“…Even though blood flow in the umbilical cord is found to be normal, the fetus is likely to have already developed a slight centralization of MCA while its CPR appears to be normal. The fetus may already be undergoing nutrient and oxygen deficiency, especially in the peripheral blood vessels [13,28]. Moreover, MCA can be unexpectedly disrupted four days before fetal death, on average [29]; however, it is still considered to be the most important Doppler examination parameter for monitoring the condition of the fetus [28].…”

“…In order to accurately monitor fetal growth, ultrasound biometry (measuring the circumference of the head and abdomen and the length of the femur) should be performed every two to three weeks and the dynamics should be plotted on growth curves showing the occurrence of observed changes in fetal growth [8,9]. When IUGR fetal hypoxia is detected or suspected, the results of Doppler measurements are an integral part of monitoring [10][11][12][13].…”

“…Doppler measurements are usually performed in the following arteries: the umbilical artery (UA), the middle cerebral artery (MCA), the uterine arteries (UAs) and the ductus venosus (DV). The measurements of these blood vessels provide different information [5,[11][12][13][14]. The blood flow in the UA reflects the blood flow in the placenta.…”

Background and Objectives: Intrauterine growth restriction (IUGR) is the term used to describe a fetus whose estimated weight is less than the 10th percentile of its age growth curve. IUGR is the second most common cause of perinatal death. In many cases there is a deficiency in the standardization of optimal management, prenatal follow-up and timing of delivery. Doppler examination is the most sensitive test that can assess the condition of the fetus and indicate fetal intrauterine hypoxia. Numerous studies of the fetal intrauterine state focus on the umbilical artery and the fetal cerebral blood vessels, while the peripheral arteries have so far received insufficient attention. Materials and Methods: We present a case of an IUGR fetus monitored with a non-stress test (NST) and a Doppler examination of the fetal arteries (tibial, umbilical, middle cerebral and uterine) and the ductus venosus. In this case the first early sign of fetal hypoxia was revealed by blood flow changes in the tibial artery. Results: We hypothesize that peripheral vascular changes (in the tibial artery) may more accurately reflect the onset of deterioration in the condition of the IUGR fetus, such that peripheral blood flow monitoring ought to be employed along with other techniques already in use. Conclusion: This paper describes the clinical presentation of an early detection of late IUGR hypoxia and claims that blood flow changes in the tibial artery signal the worsening of the fetus’s condition.
