Abstract

The article is a review of the literature on the use and clinical applicability of Doppler examination in the second half of pregnancy. Nowadays, despite its accessibility, Doppler ultrasound in pregnancy is often contraindicated. At the same time, the is no evidence of clinical utility of Doppler studies in a low-risk pregnancy. The main indications for Doppler examinations in pregnancy include intrauterine growth restriction (IUGR), suspicion of fetal anemia, and complications of monochorionic twin pregnancy. As far as IUGR is concerned, Doppler allows to diagnose IUGR associated with placental insufficiency and to differentiate IUGR from small for gestational age fetuses (SGA). Doppler is also very useful in making the decision about the time of delivery of IUGR fetuses. The assessment of the peak systolic velocity in the middle cerebral artery (PSV-MVA) reduced the rate of invasive procedures due to fetal anemia by approximately 70%. Complications of the second half of pregnancy which are indications for Doppler ultrasound include selective IUGR, TTTS and TAPS. Similarly to the first trimester, the mid-trimester assessment of the blood flow in the uterine arteries plays an important role in the prediction of preeclampsia and IUGR, especially early-onset forms of these complications.
