Gestational hypertension (GHTN), formerly known as pregnancy induced hypertension, is defined as a new rise in blood pressure (BP) ≥140/90mm Hg, presenting at or after 20 weeks gestation without significant proteinuria (≥ 300mg/24 hour urine collection of urine, or 2 specimens of urine collected ≥ 4 hours apart with ≥ 2+ on the protein reagent strip. It is the most frequent cause of hypertension during pregnancy, constituting approximately 70%, and complicating about 6–17% pregnancies in healthy nulliparous women and 2–4% in multiparous women1. According to World Health Organization, Pregnancy Induced Hypertension(PIH) is one of the main causes of maternal, fetal and neonatal mortality and morbidity. The condition is estimated to account for 10% to 15% of maternal deaths worldwide. Disorders of high blood pressure are the second leading cause of stillbirths and early neonatal deaths in developing countries. Predicting Pregnancy Induced Hypertension(PIH) and treating the condition early will reduce the maternal as well as perinatal mortality and morbidity. Mean Arterial Pressure (MAP), Uterine Artery Pulsatality Index (UtA PI), Resistive Index (RI) and Systolic/Diastolic (S/D) ratio are an effective screening tools to identify the risk of PIH through uSG done in I and II trimester of pregnancy.
