【摘要】 目的:探讨应用彩色多普勒超声检测胎儿腹内段脐静脉(FIUV)内径及其血流速度以评价FIUV扩张的临床意义。方法:应用彩色多普勒超声检测115例产前常规超声检查正常和37例产前常规超声检查FIUV扩张的血流情况,测量正常胎儿FIUV内径及其血流速度,测量FIUV扩张胎儿的脐静脉内径及其中24例FIUV血流速度。随访研究对象的预后至妊娠结束。FIUV内径>8 mm为异常。结果:正常组胎儿FIUV内径和FIUV血流速度随着孕龄的增加而递增。FIUV扩张组FIUV内径和FIUV血流速度均明显高于正常组胎儿,差异有统计学意义(P<0.01)。结论:FIUV扩张是高危妊娠的一种征象,可能与胎儿异常及不良妊娠结局有关。更多还原

【Abstract】 Objective:To explore the clinical significance of application of color Doppler ultrasonography in measuring the inner diameter of fetal intra-abdominal umbilical vein(FIUV) and blood flow velocity to evaluate dilation of FIUV.Methods:Color Doppler ultrasound was used to detect blood flow situations of 115 cases with normal result of ultrasonography and 37 cases with dilation of FIUV,the inner diameter and blood flow velocity of FIUV among normal fetuses were measured;the inner diameter of umbilical vein of the cases with dilation of FIUV and blood flow velocity of FIUV among 24 cases with dilation of FIUV were measured.The study objects were followed up until the end of pregnancy.The cases with inner diameter of FIUV more than 8 mm were the abnormal cases.Results:In normal group,the inner diameter and blood flow velocity of FIUV increased gradually with the increase of gestational age.The inner diameter and blood flow velocity of FIUV in FIUV dilation group were significantly higher than those in normal group(P<0.01).Conclusion:FIUV dilation is a sign of high risk pregnancy,which may be correlated with fetal abnormality and adverse pregnancy outcome.更多还原
