[Placental scintigraphy--a diagnostic method for evaluating indications for hyperbaric oxygenation in pregnant women with high risk of perinatal pathology].

At most, 40 pregnant females at a high risk for fetal perinatal pathology underwent clinical investigation, ultrasonic scanning of the placenta, recording of the fetal electro- and phonocardiography, the evaluation of the placental levels of lactogen and estradiol and thermoresistant alkaline phosphatase changes of the values considered who were then treated with hyperbaric oxygenation (HBO) under the control of dynamic placental scintigraphy. Based on the placentographic findings, the authors distinguished from the whole of the risk-group the patients whose pattern of uteroplacental blood flow response to the treatment was beneficial and therefore the HBO treatment for fetoplacental insufficiency was advisable.
