摘要
目的 探讨应用二维彩色多普勒超声观察脐带帆状附着前及附着后异常脐血管走行特点对帆状胎盘的诊断价值.方法 选择我院接受产前超声检查并诊断帆状胎盘42例,结合产后病理检查,分析其声像图特征.结果 本组病例中产前超声检查诊断帆状胎盘42例,产后病理证实帆状胎盘35例,球拍状胎盘7例,符合率83％(35/42).总结脐带帆状附着前及附着后脐血管的走行有以下表现:(1)见多处单根脐动脉与单根脐静脉伴行出入胎盘；(2)脐动脉进入胎盘前或脐静脉出胎盘后呈单根独立走行；(3)脐动脉进入胎盘前先发出分支或脐静脉出胎盘后再汇合.结论 脐带帆状附着前及附着后异常脐血管的走行可作为超声诊断帆状胎盘的线索,在提高产前超声诊断帆状胎盘的准确率方面有重要的临床价值.
Abstract
Objective To evaluate the distribution of aberrant umbilical vessels in velamentous placenta by color Doppler flow image. Methods 42 fetuses prenatally diagnosed as velamentous placenta by ultrasonography were retrospectively investigated for their sonographic features. Results 42 fetuses were diagnosed as velamentous placenta by prenatal ultrasonography. Postnatal gross appearance of placenta confirmed that 35 of them were velamentous placenta, 7 were battledore placenta. The accuracy rate is 83% (35/42). The sonographic finding of the aberrant umbilical vessels in velamentous placenta are as follow: (1) Single umbilical artery accompanying with single umbilical vein access to the placenta; (2) Umbilical artery that enter the placenta or umbilical vein that come out from the placenta runs independently ; (3) Umbilical artery sends out the branches before entering the placenta. Conclusions The distribution of aberrant umbilical vessels is a reliable clue to make the diagnosis of velamentous placenta and it has a great clinical value in improving the accuracy of prenatal ultrasonographic diagnosis velamentous placenta.
