title: [Assessment of blood flow in the middle cerebral artery and the umbilical artery in fetuses with umbilical venous pulsations].
abstract: OBJECTIVE
  Umbilical venous pulsation is an important sign of hemodynamic compromise, especially during fetal heart failure and asphyxia.
  
  
  METHODS
  The aim of this study was to determine of the blow flow in the middle cerebral artery and the umbilical artery in fetuses with umbilical venous pulsations.
  
  
  METHODS
  The investigation included 18 fetuses with signs of the intrauterine growth restriction and umbilical venous pulsations after 28th weeks of gestation. We evaluated cerebral-placental ratio (CPR) and pulsation index (PI) in the middle cerebral artery (MCA) and the umbilical artery (UA).
  
  
  RESULTS
  We observed brain sparring effect in all cases of analyzing fetuses. There were 77,8% of abnormal flow pattern in umbilical artery. 13 fetuses had a single pulsation pattern in umbilical vein and another 5 had double pulsation pattern.
  
  
  CONCLUSIONS
  The coexistence of umbilical vein pulsation and abnormal flow pattern in umbilical artery is closely related to increased perinatal mortality.
