ULTRASOUND EXAMINATION POSSIBILITIES IN ADENOMYOSIS DIAGNOSTICS IN PATIENTS WITH REPRODUCTIVE LOSS

Aim.The research was designed to study the possibilities of ultrasound examination with Color Doppler imaging (CDI) and three-dimensional volumetric reconstruction (3D) in the diagnostics of adenomyosis of minimal prevalence in patients with unspecified infertility and reproductive losses at the early stages of gestation.Materials and methods.40 patients with unspecified infertility and early pregnancy loss (the main group) and 35 healthy patients (the control group) were examined in the course of the study. All patients underwent small pelvic ultrasound in В / CDI / 3D-modes with an assessment of the junctional zone (JZ) on days 5-7 and 18-22 of the menstrual cycle (MC).Results.In the main group, there was a discrepancy between the structure of the endometrium and the phase of the cycle at 5-7 days of the MC, a decrease in vascularization of the JZ at 18-22 days of the MC, a local increase in blood flow in the endometrium in phases 1 and 2 of the MC; the fuzziness of the junctional zone, an increase in min and max thickness of the junctional zone, the difference between them, as well as the ratio of max thickness of the junctional zone to the thickness of the uterus wall regardless of the phase of the MC (p = 0.005; 0.0001; 0.005; 0.03; 0.0004; 0, 0001; 0.0001; 0.0001; 0.0001 respectively).Conclusion.Ultrasonography with the CDI and 3D reconstruction allows us to identify a high-risk group by the presence of a minimal prevalence of adenomyosis in the patients with unspecified infertility and reproductive losses at the early stages of gestation.

Background/Aim. Any organs functioning directly depends on vascularization. It applies also to the uterus and ovary which go through changes of vascularization during a menstruation cycle. The aim of this investigation was to determine differences in intrauterine and ovarian stromal arterioral blood flow on basal ultrasound examination (day 2-4) between spontaneous ovulatory and anovulatory cycles. Methods. This prospective clinical investigation included 205 patients divided into two groups: with ovulatory and with anovulatory cycles. Results. Resistance to ovarian arterioral stromal blood flow was significantly lower in the patients with ovulatory cycles (pulsatile index - PI 0.97 ? 0.4 vs 1.93 ? 1.37; p = 0.001737; and (resistance index - RI 0.55 ? 0.12 vs 0.68 ? 0.14; p = 0.040033). There were no statistically significant differences in arcuate arterioral blood flow in the pateints with ovulatory and anovulatory cycles (PI 1.21 ? 0.34 vs 61 ? 0,61 p = 0.136161 and RI 0.64 ? 0.11 vs 0.74 ? 0.07; p = 0.136649). The patients with ovulatory cycles had lower uterine radial arterioral blood flow than the patients with anovulatory cycles (PI 1.001 ? 0.22 vs 1.61 ? 0.23 p = 0.007501 and RI 0.55 ? 0.08 vs 0.71 ? 0.12; p = 0,0460113). The patients with ovulatory cycles had lower subendometrial arterioral blood flow resistance (PI 0.69 ? 0.19 vs 1.385?0.09; p = 0.00622 and RI 0.44 ? 0.09 vs 0.65 ? 0.02; p = 0.027458). Conclusion. Color Doppler ultrasuond imaging and measurements of intrauterine and ovarian stromal arterioral blood flow on basal ultrasound examination (day 2-4), showed lower resistance to blood flow in ovulatory than in anovulatory cycles.

Level Of Significance

Ultrasound examination of the skin was performed on 63 women, using a 10–22 MHz high frequency linear transducer on the scanning surface in B-mode and Color Doppler Imaging (CDI) mode with the scanning depth of 7 mm, as well as a 6–18 MHz transducer in B-mode with the scanning depth of 15 mm. The thickness of the dermis was measured between the epidermis and the subcutaneous adipose tissue in the middle and lower third of the face at standard points. To determine the border between the dermis and hypodermis, we used the subdermal vascular plexus as an additional anatomical landmark, which was well visualized in the CDI mode. Comparison of three or more groups of independent quantitative parameters was carried out using ANOVA (Analysis of Variance) for looking for dependencies in the data obtained by determining the significance of differences in means. The level of significance was presented according to F. Fisher’s criterion. As a result of the analysis of variance, a significance level was 0.15, based on which it was concluded that there is no difference in measuring the thickness of the dermis with 6–18 MHz and 10–22 MHz high frequency transducers. The optimal scanning depth for measuring the skin thickness is 7–15 mm. Evaluation of the skin microcirculation should be carried out in the Doppler mode at a pulse recurrence frequency of less than 1 kHz.
