【摘要】：目的:建立正常早孕期妊娠囊的体积参数。方法:选择正常早期单胎妊娠妇女303例,先用腹部容积探头二维模式对妊娠早期妊娠囊进行扫描,常规测量妊娠囊、卵黄囊及胚芽的大小(直径或长度)。再启用三维超声对妊娠囊进行三维图像采集,应用三维容积自动测量技术(VOCAL)测量其体积。结果:妊娠早期,随着孕周增加,妊娠囊体积、胚芽体积及卵黄囊体积均呈增长趋势;妊娠囊胚芽体积比随孕周增大逐渐减少;妊娠囊体积在孕7~10周的相邻两周之间,差异有统计学意义(P0.05);而10周与11周间,差异无统计学意义(P0.05);胚芽体积在孕7~11周的相邻两周之间,差异有统计学意义(P0.05);卵黄囊体积在早孕各孕周的相邻两孕周之间,差异无统计学意义(P0.05)。结论:利用三维超声建立正常孕早期妊娠囊的体积参数和变化规律。
[Abstract]:Objective: to establish the volume parameters of pregnancy sac in normal early pregnancy. Methods: 303 cases of normal early single pregnancy women were selected, and the size (diameter or length) of pregnancy sac, yolk sac and embryo were measured by abdominal volume probe two-dimensional model. Three-dimensional ultrasound was used to collect the three-dimensional images of pregnancy sac, and the volume of pregnancy sac was measured by using the three-dimensional volume automatic measurement technique (VOCAL). Results: in early pregnancy, with the increase of gestational weeks, the volume of pregnancy sac, germ volume and yolk sac volume increased, the ratio of embryo bud volume of pregnancy sac decreased gradually with the increase of gestational week, and the volume of pregnancy sac was between the next two weeks after 7 ~ 10 weeks of gestation. The difference was statistically significant (P 0.05), but there was no significant difference between 10 weeks and 11 weeks. The germ volume was significantly different between the adjacent two weeks of 711 weeks gestation, and the yolk sac volume was between the adjacent two weeks of each gestational week in early pregnancy. The difference was not statistically significant (P 0.05). Conclusion: the volume parameters and changes of normal pregnancy sac were established by three-dimensional ultrasound.
