Introduction: umbilical Doppler is a fundamental tool in the diagnosis of fetal growth restriction for classifying morbidity and mortality risks and it contributes to stratify the necessary control level of obstetrical in fetuses with biometric abnormalities. Objective: to describe the perinatal outcome in preterm infants with restricted intrauterine growth. Method: 585 preterm births was the universe of this study at Ramón González Coro Teaching Hospital in Havana from July 1st, 2008 to June 30th, 2011, who underwent Doppler flowmetry before the diagnosis of low birth weight or fetal growth restriction. Results: no significant association with Doppler gestational age at birth (p= 0.675) and birth weight (p= 0.714) was shown when ANOVA was performed; but there was association with the days elapsed between the Doppler results and interruption of gestation. According to the test (X2= 23.796, df= 6 and p< 0.00), there was highly significant association of day distribution with Doppler test results. There was significant association (p= 0.013), between the results of Doppler flowmetry and neonatal morbidity. Conclusions: the absence of diastole obtained according to Doppler technique was significantly related to the occurrence of adverse perinatal outcomes such as high perinatal and neonatal morbidity. In most cases, Doppler flowmetry allowed to decide the prolongation of gestation.
