Abstract.
Objectives. Ultrasound diagnosis is currently one of the leading investigation methods in uterine leiomyoma. This article presents the data of the integrated ultrasound examination of uterine arteries in uterine leiomyoma by means of transvaginal sonography combined with Dopplerometry.
Material and methods. The study involved 30 healthy subjects and 45 female patients with uterine leiomyoma. Integrated ultrasound examination was performed on the apparatus Voluson E8 (UK) with a transvaginal probe with the frequency of 3,5-9 MHz with the function of color Doppler mapping. The analysis of the blood flow velocities was made in the uterine vessels and in the dominant myoma node with the definition of maximum systolic circulation rate (MSCR), index of resistance (IR) and the type of angioarchitecture of the node.
Results. According to the data of Doppler research, we identified 4 types of angioarchitecture of the myoma node: avascular, peripheral, central and mixed. Depending on the type of node perfusion the evaluation of the growth index of uterine leiomyoma was made. The most significant indicators of the growth index of the uterus were registered in the central and mixed types of blood supply to the myoma node. The values of the uterine volumes, dominant myoma nodes, MSCR and IR in uterine and tumor vessels in different types of uterine leiomyoma are presented. The obtained data enable the definition of the nature of the morphological structure of uterine leiomyoma, the intensity of its growth in different types of angioarchitecture of the uterus, thereby providing for a differentiated approach to the treatment strategy.
Conclusion. Dopplerometry in uterine leiomyoma is a non-invasive and informative method of assessment of hemodynamic changes that accompany this pathology.
Key words: uterine leiomyoma, dopplerometry, uterine vessels.
