УЛЬТРАЗВУКОВІ ГЕМОДИНАМІЧНІ КРИТЕРІЇ АРТЕРІЙ ЯЗИКА У ЗДОРОВИХ ОСІБ

Actuality of theme . In modern conditions ultrasound is a new method of functional examination of dental patients. Research of authors demonstrated that modern ultrasound equipment enabling to registrate blood flow and hemodynamic measurements in smaller arteries, which include a. profunda linguae. However, nowdays there are no indicators of the Doppler spectrum, on the basis of which could be judge about nature of the blood supply of the tongue in norm and pathology.    The purpose of the study is to develop criteria ultrasound arterial hemodynamics of the tongue in B - regime combined with color Doppler mapping and Doppler in healthy young adults. М aterials and methods of research . Conducted Echographic study of a. Profunda linguae in 42 healthy individuals aged from 20 to 26 years (20 men and 22 women) with absence of tongue’s disease. The study was conducted in triplex mode scanning in combination image in B - regime color flow cartograms and analysis of blood flow on ultrasound scanner MyLab 50 xvision firm ESAOTE (Italy) with a linear transducer, a frequency of 20 MHz and a diameter of working part 1.5 mm. The patient was offered to open his mouth and tongue to push as much as possible, which after drying cotton swab applied a special gel. Linear sensor installed on the back of the tongue, in the projection of a. Profunda linguae, so that the angle between the longitudinal axis of the vessel and the ultrasonic beam direction was 50o. Search of vessels performed using B - regime of color mapping. After Doppler blood flow imaging was performed and determined its qualitative and quantitative parameters. Evaluated qualitative and quantitative parameters: Doppler curve shape, the presence of spectral window, the intensity of luminescence various areas of the Doppler spectrum, performance V-max, TAMAX, Ri, Pi, S / D, SV by standard methods. Results of research . Average values of peak local blood flow (V-max) is 0,37 ± 0,04 m / s, the difference in performance within wide limits (from 0.12 to 1.03 m / s), the time-averaged maximum velocity of of blood flow (TAMAX) - 0,305 ± 0,022 m / s. Calculated according to the linear parameters vascular resistance index (Ri) and pulsations (Pi), which indirectly reflect the state of peripheral blood flow resistance, were on average 0,696 ± 0,01 and 1,8 ± 0,063. Indicator of systolic-diastolic ratio (S / D) in healthy individuals was 3,22 ± 0,106, most informative volumetric rate of blood circulation in the arteries of the tongue - 21,9 ± 0,2 ml / min. Color and pulsed wave Doppler is informative, non-invasive method for determining the hemodynamic status of the tongue’s arteries. Qualitative and quantitative indicators of Doppler studies after decoding can be used as a criterion for the state of ultrasound blood flow in the tissues of the tongue. Conclusion. Indicators of normal blood circulation in the bloodstream of the tongue received during ultrasonography combined with color Doppler mapping and Doppler can serve as a basis in the diagnosis and treatment of pathological processes in the tissues of the tongue of various origins.
