Diagnostic Accuracy of Pulsatility Index Umbilical Artery and Middle Cerebral Artery in Detecting Intra Uterine Growth Restriction
Objective: To determine the diagnostic accuracy of sensitivity and specificity of the PI-UA and MCA in detecting IUGR by comparing it with the Birth weight.
Methodology: This cross sectional study was done from 01-07-2017 to 01-012018 After approval of the ethical committee on 14-06-2017. The sampling technique was non probability consective sampling technique.Total 327 pregnant women with IUGR in the third trimester were included in the study. The exclusion criterion was multiple pregnancies, Unwilling patients/ un-cooperative patients, fetal structural anomaly. There was no risk to the patient as ultrasonography is a non-invasive technique. Patients were followed up till delivery by their contact numbers. PI values of all the fetal MCA and UA were noted.
Results:.The mean age was ¬± 25 years, with a minimum of 16 and a maximum of 37 years. Maximum patients (13%) were in age 21, mean age was 25.8 ± 4.51 years. Out of all the Ultrasound diagnosed IUGR, 228 (69.7%) were having birth weight
The sensitivity of PI UA and MCA were 95.14% and 79.73%, respectively. Specificity of PI UA and MCA were 37% and 90%, respectively.
Conclusion: Raised PI value of UA is highly sensitive of IUGR, whereas the lower PI value of MCA is highly specific of IUGR and grave sign of fetal demise.
