Method for the diagnosis of delayed fetal development

 

(57) Abstract:

The method can be used in medicine, namely in obstetrics. Spend Doppler mapping and determine the nature of blood flow in the radial and spiral uteroplacental arteries. With increasing indexes pulsations in these arteries compared with the same data in healthy pregnant patient is referred to the risk of delayed development of the fetus in the later stages of pregnancy. The method improves the accuracy of diagnosis.

The invention relates to medicine, namely to obstetrics.

Diagnosis of complications of pregnancy in the first trimester (threatened miscarriage, frozen pregnancy and other) based on the complaints of the patient, data inspection gynecologist and ultrasound examination of the pelvic organs.

It is established that the pathology of the second and third trimesters (placental insufficiency, fetal development, fetal hypoxia, and others ) is often a result of violation of uteroplacental blood flow in the early stages of gestation [1].

The accuracy of the diagnosis of complicated pregnancy, resulting in stunting of locationone allows you to visualize the blood flow in the vessels and to estimate its parameters: direction, the speed and nature [3]. However, the known methods do not allow sufficient accuracy to predict the fetal development in the second and third trimesters of pregnancy.

The basis of the invention is the task of forecasting complicated pregnancy on early terms for definition of tactics of treatment of the patient, the choice of the most rational therapy aimed at correcting violations.

The invention consists in that in the method for the diagnosis of delayed development of the fetus by ultrasound of the uterus, including Doppler mapping of the vessels of the uterus and determining the status of their blood supply on the basis of the index ripple additionally spend Doppler mapping and determination of the nature of blood flow in the radial and spiral uteroplacental arteries and with increasing indexes pulsations in these arteries compared with the same data in healthy pregnant patient is referred to the risk of delayed development of the fetus in the later stages of pregnancy.

As a result, the method allows to predict the fetal development, placental insufficiency in the second Tr is the first study of the pregnant uterus in the early stages of gestation perform color Doppler mapping of the vessels of the uterus (uterine arteries, the right and left). Then determine the index of pulsation in the radial and spiral arteries. When pronounced asymmetry of blood flow in the right and left uterine arteries, the increase of indexes of pulsation in the radial and spiral arteries, the patient is at risk of delayed development of the fetus at a later time. Thus, the decrease in the pulsation in the radial and spiral arteries in early pregnancy serves as a prognostic sign of the occurrence of delayed fetal development.

The data obtained indicate that the performance of the index ripple in complicated pregnancy (the threat of termination, the combination of pregnancy with extragenital pathology and others) statistically significant change in uterine, radial and spiral arteries. With further prolongation of pregnancy in the group impaired uteroplacental blood flow, often develop complications such as fetal development and placental insufficiency.

Example 1.

The patient Arkhangelsk, P., 31, was admitted to the gynecological Department CCH 29 with complaints about the poor bloody discharge from the genital tract. After holding on the ANOVA pelvis. Diagnosed with uterine pregnancy for a period of 10 weeks. The research on uteroplacental blood flow using color Doppler mapping. In the mother, radial and spiral arteries performance indexes surge exceeded (index ripple >1,8) the average value for a given period of gestation, which allowed us to classify the patient at increased risk for the development of pregnancy complications. After the treatment, aimed at preserving the pregnancy, the patient was discharged from the hospital with progressive pregnancy. During the pregnancy she was held ULTRASOUND study with compulsory pyometria and Doppler flow study. During the period of 27 weeks by ultrasound found stunted fetus at 2 weeks compared with the gestational period. Was exhibited: the diagnosis of fetal development 1 degree, in connection with which a pregnant woman was hospitalized in the Department of pathology of pregnancy, maternity place of residence, where he received appropriate treatment of this pathology.

Example 2.

The patient Morozova O. Century, 30 years, was admitted to the gynecological Department CCH 29 complaints dragging pain in the lower abdomen. religious site 9.5 cm). According to doplerometry index ripple in the uterine arteries was 2,35 in the right and 2,71 on the left. Index values of pulsation in the radial and spiral arteries also exceeded (>1) the average values of the same indices in comparison with the same indicators in women with uncomplicated pregnancy. After the treatment, aimed at preserving the pregnancy, written under the supervision of a doctor of female consultation. Rodorazresheniye in the period 35-36 weeks by caesarean section on wire placental insufficiency, the initial signs of hypoxia.

SUBSTANCE: method involves examining eyeball and retrobulbary space by means of ultrasonic scanner. Ultrasonic gray scale orbit scanning is applied in real-time mode to determine ultrasonic eye reposition. Positive ultrasonic eye reposition is determined and normal state is diagnosed when recording mobile unchanged shape and free oscillation orbit tissue movements. Changes in shape, contours and size of the eyeball and immobility of orbit tissues being recorded, negative ultrasonic reposition is determined and solid full-tissue neoplasms and structures are diagnosed to occur.

EFFECT: high objectivity of received data; accelerated examination; high accuracy of differential diagnosis.

SUBSTANCE: method involves measuring uniform ampoule-like enlargement area of nerve trunk smoothly transforming itself into hypoechogenic formation with smooth distinct outline of no longitudinal striation echo-structure in longitudinal projection and enlarged rounded hypoechogenic region with changed echo-structure without granularity in transverse projection observed in visualizing the nerve trunk enlargement in transverse scanning mode. Area of zone proximally located 3-4 cm far from lesion region. Asymmetry coefficient is determined as ratio of the values. The coefficient value being greater than 2.4, terminal neuroma is diagnosed witnessing complete nerve rupture. When visualizing the single side nerve boundary enlargement in both projections with hypoechogenic zone of disturbed echogenicity structure and retained nerve segment unchanged at this level under asymmetry coefficient value being less than 2.4, lateral neuroma is diagnosed to be the case witnessing partial nerve rupture. When finding zone of linear striation echo-structure in longitudinal scanning mode and showing echo-structure granularity in transverse scanning mode not greater than 1.7 times proximal zone area 2-6 months later after the operation, fascicle nerve structure recovery in suture vicinity is considered to take place. Ampoule-like enlarged, hypoechogenic formation having partially disturbed inhomogeneous heterogeneous structure 1.7 times greater than proximal zone area being found within this period, intensive nerve trunk connective tissue elements proliferation and intratrunk neuroma is proved to be the case.

EFFECT: high accuracy in determining nerve injury degree; enhanced effectiveness in controlling postoperative nerve fiber recovery.
