Abstract
Third-trimester Doppler velocimetry offers a timely pathophysiological information on the fetal health in high-risk pregnancy, in which conventional surveillance usually indicates compromising health at too late a stage. This prospective study compared uterine, umbilical, and middle cerebral artery Doppler measurements with perinatal outcomes, in 120 cases of high risks, in a tertiary care centre.
Methods: Observation of singleton pregnancies (30-34 weeks) in the hospital with the risks of hypertensive disorders and growth restriction. Doppler indices were measured according to the gestational norms; composite adverse outcome was measured as preterm delivery, low birth weight, low Apgar, NICU stay 24h, or perinatal death.
Results: Abnormal Doppler was found in 40% of cases where multivessel involvement predicts 80% composite adverse outcome compared to 12.5% when normal. Abnormal umbilical artery was associated with increased preterm (55.6%), low birth weight (72.2%), and perinatal death (16.7%).
Conclusions: Multivessel third-trimester Doppler is an effective stratification of perinatal risk and needs to be integrated with clinical care to maximize the time of action and minimize morbidity in resource-constrained environments.
