摘　　要：目的探讨早孕期妊娠囊平均直径与头臀长之差(mGSD-CRL)对妊娠结局及妊娠期并发症的影响。方法选取1314例早孕期超声提示孕6^(+0)~8^(+6)周的单活胎孕妇为研究对象,按照mGSD-CRL分为不同组别(≤5.00 mm、5.01~10.00 mm、10.01~15.00 mm、15.01~20.00 mm、>20.00 mm),比较各组间早孕期胎停育发生率;对顺利分娩的1032例孕妇,同样根据早孕期mGSD-CRL分为不同组别(≤5.00 mm、5.01~10.00 mm、10.01~15.00 mm、15.01~20.00 mm、>20.00 mm),回顾性分析各组间妊娠期并发症发生率及分娩结局。结果①当mGSD-CRL≤5 mm时早孕期胎停育率显著升高;当520.00 mm时,胎停育率又呈上升趋势。②早孕期不同mGSD-CRL妊娠期并发症发生率及分娩结局差异无统计学意义。结论mGSD-CRL≤5 mm早孕期胎停育率发生率高,mGSD相对于CRL过大或者过小时应密切监测和随访;但早孕期mGSD-CRL不同对妊娠期并发症发生率及分娩结局无影响。Objective To explored the impact of the difference between the mean gestational sac diameter and crown-rump length(mGSD-CRL)in early pregnancy on pregnancy outcomes and pregnancy-related complications.Methods 1314 pregnant women with a single live fetus,who had their first ultrasound examination between 6~(+0)and 8~(+6)weeks of gestation and were registered in our hospital,were selected as the research subjects.They were divided into different groups based on the mGSD-CRL values(≤5.00 mm,5.01~10.00 mm,10.01~15.00 mm,15.01~20.00 mm,and>20.00 mm).The incidence of early pregnancy fetal arrest was compared between the groups.Among the 1032 pregnant women who had successful deliveries,they were also categorized into different groups according to their early pregnancy mGSD-CRL values(≤5.00 mm,5.01~10.00 mm,10.01~15.00 mm,15.01~20.00 mm,and>20.00 mm).The incidence of pregnancy complications and delivery outcomes between the groups were analyzed retrospectively.Results(1)When mGSD-CRL≤5 mm,the rate of early pregnancy fetal arrest increased significantly.When 520.00 mm,the rate of fetal arrest showed an upward trend again.(2)There was no statistically significant difference in the incidence of pregnancy complications and delivery outcomes among different mGSD-CRL groups in early pregnancy.Conclusions The incidence of early pregnancy fetal arrest is high when mGSD-CRL is≤5 mm,and mGSD should be closely monitored and follow-up when the mGSD is relatively too large or too small compared to the CRL.However,different mGSD-CRL values in early pregnancy has no effect on the incidence of pregnancy complications and delivery outcomes.
