早孕期绒毛膜隆起的超声表现及临床意义

目的探讨早孕期绒毛膜隆起的超声特点及其临床意义。方法回顾性分析在我院行早孕期经阴道超声检查的孕妇33 691例,其中绒毛膜隆起60例,剔除失访病例,共38例纳入绒毛膜隆起组;绒毛膜下血肿2257例,随机抽取其中365例,剔除失访病例后,共220例纳入绒毛膜下血肿组;从余下正常孕妇中随机抽取365例,剔除失访病例后,共235例纳入正常早孕组;比较各组超声图像特点;追踪绒毛膜隆起和绒毛膜下血肿孕妇妊娠结局,分析绒毛膜隆起对妊娠预后的影响。结果绒毛膜隆起表现为妊娠早期由底蜕膜面绒毛膜向妊娠囊内的局部不规则凸起,内无血流信号。38例绒毛膜隆起组中,8例胚胎停育;220例绒毛膜下血肿组中,17例胚胎停育;235例正常早孕组中,21例胚胎停育;各组胚胎停育发生率分别为21.05%、7.72%及8.93%;绒毛膜隆起组胚胎停育发生率高于绒毛膜下血肿组及正常早孕组,差异均有统计学意义(P=0.010、0.025);绒毛膜下血肿组胚胎停育发生率与正常早孕组比较,差异无统计学意义(P=0.641)。结论超声对早孕期诊断绒毛膜隆起有一定的临床应用价值。早孕期绒毛膜隆起可影响胎儿发育,造成停育。

Ultrasonic findings and clinical significance of chorionic bump in first-trimester pregnancy

Objective To investigate the sonographic features of chorionic bump in early pregnancy and its clinical significance. Methods This was a retrospective analysis. The sonographic features of chorionic bump, subchorionic hematoma and normal pregnancy by transvaginal ultrasound examination were compared. Then followed-up the pregnancy outcome and analyze its influence on pregnancy outcome. Results Chorionic bump which is an local irregular ,convex bulge from the choriodecidual surface into the first-trimester gestational sac, and there was no blood flow signal. Among 33691 cases of early pregnancy, 60 cases with chorionic bump and 2257 cases with subchorionic hematoma. The detection rate was 0.178% and 6.70% respectively. Of the 38 cases with chorionic bump, 8 (21.05%)embryo development arrested vs 17/220(7.72% )in the subchorionic hematoma group (P=0.010), and vs 21/235 (8.93%)in the normal pregnancy group( P=0.025).There were no statistical significance in the incidence of embryo development arrest between the subchorionic hematoma group and the normal pregnancy group (P=0.641).
