摘要目的 探讨彩色多普勒超声诊断前置血管的临床效果.方法 回顾性分析2010年1月至2010年12月经临床或病理确诊的30例前置血管患者的临床资料,先经腹部常规超声检查及测量,对可疑胎盘及前置血管显示不清者再行阴道超声检查并多切面观察.结果 前置血管30例,经临床诊断、病理检查确诊26例(86.67％),误诊4例(13.33％),其中3例(96.67％)前置胎盘合并前置血管诊断为前置胎盘,未观察到前置血管；1例(3.33％)帆状胎盘合并前置血管,漏诊前置血管.彩色多普勒超声下前置血管分为四型,帆状附着型14例(46.67％),副胎盘型7例(23.33％),双叶胎盘型5例(16.67％),脐带胎盘边缘附着型4例(13.33％).30例前置血管患者中阴道分娩6例(20.0％),剖宫产24例(80.0％)；活婴29例(90.63％),死胎3例(9.37％),30例中全部母亲及29例(96.67％)婴儿均康复出院.结论 彩色多普勒超声对前置血管的诊断符合率较高,可首选用于前置血管的检查,能降低新生儿病死率.

abstractsObjective To investigate the clinical effect of color doppler ultrasound on dignosis of pre-vascular.Methods The clinical data of 30 patients with pre-vascular,diagnosed by clinic or pathology,from January 2010 to December 2010,were retrospectively analyzed.The patients first received normal stomach ultrasound check and measure,and those who shoved suspicious placenta and unclear pre-vascular received vagina ultrasound check and were examined in section.Results Among the 30 cases of pre-vascular,26 cases(86.67％ ) were diagonosed by clinic and pathology,4 cases( 13.33％ ) were misdiagnosed,including 3 cases(96.67％ ) of pre-placenta with pre-vascular missed,1 case(3.33％ ) of sail-placenta with pre-vascular missed.Under color doppler ultrasound,pre-vascular was divided into 4 patterns,including 14 cases (46.67％ ) of sail-placenta,7 cases(23.33％ ) of by-placenta,5 cases( 16.67％ ) of double-leaf-palcenta and 4 cases ( 13.33％ ) of placenta with umbilical cord adhered to the edge.Among the 30 patients,6 cases (20.0％) gave birth by vagina and 24 cases(80.0％) by caesarean.Twenty-nine cases (90.63％)of living babies and 3 cases (9.37％) of still-born babies were born.Thirty mothers and 29 infants(96.67％) recovered and discharged.Conclusions The diagnosis coincidence rate of color doppler ultrasound for pre-vascular is high,so it can be used for examination of pre-vascular and can reduce the mortality of new born babies.
