Abstract
Способ оценки фиброза печени путем определения ее эластичности, отличающийся тем, что эластичность печени определяют на основании анализа характеристик общего и пульсового кровенаполнения печени, получаемых с помощью полигепатографии по результатам измерений электрического импеданса тела, в частности, амплитуды, формы волн кровенаполнения, базового сопротивления тела в области печени и их изменения при проведении функциональных проб задержкой дыхания на вдохе или нитроглицерином; ! при амплитуде волн выше 0,1 Ом, базовом сопротивлении не выше 100 Ом, форме волны "нормального" вида или принявший форму «нормального» вида, при выполнении хотя бы одной из функциональных проб, определяют отсутствие фиброза; ! при амплитуде волн выше 0,1 Ом, базовом сопротивлении не выше 120 Ом, форме волны нормального вида "с плато" в начале систолического подъема, которое сохраняется при функциональной пробе нитроглицерином, оценивают фиброз печени как перипортальный; ! при базовом сопротивлении не выше 140 Ом, форме волны "артерио-венного" вида, не имеющей тенденции к изменению в направлении формы нормального вида при функциональной пробе нитроглицерином, оценивают фиброз печени как портопортальный; ! при базовом сопротивлении не ниже 120 Ом, форме волны "артерио-венного" вида с уплощенной диастолой, с тенденцией к изменению в направлении формы нормального вида хотя бы при одной из функциональных проб, оценивают фиброз печени как портоцентральный; ! при амплитуде не выше 0.1 Ом базовом сопротивлении выше 150 Ом, форме волны "артериовенного" вида с уплощенной диастолой, не имеющей тенденции к изменению в направлении формы нормального � A method for assessing liver fibrosis by determining its elasticity, characterized in that the elasticity of the liver is determined on the basis of an analysis of the characteristics of the general and pulse blood supply to the liver obtained by polyhepatography based on measurements of the electrical impedance of the body, in particular, the amplitude, shape of the blood supply wave, and the basic resistance of the body in areas of the liver and their changes during functional tests by holding the breath by inspiration or nitroglycerin; ! when the wave amplitude is above 0.1 Ohm, the base resistance is not higher than 100 Ohm, the waveform of the "normal" type or has taken the form of a "normal" type, when performing at least one of the functional tests, determine the absence of fibrosis; ! when the wave amplitude is above 0.1 Ohm, the base resistance is not higher than 120 Ohm, the normal waveform is "from a plateau" at the beginning of the systolic rise, which is preserved during the functional test with nitroglycerin, liver fibrosis is evaluated as periportal; ! with a basic resistance of not higher than 140 Ohms, a waveform of an "arterial" type that does not tend to change in the direction of the normal form during a functional test with nitroglycerin, liver fibrosis is evaluated as portoportal; ! with a basic resistance of at least 120 Ohms, a waveform of an “arterial” type with a flattened diastole, with a tendency to change in the direction of the normal form, at least with one of the functional tests, liver fibrosis is evaluated as portocentric; ! with an amplitude of not higher than 0.1 Ohm, the base resistance is higher than 150 Ohm, the waveform of an “arterial” type with a flattened diastole, which does not tend to change in the direction of the normal �
