目的探讨经阴道彩色多普勒超声(TV-CDFI)在早期宫内妊娠黄体检测中的临床应用价值。方法选取2012年2月-2015年7月在该院产科门诊就诊的156例早期妊娠妇女为研究对象,根据病理或手术诊断结果进行分组,其中正常早期宫内妊娠的48例为观察组,先兆流产但能维持妊娠的38例为对照A组;先兆流产且不能维持妊娠的28例为对照组B组;异位妊娠的42例为对照C组,比较各组妊娠黄体的二维超声声像图表现、血流特点和血流参数。结果观察组妊娠黄体的二维超声声像图特点多为厚壁双环型,对照A组和对照B组多为不均质低回声团块型,对照C组多为薄壁囊肿型,各组妊娠黄体二维超声声像图特点分布比较差异有统计学意义(u=9.458,P<0.01);TV-CDFI检查妊娠黄体观察组动脉收缩期峰值流速(PSV)明显高于其余各组(q=4.286,P<0.01);观察组阻力指数(RI)明显低于其余各组(q=3.284,P<0.01);妊娠黄体的血流特点观察组主要表现为花圈形,对照A组主要表现为半环形,对照B组主要表现为短棒形和星点形,对照C组主要表现为花圈形和半环形,各组血流特点分布情况比较差异有统计学意义(u=11.357,P<0.01)。结论 TV-CDFI检查妊娠黄体的血流在早期妊娠鉴别及预后评估中具有较高的价值。
Objective To investigate the clinical value of transvaginal color Doppler ultrasonography (TV-CDFI) in the detection of corpus luteum during early pregnancy. Methods A total of 156 early pregnancy women treated in obstetrics and gynecology department of our hospital from February 2012 to July 2015 were selected according to the pathological or surgical diagnosis results. Among them, 48 cases of normal early intrauterine pregnancy were observed group, 38 cases of miscarriage but able to maintain the pregnancy control group A; threatened abortion and can not maintain the pregnancy in 28 cases of control group B; 42 cases of ectopic pregnancy as control group C, comparing the two groups of pregnancy luteal ultrasound Figure performance, blood flow characteristics and blood flow parameters. Results The two-dimensional ultrasonographic features of pregnant corpus luteum in the observation group were mostly thick-walled double-ring type, heterogeneous hypoechoic mass type in control group A and control group B, and thin-wall cyst type in control group C. In each group, The distribution of two-dimensional echocardiography in pregnancy corpus luteum had statistical significance (u = 9.458, P <0.01). The peak systolic velocity (PSV) of the observation group was significantly higher than that of the other groups by TV-CDFI = 4.286, P <0.01). The resistance index (RI) of the observation group was significantly lower than that of the other groups (q = 3.284, P <0.01) (Control group B) showed short stubs and star spots. The control group C mainly showed wreath-like and semi-annular shape. The distribution of blood flow in each group had significant difference (u = 11.357, P < 0.01). Conclusion TV-CDFI examination of the corpus luteum blood flow in the early pregnancy identification and prognosis of high value.
