目的:探讨早孕期胚胎停止发育及流产患者底蜕膜层的超声表现。方法:回顾152例妊娠4~12周患者的超声声像图,其中早孕期流产117例,妊娠足月者35例。对比妊娠足月及早孕期流产患者底蜕膜层的厚度及回声强度。结果:(1)与正常孕妇相比,在第5~6周流产患者,底蜕膜相对变薄。但随着时间的推移,仍然可以保持其完整性,并且回声均匀;(2)在早孕晚期流产的患者,底蜕膜层的厚度没有表现出增长的趋势;(3)在胚胎死亡之前及之后不久,蜕膜层较正常妊娠回声增强。之后胚胎解体,底蜕膜层变得难以辨认。结论:在早孕期流产患者底蜕膜层超声表现与正常妊娠患者存在差异。
Objective: To investigate the development of embryos in the first trimester of pregnancy and the decidua of abortion patients with ultrasound. Methods: The echocardiography of 152 patients with gestational age from 4 to 12 weeks was retrospectively reviewed. Among them, 117 were aborted in early pregnancy and 35 were in full-term pregnancy. To compare the thickness and echo intensity of end decidual layer of abortion patients in term term and early pregnancy. Results: (1) Compared with normal pregnant women, abortion was relatively thin at the 5th to 6th week in abortion patients. But still retain its integrity over time, with uniform echogenicity; (2) the thickness of the decidua did not show an increasing trend in patients who had abortions in the first trimester; (3) before and after embryo death Soon, decidual layer than normal pregnancy echo enhancement. After the embryos disintegrated, the end decidua became illegible. Conclusion: There is a difference between the decidua and the normal pregnancy in the abortion patients during the first trimester.
