Uteroplacental blood flow in pre-eclampsia measurements with indium-113m and a computer-linked gamma camera

Clin Exp Hypertens B. 1982;1(1):105-17. doi: 10.3109/10641958209037184.


Uteroplacental blood flow was measured with a computer-linked gamma camera after intravenous injection of 1 mCi indium-113m. Results of the measurements from 32 pre-eclamptic pregnancies and 37 normal controls are compared. The uteroplacental blood flow was measured as an index calculated from the rise time and maximum activity of the isotope accumulation curve. The uteroplacental blood flow was reduced with 50% in pre-eclampsia. In severe pre-eclampsia it was more compromised than in mild pre-eclampsia. A diminished uteroplacental blood flow was found in pre-eclampsia even in the absence of intrauterine growth retardation. The maternal placental circulation in the supine position was reduced with one third compared to that in the left lateral recumbent position.
