To study the clinical value of prenatal diagnosis of umbilical cord entry abnormity (UCEA) by means of color Doppler ultrasound (CDUS).
Clinical data of sixty-four cases with confirmed umbilical cord entry abnormity were reviewed and the specific UCEA conditions and the outcomes of perinatal infants were analyzed.
Detection rates of marginal umbilical cord entry abnormity and velamentous umbilical cord entry abnormity by means of CDUS at second trimester were 94.1% and 93.8% respecdtively much higher than 80.0% and 68.8% which were those of third trimester. Discrepancy had statistical significance (P<0.05). True positive rate of prenatal diagnosis of UCEA by means of CDUS was 85.9% (55/64), and false negative rate was 14.1% (9/64). Among sixty four patients with UCEA, seventeen patients (26.6%) underwent selective caesarean delivery; twenty-six patients (35.9%) underwent emergency caesarean delivery and twenty-four patients (37.5%) had normal delivery.
Prenatal diagnosis of UCEA by means of CDUS is intuitive and accurate. It provides an evidence for determination of the best time to diagnose UCEA, and also offers a proper advice for pregnant women about delivery mode to ensure the fetus survival rate, which is clinically valuable.
探讨彩色多普勒超声（CDUS）产前诊断脐带入口异常（UCEA）的临床价值。
回顾性分析64例确诊为脐带入口异常患者的临床资料，分析脐带入口异常的具体情况及围产儿结局。
孕中期采用CDUS诊断边缘性脐带入口异常和帆状脐带入口异常的检出率分别为94.1%和93.8%，明显高于孕晚期的80.0%和68.8%，差异有统计学意义（P<0.05）。CDUS产前诊断UCEA的真阳性率为85.9%（55/64），假阴性率为14.1%（9/64）。64例UCEA患者中，17例（26.6%）行选择性剖宫产；26例（35.9%）行急诊剖宫产；24例（37.5%）经阴道分娩。
CDUS产前诊断UCEA直观、准确，为确定UCEA的最佳诊断时机提供依据，也为孕妇选择分娩方式提供恰当建议，以确保胎儿存活率，具有临床应用价值。
