Significance of cerebral and umbilical artery doppler velocimetry in normal and growth restricted pregnancy
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2017, Vol 23, Issue 1
Abstract
Background: Doppler velocimetry is a rapid non invasive test that provides valuable information about hemodynamic situation of the fetus and is an efficient diagnostic test of fetal jeopardy which helps in timely intervention and management of high risk pregnancy for better perinatal outcome. Material and Methods: This is a prospective study including 40 women with normal singleton pregnancy and 40 women with Intra uterine growth restricted pregnancy carried out over a period of 1 year from april 2015 to march 2016 at MNR Medical College and Hospital, Sangareddy. Results: Umbilical artery mean pulsatility index and resistive index were significantly greater in IUGR pregnancy as compared to normal pregnancy. Systolic/diastolic (S/D) ratios were comparable in both the groups. There was significant reduction in cerebroumbilical (C/U) ratio in IUGR pregnancy as compared to normal pregnancy suggesting presence of a brain sparing effect. 17.5% patients in study group had absent end diastolic volume (AEDV) and 2.5% had reversal of end diastolic volume. Conclusion: In normal pregnancy, there is gestational age related fall in impedance in umbilical and middle cerebral arteries. Doppler study of umbilical artery is highly sensitive in the detection of IUGR while Middle cerebral artery doppler is useful for the prediction of adverse perinatal outcome in small for gestational age.
