Hypertension and Uterine Artery Waveform: Recent Perspectives

Hypertension and Uterine Artery Waveform: Recent Perspectives

Pregnancy Induced Hypertension is a multisystem heterogeneous disorder occurring in 4-7% of all pregnancies. Fetal villi in the intervillous space at fetomaternal interphase show ischemic, oxidative and immune mediated damage. This chapter outlines the relation between abnormal uterine artery flow and perinatal outcome in a tertiary care center. The relationship between uterine artery Doppler pulsatility index and adverse perinatal outcome is emphasized in this chapter. Doppler ultrasound examination of the uterine arteries at 20-23 weeks gestation in women with singleton pregnancies is usually done at routine target scan. Pregnancy Induced Hypertension (PIH) was recorded in (3-7%) of all pregnancies. High pulsatility index (>95th percentile) as compared to low pulsatility Index is a good tool for the prediction of PIH (sensitivity 91.23% and specificity 99.06%, p<0.05). Uterine artery Doppler has better detection rates for early onset PIH and Intrauterine Growth Restriction (IUGR). It also has high specificity in the prediction of preterm labor and abruption of placenta.
