Fetal and uteroplacental flow velocity waveforms in the expectant management of placental abruption.
نویسندگان
چکیده
The change in flow velocity waveforms was assessed by Doppler ultrasound in the course of evolution of placental separation. The velocity changes reflected a high response to blood flow in the placental circulation along with decreased cerebral vascular resistance.

Accurate assessment of gestational age, fetal growth, and the detection of fetal and placental abnormalities are major benefits of sonography. Color Doppler can be used to assist in the identification of vascular architecture, detection of vascular pathology and visualization of blood flow changes associated with physiologic processes and disease states. The clinical applications of obstetrical...

Maximum flow velocity waveforms were studied at the cardiac level (ascending aorta, pulmonary artery, and ductus arteriosus) and at the peripheral level (fetal internal carotid artery, descending aorta, umbilical artery, and maternal uteroplacental artery) in 25 patients with intrauterine growth retardation and 25 normal control subjects matched for gestational age and maternal parity. Gestatio...

متن کاملPlacental ischemia and changes in umbilical and uteroplacental arterial and venous hemodynamics.
OBJECTIVE To relate Doppler velocimetry findings in fetoplacental and uteroplacental circulation to placental histomorphology. MATERIAL AND METHODS In 14 uncomplicated and 31 high-risk pregnancies Doppler velocimetry was performed in umbilical artery and vein, and in maternal uterine veins and arteries during the second half of gestation. Histopathology of the placentas was examined, especial...
