RATIO OF THE FETAL UMBILICAL ARTERIAL BLOOD VESSEL TO THE MIDDLE CEREBRAL ARTERIAL BLOOD VESSEL AS A PREDICTOR OF BAD PERI-NATAL CONSEQUENCE IN HIGH-RISK PREGNANCIES

Abstract

Background: The utero-placental blood-flow and fetal responses to physiologic stressors can be determined by measuring blood-flow velocities in maternal and fetal arteries. In at-risk pregnancies, Doppler examinations of the umbilical arterial blood vessel and fetal middle cerebral arterial blood vessel are particularly effective for monitoring foetuses with early-onset growth restriction and fetal anaemia.

Aim: To determine the function of these blood-flow indicators in the prediction of adverse fetal consequence in high-risk pregnancies, researchers looked examined the ratio of middle cerebral to umbilical arterial blood vessel blood velocity.

Material and Methods: A total of 400 full-term pregnant women were enrolled in the research. For high-risk pregnancies, Doppler velocity waveforms of the umbilical and middle cerebral arteries were collected. The severity of abnormal peri-natal consequences was assessed and associated.

Results: A high MCA/UC PI ratio was linked to poor peri-natal consequences such as thick meconium stained liquor, Apgar 7 at 5 minutes, respiratory difficulties within 72 hours, NICU admission within 72 hours, and small for age.

Conclusion: An abnormal MCA/UC PI and RI ratio was discovered to be linked to a poor peri-natal consequence. In high-risk pregnancies, aberrant Doppler velocimetry indices are a good predictor of poor peri-natal consequences.
