title: [Clinical analysis of the absent and/or reverse end diastolic velocity of fetal umbilical artery].
abstract: 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.
