Aim of the study: to find the artery and associated Doppler index most correlated to intrauterine growth restriction as a secondary complication to maternal preeclampsia
Type of the study: case control
Methods: over almost 3 years a total of 80 pregnant women with established IUGR were collected and their fetal weight and Doppler indices were taken for umbilical artery, middle cerebral artery and fetal renal artery and stored in excel sheets for further analysis. At the end of the study partial least square fit was used to find the Doppler index in any of the 3 mentioned arteries most correlated to fetal weight. All the data collected with regard to the umbilical artery and fetal weight was standardized so to overcome the natural changes in those variables which occur as pregnancy advances.
Results: the Doppler index and the artery with highest coefficient were the fetal renal artery and its resistance index. The coefficient for this Doppler index was 6.92. In other word the resistance index in fetal renal artery has the maximum predictive as well as diagnostic value for intrauterine growth retardation. Accordingly an equation was developed between resistance in the fetal renal artery as dependent index and gestational age as independent variable. From this equation an easy applicable table was constructed in clinical practice to evaluate the severity of the growth restriction from the calculated gestational age for the fetus with measured renal resistance Doppler index evaluated in the ultrasound department
Conclusion: this study has shown that resistance index in fetal renal artery is the Doppler index most correlated to fetal weight. And from the raw data an easy applicable table may be used as an auxiliary method in evaluation of fetuses with growth restriction. Under no circumstances this table should be used alone or as a 100% reliable table as useful in evaluation of fetuses with growth restriction until its clinical significance is evaluated by further searchers and clinical studies.
