彩色多普勒检测黄体血流对评估胚囊发育的诊断价值

PREDICTING THE DEVELOPMENT OF EARLY GESTATION SAC BY DETECTING LUTEAL BLOOD FLOW WITH COLOR DOPPLER

目的 :经阴道彩色多普勒检测早期妊娠黄体血流阻力指数 ,作为预测胚囊正常发育的参数值。方法 :采用实验组与对照组在早孕期间 (孕 3 6d～ 65 d) ,经彩色多普勒常规检测妊娠黄体血流阻力指数后 ,对早妊胚囊分别进行临床病理检验和影像跟踪观察 ,最后筛选出病检具有正常绒毛组织和超声检测发育至 18周为正常胎儿的早妊黄体血流阻力指数值 ,做统计学处理。结果 :所测得的黄体血流阻力指数 (两组共计 60例 ) ,均能维持胚芽的正常发育。两组均值无显著性差异 ,均服从于正态分布 t=0 .0 2 63 7<0 .0 5 ,P>0 .0 5两组正态分布的总体均值是相同的。结论

Objective:To study the luteal blood resistance during normal early pregnancy and assess the normal development of gestation sac by using B mode ultrasonography.Methods:B mode ultrasonography was used to detect the luteal blood flow resistance in normal early pregnancy,and meanwhile gestation sac′s pathology and image were observed.The normal luteal blood flow resistance index was obtained for normal early pregnancy that would develop an eighteen week normal fetus.Results:The luteal blood flow resistance index can be used to predict the normal development of gestation sac.There is no significant difference between study group and control group (P>0 05).Conclusion:The luteal blood flow resistance,in a certain range,can be used as a reference factor for predicting the normal development of early gestation sac.
