OBJECTIVES: To evaluate the diagnostic value of ultrasound spectra of the middle cerebral artery (MCA) and umbilical artery (UA) blood flow in predicting adverse pregnancy outcomes.
METHODS: Data from 202 late singleton pregnancies (32-34 weeks gestation) were analyzed. Group A included 155 normal pregnancies, while Group B comprised 47 high-risk pregnancies. Color Doppler ultrasonography was used to measure and compare pulsatility index (PI), resistance index (RI), and end-systolic peak/end-diastolic peak (S/D) ratios of fetal MCA and UA between the groups.
RESULTS: UA-related parameters (PI, RI, and S/D) were significantly higher in Group B compared to Group A, whereas MCA-related parameters (PI, RI, and S/D) were significantly lower in Group B than in Group A. In pregnancies with adverse outcomes, fetal UtA and UA-related parameters were elevated, while MCA parameters were decreased compared to those with favorable outcomes.
CONCLUSIONS: Ultrasound spectra of MCA and UA blood flow provide valuable clinical information for assessing fetal intrauterine growth and predicting adverse pregnancy outcomes.
