≤8周和>8周。应用地屈孕酮治疗,超声定期复查并随访预后,对不同程度和不同检查时间的绒毛膜下血肿在孕20周前发生的自然流产进行回顾性分析。结果 209例治疗后,总的流产率为9.57%,轻、中和重绒毛膜下血肿孕妇的自然流产率分别为6.66%(9/135)、8.93%(5/56)和33.33%(6/18),轻度与中度血肿孕妇的自然流产率比较差异无统计学意义(P>0.05),轻度和中度与重度血肿孕妇的自然流产率比较差异均有统计学意义(P<0.05)。初次检查时间≤8周者自然流产率为12.19%(15/123),>8周者的自然流产率5.81%(5/86),两者比较(P<0.05)。结论超声诊断早期妊娠合并绒毛膜下血肿、评估血肿大小及治疗后定期随访对妊娠预后有重要的参考价值。 Objective To investigate the therapeutic effect of early pregnancy combined with sub-chormatoid hematoma and the predictive value of ultrasound on pregnancy outcome. Methods 209 cases of early pregnancy and threatened abortion of pregnant women by transvaginal sonography found sub-chormatoid hematoma, according to the area ratio method is divided into light, medium and heavy levels, according to the time of the first examination of pregnant women were divided into ≤ 8 weeks and> 8 weeks. Application of dydrogesterone treatment, periodic review of ultrasound and follow-up of prognosis, different degrees and different examination time subdural hematoma spontaneous abortion occurred in 20 weeks before pregnancy were retrospectively analyzed. Results After the treatment, the total abortion rate was 9.57%. The spontaneous abortion rates of pregnant women with mild, moderate and severe sub-submucous hematomas were 6.66% (9/135), 8.93% (5/56) and 33.33% (6) respectively / 18). There was no significant difference in the rate of spontaneous abortion between mild and moderate hematoma (P> 0.05). There was significant difference in spontaneous abortion between mild and moderate hematoma (P < 0.05). The spontaneous abortion rate was 12.19% (15/123) at the first examination time≤8 weeks, and 5.81% (5/86) at the 8th week. There was significant difference between the two groups (P <0.05). Conclusion Ultrasound diagnosis of early pregnancy with sub-chormatoid hematoma, assessment of hematoma size and regular follow-up after treatment have important reference value for the prognosis of pregnancy.
