Hypertension in pregnancy (HIP) is a disease that pregnancy coexists with elevated blood pressure. It has adverse effects on all organs in pregnant and parturient women

resulting in complications such as placental abruption

disseminated intravascular coagulation

maternal heart

liver

renal failure

pulmonary edema

hypertensive encephalopathy and even death. Also

it may cause fetal growth restriction

oligohydramnios

premature delivery

fetal distress

nervous system injuries and even fetal death. It is one of the serious obstetric complications

and the main cause of high morbidity and mortality of pregnant women and perinatal infants. Doppler ultrasound is widely used in prenatal diagnosis because of non-invasion and low cost. It is routinely applied to monitor pregnancy complications and evaluate perinatal outcomes. The present paper reviews the application of Doppler ultrasound in hypertension in pregnancy.
