The value of ultrasound spectra of middle cerebral artery and umbilical artery blood flow in adverse pregnancy outcomes.
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.

The Journal of Perinatal Medicine (JPM) is a truly international forum covering the entire field of perinatal medicine. It is an essential news source for all those obstetricians, neonatologists, perinatologists and allied health professionals who wish to keep abreast of progress in perinatal and related research. Ahead-of-print publishing ensures fastest possible knowledge transfer. The Journal provides statements on themes of topical interest as well as information and different views on controversial topics. It also informs about the academic, organisational and political aims and objectives of the World Association of Perinatal Medicine.
