胎儿脐动脉舒张末期血流失及返流的临床分析

探讨胎儿脐动脉舒张末期血流缺失,返流的产生因素及与围产儿结局的关系。方法应用脉冲多普勒超声检测胎儿脐血流,对３３例出现ＡＥＤＶ（ＡＥＤＶ组）的母儿的临床资料进行分析,并与未发生ＡＥＤＶ的４２４例进行比较。结果（１）ＡＥＤＶ组９例（２７．３％）胎儿有不同种类的形态异常,６例围产儿死亡。

Clinical analysis of the absent and/or reverse end diastolic velocity of fetal umbilical artery

OBJECTIVE: To investigate the relations between absent and/or reverse end diastolic velocity of fetal umbilical artery (AEDV) and maternal and fetal pathological factors and perinatal outcome. METHODS: To analyze the clinical informations of 33 case, with AEDV by pulse doppler ultrasonic examination. RESULTS: (1) There are 9 cases (27.3%) complicated with different kinds of fetal morphologic abnormality, 6 cases of perinatal death. (2) In 6 cases (18.2%) of twins, twin-twin transfusion syndrome (TTTS) occurred in 3 cases. In 6 cases when the body weight differences between the 2 babies were higher than 24.8%, neonatal death occurred in 4 cases. (3) The group with AEDV showed significantly higher incidence of pregnancy induced hypertension, oligoaminos, IUGR, fetal distress and neonatal death than that of normal group. CONCLUSIONS: The appearance of AEDV shows the extreme disfunction of mothermal placental-fetal circulation and may be related to poor outcome.
