[Doppler color ultrasonography of maternal-fetal circulation in HELLP syndrome].

The authors investigated the blood flow velocity waveforms of the mothers uterine arteries and fetal middle cerebral, renal and umbilical arteries in cases of HELLP syndrome by color Doppler ultrasonography. The elevated velocimetry indices in the uterine and umbilical arteries were the result of utero-placental and fetoplacental vascular lesions with resultant decrease in blood flow. These laid to the centralization of fetal circulation with increased blood flow in cerebral and decreased in renal arteries. All women were delivered small for gestational age infants.
