Purpose of the research is improving the early diagnosis of chronic viral hepatitis B, C and D by using of modern technologies of ultrasound scanning in children.
Material and methods of research: complex clinicо-laboratory-ultrasound inspection in 184 children. Examined children of 3 groups: with chronic viral hepatitis B (CHB), a chronic viral hepatitis C (CHC), a chronic viral hepatitis D (CHD). The surveyed groups of patients was divided according to activity of chronic viral hepatitis (minimal, moderated, expressed). Age features of complex echographic researches, including qualitative and quantity indicators of hemodynamics a liver and a spleen, also surveyed at practically healthy 40 children.
Results of research: dopplerography at children with chronic viral hepatitis B, C, D showed increase of indexes in the general hepatica and splenalis arteries that meant increase of vascular resistance in a liver and a spleen. The reasons of changes of arterial hemodynamics was development of sclerous changes in a parenchyma of body and a syndrome of portal hypertensia. Using Dopplerography at chronic viral hepatitis B, C, D successfully helped to estimate hemodynamics of a liver and a spleen. The two-dimensional echography allows to reveal increase in a liver, a spleen, change of contours of a parenchyma. 3 D technologies allow to estimate a liver in the volume image and 4 D technologies allow in volume and also in movement. The most modern method of an elastography allows to determine density of body and is a method of a noninvasive puncture. Results of researches showed that ultrasonic methods allow to estimate activity of pathological process. But the echography doesn't allow to estimate an etiology of pathological process. Activity can be minimum, moderate, expressed.
Conclusion: The important advantage of echography is the absence of ionizing radiation, due to it may be used for observing chronic viral hepatitis dynamics, to control the efficiency of pharmacotherapy and for timely diagnosis of complications.
The data enables to perfect the diagnosis the chronic viral hepatitis in children and to determine the importance of ultrasonic examinations both in complex diagnosis of chronic viral hepatitis and to control the dynamics of pathologic process.
