The objective of this study was to investigate and determine fitted percentiles of blood flow resistance of cervical internal carotid arteries in normal pregnancies from gestational weeks 20 to 42 and to compare the resistance indices and mean velocities of the these arteries in normotensive and preeclamptic gravidas. A duplex color apparatus with pulsed Doppler ultrasound scanner (7.5 MHz) was used to determine the resistance index and mean velocity values of maternal cervical internal carotid arteries in 310 healthy singleton gravidas (group 1) and 74 singleton preeclamptic gravidas (group 2). The resistance index and mean velocity values of the maternal cervical internal carotid arteries decrease as the gestational age increases in normal gravidas, whereas in preeclamptic pregnancies these values are no different from those in normal gravidas during the second half of the gestational period. |
