[Ultrasonic diagnosis of nonimmune hydrops fetalis].

Possibilities of prenatal echographic diagnosis of nonimmune hydrops fetalis are described. This diagnosis has been made in 16 fetuses between 21 and 40 weeks of gestation. Cardiovascular disorders were detected in 8 of the 16 fetuses. It is emphasized that purposive echocardiographic screening to detect congenital heart diseases and arrhythmias is essential in fetuses with nonimmune hydrops. Congenital fetal malformations combined with nonimmune hydrops justify termination of pregnancy, as antenatal or early neonatal death will occur in most such cases.

[Value of utero-placental and feto-placental Doppler flowmetry in selecting rational tactics in the management of pregnancy and the method of delivery].

A classification of hemodynamic disorders in the mother-placenta-fetus system has been developed, and approaches to the management of pregnancy and the choice of the method and time of delivery have been evolved on the basis of a study of 134 normal pregnancies and 47 complicated pregnancies between 16 and 41 weeks. It is demonstrated that abdominal delivery is preferable for the sake of the fetus where uteroplacental and fetoplacental circulatory disturbances are considerable.

[Possibilities of Doppler ultrasonics in the study of blood flow in the iliac and ovarian arteries in healthy women].

A duplex-system echographic study, with simultaneous visualization of the vessel proper and its doppler flow rate curves, was carried out in 35 women with normal biphasic menstrual cycles. A typical flow rate curve was demonstrated for each of the vessels. The assessment of numeric pulsation index values showed its significant reduction in the ovarian artery where the ovary contains a mature follicle or a luteal body. The results obtained have been analysed in morphofunctional terms. A conclusion is made that a more accurate prediction of the ovulation and assessment of the microcirculatory ovarian bed in various diseases is possible.

[Echographic transvaginal diagnosis of pregnancy in the first trimester].

A comparative analysis of informative value of transvaginal echography and transabdominal scanning was made when 86 pregnant females were investigated in the first trimester of pregnancy. It was established that transvaginal echography could provide the investigator with a more precise and earlier assessment of pregnancy development its initial stages. If transabdominal scannings informative value turned to be insufficient, the usage of transvaginal echography in the determination of pregnancy itself and pregnancy-associated complications was found mandatory.

[The diagnostic potentials of dopplerometry in the fetal growth retardation syndrome].

Findings of conventional sonography and Doppler studies at 34-41 weeks of gestation have been compared in 210 women. Uteroplacental and fetal blood flows were evaluated in intrauterine growth retardation syndrome. Sensitivity, specificity and predictive value of these studies were assessed for fetal vessels, umbilical artery, uterine arteries and fetal measurements. Obstetric and neonatal outcomes were analyzed in relation to hemodynamic abnormalities in the maternal-placental-fetal system.

[Use of acetomepregenol in the treatment of threatened habitual miscarriage].

Monitoring for pregnancy development and treatment efficacy in 104 females treated with acetomepregenol for threatened recurrent abortion at 8 to 16 week of gestation was performed with the use of ultrasonic variations. Ultrasonic criteria characteristic of the aforementioned condition were established. The technique suggested was distinguished by high levels of sensitivity, simplicity, availability and safety for mother and fetus.
